Radio ratings, which give some idea about how many listeners a station has, have been around since 1930. A researcher named Archibald Crossley ran the first company to use survey methods to determine audience size, although only on network programs— the so-called “Crossley Ratings.” There were other companies too— some used telephone surveys, some used mail-in surveys, others used in-person interviews, etc. Until fairly recently (2013), the vast majority of US radio stations (both AM and FM) were rated by a company called Arbitron. For many years, Arbitron used a “diary method”, where random users in major, medium and small markets were surveyed as to what they listened to during the specific period of the survey; they wrote down their listening habits on a form, and then they submitted the completed diary to Arbitron, which compiled the results into what was called “the Book” by radio stations. (“How did you do in the Book?” was radio talk for “Did you get good ratings during this rating period?”)In 2013, Nielsen, which had previously been known for television ratings, purchased Arbitron. Now, radio stations are surveyed by Nielsen, which does not use a paper diary any more. The preferred survey method now is “portable people meters” (PPM) which compile a person’s listening habits electronically. Individuals are still surveyed randomly; a specific number are contacted in each major, large, medium, and small market (city). Many people think the PPM is more accurate and easier to use than asking people to fill out a diary for a week or two. But others believe the PPM results are not as accurate, or that they favor younger formats (where the diary method favored older formats, since older people were more likely to fill their diaries out). Here is a link to a 2015 article about all of this, written by a very knowledgeable radio colleague of mine: Inconsistent Nielsen data vexes public radio stations and inspires a commercial solution

Did you know that a million dollars in U.S. currency weighs just ten kilograms? It's true. A freshly-minted $100 bill weighs in at slightly over a gram, and 100 of them is ten thousand dollars. 100 of those stacks, and there's your million.It’s not often that 10 kilograms - 22 lbs of anything can change your life. But on February 25th, 2014, that’s exactly what happened.  Day 1: $1,000,000 As the man in the gray suit walks away, I shout after him “Hey, come back here. Who are you? What’s this all about?” He does not look back and quickens his pace. Between the choice of chasing down a stranger, or securing what appeared to be stacks of currency, I chose the currency. We can resolve the issue of his identity later, but a loose sack of cash is, well, a loose sack of cash. I look through the contents again. Bundles of US$100 bills, stacked a hundred bills deep, wrapped in standard $10,000 bank bands. A quick count revealed that there were precisely a hundred of those stacks in the bag, and spot-check riffle-counts of the $10k bands suggest that there are no short-stacks within. These were full bands of $10,000 apiece of non sequential USD$100 bills, and I was holding what appears to be a million even in cash. And it feels like just as many question are swirling in my head, as I feel my pulse pounding in my skull. Who was that guy? Why me? What is this all about? But the most urgent thoughts swim past the dizzying deluge of unanswerable questions. Fakes. It’s one thing to inadvertently be the recipient of counterfeit currency; as you’re reading this very sentence, a clerk at a retail store somewhere in your city just accepted a counterfeit bill and made change from the real money in the till.  But to be in possession of a life-changing amount of counterfeit currency of the United States of America? Well, that’s sort of thing that can bring the full might and wrath of their law enforcement apparatus on your head. My emotions swing wildly between the elation of instantaneous wealth, and sheer terror that I was minutes away from being snatched from my home and corralled into a Federal holding cell, where I will grow old within its walls. Terror was the stronger of the two emotions, and I quickly went to work. First things first: the bag had to go. If there is a GPS tracking device embedded in its seams, it would take too long for me to root it out. Better to incinerate it, and make sure that whatever trail it was laying stops at a dead-end for its pursuers. I pour the stacks of bills into an empty duffle back from my garage, and lock the bag in my condo. There’s an abandoned marina just a mile from my home and I get in my car and drive straight to the docks, at the top of the posted speed limit. After pouring enough Kerosene on the bag to see the shimmering mist of petroleum evaporate above it, I lit a book of matches and threw it in the middle of the mass. A satisfying “Whoomph” lights up the fire, and I watch the edges of the bag curl and burn - sizzling in the midmorning sun. As the remnants of the bag’s embers swirl around the scorched mark on the docks, I drive back to my condo, pulse still pounding in my skull.I still haven’t figured out if the bills are real or not, but if this morning’s bag-drop was an attempt to pin a piece of deeply incriminating evidence bearing a tracking device … well that plan has been thwarted. Or delayed, at the very least. What do I do? What should I do? Call the authorities? Consider how it would sound: “Hi, Police? Somebody dropped a million dollars in cash at my home. I don’t know if it’s fake or not. Please help.” Would you believe such a ridiculous story? I wouldn't. Any reasonable law enforcement dispatcher would consider the caller legally insane, and I'd be arrested on the spot and sent to psychiatric care. If the money was real, it’d be seized and I'll never see it or spend it. If it was fake, they’d find a way to stick “possession of counterfeit currency” charge on me, and I'll be shoved into a Federal concrete box, draining the best years of my life away, only to be released when I can’t chew solid food any more. No. The only recourse is to handle this myself. I call an old college friend practicing criminal defense law in New York City: “Hey Roger, it’s Kai. How’ve you been?” “I'm cool. It's been a while. What’s up man.” “We should catch up soon in person. But I’m calling because I need something.” “Ok, shoot.” I swallow hard - it’s difficult to even say the words: “Who’s the best CrimDef lawyer you know in California, who defends against Federal charges?” A moment. His voice lowers noticeably. “Shit, man. You in some kind of trouble?” “I’m not sure yet.” I said, truthfully. “But I need someone experienced and smart ... someone who you’d hire, if you’re facing serious attention from the Feds." He lets out a long exhale. “Vincent King. Former rockstar DOJ prosecutor in D.C. Had a change of heart halfway through his rotation in Maryland, when he was securing Life sentences for “interstate drug transportation” charges on young Black kids who were busted muling for the cartels. Was offered a fast-track promotion straight to the U.S. Attorney’s office but went rogue. He set up independent shop in San Francisco, fighting Fed cases. Heavy hitter clients, but makes a point of refusing to represent anyone accused of murder or human trafficking. Intimate knowledge of Federal prosecutorial procedures and evidence-collection protocol. Smart. Methodical. Very expensive.” “Perfect.” “I did mention ‘very expensive?’” “You did.” “I’ll send his contact information now.” =================================“I’m sorry - Mr. King is in court all day and won’t be back in the office. His earliest appointment is tomorrow morning after a client meeting. Shall I book him for 11am for you?” “Yes, thank you Marta.” “We’ll see you tomorrow at 11 then.” I look at the digital clock in my kitchen -  it reads 10:44am. Just me and a stack of bills which may or may not be fake, no formal legal representation for over 24 hours. It’s going to be a long day. Taking even a few of these bills to a bank to corroborate their authenticity is out of the question. If a bank officer confirms they are fraudulent, I’ll be arrested on the spot, and since I haven’t hired counsel, I’d be at the mercy of the Public Defender’s Office - the most overworked and underpaid division of the American Criminal Justice system. No, thank you. The next number I dial is an old friend, Robert Kendrick, sole proprietor of ‘Secher Nbiw - The Golden Path,’ a gold bullion dealer with a whimsical Dune reference in the name of his shop. I’ve known Robert for over a decade; his business deals in large amounts of (mostly) legal cash. By necessity, he has a high-end currency counter/ counterfeit detection device in his office, which can swiftly count and verify large sums of money with precision. “Bobby, it’s me.” “Hey, what’s up.” “Can I come to your office - like right now?” “Sure, what do you need?” “I, uh, came into some money. Long story, and I really don’t want to get too much into the details … but I’m wondering if you’d be willing to run the bills through your counter for me? I’m not 100% sure they’re real, and I’d like a discreet way of verifying them. If they are, I’m going to pick up some bullion as well.” “Sure man. Happy to help. How much money are we talking about?”“$60,000” I flinch at that - I hate lying to friends, but at this point, I have no idea who to trust. Though if you want to be technical about it, I did come across $60,000. I am just simply not telling Kendrick about the other $940,000 that accompanied the $60k in the satchel that dropped into my life just three hours ago. “Come on by.” I pull apart a few $10,000 currency bands and start plucking random $100 bills from the middle of every 10k stack to assemble a randomized sample of the entire million. 100 bills, wrap it up. 100 bills, wrap it up. 100 bills, wrap it up. Three bands, thirty thousand dollars, randomized and fully assembled to be tested for authenticity. “Half” of my alleged $60k windfall. The rest of the loose bills are refolded back so there remains 97 stacks of $10k racks, re-wrapped and properly sorted. In 30 minutes, I will figure out if I’m rich, or holding on to enough illicit contraband to send me to Federal Prison for the rest of my life. =============================The Golden Path, like most bullion dealers, work out of small, highly secured office covered by multiple layers of security. At any given moment, Robert may have several hundred thousand dollars in cash or gold, silver and platinum bullion on the premise, it pays to be careful. One of the few civilians in California with a Concealed Carry Weapons permit, Kendrick and I met on pistol gun range ten years ago; we bonded over shooting .45 ACP slugs down-range. He and I spent countless hours debating the relative merits of his preference for single-action 1911s, vs my bias toward double-action SIG-Sauer P220s. In the bullion business, you learn to know the boundaries of money-laundering laws, and know how to walk right up to the edge without triggering reporting thresholds. Drop US$10,000 in cash or more at a car dealership, bank or bullion dealer in a single day’s transaction, and the U.S. authorities gets very interested in the source of your funds. By law, these business that receive such sums of cash must fill out invasive forms to tie the transaction to you and your Social Security Number. Keep cash transactions below US$10,000, and you can avoid much of that intense scrutiny. “Welcome back man. I haven’t seen you in a while.” A discreet man, Kendrick does not inquire further about the source of the cash. In the business of buying and selling gold bullion, you learn to comply with the letter of the law, while avoiding conversational topics that can jeopardize one’s own plausible deniability. While his clientele is mostly legitimate, I’m certain the most lucrative of his customers are criminals - and he smart enough to know not to ask the sort of questions that open up a line of liability for him.  