How do I manage SAFE and Convertible Noteholders when raising my Series A? The proliferation of SAFEs and Convertible Notes the past few years has given rise to a new problem when raising your Series A financing – “party rounds” with a lot of stakeholders who prove difficult to manage.More and more, we are seeing Series A companies with a signNow number of outstanding converting securities. The range for Series A financings we have worked on in 2017 and 2018 has been anywhere from twenty to sixty converting securities, with the majority being SAFEs. Total Seed financing has increased such that the range we are now seeing is a couple of million dollars up to ar...

Very much true.The US military has massive power projection, more than any country in the history of man. The US has 11 (CATOBAR/STOBAR) Aircraft Carriers, while the next country has 1 which is, China, Russia, India, UK, and France. Also, the US Carriers are not just regular carriers, they are known as Super Carriers. Which is a term coined by the public to say that these carriers are so large that they exceed the definition of an Aircraft Carrier. Also, the US carriers were designed in the 70’s and countries are now just starting to make designs that could compete with the American Carriers. However, the US just redesigned the carrier and is coming out with the new Gerald R. Ford Class Carrier, which is supposed to be years possibly decades ahead of any other countries design. If you include Helicopter Carriers, and Amphibious Assault ships, that number jumps up to 20, soon to be 22. Then the next highest is tied between Japan and France with 4. My favorite part about the US having so many Aicraft Carriers is that if we divided them up between the major oceans, we could have 4 in each ocean… Crazy. The US carriers are also nuclear powered, they are the only carriers to be nuclear powered besides the French R91 Charles de Gaulle.Note the types of planes on the US Carriers. If you look at the USS Gerald R. Ford, it is fielding 5 different aircraft. 4 planes and 1 helicopter. We will look at the planes. Woden note, the USN has the 2nd largest Air Force in the world, right behind the USAF.First plane- McDonnell Douglas F/A-18 Hornet/Super Hornet: The plane is one of the most decorated planes, with thousands of successful missions, while requiring 3x less maintenance and failures than its counterparts. The plane has electronic warfare capabilities, air to air, and air to ground capabilities. Also, has spy and early warning capabilities. It was one of the first aircraft to heavily use multifunction displays, which at the switch of a button allow a pilot to perform either fighter or attack roles or both. The airframe is complex yet so simple, that a 4 man team can remove and install a new F404 engine in 40 minutes. Was also one of the very first 4th generation fighter on an aircraft carrier.Second plane- Northrop Grumman X-47B: This guy will be the very first and only Carrier based Drone. Northrop Grumman intends to develop the prototype X-47B into a battlefield-ready aircraft, the Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) system, which will enter service in the 2020s. So it’ll have strike options and surveillance capabilities.Third plane- Northrop Grumman E-2 Hawkeye: Many countries have AWAC systems or Airborne early warning and control. But only the United States have a Carrier based AWAC system. With the creation of this system, carriers that are hundreds of miles away from the nearest AWAC system, this plane gives the ability for a carrier strike group to potentially detect fifth-generation fighters like the Russian Sukhoi Su-57 and the Chinese Chengdu J-20 and Shenyang J-31 farther out. Also, gives the ability to guide fleet weapons, such as AIM-120 AMRAAM and SM-6 missiles, onto targets beyond a launch platform's detection range or capabilities.Fourth plane- Lockheed Martin F-35C Lightning II: This plane is the first and only carrier based 5th Generation Stealth fighter. The plane is meant as an air superiority fighter and a plane capable of ground support. It also has a very low, almost undetectable, cross section and radar signature. Besides radar stealth measures, the F-35 incorporates infrared signature and visual signature reduction measures. With the addition of a 5th generation stealth fighter, this gives the US military and Navy, the opportunity to do more damage and to have true air superiority over all other aircraft carrier based planes and land based planes. The US, in the event of a war, can now bring 5th gen fighters to the battle without the need of the Air Force against other 4th gen fighters, or possibly the few Chinese or Russian 5th gen fighters.Furthermore, the US have some of the best destroyers on the planet. With the highly acclaimed Arleigh-Burke Class Destroyer, and the brand new, low production Zumwalt Class Destroyer. The US has the most destroyers in the world with about double the next country, with another 4 undergoing sea trials and we are currently building 5 more and have awarded contracts for 5 more. By 2024 the US is expected to have 79 destroyers in service.Zumwalt Destroyer- The Zumwalt class warships are the largest destroyer ever built. The USS Zumwalt has unusual hull design optimized for wave piercing. There is a composite deckhouse. Angular shape minimizes its radar signature. The ship has hidden radar and sensors. The despite its size the USS Zumwalt has a radar signature of a fishing boat. Also it has reduced sound and infrared