Why Does This Lake Make Laser Sounds? | [OFFICE HOURS] Podcast #040

how about now what about now is it working it's good here we go well welcome to i almost had a uh slight breakdown in my mental health where i was i was going to um i was gonna try to do the entire thing with hand signals but i realized that this whole first segment is all about sound and then i was freaking out okay so i know that i can shut down the streaming and then come right okay hey hello i'm gonna cut this whole first part out so uh look um yeah okay i'm gonna eat your face bye hello and welcome oh i didn't hang up hello and welcome to office hours the companion show uh to the facility where good old professor kyle opens up his blast doors fixes his audio issues for about 10 minutes and takes all of your questions from the chat and from all of my lovely professors here at the facility we also go through a number of different topics as we want to do each week things that made me say hello some of those topics include this beautiful lake and why it sounds like laser beams we're also going to be talking about tom hanks tom hanks science communication super intelligence and the problems thereof or therewith and education now who's that smart boy also if you want to continue on this conversation after this live stream without any audio issues because there's no audio you can go to patreon.com kyle hill right now and sign up for the patreon get into the discord talk with me almost every day i'm a little bit flustered my security team's also in the chat they know that they're doing their best do you know what else is doing their best people who are using youtube super chats if you really really want me to see your comment i will try my very best with my very best audio to get to all of you who are super chatting here on youtube for example elizabeth calvert as she always does the beginning the stream with the 20 says i'm gonna do smaller sims for a while it's fine i don't need new microphones don't give me money my tiny human wants to know if there's a way to uh use lightning to power devices when it goes out um also i have to tell you this joke uh from my tiny human don't trust an atom they literally make up everything alex that's not bad yes i know the name of her son it's not weird we're friends but a lot of you uh doing something similar with the super champs like c c car with huf 1000 it says here buy a better robot sound filter i was trying to sound cool you got to leave me alone on that aspect i have people text i have friends and family texting yeah thank you yeah alyssa i know i i did close the program geez how did she even get my number i don't anyway so we're gonna be going through a number of topics this week while i'm not frazzled of course um chef smoke one of my oldest supporters says with the 50 you fixed it oh and i i did fix it and i'm freaking out a little bit so before we get to all of your stuff let's get to the very first topic and kind of get uh kind of get back on track here how about that pause the soups for just a second hey kyle this is my first live stream well then i apologize for that here we go everyone donating for extra microphone technology i honestly don't know what it was um that's usually not an issue it was an issue when i tested anyway this is a beautiful freshwater lake in fact it is the largest freshwater lake by volume um you've probably seen images of this uh this lake in siberia it's named lake baikal it contains 20 to 30 percent of all of the earth's surface fresh water in one lake and if you've been on the internet for any amount of time i'm sure you've seen images of this lake floating around with the methane bubbles frozen and it's crystal clear ice it's an absolutely uh fantastic it's it's a wonder of nature methane bubbles is crinsing exactly uh and uh it's absolutely beautiful but it's not just beautiful for its sight it's also beautiful for its sound so uh a news story that uh made some headlines in the siberian times which i always and without fail read was a photographer who uh skated his little skates out on like by cal here away from all the tourist areas and what he did is recorded with a high-end sound equipment the sounds that the lake was making as it was cracking beneath his skates um he amplified that sound and slowed it down so you could hear with your uh stupid human tympanic membranes someone someone said hey you look like stupid aquaman i'm trying my best at least i'm not under water you wouldn't be able to hear me at all anyway so he recorded this amplified it slowed it down and it sounds just like laser beams this ice cracking and i wanted to highlight that because i know exactly why this is and i can even show you and all i need is a slinky so let's get right to it this is what he recorded and showed us now listen to this pretty crazy right now i hope everyone got to hear exactly what that sounds like um it's very very cool obviously and what is happening here what's making this pew pew sound it's called dispersion so when um just like waves of pressure just like light can travel at relatively speaking different speeds through different mediums sound the frequencies of sound can travel at different speeds through something like ice to the point where it's separated by even frequency so high frequency and low frequency sounds can travel at different speeds through this ice now more specifically because of this dispersion this this de-linking of high and low frequency you're not hearing the same all the frequencies of once you're hearing them separated because of the um because of the ice what's happening with this dispersion is that you are as as the frequencies separate you end up hearing the high frequencies before the low frequencies and so what you get in uh in aggregate is a u and when it happens quickly say like almost instantaneous cracking you can get like pew and i will demonstrate this to you and you can do this at home especially uh you elizabeth with your tiny human you can do this at home you don't even need any special equipment all you need is a slinky and a nice rigid piece of paper here like i have now what i'm going to use the paper for is i'm going to sandwich it in the slinky and