So long as the proper theatrics of anti-money-laundering protocols are observed, everyone is technically in the clear. I hand him the three $10k stacks and he pulls the bands off them and puts the entire block in his high-speed currency counter. After a second, the machine spools up and the digital counter swiftly runs from zero to three hundred. Thirty thousand dollars. “It’s real.” It’s real. His words hang in the air for a moment, and it takes a moment for them to sink in. One million dollars. Genuine currency of the United States of America, the most recognized and accepted form of money in the world - denominated in crisp, non-sequential bills. I hold my face as neutral as possible, but my excitement made me slightly dizzy, and I am glad I was sitting down. “What’s the spot price of Gold today?” Kendrick’s eyes drift to his laptop computer, where the current day’s commodities prices were fed to him via a live stream. “$1334 Ask, $1335 Bid.” I nodded my understanding.Precious metals bullion trade in troy ounces, and prices are quoted on a per troy oz basis; depending on the specific type of bullion (bars, coins, make), there are different markups from the quoted price. Depending on the specific form, Gold is typically marked up by USD$20 to $60 over the day’s quoted Bid price, and sells for $5~10 over the Ask. “What do you have in inventory right now for gold?” “The usual. South African Kugerrands. American Eagles. Canadian Maples. Oh, I do have a lovely Credit Suisse 5oz bar that somebody just sold to me, and I’m happy to let it go for $25/oz over spot.” I quickly did the mental math calculation. With the hard-cap spending limit of $10,000 before I trigger any mandatory anti-money-laundering paperwork, $1335/oz works out to about seven troy ounces of bullion I can buy, without forcing Robert to fill out invasive forms about me and my identity. “I’ll take the 5oz Credit Suisse bar, and two American Gold Eagles.” Kendrick pulls out a calculator and taps in the numbers, “So five troy ounces at 25 over spot plus Eagles at $50 over spot works out to nine thousand six hundred and -“ “Take ten grand and keep the change.” I interrupt. “I will be back for more.” He raises his eyebrow, but says nothing. “Thank you. I’ll be right back.” He counts back $20,000 and hands it to me, taking the $10,000 in the back room of his office and returning with the 5oz Swiss bar and two heavy 1oz American Eagles, along with a receipt for US$9675. I pause for a moment and hand him back one of the $10,000 stacks. “I know the limit is $10k in transactions per day. Consider this pre-payment for a purchase tomorrow. Your call, on a mix of anything up that totals up to $9500. Keep the rest for you and Katie.” A barely-perceptible smile flickers across his face, then his face was clear again. “Sure thing.” There’s nothing like the feeling of holding physical gold - the density, color and heft of the metal is like no other substance on earth, and it is no wonder that since its discovery, every culture on Earth treated gold with awe and respect. With 18 hours left before I can understand my legal options, there’s only two things I know for certain: 1. The money is real. 2. At least one person knows exactly where I live, and where the money was dropped off. I need to get mobile. I need to get mobile and off the grid ASAP.... to be continuedIf you'd like to be the first to get updates to this story, please add me kai chang 張敦楷 (kaichang) on Twitter.

So you wanna learn how to become a copywriter my junior friend? Well it’s very possible. In fact, there’s really no formal education you need. Some of the top-paid copywriters in the world never went to college or took a writing class!No education!No formal training!!Make lots of money!!!…..now before you start getting crazy, let me step you back into the reality of becoming a copywriter:1.) What Is Copywriting?Copywriting is essentially moving words around to sell better.Let’s say I work for a company that has a webpage which gets 1 out of 500 visitors to buy something.If I was a copywriter, I would figure out how to make 1 out of 100 of those people buy. This means 5x more sales from the SAME webpage!A good copywriter will understand how to do this with their words, and also how to re-arrange pictures and buttons to get more sales.A good copywriter is not just a writer. They are a keen studier of the human psychology behind purchase decisions!2.) Understand why people hire copywriters:Think of the huge amount of content a lot of companies have to put out.A single insurance company will have to put out all this stuff:Ads on TVAds on the internetAds on radioBrochures for B2C salesBrochures for B2B salesBrochures for every different productForms to fill outForms to fill out for various different product linesGoogle adsFacebook adsUpdate their TwitterUpdate their Facebook pageMake content for their websiteMake the content for their website about each different productMake sure their content is convertingMake sure customers understand how to signupSend customers packets explaining their policyHave scripts for their sales people to followHave scripts for their customer support people to followWrite press releasesThe list goes on and on and on and on…Allllll of these things need to get written by or looked over by a copywriter. And that’s just a single example! Some companies will rely heavily on copywriters. Some companies (like 37Signals) require ALL members of the team to be great writers before they ever start.So people will pay a copywriter good money to handle these things for them. But YOU my young friend, need to understand that to get that money, you need to keep relationships within those companies that need those services.How to Get Clients As a Freelance Copywriter:This is by far the biggest question I get. And people seem to forget one thing:Establishing yourself as a freelance copywriter is the same as building a business from the ground up.You’ve got to put in LOTS of effort in the beginning, show talent, and not expect immediate riches. There’s no free lunches here boys and girls.A lot of people get entranced by the prospect of working from their laptop from anywhere in the world as copywriter. In fact people go nuts when I post pictures like this from various locations!Since all my copywriting business is conducted from a laptop, I can take off and go work from the beach.Or if I wanted to drum up an extra $10,000 really quick …..I can just devote some of my hours to copywriting gigs.But these luxuries are the result of hard work, actual results, and existing exposure.This won’t happen overnight for most copywriters. And probably NEVER will for a lot of them. However I’ll share some of the ways I’ve personally seen people get amazing (and high paid) copywriting gigs:METHOD #1.) Becoming popular on the web as a copywriter.If you become known as a famous copywriting figure, you will build instant credibility.And if you have high credibility, you can ask for more money.So how did I build credibility for my copywriting career?Building Copywriting Credibility Step 1.) Practicing what you psignNow:I originally ran a couple of businesses starting from high school, and I first applied some copywriting techniques to the email list I had.METHOD #2.) Becoming popular in a specific nicheSo a lot of lower-end copywriters will insist “I can write everything!” But in reality they should niche down when they start. For example, if you worked for a big health company and did a lot of writing for them, you should call yourself a copywriter that specializes in the health space.This will make it easier to gain credibility in a specific area.You probably wouldn’t super-trust the guy who mows your lawn for financial advice…..however you REALLY might take his advice on how to hedge bushes and get a clean line on the edge of a lawn.He has very specific advice, and lots of experience practicing what he’s talking about.Instead of being “just a copywriter” ….it would be better if you were “A female copywriter who specializes in talking to 1st time expecting mothers.”It would be best to hang out and network in places where people are selling stuff to 1st time expectant mothers. If someone need a copywriter, and you have experience in EXACTLY their niche…..guess who has a high chance of getting the gig??My personal niche started out with smaller companies and daily deals. Then moved into medium sized businesses.However if someone approached me to write for 1st time expectant mothers, I could DO It……but I don’t have experience and can’t exactly relate to the struggles of that demographic. So I try to stick to my area of expertise so I can deliver the maximum results.METHOD #3.) Becoming popular for big companiesTHIS method can apply to certain people, and be quite lucrative.Let’s say you worked for a big company in the marketing department and you were exposed to how a big marketing department tests & releases products.If you were to build a nice little network in the same industry, and then become a consultant with a VERY SPECIFIC expertise, then you get some other big companies to fork over A LOT of money.Smaller freelance gigs can pay a few hundred dollars. But a huge corporation who is a doing an 8+ month rollout of $100,000,000+ product will pay you some phat-ass cash to ensure they do it right.Now I personally probably couldn’t get one of these gigs because I’ve never worked inside a huge company. That means I lose major credibility because I’ve never walked the walk.But if you do have some very niche experience within a big corporation and had a few big wins, you might be able to become a very highly-sought-after consultant.The cool part is you only need a few good contacts for this.I know someone who wrote an oil-management program in the 70’s that’s still used today. Till this day he gets sweet-ass gigs from multiple companies JUST to be around if anyone needs help implementing it.Since the projects he consults for are $2billion+ …..the companies don’t mind shelling out major cash just to keep him around.Boring? Yes.Sweet cash flow? Yes.This is one of the benefits of working with a big company:You know how to implement projects within a large company. That is actually a rare skill.METHOD #4.) Get small-time gigs.Now there are some other ways to get copywriting gigs, but I’ve never seen anyone who consistently made big money doing these things alone, so I’ll just list them quickly:Posting on Fiverr for copywriting gigs.You’ll definitely get some leads this way, but your clients will usually be bargain-hunters and not HUGE jobs.Posting on Craigslist as a copywriter for hire. This will generally result in corporate copywriter jobs that are relatively low-paying ($35,000 – $45,000).Posting on UpWork as a copywriter for hire. This will get you small to medium gigs. It’s not my favorite wayMETHOD #5.) Post in Facebook Groups where people can use copywriting services.I think this one is the easiest. Just go to groups like The Cult of Copy Job Board that you are offering your services for a one-time low price of $xxxxx and that you’re for hire.A lot of times people will bite.People also constantly post gigs there such as:Not all the gigs will be good, but some will.In the beginning you will have to scrape together gigs, but if you start putting all your work inside a simple portfolio, you can gain some steam. Which brings me to :Make a Simple Copywriting Portfolio!Ok, listen to me carefully young buck:You DO NOT NEED a fancy website. In fact, I’ve never never ever seen someone get a copywriting gig directly from their portfolio. EVER!!The reason is: people are looking to hire you based on your skills at copywriting. Not “how fancy your website looks.” This is a common mistake. Look how crappy my copywriting consults page is. That page generates huge returns even though it sucks super bad. The desire to buy is created from previous exposure to me, NOT the way the page looks.People will spend months and lots of money and time on a fancy website, only to realize NO ONE IS COMING TO IT. The only people going there are the people they meet directly and tell to go there.The best type of copywriting portfolio is a simple page with the following elements:Your