signature what makes this ship harder to detect. The ship is the First american surface warship to integrate electronic propulsion, it generates enough power to light up a small city. Sound levels of the Zumwalt are comparable with Los Angeles class submarines.Arleigh-Burke Destroyer- These guided missile destroyers entered service with the US Navy in 1991 were the first large US Navy vessel designed to incorporate stealth shaping techniques to reduce radar cross-section. Also these are one of the biggest destroyers in the world that incorporate highly advanced weaponry and systems. Hull profile of the Arleight Burke class signNowly improves seakeeping, permitting high speeds to be maintained in difficult sea states. The AN/SPY-1D phased array radar incorporates signNow advances in the detection capabilities of the AEGIS weapons system, particularly in its resistance to enemy electronic countermeasures. Missile are stored in vertical launch systems, that can also house smaller Evolved Sea Sparrow (ESSM) missiles, Tomahawk land attack cruise missiles, ASROC anti-submarine missiles. For point defense the ships are equipped with two Phalanx Close-In Weapon Systems (CIWS). Also there are 324 mm launchers for Mk.46 or Mk.50 torpedoes.Daily dose of freedom right here.Obviously, we can’t forget about the immaculate US submarine fleet. The US has some of the most advanced and quietest submarines. All of them use nuclear propulsion for extended range and stealth capabilities. The US has the…Ohio class (18 in commission) – 14 ballistic missile submarines (SSBNs), 4 guided missile submarines (SSGNs)- The U.S. Ohio-class submarines, of which 14 are Trident II SSBN, each capable of carrying 24 SLBMs. The first four which were all equipped with the older Trident I missiles have been converted to SSGN's each capable of carrying 154 Tomahawk guided missiles and have been further equipped to support Special OperationsSeawolf class (3 in commission) – attack submarines- The Seawolf class boats were intended to seek and destroy the latest Soviet ballistic missile submarines, such as the Typhoon class and attack submarines such as the Akula class. Seawolf class submarines are arguably the quietest submarines in the world ever constructed. It is exceptionally quiet even at high speeds. Most submarines need to keep their speed down to as little as 5 knots to avoid detection by passive sonar arrays, while the Seawolf class are credited with being able to cruise at 20 kots and still be impossible to locate. A Seawolf at 25 knots makes less noise than an older Los Angeles class submarine tied up alongside the pier. And these came out in 1989.Virginia class (11 in commission, 5 under construction, 2 on order) – fast attack submarines- The Virginia class submarines incorporate newly designed anechoic coating, isolated deck structures and new design of propulsor to achieve low acoustic signature. It is claimed that noise level of the Virginia is equal to that of the Seawolf class. The Virginia class submarines are fitted with 12 vertical launch system (VLS) tubes. These are used to launched Tomahawk land attack cruise missiles with a range of 1 700 km. Also there are four 533-mm torpedo tubes. These are used to fire a total of 26 Mk.48 heavyweight torpedoes and Sub-Harpoon anti-ship missiles. It is the first US submarine to employ a built-in Navy SEAL staging area allowing a team of 9 men to enter and leave the submarine.(Improved) Los Angeles class (34 in commission, 2 in reserve) – attack submarines- The Improved submarines are much quieter. It is described that improved Los Angeles class boats are 7 times quieter than the original Los Angeles class boats. The class features a very potent weapon array, including Mk.48 torpedoes, Sub-Harpoon anti-ship missiles and Tomahawk land attack cruise missiles. Tomahawk missiles can be launched from torpedo tubes of from dedicated vertical launching systems. These boats can operate under ice where the Russian ballistic missile submarines tend to hide.Surfacing of a US Submarine.Let’s move onto the air. While the USN has a quite capable Air Force. But that is dwarfed by the sheer magnitude and strength of the United States Air Force. The Air Force articulates its core missions as air and space superiority, global integrated ISR, rapid global mobility, global strike, and command and control. The USAF flys a multitude of different planes and helicopters. The USAF is the largest Air Force in the world, here is the list of what America flys. Most of these are at the cutting edge of innovation, with two of them being 5th generation stealth fighters. That’s really really good because no other country has an active 5th gen while the US has 2. The USAF also has the largest bomber, tanker, fighter, and transport fleets in the world. The USAF has so many staging areas around the world, that the US can have bombers or any other planes on station, anywhere around the world in a matter of hours.Attack: A-10, AC-130, MQ-1, MQ-9Bomber: B-1B, B-2, B-52HElectronic warfare: E-3, E-8, EC-130Fighter: F-15C, F-15E, F-16, F-22 (5th gen), F-35A (5th gen)Helicopter: HH-60, UH-1NReconnaissance: MC-12, RC-135, RQ-4, RQ-170, U-2, U-28Trainer: T-1, T-6, T-38, T-41, T-51, T-53, TG-16Transport: C-5, C-12, C-17, C-21, C-32, C-37, C-130, C-40, CV-22, VC-25Tanker: KC-10, KC-135Let’s look at the two of my favorite ones and the most technologically advanced planes in the world.F-22 RaptorThe F-22 Raptor air superiority fighter is almost invisible to radars. This