Internet bill format for Technical Support

bill nye here i'm back to answer some of your science questions this is science support part two [Music] angel supreme could be angel suprema if the earth is round why doesn't all the water fall off the water is held on the earth by gravity and get this so is the air wait there's more not only is the earth gravitationally pulling on the water the water is ever so slightly gravitationally pulling on the earth and see this is isaac newton's insight he saw the apple fall off the tree and he realized that not only is the earth somehow pulling the apple down but the apple is mutually gravitationally pulling the earth up like dude that's so out there i know i know miss misery how charming my dad i don't get the internet seriously where does it come from like how does it work the internet is a system of computers and we are able to store information for example an alphabet or numbers can be represented by a code that everyone's agreed on and the code is a pattern or a system of binary bits this is to say either ons or offs and you sir uh miss misery's dad i'll bet you're of a certain age where you remember morse code morse code is the same thing it's either a dot or a dash a dit or a da so we've taken it to a whole another level of dits and daws where we are able to store and transmit billions and trillions and quadrillions and sextillions of bits to represent language numbers calculations and you're part of this greater whole what a time to be alive man way to go chelsea briggs whoa did a meteor just hit my home state of michigan everyone is calling me is the world coming to an end uh i would say based on my presence here along you can't see it but there's a crew of camera and audio people here i don't think the world ended as we know it just judging insofar as you were able to send the text i bet the world didn't end for you either so once in a while a meteor streaks through the sky now for fun i'll give you these three words meteor means something streaking through the sky meteor has to do with the sky in greek a meteorite is what you call it when it makes it all the way to the earth's surface as an intact rock an asteroid is different a comet is different i guess that's four words but yeah meteors come into our atmosphere streak through the sky all the time meteorites once in a while if you like to worry about things you're living at a great time because we discovered that the ancient dinosaurs were almost certainly wiped out by a great big asteroid or a cluster of asteroids why can't i walk through solid objects if all i'm made of is neurons protons and electrons so let me say i think you tossed in the word neuron when you may have meant neutron but neurons enable you to think about this and keep in mind that protons and electrons are not all you're made of there's also some energy driving these things around making them interact and there are this fabulous subatomic particles the subatomic particles are in turn made of others even smaller particles quarks and so these things all interact and if you like to wonder about things this is a great thing we are made of protons neutrons and electrons and the reason you can't walk through solid objects the reason objects like you are solid is because these things especially the electrons repel each other so when you try to push on something the electrons repel each other so strongly that we perceive it as a solid object all the electrons neutrons and protons came together and they are almost entirely made of exploded ancient stars so you and i are made of stardust you and i are at least one way that the universe knows itself whoa dude i hope that fills you with reverence i hope you stop and think about that at least once every day middle school span teacher to true are the seats in the front of the plane the best to avoid turbulence generally yeah uh especially swept wing aircraft will do this and it reminded some aeronautical engineers of a dutch person on ice skates so traditionally it's called dutch roll and you damp out the dutch roll with the rudder on the vertical tail so yeah generally the front of an airplane is smoother than the back but this is a pretty subtle effect in the modern world maybe on an old md-80 or dc-9 mcdonald douglas-9 aircraft or maybe even on md-80 and maybe even an old 707 you'd feel that but nowadays hardly ever why because of the coupling of stability and control and our understanding of computers and our ability to have computers to not only do uh position velocity acceleration and jerk but also snap whoa carry on sit wherever you like that alicia underscore blackberry writes does anyone really know how gravity works the answer is we know with extraordinary precision what gravity will do we can land spacecraft on mars taking into account general and special relativity the speed of the spacecraft and the influence of the earth's gravity on the rate at which we perceive time passing we can take that into account to have your cell phone tell you which side of the street you're standing on we can do that but where gravity actually comes from remains a mystery alicia blackbeard you are living at a time when we may discover how this happens last summer we built these big interferometry gravitational observatories and we observed the ripple of a very strong gravity wave all the other energy that we can come across like the energy the light that's bouncing off my head and going into this camera lens and then off your computer screen into you we understand that very well and we use waves to analyze this flow of energy well people who discovered relativity einstein's the famous guy realized that gravity should perhaps also travel in waves and we could make predictions with that and we built these observatories and we've discovered them proved that they existed who knows what the future holds it's an exciting time go wild shea at singer underscore shay 17. if trees produce