name.Your expertise (Social Media? Landing Pages? A/B Testing?).A few examples of your work.How they can book a session with you.I know it sounds counterintuitive, but some of the best copywriting pages I’ve EVER SEEN are super simple one’s like this:See how simple that is?It also only leaves them ONE option of what to do next, and that’s to book a session with you.These sessions should generally be a minimum of $100.If a client is not willing to pay at least $100 for a consultation session where you point out everything wrong with their page, they are NOT going to buy anyways.My minimum consultation session is $597 now. And I’ve learned the hard way that if people are not willing to pay it, they are not going to be willing to pay you more (or they just simply can’t afford it).Oddly enough, the more I charge for each hour session, the more respect and compliance I get from the client! They want to make SURE they get their money out of that session , so they ensure they show up on time and show up prepared.I would personally avoid doing free sessions. Because what generally happens is:1.) Everyone gets excited about working together.2.) You setup a meeting with this “prospective client”.3.) You prepare for the meeting and draw up a proposal.4.) You talk with the client and tell them what you’re going to do for them.5.) They tell you “let’s talk again soon after I run this by my boss.”6.) You never talk again…..and all that time was wasted.7.) You become sad and poor :-(To get people taking you seriously, you need to charge them for your time. If they decide to go for a full contract with you, then you can comp them the hour long session. However if they don’t go with you, at least you still get paid.Charging people for your time is a sure-fire way to get them to value your services.Every single successful freelance copywriter I know ALWAYS charges for their time.Some Copywriting Books for you to read:I’ve read a helluva lot of copywriting books, and these are the one’s I recommend you read to get off to a great start:BOOK 1.) Read The Gary Halbert Letters (Free) Start by reading “The Boron Letters”. Make sure you print each chapter out for maximum effect!Ch 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25You can also buy The Boron Letters directly from Amazon.BOOK 2.) If you want a book that sits on your desk and can re-cap this kourse quickly, then grab my book called “This Book Will Teach You How To Write Better” from Amazon.BOOK 3.) Read Advertising Secrets of the Written Word by Joseph Sugarman. This book usually costs in the $30 range, but is one of my go-to books for ideas on how to position copy. Almost every successful kopywriter will know this book.BOOK 4.) Also, check out Ogilvy on Advertising by David Ogilvy (great for traditional advertising advice as well)Your Next Steps To Becoming A Copywriter:I showed above in this post some good things to do first:Read the copywriting books I recommended above.Making a simple copywriting portfolio.Put yourself out there.Well my young friend, I hope this answers your question!-N

There’s a lot of misconceptions out there today, but after working online for the last few years…I can assure you, affiliate marketing has to be the most misunderstood subject there is.And don’t take that the wrong way either, I’m certainly not judging - as I went through the same thing myself…Where I started looking at all the ways I could make money online a few years back, and after coming across a blog post where this guru was bragging about how he made $1,000,000 from blogging…I couldn’t help but fall in love right away.Honestly hard not to, as they made it look so easy…Where all I had to do was write a few blog posts, optimize my SEO - share it on social media…And voila, I was a millionaire.Needless to say, I went all in after seeing this…And after writing a crazy amount of blogs, and posting even more useless stuff on Twitter…I finally checked my account 5 months later, and there it was…$17.That’s right, after working countless hours for 5 months straight - I’d made a whopping $17…And that was obviously depressing, but I wasn’t quite ready to give up yet - so after that…I ventured out and started looking around for a solution that’d help me fix this mess.Searched high and low, downloading every ebook I could find…Then finally, after doing this for a couple weeks - I came in contact with a guy who appeared to know what he was doing.Won’t bore you with the entire story now, as it’s not too important…But needless to say, after telling him about my troubles - and mentioning how I thought this whole affiliate marketing thing was going to be a little easier…He just laughed and mentioned something I’ll never forget:Yeah, because there’s one important concept nobody likes to talk about…No matter what you’re selling, whether it be an affiliate product or a $7 ebook…You always have to gain the trust of your reader before they’ll buy anything.In other words, nobody just sees some random tweet and buys an affiliate product because a stranger told them to…Or better yet, reads one blog post that’s clearly intended to make money...And that’s the same reason why it takes people months (if not years) before they make money off this.The reason for that is because they take the time to build up an audience, which is usually done with multiple blog posts…And that worked great back in the day, when SEO was new and everybody had a chance to claim their spot…But in today’s world, everybody and their dog is fighting for a higher ranking - meaning it not only takes longer to get one article on the front page, but takes years to get multiple articles on there…Which is what you really need to have enough traffic and build an audience.Anyway, after hearing this - I was pretty crushed…As I started to realize this might not be quite as easy as it seemed, but like a true mind reader…The guy told me not to worry after that, and mentioned how there’s actually a way to “hack” this process…It just takes a little more skill up front.Of course, I was all ears at this point…And after hearing him talk about everything for the next 30 minutes, I knew exactly what I needed to do next…Start creating marketing funnelsNow if you’re not familiar with this term already, it’s an overused concept where all these “digital marketers” have made it more complicated than it needs to be…But in the simplest terms, it’s really an automated system where you guide the reader through a journey - having multiple “conversations” with them along the way…Then at the end of the funnel, THAT’s when you offer your affiliate product.This works great for a lot of different reasons, like how you’re breaking down obstacles they have in regards to the end product - while also educating them along the way…But also because it gives you enough time to build trust with the reader (using automation).In other words, instead of being a random weirdo who’s posting on social media - thinking people are going to see your tweet and buy a product right away…You establish a relationship with them first, show how it can help them - THEN offer the product…And the entire process depends on how expensive your end product is, but on average - these funnels take around 5-7 days (for cold traffic, as you just send them to this system - then let it take care of the rest)...Which is a much better alternative to the 12 - 18 months everybody shoots for now.Needless to say, after learning about this concept - I went out and started purchasing expensive courses after that…And I’m not saying it happened on the first day, or the second day - or hell, the first month…But finally, after a lot of testing - and even more learning…I was able to start creating funnels that actually worked:And here’s the exact steps I used to do just that.Step #1 - Start with a product (or topic) you actually enjoyOne of the biggest problems I see with most affiliate marketers today, is how they chase the money…Not something they actually enjoy talking about.Don’t get me wrong either, I completely get it - as the main point of affiliate marketing is to make money…But here’s the thing, if you’re trying to sell something you don’t like - you’ll get burnt out right away…And with all the opportunity on ClickBank today, it’s really hard to NOT find a product that pays well - and you actually enjoy.At a bare minimum, I always tell people to pick a tool (or software) they’ve used before…But if none come to mind, then at least pick a topic you enjoy talking about.To give you an example of this, one of my favorite topics to talk about…Is copywriting, so if I didn’t have any tools that came to mind right away…I’d head over to Best Affiliate Programs | Top Premier Internet Retailer | Clickbank, and search for anything copywriting related.After doing this for a little while, I’d eventually come across a course from some copywriter who I actually like - so after that…I’d pick his product:And move onto the next step:Step #2 - Targeting the right audienceNow, over the years I’ve seen a lot of mistakes when it comes to digital marketing in general - especially affiliate marketing…But if there’s one common mistake that kills most dreams, it’s just not picking the right audience.This is dangerous for a lot of reasons, but the most obvious is well - if you don’t offer your product to the right person…Then they’re probably not going to buy it (be like selling tampons to young dudes).With that said, there’s always going to be multiple markets you can help as well - so the key here is just picking one and going with it…Which, going back to our current example…I’d pick a market of people who want to start making money online, but don’t know where to start.Like this market (for that product), as copywriting is really one skill that’ll help them succeed online…So that’d be the best place to start, then after we have that picked - it’s time to move onto:Step #3 - Build a system that turns cold traffic into hot leadsAlright, so as I’ve mentioned a few times - there’s a few major problems that prevent people from getting sales online…But one thing that’s always blown my mind, is how people think that just because customers are online - they don’t know how to think anymore.In other words, whenever we do “sales” offline - most people understand how important it is to show the benefits of your product to potential clients, and explain what it can do for them before ever making an offer…But then for some reason, once people go online - they think they can just build a landing page, put a “call-to-action” after that…And expect people to buy right away, which simply doesn’t work.Again, there’s a few reasons for this - but in the simplest terms, it’s usually because they just don’t understand what it is…So before you ever offer the sale, you always want to build an automated system that explains the benefits to your market - along with why they should buy the product you’re affiliated with.Going back to our current example…I’d know my market well enough to understand they probably don’t even know what copywriting is, so if I just told them to buy this affiliate product - they’d look at me like I’m an idiot…So to get around this mess, it’s my job to “meet them where they’re at”.In other words, since I know what their goal is (make money online) - it’s my job to show them how this skill can help them signNow that goal…And there’s a lot of different ways I can do this, but for the most part…I’ve always been a fan of email courses.These seem to work best as it’s information that’s dripped out over 5 days, so you’re not overwhelming them with everything at once…Then on top of this, it’s something they can read whenever they have time - so the “attendance” rates are usually a lot higher than every other method as well:Anyway, in this case I’d create an email course with the main logic of:“The one skill that’ll help you make money online”And there’s a lot of underlying psychology that goes on with email funnels, so it’s a little tougher than just writing 5 emails…But in the simplest terms, if you can give them an email course that explains how copywriting can help them signNow