aircraft carries a powerful array of weaponry. It is the most advanced and most expensive production fighter aircraft to date. Many of sensors and avionics of this plane remain classified. Engines of the raptor allow the aircraft to supercruise over long ranges, while thrust-vectoring nozzles, combined with a triplex fly-by-wire flight control system, make it exceptionally maneuverable. The highly integrated avionics systems also include a data-link, inertial navigation system with embedded GPS for high-accuracy navigation, and advanced electronic warfare, warning and countermeasures systems. Two central computers manage the automatic switching of the sensors between completely passive and wholly active operation, according to the tactical situation. Artificial intelligence algorithms fuse data from the sensors and present only relevant information to the pilot to reduce workload while at the same time improving tactical awareness. The datalink allows tactical information to be shared with other F-22s. The tech is so special that other countries, not even NATO allies are given the chance to procure the plane.B-2 SpiritThe B-2A Spirit is the silver bullet of US policy, reserved for use against targets of the highest priority. The B-2's stealth characteristics enable the undetected penetration of sophisticated anti-aircraft defenses and to attack even heavily defended targets. This stealth comes from a combination of reduced acoustic, infrared, visual and radar signatures (multi-spectral camouflage) to evade the various detection systems that could be used to detect and be used to direct attacks against an aircraft. Composites are extensively used to provide a radar-absorbent honeycomb structure; the bomber has a minimal IR signature, does not contrail and uses its shielded APQ-181 radar only momentarily to identify a target just before attacking. The onboard DMS is capable of automatically assessing the detection capabilities of identified threats and indicated targets. The DMS will be upgraded by 2021 to detect radar emissions from air defenses to allow changes to the auto-router's mission planning information while in-flight so it can receive new data quickly to plan a route that minimizes exposure to dangers. Also, most of the B-2s are stationed in Missouri, and they are capable of bombing any target in the world despite being in the heart of America.Now for the US ARMYThe US army it self is massive in numbers, coming in at 1.01 million personnel, it self is one of the biggest standing armies in the world, and that's just one branch of the US military. Also, in the US military, it is the largest branch out of them all surpassing any other branch by almost 600,000 personnel. They provide the bulk of security for the US's foreign interests. The mission of the U.S. Army is to fight and win our Nation's wars, by providing prompt, sustained, land dominance, across the full range of military operations and the spectrum of conflict, in support of combatant commanders. Which is mainly air domination and land domination. They mainly engage is conventional warfare, and asymmetrical warfare. The US Army's main responsibilities is preserving the peace and security and providing for the defense of the United States, the Commonwealths and possessions and any areas occupied by the United States, Supporting the national policies, Implementing the national objectives, Overcoming any nations responsible for aggressive acts that imperil the peace and security of the United States. The US Army is also home to some of the most dangerous, prestigious and hardest working special forces teams in the world such as the frontline special force, the Rangers, we also have the green berets and the iconic 1st Special Forces Operational Detachment-Delta (Airborne) also known as Delta Force. The US army is thought to be one of the most battle tested and battle proven militaries in the world. With the mobility of the USAF an army QRF can be anywhere on earth in less than 24 hours. The US ARMY uses the M1A2 Abrams tank. One of the most badass, heaviest, fastest, and battle hardened tanks in the world.This tank has incredible technology and armor. Also it has seen combat. It is one of the most feared MBTs. The M1A2 offers signNow protection against all well-known anti-tank weapons. This main battle tank uses advanced armor, reinforced with depleted uranium layers. The M1A2 has signNow level of protection against all known anti-tank weapons. It can also employ counter-IED equipment. The tank is armed with the same 120-mm M256 smoothbore gun as its predecessor. Range of effective fire is in excess of 4 km. This main battle tank is powered by a Honeywell AGT1500 gas turbine engine, developing 1 500 hp. The tank is one of the fastest in the world, clocking in (with no governor) at 60 mph while being THE heaviest tank in the world. As of April of 2018, the US has no combat losses with the Abrams, the Abrams has only been lost due to friendly fire, never to enemy fire.I don’t think I need to explain the marines. Just know that they use the same tech as the Army (with some exceptions) but they are also the main invasion force for the US. And they are badass.The US military signNow is massive with the Aircraft carriers and the 700+ military bases around the world. The US is truly the most powerful military in the world. The fact that they can have a men anywhere in the world in less than 24 hours and being able to bomb any place on earth, just proves how powerful the US military is.