it's going to be kind of my amplification system you can do this also with say a styrofoam cup you just wedge it in but it's somewhere for the frequencies to go and to be transmitted out into the air effectively such that you can hear them so consider this like my telephone but it's just a piece of paper so what i'm going to do is i'm going to hold this at the end and try not to touch the slinky too much with my hands because i don't want the vibrations to go into my body my body vibrates enough as it is so i'm going to hold this like this and then i'm going to hold this up to the microphone and all i'm going to do is i'm going to move the slinky and if i'm right about the science here which i am you're going to hear the same exact pew-pew noise here we go how cool is that get it right up close to the microphone hear that so i can probably even make this amplification a little bit better here if i cone it up a little bit see that and all you need is a piece of rigid paper and a slinky so um you can also see this effect not only in the ice you can see it uh skipping stones across a frozen lake i've seen this in deep ice bore holes dropping something like a rock down a uh very long borehole and what and now you know the answer is dispersion you don't really need to know the term that's not what's important what's important is that as the sound waves travel back up or back around the medium the frequencies are separated such that you hear the high and then the low the p and then the u and that's how you get that and that's how you make the largest freshwater lake by volume in the world not just look beautiful but sound beautiful too do you know what else sounds beautiful my audio this stream you won't know why i'm saying that if you're watching this not live because i cut out the part where i messed up for 10 whole minutes sally says i'm gonna go buy a slinky i it's one of the oldest toys bobby finger says did you know that anderson cooper is directly related to the vanderbilt family okay mr diglett as always supporting us at the facility with the 20 something for signs sheryl sanders with the five says hey kyle love the show wink well cheryl um thank you from a science teacher for doing what you do keep it up well thank you cheryl for being a science teacher for being on the front lines of educating our youth about stem uh about the importance of being curious and uh and and valuing knowledge and exploration of the mind um i can only do what i do because i stand upon the shoulders of giants such as yourself who are actually molding and shaping the young minds so i appreciate you cheryl thank you so much for doing what you're doing teachers do not get enough appreciation especially in the united states ariel with the 20 says hey kyle love the show and the x-men cartoons mystique is showing is showing turning herself into a small raven and then flying away how strong would she have to be to fly if her mass stays the same yeah there is a hard mass limit on flight you can see this in well as i'm sure you're aware because you're all nerds birds have a lot of evolutionary adaptations to make flight more possible most notably i'm sure you know something like hollow bones so just from the evolution of burns you know that mass is going to be a serious problem so there is a kind of a hard mass limit on how big birds can get um and that is well below the mass of the average human person now i say that because a ravens wings because a modern bird's wings are so small relative to us they don't have only a few birds have giant wingspans and even when they do they're still not heavier than us so a mystique turning into a small raven if she still had the body mass of say 65 kilograms or something like that it would she would not have enough muscle mass in her wings to keep her flying that's not to say that more massive creatures can't fly the quetzal quetzalcoatlus the largest winged thing to ever fly was like 20 feet tall and enormous but it also had enormous musculature and physiology so that's how it made it possible if you're really small you don't have a whole lot of wingspan you just do not have the thrust there you need to be bigger um justin cho with the 10 says if teleportation worked the way it did in star wars oh star trek sorry oh yeah how embarrassed am i would you step into a teleporter to join me for korean barbecue here in seoul um so you're saying if a transporter kills me and then i am reborn on the other side just an exact copy of myself would i subject myself to that kind of disassembly just to come to korea south korea and meet you in seoul for some korean barbecue absolutely yes i would i want to go to korea so bad you may have seen i did an interview with one of my favorite uh bedroom uh music artists uh soo lee and suli is a fantastic artist i like her a lot and she lives in seoul and uh i want to visit there so bad and i was watching a bunch of starcraft tournaments and then uh youtube started giving me a bunch of visit korea uh vacation style commercials from like the tourist board and it looks so fun and i used to live in in uh in china so i'm familiar with the the area of the world so i'd love to i'd love to come back cameron with the 25 says hey kyle never get to watch live because i a truck because i'm a trucker great first one great first one right yeah i'm glad that you spent your trucking time watching me trucking up so to speak uh love the shows keep it the good work science rules indeed it does my man camphor with the with the 10 says technical ebert technician ebert from temper oh no i'm gonna have to call security technician ebert from temporal mechanics here please stop using the time machine to play magic the gathering with yourself my assistant got swallowed by a paradox and now i'm the only person that remembers them yeah you know who i am yeah level five ebert temporal mechanics yeah he's about 56 kilograms i don't think it'll be too hard to throw him into the into the paradox vortex well i don't even know i don't even want to know who he is in the past love you should be fine resolved it will be resolved soon uh lots of super chats i think everyone's feeling bad for me because uh i messed up a full 10 minutes of the