their goals…Then you will get some sales with that alone.Anyway, now that we have this in place - it’s time to move onto:Step #4 - Craft a landing page that converts like crazySo now that we have the email funnel created, it’s obviously important to have people enter that funnel…And the easiest way to do this, is with a high-converting landing page.I’ve tested a lot of different options over the years, from pop-ups to having a freebie on my homepage…And I can assure you, landing pages are hands down - the best way to go.The reason for this is because they only have one option when seeing a landing page, so that alone skyrockets conversions…But on top of this, it gives you a little more time to write “copy” that converts - so that’s extremely helpful as well.With that said, as with everything…There’s a lot of advanced tactics you could use, but if you want to see one of my landing pages that’s converting very well - then here you go:Alright, now that we have the email funnel in place - and a landing page that has people enter that email funnel…It’s time to move onto the last step:Step #5 - Driving traffic to that landing pageSo entrepreneurs are a different breed, and definitely come in different forms…But if there’s one common problem they all have, it’s always getting traffic.From SEO to posting on Pinterest, this is the one thing they all struggle with…And again, I went through this in the beginning stages of my journey as well - so I’m not poking fun…But over the years I’ve learned it’s really not that hard, you just have to understand how to meet your potential clients.There’s a lot of ways you can do this, including anything along the lines of:Facebook AdsTwitter AdsEtc…But for me personally, over the years - I’ve noticed it works best when I write a long-form blog…Then “boost” it in front of my audience.This works best as it starts the relationship off on the right foot, and as with everything - there’s a few ways to do this…But from my experience, it usually works best when you do this here on Quora - then “promote” your answer in front of the right audience.This works great as people on Quora are clearly there to read questions, so they want to see your answer (if it’s good)...And as with everything else - the pricing will vary by industry…But at the end of the day, this method is pretty cost-efficient all around…And to give you some context on this, here’s a recent campaign I ran:The only thing you want to remember with this, is that it needs to be something that leads people to your funnel, and you always need to have a call-to-action at the end (like this):So going back to our example, in this case - I’d go to Quora…Find any question that was something along the lines of:“How do I make money online?”Then after answering that question, at the end - I’d leave a call-to-action that says something along the lines of:“Want to learn one skill that’ll help you achieve this goal? If so, then click here to learn more”...And after that, the link would go to the landing page - so they could learn more about copywriting (if they wanted to) after that, and the rest of the process would take care of everything from there (on autopilot).Long story short…I’m sure we could really dig into the details if we wanted to, but after working in this industry for the last few years…If there’s one “secret” that separates people who make money on Clickbank, from those that don’t…It’s the concept of marketing funnels.The reason for this is because if you don’t have marketing funnels in place, then it’s impossible to establish a rapport with the reader - well, unless you get millions of visitors on your blog every month…But that takes too long, so not something I’d advise.On the other hand, when you put a system in place that guides the reader through a journey - and builds a rapport the entire time…THAT’s when the sales really start rolling in.At the end of the day, I guess it’s really like making a robotic version of yourself - where you put the sales process in place once, then let it work for you 24/7 after that…And if you’re a visual learner who wants to see the inside of one of these systems...Then check this out.

NOOOOOOO. You are talking to a military romance scammer. I received an email from the US Army that directly answers your question that is pasted below please keep reading.I believe you are the victim of a military Romance Scam whereas the person you are talking to is a foreign national posing as an American Soldier claiming to be stationed overseas on a peacekeeping mission. That's the key to the scam they always claim to be on a peacekeeping mission.Part of their scam is saying that they have no access to their money that their mission is highly dangerous.If your boyfriend girlfriend/future husband/wife is asking you to do the following or has exhibited this behavior, it is a most likely a scam:Moves to private messaging site immediately after meeting you on Facebook or SnapChat or Instagram or some dating or social media site. Often times they delete the site you met them on right after they asked you to move to a more private messaging siteProfesses love to you very quickly & seems to quote poems and song lyrics along with using their own sort of broken language, as they profess their love and devotion quickly. They also showed concern for your health and love for your family.Promises marriage as soon as he/she gets to state for leave that they asked you to pay for.They Requests money (wire transfers) and Amazon, iTune ,Verizon, etc gift cards, for medicine, religious practices, and leaves to come home, internet access, complete job assignments, help sick friend, get him out of trouble, or anything that sounds fishy.The military does provide all the soldier needs including food medical Care and transportation for leave. Trust me, I lived it, you are probably being scammed. I am just trying to show you examples that you are most likely being connned.Below is an email response I received after I sent an inquiry to the US government when I discovered I was scammed.

You arrive at lecture and sit perched on the edge of your seat, notebook open to a clean page and freshly-sharpened pencil in hand. You follow every word the professor says. Well, maybe you zone out a few times in the middle, but who doesn't? Besides, you're copying everything down and can review it later.That weekend, you diligently read the textbook. Maybe you skip a few parts since it's a busy week, but you definitely study the chapter summary and read all the examples. You do the homework problems, even starting three days early. When you're stuck, you go to office hours and ask the TA for help until they show you how to do it.Before the exam, you study your notes and the published homework solutions. You try the practice exam, and it seems the pieces are finally falling into place. You can solve most of the problems and remember most of the formulas and derivations! At last you take the final, referencing the single allowed sheet of notes you prepared at length the night before. You get almost every question right, or at least partial credit, and take home a well-deserved A.Three months later, you can hardly remember what the class was all about. What's going on? Why did you forget so much? Are you the only one? Should you have memorized more and worked even harder?The answer is no. A student who memorizes the entire physics curriculum is no more a physicist than one who memorizes the dictionary is a writer. Studying physics is about building skills, specifically the skills of modeling novel situations and solving difficult problems. The results in your textbook are just the raw material. You're a builder. Don't spend all your time collecting more materials. Collect a few, then build things. Here's how.The Cathedral and the StonesWhile delivering his famous set of freshman lectures on physics, Richard Feynman held a few special review sessions. In the first of these, he discussed the problem of trying to memorize all the physics you've learned:It will not do to memorize the formulas, and to say to yourself, "I know all the formulas; all I gotta do is figure out how to put 'em in the problem!"Now, you may succeed with this for a while, and the more you work on memorizing the formulas, the longer you'll go on with this method - but it doesn't work in the end.You might say, "I'm not gonna believe him, because I've always been successful: that's the way I've always done it; I'm always gonna do it that way."You are not always going to do it that way: you're going to flunk - not this year, not next year, but eventually, when you get your job, or something - you're going to lose along the line somewhere, because physics is an enormously extended thing: there are millions of formulas! It's impossible to remember all the formulas - it's impossible!And the great thing that you're ignoring, the powerful machine that you're not using, is this: suppose Figure 1 - 19 is a map of all the physics formulas, all the relations in physics. (It should have more than two dimensions, but let's suppose it's like that.)Now, suppose that something happened to your mind, that somehow all the material in some region was erased, and there was a little spot of missing goo in there. The relations of nature are so nice that it is possible, by logic, to "triangulate" from what is known to what's in the hole. (See Fig. 1-20.)And you can re-create the things that you've forgotten perpetually - if you don't forget too much, and if you know enough. In other words, there comes a time - which you haven't quite got to, yet - where you'll know so many things that as you forget them, you can reconstruct them from the pieces that you can still remember. It is therefore of first-rate importance that you know how to "triangulate" - that is, to know how to figure something out from what you already know. It is absolutely necessary. You might say, "Ah, I don't care; I'm a good memorizer! In fact, I took a course in memory!"That still doesn't work! Because the real utility of physicists - both to discover new laws of nature, and to develop new things in industry, and so on - is not to talk about what's already known, but to do something new - and so they triangulate out from the known things: they make a "triangulation" that no one has ever made before. (See Fig. 1-21.)In order to learn how to do that, you've got to forget the memorizing of formulas, and to try to learn to understand the interrelationships of nature. That's very much more difficult at the beginning, but it's the only successful way.Feynman's advice is a common theme in learning. Beginners want to memorize the details, while experts want to communicate a gestalt.Foreign language students talk about how many words they've memorized, but teachers see this as the most trivial component of fluency. Novice musicians try to get the notes and rhythms right, while experts want to find their own interpretation of the piece's aesthetic. Math students want to memorize theorems while mathematicians seek a way of thinking instead. History students see lists of dates and facts while professors see personality, context, and narrative. In each case, the beginner is too overwhelmed by details to see the whole. They look at a cathedral and see a pile of 100,000 stones.One particularly clear description of the difference between the experts' and beginners' minds comes from George Miller's 1956 study "The magical number seven, plus or minus two." Miller presented chess boards to both master-level chess players and to novices. He found that the masters could memorize an entire board in just five seconds, whereas the novices were hopeless, getting just a few pieces. However, this was only true when the participants were memorizing positions from real chess games. When Miller instead scattered the pieces at random, he found the masters' advantage disappeared. They, like the novices, could only remember a small portion of what they'd seen.The reason is that master-level chess players have "chunked" chess information. They no longer have to remember where each pawn is; they can instead