Indian Air Force is an interesting topic to read and know about with many jaw-dropping facts that are particularly unbeknownst to the general populace of one of the largest air forces in the world. Here I will discuss some 11 amazing facts about the Indian Air Force from past and the present which I hope , people would like to know about :A. When IAF inducted 140 Fighters in just 1.5 years !You read that right. After the 1965 Indo-Pak War , Indian Air Force was heavily modernizing its combat fleet and to stop the squadron numbers from diminishing. For this purpose , Sukhoi Su-7 was selected which was the first Sukhoi to serve in Indian Air Force. The procurement were done in a record time which were quite unprecedented as Indian Air Force went on to induct 140 Su-7 in just 1.5 Years which was almost 8 Fighters each month. No.26 Squadron first converted to Su-7 followed by No.101 Squadron and during the induction process , IAF raised some 6 Strike Squadrons which served with distinction during the 1971 Indo-Pak War.B. When an Indian Air Force Mig-25 shot the sun !A Lamborghini Huracan Avio posing in front of the MiG-25 Foxbat at Indian Air Force Museum at Palam AFSOn 24th October 1995 , an IAF Mig-25 ‘Garuda’ flown by Group Captain, Air Marshal Mukerji shot the sun during the total solar eclipse which might sound simple but was quite challenging as the pilots were required to be specialized in navigation and earth’s geometry. An upward looking camera was cued by the pilot towards the sun while another pilot flew the ‘Garuda’ in the exact direction as the earth rotated around the sun. They filmed the magnificent scene from the stratosphere for one and more minutes. Mig-25 was one of the legends of Indian Air Force which served as a Strategic Reconnaissance Aircraft and its presence was kept as a secret for many years as it flew many hostile High-Risk Sorties in enemy airspace clicking high defenition pictures of enemy installments on the ground.C. Indian Air Force ‘Mammoth Formation’ :The largest Indian Air Force Formation flew from Ambala Air Force Station on 1987–88 which was nicknamed the “Mammoth Formation”. These aircrafts consisted of Canberra Bomber Aircraft , Mig-25 “Garuda” , Mig-29 “Baaz” , Ajeet , Mirage 2000 , Mig-27 “Bahadur” , Hawker Hunter , Jaguar “Shamsher” , Mig-23MF and finally the good-old Mig-21.D. When an Indian Air Force Military Transport Aircraft flew without using propellers :Here is an Indian Air Force C-119G Flying Boxcar Military Transport Aircraft somewhere in 1960s. If you closely notice this particular photo , the propellers are idle and the engine has been put off. Now you must be wondering how is this particular aircraft flying.This has been made possible only by its Orpheus Jet pod which has been placed on top of its fuselage. The aircraft is flying solely due to the power supplied by the pod as it was utilized by IAF to shorten the takeoff distance thereby enabling the aircraft of Short Takeoff and Landing Capabilities. IAF also used the J34 turbojet engine for short take-off and IAF’s C-119 also holds the record for being the first aircraft to take-off from the Daulat Beg Oldi with an Orpheus Pod.E. How was Garud Commando Force established :In early stages , PARA SF and MARCOS Officers advised the top brass of Indian Air Force to establish a dedicated Commando Force modeled on the Commando Force of Royal Air Force Regiment. They also advised IAF Officers to procure few numbers of C-130J Strategic Airlifters which can be used to air drop the Commandos in Combat Search and Rescue Missions and also in high-threat missions. Garuds were established on same lines as RAF Regiments and were trained on similar lines as PARA SF and MARCOS though the top brass of Indian Air Force did not pay heed to the second recommendation and no additional C-130J were procured.F. Indian Air Force was the first Air Force to Operate Fighter Jets in Asia :Indian Air Force inducted de Havilland Vampires with the No.7 Squadron “Battle Axes” in 1949 making Indian Air Force the first Air Force in Asia to induct Fighter Jets in its inventory. Vampire served in almost all Fighter Squadrons of Indian Air Force for a span of over 3 decades as a Fighter-Bomber and Reconnaissance Aircraft.G. Indian Air Force was the first Air Force to induct an indigenous Fighter Jet in Asia (outside Soviet Union ) :HF-24 was the first indigenous Fighter Jet which was inducted by an Asian Air Force outside Soviet Union. Conceptualized for Air Staff Requirement (ASR) as a Multi-Role Fighter jet , HF-24 was never realized to its true potential as it was primarily used as a Fighter-Bomber for Ground Attacks. It was inducted by No.10 Daggers Squadron of Indian Air Force in April 1967 making Indian Air Force the first Asian Air Force outside Soviet Union to induct an indigenously made Fighter Jet.H. When an Indian Air Force Mig-21 almost shot down an Indian Helicopter in a Special Operation :During 1971 Indo-Pak War , an Indian Alouette 3 helicopter was flying for a Special Operation in a hostile zone where no supposed friendlies were to be spotted. The helicopter was spotted by an Indian Air Force Mig-21 who decided to engage the helicopter by firing its 57mm Rockets , considering it an enemy asset , which was quickly dodged off by the Alouette Pilot. Realizing his miscalculation , he decided to re-engage the helicopter but that attack was also dodged off by the helicopter pilot. This time the Mig-21 pilot did not wanted to take any risk and closely approached the Helicopter and finally noticed the Indian markings on it. He sighed in relief as he has almost shot down the friendlies.I. Ashok Chakra Roundel for Indian Air Force :After Independence in 1947 , Indian Air Force adopted new markings for its Fighter Aircrafts in June 1948 to distinguish itself from the Royal Indian Air Force Markings. The roundel adopted by Indian Air Force was a ‘Ashok Chakra’ on the Fuselage and the wings. Since these roundels were difficult to paint in correct dimensions , they were soon replaced by Saffron White Green Roundels . Nevertheless these Ashok Chakra Roundels