stream which i guess i need means i need to go for a full 10 minutes longer that's fine farrell beast with the 25 says kyle we regret to inform you that your application for membership has been denied ah while we believe you're incredibly smart and the best looking hemsworth objectively not true you are a terrible villain sincerely the lee the evil league of evil tom hanks why would i be talking about tom hanks right now well good question why would i be talking about tom hanks as well as kovid at the same time you might say well part one of today's partial themes is that of science communication and there is a new study out that looked at the impact of tom hanks talking about covid19 in relation to people's thoughts and feelings about kovid19 and i will say don't worry you can keep those super chats coming uh soon because i have a couple of short topics here but i wanted to highlight an interesting effect so there was a study recently that concluded something like this this suggests that public health officials and advocates may want to use these types of celebrity announcements to help reach people who them who may be harder to reach what this study was concluding was showing that a everyone knows who tom hanks is and b because everyone knows who tom hanks was when tom hanks said that he got covet in uh the first two weeks of march 2020. because everyone knows tom hanks and likes tom hanks it actually changed their attitudes towards the severity of the pandemic and the situation and this is that i've cat hair everywhere this is interesting to note because i mean it's interesting but it's not surprising right so this compared to something like an advisement from the cdc tom hanks reaches a lot more people with more weight it seems like which again it's not surprising but there's whenever i talk about science communication especially with people in academia there's all always this tension between seeming very expert and being very public there you watch me so this is gonna this might sound like something like a surprise but there's a lot of old school people in academia right now that view science communication the kind of stuff that i do every day as frivolous wasting your time why do that there are young professors and i know many of them who are looked down upon for practicing the public engagement of science now you have that attitude and now you have findings like this that say well if you want to try to get your message across people aren't going to listen to you as much in all circumstances you may view yourself as very academic very expert the be-all end-all voice on something something or not but but wilson and his very hairy friend can make more of an impact on your public health goals than you can and so i see a very natural push and pull here that should be incorporated into more public awareness public health plans if i was trying to get the word out about some kind of public health initiative enlisting celebrities and public personas to get scientific information out there is not diminishing the importance of the science you're saying i feel like a lot of academics may think that but stuff like this proves that tom hanks can have more of an impact than you ever dreamed of just writing up a press release and sending out to places where no one will actually see it right and we've known about this kind of effect for a long time uh there's a story going around recently that that um a few decades ago elvis went on was it johnny carson another giant tv show at the time he went on a giant tv show at a time and got a vaccination live on television and it changed attitudes around the country around the world instantaneously because everyone loves elvis and he was saying this thing is okay this thing is safe just imagine the public good that could be done today for again for example if tom hanks also went on t went on you know every late night tv show or whatever and showed a clip of him getting a vaccination said like you know i took it seriously and so i did it and i hope you do it too that would have such an impact right and so when i get my vaccination i haven't been vaccinated yet but i have been tested for covin multiple times i have not gotten it yet um but when i get my vaccination i will let people know that i did because i do not agree with the old academic stance of you know keep science very ivory tower kind of stuff we gotta relate to people and how do you relate to people sometimes with tom hanks's academy award-winning performances it's obvious we have angie with the 10 says i love your show and look forward to your videos every week thank you so much well thank you so much angie um as i was saying on various on patreon and and stuff like that um i'm trying to do one of my half-life histories per month because i love doing them now and they do well um but this week i'm at an impasse let me know because the only video i have to put out because a bunch of things are held up for different reasons the only thing i have to put out is another one of my mini documentaries and i don't want to like waste it or publish a new one too soon i don't know what should i do you can let me felix chabot with the canadian ten dollars he says hey kyle great show you got there pretty much the only live stream i watch well thank you we know you have a choice in live stream so we appreciate your business here on kyle air hillaire prince of hill i usually don't simp but i can do an exception for science well i love to hear that uh lavish uh livia's gameplay says if they don't take the opportunity to off the diabolical kyle hill whilst he takes his vasc vaccine that won't do it to us exactly it would be a great opportunity to deal with let's say a hypothetical super villain and if i'm fine afterwards you know it's fine for you i mean all these vaccines are in like that over 90 efficacy rate with the same amount of uh the same uh the same rate of side effects as a regular vaccine which is like the really bad side effects are like one in a million and so when you're trying trying to save like hundreds of thousands of lives the math is really easy on that you know vanilla waffle just says simping yeah that's what we're doing um michael strauss