remember where the weak point in the structure lies. Once they know that, the rest is inevitable and easily reconstructed.I played some chess in high school, never making it to a high level. At a tournament, I met a master who told me about how every square on the chess board was meaningful to him. Whereas, when writing down my move, I would have to count the rows and columns to figure out where I had put my knight ("A-B-C, 1-2-3-4, knight to C4") he would know instantaneously because the target square felt like C4, with all the attendant chess knowledge about control of the center or protection of the king that a knight on C4 entails.To see this same principle working in yourself right now, memorize the following. You have two seconds:首先放花生酱，然后果冻Easy, right? Well, it would be if you were literate in Chinese. Then you’d know it’s the important maxim, “first the peanut butter, then the jelly”.You can remember the equivalent English phrase no problem, but probably don't remember the Chinese characters at all (unless you know Chinese, of course). This is because you automatically process English to an extreme level. Your brain transforms the various loops and lines and spaces displayed on your screen into letters, then words, then a familiar sandwich-related maxim, all without any effort. It's only this highest-level abstraction that you remember. Using it, you could reproduce the detail of the phrase "first the peanut butter, then the jelly" fairly accurately, but you would likely forget something like whether I capitalized the first letter or whether the font had serifs.Remembering an equally-long list of randomly-chosen English words would be harder, a random list of letters harder still, and the seemingly-random characters of Chinese almost impossible without great effort. At each step, we lose more and more ability to abstract the raw data with our installed cognitive firmware, and this makes it harder and harder to extract meaning.That is why you have such a hard time memorizing equations and derivations from your physics classes. They aren't yet meaningful to you. They don't fit into a grand framework you've constructed. So after you turn in the final, they all start slipping away.Don't worry. Those details will become more memorable with time. In tutoring beginning students, I used to be surprised at how bad their memories were. We would work a problem in basic physics over the course of 20 minutes. The next time we met, I'd ask them about it as review. Personally, I could remember what the problem was, what the answer was, how to solve it, and even details such as the minor mistakes the student made along the way and the similar problems to which we'd compared it last week. Often, I found that the student remembered none of this - not even what the problem was asking! What had happened was, while I had been thinking about how this problem fit into their understanding of physics and wondering what their mistakes told me about which concepts they were still shaky on, they had been stressed out by what the sine of thirty degrees is and the difference between "centrifugal" and "centripetal".Imagine an athlete trying to play soccer, but just yesterday they learned about things like "running" and "kicking". They'd be so distracted by making sure they moved their legs in the right order that they'd have no concept of making a feint, much less things like how the movement pattern of their midfielder was opening a hole in the opponent's defense. The result is that the player does poorly and the coach gets frustrated.Much of a technical education works this way. You are trying to understand continuum mechanics when Newton's Laws are still not cemented in your mind, or quantum mechanics when you still haven't grasped linear algebra. Inevitably, you'll need to learn subjects more than once - the first time to grapple with the details, the second to see through to what's going on beyond.Once you start to see the big picture, you'll find the details become meaningful and you'll manipulate and remember them more easily. Randall Knight's Five Easy Lessons describes research on expert vs. novice problem solvers. Both groups were given the same physics problems and asked to narrate their thoughts aloud in stream-of-consciousness while they solved them (or failed to do so). Knight cites the following summary from Reif and Heller (1982)Observations by Larkin and Reif and ourselves indicate that experts rapidly redescribe the problems presented to them, often use qualitative arguments to plan solutions before elaborating them in greater mathematical detail, and make many decisions by first exploring their consequences. Furthermore, the underlying knowledge of such experts appears to be tightly structured in hierarchical fashion.By contrast, novice students commonly encounter difficulties because they fail to describe problems adequately. They usually do little prior planning or qualitative description. Instead of proceeding by successive refinements, they try to assemble solutions by stringing together miscellaneous mathematical formulas from their repertoire. Furthermore, their underlying knowledge consists largely of a loosely connected collection of such formulas.Experts see the cathedral first, then the stones. Novices grab desperately at every stone in sight and hope one of them is worth at least partial credit.In another experiment, subjects were given a bunch of physics problems and asked to invent categories for the problems, then put the problems in whatever category they belonged. Knight writes:Experts sort the problems into relatively few categories, such as "Problems that can be solved by using Newton's second law" or "Problems that can be solved using conservation of energy." Novices, on the other hand, make a much larger number of categories, such as "inclined plane problems" and "pulley problems" and "collision problems." That is, novices see primarily surface features of a problem, not the underlying physical principles.The "Aha!" FeelingIt is clear that your job as a student is to slowly build up the mental structures that experts have. As you do, details will get easier. Eventually, many details will become effortless. But how do you get there?In the Mathoverflow question I linked about memorizing theorems, Timothy Gowers wroteAs far as possible, you should turn yourself into the kind of person who does not have to remember the theorem in question. To get to that stage, the best way I know is simply to attempt to prove the theorem yourself. If you've tried sufficiently hard at that and got stuck, then have a quick look at the proof -- just enough to find out what the point is that you are missing. That should give you an Aha! feeling that will make the step far easier to remember in the future than if you had just passively read it.Feynman approached the same questionThe problem of how to deduce new things from old, and how to solve problems, is really very difficult to teach, and I don't really know how to do it. I don't know how to tell you something that will transform you from a person who can't analyze new situations or solve problems, to a person who can. In the case of the mathematics, I can transform you from somebody who can't differentiate to somebody who can, by giving you all the rules. But in the case of the physics, I can't transform you from somebody who can't to somebody who can, so I don't know what to do.Because I intuitively understand what's going on physically, I find it difficult to communicate: I can only do it by showing you examples. Therefore, the rest of this lecture, as well as the next one, will consist of doing a whole lot of little examples - of applications, of phenomena in the physical world or in the industrial world, of applications of physics in different places - to show you how what you already know will permit you to understand or to analyze what's going on. Only from examples will you be able to catch on.This sounds horribly inefficient to me. Feynman and Gowers both signNowed the highest level of achievement in their domains, and both are renowned as superb communicators. Despite this, neither has any better advice than "do it a lot and eventually expertise will just sort of happen." Mathematicians and physicists talk about the qualities of "mathematical maturity" and "physical insight". They're essential to moving past the most basic level, but it seems that no one knows quite where they come from.Circular ReasoningThere are certainly attempts to be more systematic than Feynman or Gowers, but before we get to that, let's take a case study. I recall that as a college freshman, I knew that the formula for the acceleration of a ball orbiting in a circle was [math]a = v^2/r[/math]. I wanted to know why, so I drew a picture:I imagined a small ball starting on the right side of the circle, heading upwards where the blue velocity vector [math]v_1[/math] is drawn. The ball moves around the circle, goes counter-clockwise over the top and then heads downwards on the left hand side, where the red velocity [math]v_2[/math] is. The ball's velocity changed, which means it accelerated. The acceleration is[math]a = \frac{\Delta v}{\Delta t}[/math][math]\Delta v[/math] is clearly [math]2v[/math], and [math]\Delta t[/math] is the time it takes to go half way around the circle, which is [math]\frac{\text{distance}}{\text{speed}} = \frac{\pi r}{v}[/math]. Hence, the acceleration is[math]a = \frac{2v}{\pi r/v} = \frac{2 v^2}{\pi r} \approx 0.64 \frac{v^2}{r}[/math]This isn't quite right. The answer is supposed to be [math]v^2/r[/math]. Somehow there is an extra factor of [math]2/\pi[/math] floating around.If you already understand calculus, this is a silly and obvious mistake. But for me it took quite some time - weeks, I think - until I understood that I had found the average acceleration, but the formula I was trying to derive was the instantaneous acceleration.The way I broke out of this mental rut was to think about the case where the ball has gone one quarter of the way around, like this:Then the same approach gives[math] a = \frac{\Delta v}{\Delta t} = \frac{2\sqrt{2}v^2}{\pi r} \approx 0.90 \frac{v^2}{r}[/math],which is closer to the right value. If you try it when the ball goes 1/8 the way around, you get[math]a = \frac{4 \sqrt{2 - \sqrt{2}}v^2}{\pi r} \approx 0.97 \frac{v^2}{r}[/math]and you're getting the idea that what you have to do is take the limit as the ball goes an infinitesimal fraction of the way around. (By the way, if I had been clever, maybe I'd have discovered Viète's formula this way, or something like it. I only recognized this now because I remembered encountering Viete's formula. So memory certainly has its place in allowing you to make connections. It's just not as central as beginners typically believe.)How do you do that "infinitesimal fraction of the way around" thing? Well, if the ball travels an angle [math]\theta[/math] around the circle, we can draw the before and after velocities asand[math] \Delta v = 2 \sin (\theta/2) v[/math]which in the limit [math]\theta \to 0[/math] becomes[math] \Delta v = \theta v[/math]and[math] a = \frac{\Delta v}{\Delta t} = \frac{\theta v}{\theta r/v} = \frac{v^2}{r}[/math]But all of this took a long time to come together in my mind, assembling gradually, but in discrete chunks with each small epiphany. As I walk through it now, I can see there are many concepts involved, and in fact if you're a beginning student it's likely that the argument isn't clear because I skipped some steps.The main idea in that argument is calculus - we're looking at an infinitesimal displacement of the ball. To understand the entire argument, though, we also need to do a fair amount of geometry, develop the idea of sliding velocity vectors around in space so they originate at the same point, introduce the concept of an arbitrary angle of rotation [math]\theta[/math], find the time it takes to rotate by that angle for a given [math]r[/math] and [math]v[/math], use the small-angle approximation of the sine function, and maybe a couple other things I'm not seeing.That's a lot of mental