saw service during the 1947–48 Kashmir War when IAF Aircrafts flew with these markings.J. Missiles on Overwing Pylons !Indian Air Force utilized the unusual provision on the SEPECAT Jaguar Aircrafts to mount Air-to-Air Missiles like Matra R.550 Magic on overwing pylons thus freeing the underwing pylons to carry other weapons like Bombs and Missiles. The advantage of this was a quick height gain for Air-to-Air Missiles when they are launched at enemy interceptors at higher altitude who might arrive in the scene to intercept the low flying Jaguar Strike Aircraft. It also helped in additional payload carrying capacity for the Jaguars and is truly an amazing capability with an IAF Fighter still in service after 3 decades.K. First Indian Air Force Fighter with an InfraRed Search and Track System :IRST is a system deployed on Aircrafts to detect and track potential hostiles by scanning their Infrared Signatures. Indian Air Force was one of the first Air Force to deploy an IRST System on it's frontline Fighter Aircraft. IAF's Mig-23MF was fitted with TP-23 IRST at its undernose with the legacy continued by Su-30MKIs and Mig-29UPG at present and by Rafales in future.L. ‘Eye in the Sky' for Indian Air Force :India has acquired 3 EL/W-2090 Airborne Early Warning and Control Radar System from Israel to serve as the ‘Eye in the Sky' for Indian Air Force mounted on A-50EI Platform . This Radar System was adjudged as the most advanced AEW&C by Federation of American Scientists in 1999 and 2008 Articles. It can detect a fighter sized target at a distance of 500 kilometres relying on its L-Band AESA radar. It can also carry out L-band radar, then adds electronic and communications intelligence gathering (ELINT and COMINT ).Hope my answer serves the purpose =)References :Sukhoi-7 BMK - A whale of a fighterhttps://www.livefistdefence.com/...This Stunning Old Photo Of An IAF ‘Mammoth Formation’ Just Showed UpEL/W-2090 - WikipediaStory behind missiles over the wings (25 Photos)https://www.secretprojects.co.uk...Indian Air Force Gallery :: De Havilland Vampire F3 and FB52 (Single Seaters) - Bharat RakshakRoundels (Independence and Chakra)HAL HF-24 Marut - Wikipedia

To fulfill your stated requirements would require (1) a post the length of a book, and (2) a deeper understanding than I personally have. However, given that Quora is not the right place to write a book anyway, I may know enough to take a reasonable crack at this. With that said, though, if you're an actual expert on one of these areas and catch something I've explained incorrectly, please let me know in the comments so that I can fix it!Yes, it's still quite long, but keep in mind that this is the short version.What is Dark Matter (DM)?Dark Matter is just matter that doesn't interact via the Electromagnetic (EM) or Strong Nuclear forces. No EM interactions means that it can't give off light, or absorb light, or reflect, refract, or scatter light in any way. This, naturally, makes it rather difficult to see (thus "dark" matter, although I suppose it's more "transparent" than "dark"). Our current best measurements indicate that something like 85% of the matter in our observable Universe (about a quarter of the total mass-energy content) is Dark Matter.Isn't Dark Matter weird/spooky?Not at all. Neutrinos, for example, satisfy the definition of Dark Matter, they just represent such a tiny fraction of the total DM in the Universe that people tend to neglect them when they ask, "what is Dark Matter made of?"There is nothing at all strange or unusual about certain particles not interacting in certain ways. Neutrons have no electric charge (although they do have EM properties, but that's neither here nor there), and electrons don't interact via the Strong Force, so why shouldn't there be particles that interact with neither, like the neutrinos? Saying that interacting with light is "normal" is purely human bias, because we rely so much on sight. Having lots of DM in the Universe is in no way "weird"; it just means that the Universe doesn't revolve around what humanity finds convenient!Why are we confident that DM exists?This is by no means a complete list, but it should give a sense of the kinds of evidence we have. Each of these would take at least a chapter of a book to explain properly, but hopefully this will give the general idea.Galactic rotation curves.When one object orbits another, the orbiting object has to be constantly accelerating towards the central object (or, more precisely, they both accelerate towards their combined center of mass). Without that acceleration, the orbiting body would just fly off. The faster the orbiting body is moving, the more acceleration is needed to keep it in its orbit. Since in this case the acceleration is due to gravity, this means that the central mass has to be bigger. For a circular orbit of a small object [math]m[/math] at distance [math]r[/math] and velocity [math]v[/math] around a large (and assumed stationary) object [math]M[/math], the acceleration requirement gives[math]\frac{v^2}{r} = \frac{GM}{r^2}[/math]which in turn gives us the relation[math]v = \sqrt{\frac{GM}{r}}[/math].(I'm doing this with Newtonian gravity for simplicity; to do it with full rigor would require General Relativity. In this situation, the Newtonian approximation is actually generally pretty good.)For a more complicated object than just two point particles, as long as there's enough symmetry, the gravitational version of Gauss's law says that the relevant [math]M[/math] is the total mass of everything in the galaxy that's at a distance less than [math]r[/math] from the center. [Edited to note: For this to be exactly right, the matter distribution would have to be spherically symmetric, which galaxies aren't. As a result, actual calculations are a bit more complicated than shown here.]This allows us to "weigh" different parts of the galaxy, by measuring the relationship between [math]r[/math] and [math]v[/math]. (We can measure the rotational velocities by comparing redshifts on the approaching and receding sides of the galaxy.) This image from Wiki shows the result of