with the five says kyle love the science stay for the hair can you talk about gfx video re-up movie and vacuum balloons how could we reach this with current technology i have no idea what you're doing oh okay okay okay regarding up and vacuum balloons how could we reach this um i think i once calculated that it would take it's either i forget the order of magnitude it's either ten thousand large balloons or a hundred thousand large balloons to lift the house from up other than that i don't know what you're talking about thank you um elizabeth again with the five says on bbc one in an interview hank said the naughtiest thing he ever did at work was drink cartons of chocolate milk working as a dishwasher what a what a what a what a stupendous man side note if you want a good recovery drink doing a big workout or something like that chocolate milk goes a long way uh combat medic combat medic 25 says if antimatter were to collide with a black hole what would happen would some of the black hole get cancelled out well see the interesting well black hole a black hole isn't really a mass it's not really a sphere of stuff it's not like a like a neutron star for example it is a singularity in space time it is an ultimate collapse down a gravitational well and so if you threw antimatter at a black hole it doesn't really have something to touch so to speak but that reminds me antimatter bombs would not be as easy as you think like a photon torpedo simply because anti-matter would react with any kind of matter and so if you would go step by step you imagine an antimatter hunk hitting some kind of surface the instant the very instant it hits some surface this is going to create a tremendous annihilation event right here and that will explode in all directions spherically and so if there's not a target all the way around what's going to happen is that when this front end explodes it's gonna it's going to push this target away and damage this target but it's also going to push the rest of the mass of the bomb away and so with with a tremendous amount of energy being released i mean an anti-matter bomb could be something like and that would incredibly decrease the yield of the bomb it would be very inefficient you'd have to go to uh more lengths than you think you would have to go to to make an anti-matter bomb uh very efficient but i'm sure the federation thought of that oh i'm fine master of all with a 12 uh master of all again as always with the australian ten dollars says hey kai i agree with you that consciousness is made entirely in the brain but if you were disassembled and reassembled wouldn't you still be dead and someone just like you would be living instead philosophical question if you died if you were disassembled and reassembled would you still be you this is a philosophical question i've answered it before on stream um that if something is a down to the quantum state copy of me it has to be me if if i know the the energy and position of every single possible particle and state that my body could possibly be in in this universe then a copy of that would have to be me there's no other there's the what i'm trying to get at is that if you could fully capture the information of a person because i believe everything that makes you you is could be captured in the scientific information so to speak of that person and if i copied you and disassembled the original there is no other option than for that to be you there's no room left for selfness there's no immaterial kyle if i created a perfect copy of me down to the quantum level it wouldn't need a pinch of immaterial kyle that you know like a greek god like sparks them to life or something like that okay i'll give you a gift but i'm of the opinion that you wouldn't need anything else if you could if you could completely copy yourself and so yes it would be you for all intents and purposes i thought the saying was for all intensive purposes for the first 25 years of my life let's get to some of you uh in the chat who are not simping because they're supporting you preston smith says i don't think teleportation will ever work i don't think we're ever gonna get to that level of technology either um not at least before we destroy ourselves quinn mooney says okay so hypothetically a near perfect pressure chamber would still have some matter inside if you could suspend a perfect sphere of antimatter inside in a near vacuum never mind too few words so there's ideas on how to contain a hunk of antimatter that we already have and we've already tried to do you can contain it magnetically for example because antimatter still has a charge it's matter with the opposite charge in fact you could contain it with magnetic fields electromagnetic fields rather and you could suspend it in a perfect vacuum such that it doesn't touch anything and it doesn't go anywhere you can do that but you need a perfect vacuum or so close to a perfect vacuum that you know only single atoms are going to hit it and it won't really make a difference over regular amounts of time but you yes you you can confine it you just have to get clever with a near perfect vacuum ign says hello wow you had a shot and you missed who can name all these people right now these are all science communicators this is the chin of richard dawkins that's that's old carl this is i mean they're not this show isn't a science communication show but it's the kind of show that people who love science uh like too much okay that's not fair i also like rick and morty but there's a lot of people who like rick and morty and science who like aren't cool you know they like harass fast food workers and stuff but these are all scientific and yep kirk is that uh yeah no i yeah i'm not on why why not why aren't i on this because i'm talking about science communicators so um someone in my discord recently uh tam who's often in the chat here on youtube sent me a science communication paper in our uh educators channel on discord and i like to look at science communication papers because i believe that if we are to get better at getting out technical information to everyone the democratization of information and knowledge we should as with anything reflect on what we do see what