exercise. It's no wonder that working all this out for yourself is both harder and more effective than reading it in the book. Just reading it, you'll skip over or fail to appreciate how much goes into the derivation. The next time you try to understand something, you want those previously-mastered ideas about geometry and calculus already there in your mind, ready to be called up. They won't be if you let a book do all the work.Today, I can solve this problem in other ways. For example, I could write down the rectangular coordinates and differentiate, describe the motion in the complex plane as [math]r e^{i\omega t}[/math] and differentiate that, or transform to a rotating reference frame and note the centrifugal force on the stationary ball and conclude it must be accelerating in an inertial frame. A cute one is to write down the position and velocity vectors by intuition, and notice that going from position to velocity you rotate 90 degrees and multiply the length by [math]v/r[/math]. To go from velocity to acceleration is mathematically identical, so rotating another 90 degrees and multiply by [math]v/r[/math] again we obtain the answer.I can argue from dimensional analysis that the only way to get something with units of acceleration is [math]v^2/r[/math], or heuristically point out that if you increase the velocity, the velocity vectors get bigger, but we also go from one to the next in less time, so the acceleration ought to scale with [math]v^2[/math], etc.I also see aspects of the problem that I didn't back then, such as that this isn't really a physics problem. There are no physical laws involved. It would become a physics problem if we included that the ball is circling due to gravitational forces and used Newton's gravitational law, for example, but as it stands this problem is just a little math.So yes, I can easily memorize this result and provide a derivation for it. I can do that for most of the undergrad physics curriculum, including the pendulum and Doppler formulas you mentioned, and I think I could ace, or at least beat the class average, on the final in any undergraduate physics course at my university without extra preparation. But I can do that because I built up a general understanding of physics, not because I remember huge lists of equations and techniques.How to Chunk ItI can do these things now because of years' of accumulated experience. Somehow, my mind built chunks for thinking about elementary physics the same way chess players do for chess. I've taught classes, worked advanced problems, listened to people, discussed with people, tutored, written about physics on the internet, etc. It's a hodgepodge of activities and approaches, and there's no way for me to tease from my own experience what was most important to the learning process. Fortunately, people from various fields have made contributions to understanding how we create the cognitive machinery of expertise. Here is a quick hit list.George Pólya's How to Solve It examines the problem-solving process as a series of stages, and suggests the student ask themselves specific questions like, "Is it clear that there enough information to solve the problem?"Scott H Young, Cal Newport, and many others give specific advice on study skills: how to take notes, how to diagram out the connections between ideas, how to test your knowledge, how to fit what you're learning into the larger scheme of things, etc.When you do need to memorize things, spaced repetition software like Anki takes an algorithmic, research-backed approach to helping you remember facts with the minimum of time and effort.K. Anders Ericsson has tried to find the key factors that make some forms of practice better than others - things like getting feedback as you go and having clear goals. He refined these into the concept of Deliberate Practice. He also believes there is no shortcut. Even if you practice effectively, it usually takes around 10,000 hours of hard work to signNow the highest levels in complex fields like physics or music.Chunking and assigning meaning are your mind's ways of dealing with the information overload of the minutiae that inevitably pop up in any field. Another approach, though, is to try to expand your mind's ability to handle those minutiae. If you can push your "magical number" from seven to ten, you'll be able to remember and understand more of your physics work because it takes a bit longer to fill your cognitive buffer. Dual N-Back exercises are the most popular method of working on this. Nootropic drugs may also provide benefits to some people. Low-hanging fruit first, though. If you aren't sleeping 8-9 hours a day, getting a few hours of exercise a week, and eating healthy food for most meals, you're probably giving up some of your mind's potential power already. (There is individual variation, though.)Howard Gardner is one champion of the idea of multiple intelligences, or different learning types. When working on electric fields, for example, Gardner might advise you to study Maxwell's equations, draw pictures of vector fields and intuit their curls, get up and use your body, pointing your arms around to indicate electric field vectors, write or speak about what you're studying, learn with a friend or tutor, or maybe even create musical mnemonics to help you study, depending on where your personal strengths lie. Certainly, all students should build facility with drawing sketches, plotting functions, manipulating equations, visualizing dynamics, and writing and speaking about the material.Psychologist Carol Dweck's research studies the effect of your attitude towards learning on how much you learn, finding, for example, that children praised for their hard work are likely to press on further and learn more when given tough problems, whereas children praised for their intelligence are more likely to give up.Productivity guru David Allen helps people organize their lives and defeat procrastination with specific techniques, such as dividing complicated tasks into small, specific "next actions" and deciding when to do them, then organizing them in a planner system.Mihály Csíkszentmihályi believes that people operate best in a state of "flow", where they are so focused on the task they find it enjoyable and engrossing to the point they're innately motivated to continue. He emphasizes, for example, that the task needs to be the right level of difficulty - not too hard and not too easy - to find the flow state. (Some people think this state doesn't jibe with deliberate practice; others contend it's possible to achieve both simultaneously.)Taken together, this yields enough practical advice to chew on for months or years. To summarize, when you are learning something new:Try to figure it out for yourselfIf you get stuck, take a peek at your textbook to get the main ideaTeach the idea to someone elseOnce you've learned something, repeat the entire reasoning behind it for yourself, working through each detailAsk yourself Pólya's questions when you're stuckUse Young and Newport's techniques to map out the ideas of your class and relate them to your prior knowledgeMake Anki decks and review them a few minutes a day to retain what you've learnedMake sure your study sessions include all the principles of deliberate practice, especially feedback, challenge, and attentionBuild an image of yourself as someone motivated by learning and proud of having worked hard and effectively rather than as someone proud of being smart or renowned.Find a organizational system that lets you handle all the details of life smoothly and efficiently.Search for the flow state, notice when you enter it, and put yourself in position to find flow more and more often.Work on different subjects, reviewing both advanced and basic material. They will eventually all form together in your mind, and you're likely to have to take at least two passes at any subject before you understand it well.Take care of your physical health.This list does not include reading every page of the textbook or solving every problem at the end of the chapter. Those things aren't necessarily bad, but they can easily become rote. Building the material up for yourself while dipping into reference materials for hints is likely to be more effective and more engaging, once you learn to do it. It is a slow, difficult process. It can be frustrating, sitting there wracking your brain and feeling incredibly stupid for not understanding something you know you're supposed to have down. And strangely, once you have it figured out, it will probably seem completely obvious! That's your reward. Once the thing is obvious, you've chunked it, and you can move on. (Though you still need to review with spaced repetition.) This is the opposite of the usual pattern of sitting in lectures and feeling you understand everything quite clearly, only to find it all evaporated the next day, or acing a final only to find your knowledge is all gone the next month.That, I believe, summarizes the practical knowledge and advice about the learning process. Memorizing equations and derivations is difficult and ineffective because they are just the details. You can only handle a few details before your mind gets swamped. To cope, train yourself to the point where you process equations and physical reasoning automatically. This will free your conscious effort up to take in the big picture and see what the subject is all about.It Just Gets In The Way, You SeeSomehow, I've developed a "this is calculus" instinct, so that if I see the problem about acceleration in circular motion, or any other problem about rates of change, I know that it's talking about a limit of some kind. Where does this instinct exist in my brain? What form does it take? How does it get called up at the right time?George Lakoff believes that almost everything we understand is via metaphor. Any sort of abstract concept is understood by linking it to concrete concepts we've previously understood. For example, in Where Mathematics Comes From, Lakoff and coauthor Rafael Nuñez argue that we think of the mathematical concept of a "set" as a sort of box or container with things stacked in it. We reason about sets using our intuition about boxes, then later go back and support our conclusions with the technical details. Learning to reason about sets, then, is learning to think about the box metaphor and translate it back and forth into the formal language of axioms and theorems. This seems to fit with the introspective reports of many mathematicians, who say they build intuitive or visual models of their mathematics when finding results, then add in the deltas and epsilons at the end.This may be why we so often see beginning students asking things like, "but what is the electron, really?" If they were told it is just a tiny little ball, that would work, because it's a very easy metaphor. But instead, they're told it's not a ball, not a particle, not a wave, not spinning even though it has spin, etc. In fact, they're told to dismiss all prior concepts entirely! This is something Lakoff believes is simply impossible. No wonder students are bobbing in an ocean of confused thought bubbles, with nothing but mixed metaphors to grasp at until the last straw evaporates, across the board.Linguists like Steven Pinker believe that the language we use tells us how our mind works. Physicists certainly do have a specialized lexicon, and the ability to use it correctly correlates pretty well to general physics intuition, in my experience. In his review of Pinker's The Stuff of Thought, Douglas Hofstadter summarizes:Pinker shows, for example, how subtle features of English verbs reveal hidden operations of the human mind. Consider such contrasting sentences as "The farmer loaded hay into the wagon" and "The farmer loaded the wagon with hay." In this pair, the verb "load" has two different kinds of objects: the stuff that gets moved and the place it goes. Also, in the first sentence, the destination is the object of one preposition; in the second, the stuff is the object of another. Pinker sees these "alternations" as constituting a "microclass" of