this measurement:The "expected from visible disk" line is determined by adding up the masses of all the parts of the galaxy that we can see. (How we measure that mass is a whole different discussion.)Gravitational Lensing.In General Relativity, whenever light passes through a gravitational field, that field bends its path slightly. This acts like a Gravitational lens, and can produce, for example, "Einstein Rings", like this image from Wiki:The "ring" is a distorted image of a single blue galaxy located behind the red galaxy at the center. Light from the blue galaxy goes out in all directions, but is bent by the red galaxy's gravity. This means that the light that starting out on a "direct path" to us never signNowes us, but light that was originally missing us by a specific amount (in any direction) gets bent back towards us, which makes it look like it's coming from a bunch of different directions, resulting in the ring image seen here.This is a highly dramatic example of gravitational lensing, but there are much more subtle effects that can still be useful. In Weak gravitational lensing, statistical analysis of distortions in the light we receive allows us to "map out" the gravitational field between us and distant galaxies. Often, this just shows more mass than we know how to account for, but that could be explained away by just assuming that our understanding of gravity is off. There's something else, however, that's a lot harder to explain away in that manner: the Bullet Cluster.(Image from A Matter of Fact on nasa.gov)What's going on here? Well, two galaxy clusters collided with each other, and this is the aftermath. The red coloring represents where the visible matter is, while the blue coloring represents where the dark matter is, as inferred by gravitational lensing. Why are they separated so much? Well, most of the luminous matter in a galaxy cluster is in the Intracluster medium, a hot, dense, plasma. When these plasmas collide with each other, a signNow amount of the matter slows down. However, since Dark Matter interacts only very weakly, the DM components of the two clusters were free to pass through each other unimpeded, resulting in a separation (as seen here). Not only is there "not enough" luminous matter... it's in the wrong place! A small number of scientists remain committed to finding ways to explain this without DM, and they have had partial success, but only by including as-of-yet-unmeasured things that are far stranger than DM (for example, a rank-3 tensor field, which, while possible, would be the first tensor field of such a high rank ever found).Effect on the Cosmic Microwave Background.For the first few hundred thousand years after the Big Bang, The Universe was hot enough that it was highly ionized, which made it more or less opaque to light; photons were pinballing around just like any other particle. However, once things cooled down enough, signNow amounts of the protons and electrons combined into neutral Hydrogen, which is (more or less) transparent to most of the light that was around at the time. This happened fairly quickly (in terms of cosmological time), and so it was as if all of the light pinballing around all over the Universe were suddenly released all at once, effectively capturing a snapshot of the Universe at that moment in its evolution. Since this light was released everywhere in the Universe, we can point our radio telescopes in any direction we like, and there it is: the Cosmic microwave background (CMB). It's almost the same temperature in every direction, but there are small differences (generally around one part in [math]10^5[/math]), and we have measured these tiny variations with extraordinary accuracy: first via the COBE satellite, which was then replaced by the more advanced WMAP, which was then replaced by the more advanced Planck (spacecraft), which is currently in operation.These tiny variations can tell us a lot about the early universe. For example, statistical analyses of these variations show the distinct signature of pressure waves propagating through that early plasma, and the nature of these Baryon acoustic oscillations can tell us a lot about what kinds of things were around. Specifically, the protons and electrons would be dragged along by the (dominant) photons, becoming part of the wave, but Dark Matter wouldn't, and would only be indirectly affected by the resulting small changes in gravity. The presence and abundance of Dark Matter therefore affects how these waves impact the temperature variations in the CMB.The formation of large-scale structure.The standard story given in popular science explanations goes like this: the Universe started out hot and dense and more or less uniform, then it expanded and cooled and clumped into stars and galaxies. However, this story is incomplete, in a way that means that galaxies wouldn't exist without dark matter.At a surface level, the story makes sense; heck, I got almost half-way through a Ph.D. in Physics without noticing any problem with it! It sounds so plausible because of how gravity works: if matter is distributed more or less evenly, but some places are a tiny bit more dense than others, gravity will tend to make those overdensities bigger and bigger. Why? Well, even if a region is just a little denser than its neighbors, it's still going to win the gravitational tug-of-war and gradually accumulate more and more mass. Of course, once it has more mass, it wins the tug-of-war by even more, and so it's a run-away process that ends in big gravitationally-bound clumps.So, what's the problem? Well, consider the air in the room with you right now. Are there tiny density variations? Of course, since perfect uniformity is impossible. But, is it forming into exponentially denser clumps? Certainly not! The reason for this is that, under these kinds of conditions, when the density of a gas goes up, so does its pressure. That pressure makes the over-dense region expand outwards again, returning the density back to average!Now, of course, the scales and temperatures involved are totally different. A huge region of gas