works see what doesn't work and this paper was specifically about youtube excuse me and science communication on youtube so of course i was interested and this is a paper in germany i believe and they looked at 400 different science videos and they categorized them into a couple different categories obviously sorry from videos that are uh animation style like kurzgazat here to videos that are narrative present uh narrative presentation style like old tv shows like cosmos and a few other categories and what they were trying to do is see what style and what medium of communication was most effective at getting people to retain information afterwards and also they looked at where people's eyes were going with eye tracking technology to see what their what people were actually focusing on and i just wanted to touch on this briefly because it was interesting to me um this is one of this is an expert an expert an excerpt from the paper and this stood out to me because it says something very interesting that i don't think science communicators and and people uh like all of yourselves who like talking about science and science and things i think this is something that we don't think about and here there's a there's a potential landmine here hidden in this information and i'm not i'm never gonna forget this now because one uh hi guy chan says love from israel love from not israel that's the logical opposite of israel that's where i am um meaning that i'm i can't tell you where i'm anyway um so this landmine in science communication that i'm talking about is highlighted here and it's as follows the more entertaining of video is rated the stronger the belief that the content represented is correct and stronger the trust in the authors this corresponds to an effect called the illusion of understanding or the easiness effect simplification for example via infotainment as as it's called prompts the recipients to assess the content easier and more trustable and to overrate their epistemic understanding the results of the study contradict the assumption that youtube users dissociate science from entertainment so what this is saying is counter to what you may think or what we may perceive an audience or you at home to think that science and entertainment can be so intertwined that it can change the perception of the information that the entertainment value of a science video separate from technical information can make you think that technical information is more trustworthy or not now that's not surprising but it is as i said a land mine it is dangerous and it's something that i'm going to keep in mind going forward why because and i have a lot i'm not going to i'm not going to name names but i do have a lot of problems with science some science communication on youtube specifically because the ease for example a very flashy animated video on youtube can can give you a false sense of understanding the topic at hand and so what i'm always trying to do in my work speaking personally is as einstein said make everything as simple as possible but not simpler and it's never crossed my mind that by increasing the entertainment value or trying to i might be falsely inflating your perception of understanding of the topic for example i would not want it to be the case that i made a video about quantum mechanics and i may and quantum mechanics seemed easy to you because the video is so entertaining there is no one in the world who thinks quantum mechanics is easy and if they say that they do they're probably just you know what kind of person says that i mean like richard feynman a literal genius you know his famous quote is if you think you understand quantum mechanics you don't but what i'm getting at is is that i would always want to be very cognizant of am i brushing over too much am i am i trying to flatten over this this this this hurdle of of mental difficulty with entertainment value is is that because i don't understand it do i want to make someone else feel like they understand this more than i do is that an effect that i could impress upon them if so then that is disingenuous and that's really really interesting to me because now uh cause sorry i'm reading what you're saying um because i feel like i have a duty to all of you to impress upon you some kind of understanding but i don't want to make you i don't want it to ever feel like something that is genuinely hard is too easy or easier than it seems or less complicated than it seems so there's this tension where i i want to take highly technical information and make it digestible and entertaining at the same time i don't want to make it seem like fuel that kind of mindset where it's like well i'll just google it and i probably know all that i need to know no i mean there's a reason people go to school and stuff so it's rocked my world a little bit because i think the people who do it the best are doing it the right way you know carl for example can speak in a way that gives a kind of wit and lyricism and and wonder to the world without diminishing it without making it smaller without reducing the mysteries of the world just to atoms and molecules and then the on the other hand you know you have dozens and dozens of youtube channels that are just like animations and infographics that are three minutes and 23 seconds long and they have 10 million views and the information they're in is either fully copied from other places and it's presented poorly or it's presented poorly and the information is poor you see him i see him i i'm not i don't think all science communication is good you know in any field there's going to be most of it is going to be crap you know these are good examples but there's going to be someone keep in mind and i want you and i'm kind of rambling here but i don't care i want you to keep this in mind as well when you're very entertained by a video you're like wow this videos it looks great it's really good i'm engaged ask yourself do you do you ask yourself afterwards did you retain that information do you really felt feel like you learned something or were you just being passively entertained were you being engaged and maybe that's one of the ways you can judge quality going forward