verbs acting this way, such as "spray" ("spray water on the roses" versus "spray the roses with water"). Where does this observation lead him? To the idea that we sometimes frame events in terms of motion in physical space (moving hay; moving water) and sometimes in terms of motion in state-space (wagon becoming full; roses becoming wet).Moreover, there are verbs that refuse such alternations: for instance, "pour." We can say "I poured water into the glass" but not "I poured the glass with water." What accounts for this curious difference between "load" and "pour"? Pinker claims that pouring merely lets a liquid move under gravity's influence, whereas loading is motion determined by the human agent. "Pour" and "load" thus belong to different microclasses, and these microclasses reveal how we construe events. "[W]e have discovered a new layer of concepts that the mind uses to organize mundane experience: concepts about substance, space, time, and force," Pinker writes. " . . . [S]ome philosophers consider [these concepts] to be the very scaffolding that organizes mental life. . . . But we've stumbled upon these great categories of cognition . . . by trying to make sense of a small phenomenon in language acquisition."If correct, then in order to think about physics the way an expert does, we should learn to speak the way experts do. If we try to solve physics problems using the words "load" and "pour", we may be carrying around a bunch of distracting anthropocentric baggage. If we don't recognize that, we'll get stuck, saying the problem "doesn't make sense", when really it's our linguistically-instilled expectations that are wrong. To combat this, it may be just as helpful to gain facility with the language of physics as with its equations.Five Easy Lessons provides a clear example of such difficulties: the case study of "force". As I type this, my laptop is sitting on a desk which exerts an upward force on it. Few beginning students believe this is really a force, even after they've been browbeaten into drawing arrows for the "normal force" on exam diagrams.The problem is in the way we use "force":"The robber forced the door open." "Your apology sounded forced.""...the force of the explosion..." "...the force of righteousness...""I'm being forced to take physics even though I'll never use it."Literally or figuratively, we think of "force" as implying not only motion, but intent or purpose, and also control. Force is for people pushing on things, or maybe for cars and projectiles. These things are using energy and will run down if left alone. But the desk under my laptop? It's just sitting there, totally passive. How could it be "exerting a force" when it doesn't even get tired? Needing some sort of rationalization for why the laptop doesn't fall, beginners say that it's not that the desk exerts a force on the laptop, the desk just provides something for the laptop to sit on. Or if something falls on the desk, the desk didn't exert a force to stop it. It just got in the way is all. Why doesn't the professor understand this obvious difference? A desk exerting a force? Come on...Five Easy Lessons describes how students only overcome this difficulty after seeing a classroom demonstration where, using a laser pointer and a mirror laid on the desk top, the professor demonstrates how when a heavy cinder block is laid on the desk, the surface responds by bending out of its natural shape, exerting force on the cinder block like a compressed spring would.You may need to find many such visualizations before you can reconcile your colloquial use of words with their use in physics. But this might also be dangerous, because although finding a way to make physics obey your idea about what a word means works decently in this case, in other instances it's your expectations for the word that ought to change. (Relativity, with words like "contraction", "slowing down", etc. is a good example.)Mythologist Joseph Campbell believes that we understand the world primarily through story. Perhaps we understand derivations, experimental evidence, and the logic behind physical conclusions as a sort of story, and it's in building this story that our cognitive chunks are formed.Mind The Neural Gap JunctionsYou are the pattern of neural activity in your brain. When a part of you changes, building a new memory, installing a new habit, or constructing a tool to approach a class of problems, that change must be reflected somewhere in your brain.Lesswrong user kalla724 describes this process in "Attention control is critical for changing/increasing/altering motivation"First thing to keep in mind is the plasticity of cortical maps. In essence, particular functional areas of our brain can expand or shrink based on how often (and how intensely) they are used. A small amount of this growth is physical, as new axons grow, expanding the white matter; most of it happens by repurposing any less-used circuitry in the vicinity of the active area. For example, our sense of sight is processed by our visual cortex, which turns signals from our eyes into lines, shapes, colors and movement. In blind people, however, this part of the brain becomes invaded by other senses, and begins to process sensations like touch and hearing, such that they become signNowly more sensitive than in sighted people. Similarly, in deaf people, auditory cortex (part of the brain that processes sounds) becomes adapted to process visual information and gather language clues by sight.But, they caution, these neural changes occur primarily to those parts of our minds to which we pay conscious attention:A man is sitting in his living room, in front of a chessboard. Classical music plays in the background. The man is focused, thinking about the next move, about his chess strategy, and about the future possibilities of the game. His neural networks are optimizing, making him a better chess player.A man is sitting in his living room, in front of a chessboard. Classical music plays in the background. The man is focused, thinking about the music he hears, listening to the chords and anticipating the sounds still to come. His neural networks are optimizing, making him better at understanding music and hearing subtleties within a melody.A man is sitting in his living room, in front of a chessboard. Classical music plays in the background. The man is focused, gritting his teeth as another flash of pain comes from his bad back. His neural networks are optimizing, making the pain more intense, easier to feel, harder to ignore.You need to pay attention not just to doing physics, but to the right parts of doing physics - the parts most related to intuition.James Nearing gave his advice on how to do this in Mathematical Tools for PhysicistsHow do you learn intuition?When you've finished a problem and your answer agrees with the back of the book or with your friends or even a teacher, you're not done. The way do get an intuitive understanding of the mathematics and of the physics is to analyze your solution thoroughly. Does it make sense? There are almost always several parameters that enter the problem, so what happens to your solution when you push these parameters to their limits? In a mechanics problem, what if one mass is much larger than another? Does your solution do the right thing? In electromagnetism, if you make a couple of parameters equal to each other does it reduce everything to a simple, special case? When you're doing a surface integral should the answer be positive or negative and does your answer agree?When you address these questions to every problem you ever solve, you do several things. First, you'll find your own mistakes before someone else does. Second, you acquire an intuition about how the equations ought to behave and how the world that they describe ought to behave. Third, It makes all your later efforts easier because you will then have some clue about why the equations work the way they do. It reifies the algebra.Does it take extra time? Of course. It will however be some of the most valuable extra time you can spend.Is it only the students in my classes, or is it a widespread phenomenon that no one is willing to sketch a graph? (\Pulling teeth" is the cliche that comes to mind.) Maybe you've never been taught that there are a few basic methods that work, so look at section 1.8. And keep referring to it. This is one of those basic tools that is far more important than you've ever been told. It is astounding how many problems become simpler after you've sketched a graph. Also, until you've sketched some graphsof functions you really don't know how they behave.(To see the advice on graphs, along with a detailed step-by-step example, see his book, free online)Brown Big SpidersOne of the difficulties with chunks is that they're mostly subconscious. We may ultimately know of their existence, as did the chess master who told me he knew how each square of the chess board felt, but their precise nature and the process of their creation are almost immune to introspection. The study methods I've talked about above are empirically useful in creating chunks, so we have guidelines for how to make new chunks in general, but we usually don't know which ones we are creating.Lesswrong user Yvain comments on the essay Being a teacherI used to teach English as a second language. It was a mind trip.I remember one of my students saying something like "I saw a brown big spider". I responded "No, it should be 'big brown spider'". He asked why. Not only did I not know the rule involved, I had never even imagined that anyone would ever say it the other way until that moment.Such experiences were pretty much daily occurrences.In other words, the chunkiest cognitive process we have - language - develops largely without our awareness. (In retelling this story, I've met a surprising number of people who actually did know about adjective order in English, but most of them either learned English as a second language or had studied it in psychology or linguistics course.)This makes it incredibly difficult for physics teachers or textbook writers to communicate with beginners. It's inevitable that beginners will say that a certain lecturer or book just doesn't explain it clearly enough, or needs to give more examples. Meanwhile, the lecturer has no idea why what they said wasn't already perfectly clear and thinks the example was completely explicit. Neither party can articulate the problem, the student because they can't see the incorrect assumption they're making, the professor because they don't realize they've already made such an assumption.For example, once I was proctoring a test in a physics class for biology majors. A question on the test described a certain situation with light going through a prism and asked, "What is the sign of the phase shift?" A student came up to ask for clarification, and it wasn't until they'd asked their question three times that I finally got it. They thought they were supposed to find the "sign" as in a signpost, or marker. There would be some sort of observable behavior that would indicate that a phase shift had occurred, and that was the "sign of the phase shift." Until then, I was only able to think of "sign" as meaning positive or negative - did the wave get advanced or retarded?If you want to learn a language with all those rules you don't even know about, you need to immerse yourself. Endless drills and exercises from a book won't be enough, as millions of Americans a decade out of high school straining to remember, "Dondé esta el baño?" can attest. You need to read, speak, see, and hear that language all around you before it takes.To learn physics, then, read, speak, and hear it all around you. Attend colloquia. Read papers. Solve problems. Read books. Talk to professors and TA's, and expose yourself to all the patterns of thought that are the native language of the field.As you learn, you will build the right chunks to think about physics without realizing what they are. But there's a flip side to this problem, which is that when you're not doing physics, you can build the wrong chunks. They