oxygen then can't paper do the same thing if it's made out of trees i i understand the premise of your question but compare how well a fish swims when it's alive with how well it swims after you've caught it and killed it we make paper out of dead trees dead trees don't move around as much and they don't produce nearly as much oxygen carry on shave jules watch them i was just thinking that's good i'm glad jules as artificial intelligence becomes more intelligent we might want to stop using the term artificial to describe it i mean the best ai is one that learns itself right so is it really artificial either way let's not start off on the wrong foot heart symbol icon emoji thing uh artificial intelligence gets the term because humans created computers that act as though they are what you and i call intelligent for me the line that will be crossed is when our computer systems which are artificially intelligent choose to make art when an artificial intelligence decides to do something just for the sake of doing it then we will have crossed a line into intelligence so right now i'd stick with ai and don't be freaked out about a.i you get on a you go to an airport you get on the tram that takes you from terminal a to terminal c and you trust it because engineers have designed a system that figures out how much you weigh how much your luggage weighs how fast the door should open where it should stop how fast it should accelerate how fast it should slow down gets all that done and you trust it it's just the next few levels with the thing will get more and more complicated what we don't want is for worldwide systems of the artificial intelligence to become so sophisticated that we can't predict what they're going to do or there's so many moving parts you can't tell what's going to happen that's what we don't want that's how we get blackouts and electrical grids and stuff but you're out there jules you're thinking deep thoughts way to go at a yo tristan did i just hear thunder in a snowstorm is that a thing yeah it's a thing thunderstorms happen when it's cold enough for snow to form and you know what you observe that yourself way to go yokimo at yoshiflo13157012 writes i have no pinky toenail is this evolution you'll notice that in evolution what's an interesting thing a fascinating thing a very important idea in evolution yokimo you don't have to be any better than you have to be this is to say there is no force no natural force no natural selecting pressure to have superpowers to have x-ray vision to be able to run faster than a speeding locomotive or leap tall buildings in a single bound there's no motivation for that naturally you only have to be good enough so if you're able to live your life put on shoes run marathons whatever you might do dance swing dances maybe the balboa or the collegiate shag or east coast swing you can do all that without a toenail there's no evolutionary pressure for you to get one but it's a cool question and you know what else yokimo i bet you really have one it's just the nail bed is really small i'm back carry on at vladimir older question if hashtag climate change that caused the end of the last ice age was a good thing why is hashtag climate change today a bad thing can anyone explain first you know as we say in comedy by the premise by the bit what makes you think climate change the cause of the ice age was a good thing ogg and aguette over there and what is now france they had it going on they lived in caves they hunted gathered and scavenged they had sex they carried on who knows what they buried their dead carefully why was that a good thing everything got hot people started walking all over the earth i mean was that really good but why the reason climate change today is a bad thing is the speed it's the rate at which humans like you and i are causing climate change that's the problem you and i are causing climate change and it's the speed people are going to have to abandon coastal cities as their floods come in more and more frequently the pests that infect our crops pests are showing up earlier and sticking around later it's the speed vladimir alder that is the trouble and whether or not ice age ending was a good thing it depends on whom you ask go out there if you go back in time take a meeting with ogg and i'll get and see if they thought it was great when they're mosquitos all the time suck man brunette love seven writes at bill nye my boyfriend and i have been debating if water is wet i went into the convo conversation thinking it is but he is adamant water is not wet can you please explain the science behind the answer to this question for me wet is sort of defined by water yeah so if there's water present it's generally going to be wet with that said we in fluid mechanics think of air wetting the surface of a baseball or a bird's wing or an airplane we talk about wetting and here's the definition of wetting from a fluid mechanical standpoint for your consideration myra brunetta it's when the fluid sticks to the surface air is a fluid anything that flows is a fluid so if it sticks to the surface then the surface is wetted so try this get a flask spin it with water in it spin it and you'll see the water takes on some of the spin of the glass because it's stuck to the surface take a ping-pong ball and give it a lot of spin either with a racket a paddle or your fingers the air sticking to the surface wetting the surface influences its flake but now whacks the hood of a car and put water droplets on it they beat up they don't wet the surface whoa thank you for these questions i'm really glad you all are pondering these things i am not some brilliant guy okay i'm just scientifically literate but the questions so far have been addressed in science and they're very well understood and you and i depend on them that's why we have shapes made of glass and lenses and drinkable water and electronic computer machines is because of science carry on people