interesting red run red rum or murder murder with the 10 says awesome live stream kyle my awesome daughter thinks you're awesome and i think you're awesome too it would be awesome if you'd awesomely give an awesome shout out to awesome hayley you're welcome hayley i think you're awesome you know what i think you're probably more awesome than a giant hunk of ice hurtling through the solar system and you won't see it until you're much what i'm trying to say is you're cooler than a comet haley and you know that now earn it i'm sorry we talked about tom hanks way so i had saving private ryan on the brain haley you're awesome don't let anyone tell you that you're not and if they do tell them to go kick rocks kevin do kids say that anymore really you're 75 you shut up he doesn't support me in anything that i do deep scorn says everything is awesome that's not true most things aren't by definition most things aren't awesome i'm not a happy-go-lucky guy words have meaning to me and if everything's awesome then nothing's awesome if everyone is beautiful then nobody's beautiful you know what i mean it's like this i don't know it's a flattening of culture and language like everything is good everyone is awesome everybody's nice that's not true let's be real you can grow up i'm i think i'm a little rowdy i'm a little excited a little excited today i probably need to calm down a little bit it's because you don't know this youtube but uh the opening of the stream did not go well absolute zero with the australian 10 says hey kyle love the show i've always had an interest in science and history it's people like you that make those things all the more interesting keep on doing what you do thank you so much speaking of science and history we have i think i think we'll publish the new mini documentary this week and uh my editor just texted me about 10 minutes before we went live and they said um wow this episode is really messed up like like like true crime documentary messed up i was like i love that i love to hear it i can't wait for you to see it it's pretty weird but weird in like a real way elliott with the five says hey kyle love the love why do you do this why why do i subject me i'm finishing my bachelor's of science in physics and engineering is that a single major whatever in physics and engineering and i'm thinking about getting a master's degree of some sort should i get a job first um i i wish i could help you out with this i don't know um i because i did i never worked as an engineer i went uh i got my engineering degree i took the uh fundamentals of engineering exam i passed i could have gone on to start working in the industry um but instead i stayed at school and i went on to get a master's degree uh in science communication who would have thought so i never worked as an engineer um so it's hard for me to give you that advice i would guess again talk to other people who actually have experience but i would guess that it would really depend on where you want to be do you want to be working as an engineer do you want to be doing you know the kind of like the day-to-day boots on the ground kind of stuff or do you want to pursue more academic um routes do you want to be a professor do you want to teach do you want to be a professor do you want to research and be in academia then you know grad school is probably the better idea but if you want to get working now and start you know making airplanes and cool stuff like that depends i depend again i don't know like your choi like if you want to go into like you know aeronautics maybe they need a master's degree from you before they hire you at more than an entry level position i don't know i don't know everything i just know a little bit about a lot of stuff except for plants i don't know much about plants it's a blind spot parker brilliant oh what a cool name parker brilliant private eye he solves mysteries smartly parker gonna try to make feel kyle better after his evil league rejection shout out to adam savage's shout out to kyle on his recent videos love the show yeah if you didn't watch it um if you want to know the origin of uh adam savage's famous phrase i reject your reality and substitute my own he recently published a video on the tested youtube channel and in the first 10 seconds of that video he says well i'm telling you this because uh kyle hill texted me at 2am and asked me now i'm not gonna show you this but i didn't just text i sent him a video of me in a bathrobe because i'm fancy and i was like and i was looking at him i was looking at where i thought the quote was from and it was in my face and i went hey hey dude it was 2 am hey dude is this where you got this from then i turn the t i turn the phone turns it towards the tv and i turn it back and then i texted him at two in the morning not thinking that he's a man with a family who's probably sleeping and so that's and then the video was born what a good person i am nick duney with the australian 1499 dollar says hey kyle do you have a lot of australian sims love it is it because i look australian just because i look this way doesn't mean i boogie board hey kyle do you think we could use the iss as an anchor point to build a space elevator i think it would reduce the cost of space exploration in the long run um the real issue with so the mathematics of a space elevator are known we know how long the tether would have to be we know how heavy the mass would have to be um we know at what point if you climbed along the tether into space you'd be completely weightless we know though those maths as uh the english would say the problem is that think of spinning a rock on the end of the string the faster you spin it and the heavier the rock the more tension's on the string right it's harder to spin it the earth is spinning at a thousand miles an hour and the international space station is very heavy it's so heavy in fact that any design for a space elevator right now there's no material that we know of on earth that is strong enough to handle the tension the stress there not even carbon nanotubes so the real problem with the space elevator is the material strength of the teller of the of the elevator of the tether itself that's a problem