can get in the way, and again you don't realize it.In Drawing on the Right Side of the Brain, Betty Edwards discusses an exercise she gave her art students:One day, on impulse, I asked the students to copy a Picasso drawing upside down. That small experiment, more than anything else I had tried, showed that something very different is going on during the act of drawing. To my surprise, and to the students' surprise, the finished drawings were so extremely well done that I asked the class, "How come you can draw upside down when you can't draw right-side up?" The students responded, "Upside down, we didn't know what we were drawing."When we see a recognizable image, unconscious chunking immediately gets to work, interpreting, imparting meaning, and inevitably distorting. Learning to draw, according to Edwards, involves circumventing harmful chunks as much as building helpful ones.So it is with physics. The ideas about force, animation, and intent discussed in the laptop-and-desk example seem to illustrate just this problem. Five Easy Lessons lists many of the known misconceptions that students have somehow taught themselves in each topic of introductory physics - for example that electric current gets used up as it goes around a circuit. But I think it's likely that there are many more such obstructive thought patterns that we don't yet know exist. These might be more general notions about such things as cause and effect, what nature "wants" to accomplish, etc.I Feel DumbEducators are perpetually frustrated by what seems like an outrageous pattern. They explain something clearly. The students all claim to understand perfectly, and can even solve quantitative problems. Still, when you ask the students to answer basic conceptual questions, they get it all wrong. How is this possible?In this YouTube video, Veritasium explores what happens when you explain something clearly:Amazingly, the clearer the explanation, the less students learn. Humans have a huge array of cognitive biases. In general, these various biases work so that we'll keep believing whatever it was we believed to begin with, unless there's a really good reason not to. Someone giving a clear, authoritative physics lecture does not register in your mind as a good reason to check your beliefs, so you listen happily and rave about what a great lecture it was, all while maintaining your wrong ideas.However, with the right stimulus you can get your brain to throw out the old, wrong ideas. Entering such a state is a prerequisite to true learning, and fortunately we can detect it in ourselves. We call it confusion.Confusion is a message from your emotional mind (the part that tells your analytical mind what decisions to start justifying). It's saying, "Hey, something about our beliefs is very wrong, and this is actually important. Pay attention and figure it out."A great lecturer, instead of being clear, will confuse students by asking them to predict ahead of time what a demonstration will show, then do it, and the opposite actually occurs. Or they will ask students to solve questions that sound straightforward, but in fact the students can't figure out. Only after confusion sets in will the teacher reveal the trick.You want to defeat your biases, toss out your wrong beliefs, and learn physics to the Feynman level - the level where you create the knowledge as you go along. Even many specialists never fully get there, instead rising to increasingly-sophisticated levels of rehashing the same memorized arguments in a way that can carry them quite far and trick most people. The only way to avoid this is to spend many, many hours thoroughly confused.Have you ever lost an argument, only to think of the perfect retort two days later when stopped at a traffic light? This shows how your mind will continue working on hard problems in the background. It eventually comes up with a great answer, but only if you first prime it with what to chew on. This works for physics problems just as well as for clever comebacks, once you find good problems to grapple with. I conjecture that engaging this subconscious system requires a strong emotional connection to the problem, such as the frustration or embarrassment of being dumbstruck in an argument or the confusion of being stumped by a hard problem.Confusion is essential, but often also unpleasant. When you repeatedly feel frustrated or upset by your confusion, your mind unconsciously learns to shy away from hard thinking. You develop an ugh field.This could happen for different reasons. A common one arises in people who judge themselves by their intellect. Confusion for such people is a harsh reminder of just how limited they are; it's a challenge to their very identity. Whether for this reason or some other, it's common for students and academics to fall into patterns of procrastination and impostor syndrome when navigating the maze of confusion that come with their chosen path.I don't have the answer for this. I have heard many people tell their stories, but I have yet to figure out my own. Sometimes confusion feels awful, and my story in physics is a jerky, convoluted one because of how I've dealt with that. But once in a while a problem is so good that none of that matters. When I find one of these problems, it hijacks my mind like Cordyceps in a bullet ant, jerking me back to a fresh piece of scratch paper again and again, sometimes for days. If you signNow this state over and over, you'll know Feynman meant by, "What I cannot create I do not understand"Get confused. Solve problems. Repeat. The universe is waiting for you.ReferencesIn order of appearance in this answerFeynman's Tips on Physics: Richard P. Feynman, Michael A.

Anders Ericsson studying deliberate practice, in fact there are thousands of people working in those fields. The ones I've mentioned are simply the most public figures or those I've come across by chance. I haven't even read the original research in most of these cases, relying on summaries instead.The answer is also preliminary and incomplete. There's lots of research left to be done, and I'm not an expert in what's out there. Still, here is a guide to some further resources that have informed this answer.For an overview of the psychology of learning, I like Monisha Pasupathi's audio course How We Learn from The Teaching Company. It covers many clever experiments designed to help you build a model of what happens in your mind as you learn.Bret Victor explores software solutions to visualizing the connection between physical world, mathematical representation, and mental models. Check outThe Ladder of AbstractionExplorable ExplanationsI think it's helpful to build an innate impression of your mind as not perceiving the world directly, but as concocting its own, tailored interpretation from sense data. All your consciousness ever gets to experience is the highly-censored version. The books of Oliver Sacks are great for making this clear by illustrating what happens with people for whom some of the processing machinery breaks down.The LessWrong Sequences were, for me, a powerful introduction to the quirks of human thought, preliminary steps towards how to work best with the firmware we've got, and what it means to seek truth.Selected BibliographyThese are some physics books to which have helped me so far. I'm not choosing them for clear exposition or specialty knowledge in a certain subject, but for how I think they helped me understand the way to think about physics generally.Blandford and Thorne, Applications of Classical PhysicsEpstein, Thinking PhysicsFeynman, Lectures on Physics------------ The Character of Physical Law------------ QED: The Strange Theory of Light and Matter------------ Tips on PhysicsGeroch, General Relativity from A to BLevi, The Mathematical MechanicLewin, Walter "Classical Mechanics", "Electricity and Magnetism" (video lectures with demonstrations on MIT OpenCourseWare)Mahajan, Street-Fighting MathematicsMorin, Introduction to Classical MechanicsNearing, Mathematical Tools for PhysicsPurcell, Electricity and Magnetism----------, Back of the Envelope ProblemsSchey, Div, Grad, Curl, and All ThatThomas and Raine, Physics to a DegreeThompson, Thinking Like a PhysicistWeisskopf, "The Search for Simplicity" (articles in Am.

I was selected for a summer internship 2016.I tried to be very open while filling the preference form: I choose many products as my favorite products and I said I'm open about the team I want to join.I even was very open in the  location and start date to get host matching interviews (I negotiated the start date in the interview until both me and my host were happy.) You could ask your recruiter to review your form (there are very cool and could help you a lot since they have a bigger experience).Do a search on the potential team.Before the interviews,  try to find smart question that you are going to ask for the potential host (do a search on the team  to find nice and deep questions to impress your host). Prepare well your resume.You are very likely not going to get algorithm/data structure questions like in the first round. It's going to be just some friendly chat if you are lucky. If your potential team is working on something like machine learning, expect that  they are going to ask you questions about machine learning, courses related to machine learning you have and relevant experience (projects, internship). Of course you have to study that before the interview. Take as long time as you need if you feel rusty. It takes some time to get ready for the host matching (it's less than the technical interview)  but it's worth it of course.

My Jee Mains score was 196. My AIR was something around 10200.For joining da-iict you can do it in two following ways :You can fill form of ACPC - Gujarat if you belong or living in Gujarat. You will surely get in da-iict if your merit rank is less than 250. Even if its above 250, you can still join any other college and apply again in the round of counselling which are held for seats which are not filled in earlier rounds of counselling. The cut off for this round generally goes to 400 merit rank. If you are from Gujarat board, there are more chances of you getting a nice ACPC merit rank.Another method is through all India rank of Jee Mains. You need to fill out an online form before a specific date and wait for the merit list to be declared. You will get admission if your rank is under 15000 AIR.I took admission from ALL India quota since my ACPC rank was 281.Best of Luck for you Jee Mains !!P.S. Just an advice: if you are from CBSE board, you should not take chance and apply from both ACPC and AIR quota since the percentile of CBSE board will ruin your rank in both all India rank list and ACPC list. You need to have a very high percentage in PCM to have a decent rank.

Purposes of Specifications Purpose of specification is to highlight the necessary information which cannot be obtained from drawing. Further main purposes of writing specifications are; To show the strength of construction material or construction work.

In PHP, the $_POST variable is used to collect values from HTML forms using method post. Information sent from a form with the POST method is invisible and has no limits on the amount of information to send.

The $_POST variable is an array of variable names and values sent by the HTTP POST method. The $_POST variable is used to collect values from a form with method=”post”. Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.

Simply returning the web page is a GET request. There are also POST, PUT, DELETE, HEAD, OPTIONS and these are all used in RESTful programming interfaces. ... The protocol does not allow for anything other than simple, scalar datatype as parameters in a GET — e.g. you can only send a file using POST or PUT.

The difference between POST and PUT is that PUT is idempotent, that means, calling the same PUT request multiple times will always produce the same result(that is no side effect), while on the other hand, calling a POST request repeatedly may have (additional) side effects of creating the same resource multiple times.