will have more gravitational attraction than a tiny pocket of denser air in your room, and gas in space has no need to be at room temperature, either. So, if the gas can cool down enough, that can reduce the pressure enough for gravity to win. But, the more it compresses, the more it heats up, because it's converting gravitational energy into thermal energy, and so the pressure goes up again. This means that forming a galaxy is a very gradual process, during which it has to constantly be getting rid of tremendous amounts of energy. If it were just a cloud of gas, without any outside interference, this process wouldn't be nearly fast enough, and we wouldn't have galaxies today.But, as you know, hot things give off heat much faster than cold things. So, if we want galaxies to form by the present day (or, indeed, before the expansion of space makes matter too dilute to form galaxies at all), something has to be forcing the gas to compress and become denser and hotter than it would be able to under its own gravity. Enter: Dark Matter. Because it interacts only weakly, Dark Matter doesn't have pressure like gas does. So, the argument about the run-away gravitational process actually works for Dark Matter. DM can't get rid of energy very easily, and so conservation of energy and angular momentum mean that it can only collapse to about 200 times the background density, but the resulting Dark matter halo provides enough of a gravity well to "seed" the formation of visible galaxies. So, it's not a coincidence that the galactic rotational curves showed large amounts of dark matter... the galaxies wouldn't have formed there without it!As a result of this DM "seeding" process, theoretical models and computer simulations of the formation of DM structures have been fairly successful in describing the statistical properties of how galaxies are distributed now, as well as how they were distributed earlier in the history of the Universe (which we can measure by looking at very distant galaxies).Okay, so that's why we think Dark Matter exists. But, the next obvious question is... well... what is it? What's it actually made of? What are its properties? Here, we have only very partial knowledge, and multiple different theories, any combination of which could be correct (or, perhaps, none of them). This leads us to:What do we know about the properties of Dark Matter?Again, this is in no way exhaustive, but it should give you a decent idea.It's "cold".This is why the current dominant model of cosmology is called the Lambda-CDM model: "Lambda" ([math]\Lambda[/math]) stands for the Cosmological constant, and "CDM" stands for "Cold Dark Matter".When an astrophysicist describes something as "cold", they generally mean that the associated thermal velocity is much less than the speed of light. By this standard, the air in Death Valley is "cold". But, then again, to cosmologists, galaxies are basically point-particles, so everything's a matter of scale and perspective!So, why does DM need to be "cold"? Well, remember that DM clumping together was integral to the formation of structures like galaxies. However, if DM were very hot (and therefore the particles were moving very fast), this would prevent it from clumping properly. I have explained it in very vague terms, but the effects are actually well-understood mathematically. In fact, it's similar to something that does happen, with photons: Diffusion damping (or "Silk damping"). However, in the case of Dark Matter, the result would be a signNow delay (or even outright prevention) of the formation of galaxies, to the extent that "warm" Dark Matter can be observationally ruled out.Incidentally, this is how we know that it's not all just neutrinos: given what we know about the early Universe, they would be far too hot!It interacts only very weakly.This is somewhat part of the definition of Dark Matter, but it's good to see observational confirmation. I know fewer of the details on this, but I do know that there are observational bounds in the "interaction cross-section" of Dark Matter, both in terms of its interactions with luminous matter and for its theorized self-annihilation processes (in which two DM particles could interact and annihilate each other). Also, as discussed before, the Bullet Cluster shows giant dark matter halos more or less just passing through each other, which suggests very weak interactions.So... given those properties,What might Dark Matter be made of?There are two leading theories (as far as I'm aware) that suggest the existence of specific types of new particles. Both are well-motivated theoretically (as in, we have good reasons for suspecting that particles with those particular properties might exist), but neither has been experimentally confirmed yet. Interestingly, the two predicted particles are totally different from one another, not slight variations on the same theme.At the end of the day, either of these theories could be right, or both (given the existence of neutrinos, there's no need for all the rest of the DM to be a single type of particle), or, of course, neither.So, what are the theories?Axions.I feel morally obliged to put this one first, even though the other one is more popular at the moment, because my university is heavily involved in the Axion Dark Matter Experiment (ADMX), and so of course I'm rooting for my colleagues!The existence of Axions has been theorized since the 1970s, but we only recently have the technology to even properly start to try to measure them in the lab. Axions are extremely tiny particles (unlike WIMPs, the other leading option), and so they would have to exist in truly huge quantities. Still, because they interact so weakly, it's hard to detect them, even with billions of them passing through your detector in a tiny fraction of a second. The linked wiki articles do a better job of explaining the theoretical motivation and experimental search than I could. It's really quite elegant, and would solve a lot of outstanding mysteries in particle physics (like the Strong CP Problem), but I can't do it justice.Weakly Interacting Massive Particles (WIMPs)(Wiki reference: Weakly interacting massive particles)To explain why WIMPs are theoretically attractive, I have to take a little detour into "relic abundance", i.e., how many particles of a given type were left over after the Universe cooled down and generally became a more stable place.In the early universe, everything was very dense, and many different kinds of particles were "tightly coupled" (i.e., they interacted with each other frequently). However, as the universe got larger and cooler, these interaction rates slowed down, more or less to a stop, a phenomenon known as "freezing out". The time at which something "freezes out" depends on a number of things, including its mass and how strongly it interacts with other things. This "freezing out" has a huge effect on the abundances of various particles in the Universe. For example, consider the process[math]n \Leftrightarrow p + e^- + \overline{\nu_e}[/math],in which a neutron can turn into a proton, electron, and electron anti-neutrino (or vice versa). If you go back far enough, this reaction will be in thermodynamic equilibrium, just like with any chemical reaction that can go either direction. However, once the neutrinos "freeze out", equilibrium can't be maintained anymore (although other processes, like beta decay, can still happen). The relative abundance of protons and neutrons at the moment of freeze-out is determined by two factors: the mass difference [math]\Delta m[/math] between the two particles, and the temperature of the Universe when freeze-out occurred. These factors combine to determine by how much the lighter particle is thermodynamically favored, with an exponential dependence:[math] \frac{N_n}{N_p} \propto e^{-\Delta m c^2 / k T}[/math]where [math]k[/math] is Boltzmann's constant.This clearly impacts the "relic abundance" of the particles involved (here, protons and neutrons). So, in general, the abundance of a given particle in the Universe today is signNowly influenced by the mass of that particle and how strongly it interacts (since that affects freeze-out time and thus freeze-out temperature). This brings us to the so-called "WIMP miracle": a particle that interacts predominantly via the Weak Nuclear Force, and that has a mass near the mass scale associated with Weak interactions ([math]\sim 100 \text{ GeV}/c^2[/math]), would have a relic abundance that would match the measured abundance of Dark Matter in the Universe. Given that such a particle was already speculated to exist (in the context of Supersymmetry), this was very theoretically attractive to a lot of people, although our inability to find it so far has damped some of their spirits.So, there you have it: my summary of Dark Matter. Hope it was worth the time it took to read! (Let alone write...)

I think that we all agree that the days of manual prospecting are long gone. If you automate your prospecting efforts you can save a lot of time and money, and streamline your whole sales process. But, since there are lots of prospecting tools in the market, it can be hard to figure out which ones are good and which ones you should avoid.I’ll give you a couple of suggestions based on the tools I used.Email Hunter is a decent little program that can extract a list of every single one company email. All you need to enter is a company domain, and you will soon be able to email any person from a company. You can use either its dedicated Chrome plugin, or you can do your search by means of their browser version. This program can come in really handy if you want to find the email of a particular decision maker and get in touch with them directly.HeadsignNow is another interesting tool that offers more options than Email Hunter as it has some advanced search features. This means that you can search prospects based on various criteria such as name, company, title, or website. You can also expect to find your prospects’ social media handles and memorize your search logs.Autoklose isn’t your average prospecting tool, mainly because it offers much more. It’s actually a sales automation platform that can dramatically speed up your sales cycle, and prospecting is just one of the weapons in its arsenal. Apart from automating your prospecting efforts and saving you a tremendous amount of time, Autoklose will make your job and life easier by automating your email marketing efforts, amplifying your follow-ups, providing you with detailed campaign stats and metrics, and streamlining numerous dull, repetitive tasks that have to be done during the sales process.When it comes to prospecting, Autoklose allows you several powerful methods of filling your funnel with quality leads.Upload your own reliable contacts from .CSV files and Autoklose will import the information in the database so that you can make lists according to various parameters, and additionally segment them in order to create customized outsignNow campaigns and improve your open and click-through rates;Connect your Salesforce account and sync the data with Autoklose thus growing your internal database. What’s great about this platform is that it prevents you from sending the same email to the same person twice;Gain access to a huge B2B leads database and find prospects from virtually any industry. I was impressed with the abundance of prospects that I could actually contact. This database is managed by Autoklose’s reliable third-party providers, and it’s absolutely clean and packed with verified, complete, and updated contact information.It’s clear that Autoklose gives you a plenty of prospecting options, and the fact that you can search for your potential customers by using different parameters makes it in a way similar to HeadsignNow, but one of the main and most important differences is that Autoklose provides you with validated data which undergoes a meticulous 50-point data-scrub, meaning that every missing field is filled in, and every email, phone number, address, and job title is checked both manually and through the proprietary technology. To cut the long story short, Autoklose keeps you covered and gives your prospecting a big boost.