it's not a theoretical problem it's a practical problem well i guess it's both in it uh so why don't we pause the super chat for a second because we're almost out of time i know i'm gonna go a little bit later because i messed up well let's see what you have to say on the last episode at the facility look i'm tiny now so uh this is peer review peer review and as i want to do every week i take a comment from the latest episode of the facility that made me go hey how wow or wow i'm super wrong and i highlight it i show it all to you we all acknowledge the brilliance of this one commenter and then they get an honorary membership to the facility and they get a plaque from kevin who definitely has it this time can't confirm so my uh on the last episode at the facility we're talking about the unstoppability of a super intelligent ai and what we're going through was the problem with the so-called halting problem and analogous to the halting problem is the question could we use a computer or computer science or an algorithm or a program whatever can we use any one of those things to go into a super ai and check if it had any evil programs running around so to speak and because and you can watch the video because it's analogous to the halting problem this problem of going into an ai and making sure every program is great this problem is fundamentally undecidable so we can never ever be sure using a computer that another computer is fully under our intentions and that's the problem and in relation to that jam yang pelsang said this one issue with super intelligent ai misinterpreting our commands is that sometimes we ourselves don't truly understand our own commands in the case of maximizing human happiness we ourselves don't actually have a complete understanding of what makes us happy ain't that the truth happiness has been a philosophically complicated subject throughout the entire history of philosophy therefore without humanity itself not fully comprehending what happiness is or really what any of humanity's collective goals or desires are super intelligent ai cannot fully comprehend it either why would it it would require a very complex list of moral constraints on the methods to achieve certain objectives where we as a species still to this day have no clear consensus on that forces our commands to be incredibly precise and undermines the value of super intelligent ai handling large-scale problems in the first place the limits of controlling super intelligent ai are dependent upon the limits of human language and its function in communicating our wants and needs wow jam yang you could have probably just written the whole script that i used myself and i think you're completely right what you're what you're talking about is what we said in the video and what computer science is called perverse instantiation we don't even fully understand what we mean when we say make us happy so how could a how could we possibly put that into ones and zeros and make a computer fully understand that um one of the examples we said was what if you say to a super intelligent ai you know come up with a plan to maximize human happiness and what it does is it enslaves humanity connects every single person up to a vat of serotonin and dopamine and waits and and and just waits until they die in their sleep in a happy coma that oh there's a there's a cardboard cutout on me behind me that wouldn't be against its goals as directed so if we can't even understand our own intentions all the time or our own goals all the time how could a super intelligent ai ever do so and the problem is that a super intelligent ai could be so much more efficient and actionable in what it wanted to do if it wanted to take over the planet it probably could figure out a way to do so better than any general better than any human in existence so that's the scary part and that's kind of what i was trying to get at we need to solve this problem we need to decide what this problem is now before it is fundamentally undecidable as i said and for pointing all this out jam yang palsy you are now an honorary member of the facility and kevin is going to get you a plaque right now and i hope this phone call i'm getting is unrelated to that hello everything's fine i'll be right back [Music] [Music] that wasn't weird at all and you can't prove that it was balthazard with the canadian 35 dollarenos could you review the book the revolutionary phenotype thanks sure just let me read it first book recommendation a revolutionary phenotype what i'm reading right now it's not around here anymore i'm reading right now um the plutonium files by eileen wilson um who wrote a hewlett surprise winning series of articles about secret plutonium injection experiments on human beings and that may or may not have something to do with the topic of the next mini documentary who my editor texted me during that commercial break and said wow this is like it's right out of a movie i can't wait to show it to you it's gonna be good we have simon spencer with the five says kyle would this still hold with quantum programming where it would simultaneously solve every possible answer well that depends if the super intelligent ai is a is a quantum computer um but i guess at some level of computation it doesn't really matter right i mean if the super intelligent ai is so so smart so good so advanced it doesn't super matter that it's not quantum because it can arbitrarily compute anything like that anyway you know what's the difference between this and this to us nothing you know uh we have jesus skywalker with the australian ten dollars let me read it to make sure it's not terrible i understand the that's not australian i understand the fear that we have that we have on creating ascension ai that might enslave us and that's where the conversation always goes but do you have any thoughts on creating essential ai that would be a scent that would essentially have enslaved what wait wait wait but do you have any thoughts on creating a sentient ai that we would have essentially enslaved ourselves um well i kind of i kind of got to that right if if a super intelligent ai isn't allowed to really do everything it's capable of doing if it's physically contained it has no connections to the internet it can't send or receive signals it's not plugged into anything um then it it's arguably useless it as as i also said you know if it's so so smart it could it has a potential to convince anyone of anything um and so if you don't let any humans near it if it can't communicate with any other machine it's effectively like not having one at all that would be like an enslaved super intelligent ai but then why have that you know there's no point henry henry with the 999 says hey hey love kyle the show i was wondering what you think about perpetual motion devices producing energy much love from new jersey um perpetual motion devices are not a thing why because it presumes that you can get some amount of energy you can get a 100 of the energy you put into something so you know say something tumbling in space i flick it and it would go absolutely forever and i could get some energy out of that for example something like that now people wanted this to be true forever because it would mean free energy and it would revolutionize society the problem is there's no such thing as a free lunch in the universe there is anytime systems interact systems always tend towards more disorder than order and thermodynamically speaking because of that nothing is 100 efficient no work in the physics sense of the word is 100 efficient there's always some loss in friction sound heat deformation something and because of that you are never going to be able to get a machine a perpetual energy perpetual motion device nothing could move forever without eventually stopping yes it could be 99.99999 efficient it could it could the ultimate fidget spinner in the universe could spin for whatever the heck it is 20 years or whatever but because it would even in space it'd still be hitting tiny particles you know there's one hydrogen atom per cubic centimeter there's still stuff in space and because of internal friction it would eventually slow down and eventually stop things can get really really good but they're never going to be perpetual because that's just not the way thermodynamics works it's not the way the universe works and for anyone you're seeing a video if you're seeing claims that they've created something like this they are literally saying that the laws of the universe can be broken that they have broken them and that no one else has ever thought of that kind of thing before ask yourself when you hear those claims what are the chances that the laws of the universe have been suspended and in your favor what are the chances of that compared to you don't really fully understand what you're talking about and i find that usually the people who think they've come up with some kind of perpetual motion device have not gone to school and do not have doc doctorates and mostly just read wikipedia is that is that shocking to you you know i mean it's a one-to-one correlation isn't it it seems like the level of knowledge to the number of perpetual motion devices you think you can make is like nicely like perfectly inverse right you have a lot of knowledge you're like that's not possible you have a little bit of knowledge maybe you have no knowledge oh the government killed tesla i'm taking shots today i don't know why i'm doing that but perpetual motion devices aren't a thing ian with the 10 says we can't figure out what makes us happy but why couldn't an ai more intelligent than us ourselves figure that out how why couldn't figure out how to make a meat machine happy and that is that's not that's not actually the problem the problem is that it could figure out how to make us happy but it's interpreting happy by itself so like i said it could logically determine that most humans have some amount of suffering in their lives and the only way to completely alleviate all human suffering forever one uh one possible interpretation of be happy no human suffering in the universe ever for all time would be to just eliminate all the humans that's one logical interpretation and because that is one logical interpretation that's the problem what if it decides to enact that interpretation well if it's not even possible to tell whether or not it will do that that's the problem with creating the super intelligent ai in the first place we can't be sure what it's going to do because we cannot program human intent but we can put humans intense funnily enough and uh closing like we usually do let's go back to my labs real quick okay closing like we usually do we have music central piano 29 with a 5123 who says as always keep up the great work kyle the science communication topic was very informative science is not a set of facts but the methodology that establishes those facts laws theories etc good communicators spark interest in the process of understanding i could not have said it better myself music central piano thank you all i thank you all especially you you all who uh started from the beginning of the stream because no one on youtube is going to see what we all went through collectively it was pretty rough i almost had an on-screen breakdown where i got really hot and like flustered but that didn't happen so thank you for all of you stuck by me thank you uh to everyone who was simping today at the facility look if you want to continue on this conversation after the stream is done you can go to patreon.com kyle hill as my security team is putting in the chat right now i mostly lurk but i also talk to you and we can play magic the gathering sometimes we went through a number of topics today this week on the facility like i said i don't have any other videos to publish because of complicated reasons aside from my next mini documentary so i think i might have to do that just to stay consistent so that i don't be consumed by the algorithm so look forward to that my editor says it's like straight out of a movie and it's really effed up their words so look forward to that uh have a wonderful rest of your week what day is it where am i it's tuesday and until i see you next time please please please be nice to each other in here online in person wear a mask socially isolate yourself whenever possible and be nice to each other because this is all we got
