As a molecular biologist, I always find it funny that nano-technology and bio-technology are considered two different things. Biology is the best example of nanotechnology we have today. Our cells consist of literally hundreds of thousands of gene products, thousands of different types of molecules, and most importantly, a massively information-dense architecture. Not the typical "DNA is digital" hoopla. DNA is a molecule in which one aspect can be compressed into an ordered sequence of A, G, C, T nucleotides. But it is a molecule, a big one, and how it interacts with other molecules is at the crux of its information density. Moreover, computational networks exist as the cell itself, not just DNA. Regardless, biologists use nanotech all the time, we just call it biology. Polymerase chain reaction is an example. We create a reaction of DNA polymerases, buffered salts, nucleotides, small DNA primers (~20 nucleotides long), and DNA templates. Combined with the correct application of periodic heating at three temperatures we generate a reaction that exponentially copies some DNA target. The RNA vaccine uses a lipid to enter cells. In the lab, we use this molecule mostly to get some desired RNA or DNA into cells for experimentation. This technique is ubiquitous nowadays. These lipids literally form into a sphere that encapsulates the DNA or RNA in solution. We then add this mixture to a plate of cells and this transfects the cell, beginning a process that ends in the breakdown of the lipid spheres and the release of the RNA/DNA into the cell. The DNA is then transported into the nucleus and a whole new round of nanomachines processes it in different ways. I'll stop there but there are thousands of techniques that use various organic molecules and proteins to perform some process which we can use to measure something, or produce some other molecules, or capture some molecules, etc.
I was quite surprised he didnt mention liposomes and even CRISPR, particularly since liposome delivery is the breakthrough that made MRNA vaccines work
Exactly. Nanotech has been around for billions of years. I think human nano tech would realistically look a lot like biology. When you get to that scale, mechanical engineering isn't practical, you need chemical engineering. Self replication is a lot easier too. If you can grow and divide then you're sorted. Machines as we know them cannot really do either. Maybe it can slice itself in two but without growth it each generation will get smaller and smaller. As wildly complex and intricate as cellular chemistry is, in principle its a lot easier to grow something which is essentially just a bubble of goo wrapped in lipids. Our tech will probably just be highly modified microbes. I say "will be".. but as you pointed out, in many ways we're doing it now.
@Alien Demonic Deception 24 they'd just put it in the cornflakes m8, Again. What logic would there be to pointing it out to the public . Besides covid-19 is looking more and more like a Putin plot everyday. Be glad for a defense.
This video just gave me more motivation to study harder. I'm currently taking classes in nanotechnology and similar subjects, so to think that in 2-3 years I could be working on something as amazing as making limbs for amputees or making little robots that remove cancer is so uplifting. Thanks for the motivation!❤️
Brian Beeswax No way they`ll tell us what`s REALLY going on. Remember Smart Dust? Where did THAT go? We`re all probably already robots for China and don`t know it yet.
In 1972, MIT predicted widespread societal collapse around 2040. With a few decades behind to use as a metric, an int'l accounting firm revisited it, and found we were right on track. You can forget about nanos, robots, AI. We're headed towards the iron age.
@@inthso362 I’ll try to find this myself but if you happen to have a link to this, that would be nice. General predictions of doom are a dime a dozen, so I’d like to see if they get into any specifics
I remember some years back when a tech company said they'd invented solar power paint. Once dry the surface generated electricity like a solar power panel. I thought back then that if it could integrated into clothing you could have a windbreaker that charged your phone. What ever happened with that stuff? I know this is off-topic but if I don't write down a thought right away I will soon forget it. Damaged. So it goes.
There are a variety of these "paints" in development. The first demonstrable prototypes only reach 5% efficiency though, compared to 14% for the "solar brick/tile/shingle" also on the market now. Supplemental reduction/"greening" only. However - "A popular testing choice, CIGS-perovskite tandem cells have made big gains, from 17.8 % efficiency in late 2016 to 21.5 % in January 2019. And since CIGS thin-film is already successful at scale, improving the tandem performance of perovskite may be easier than working alone on the new technology. It is also not out of the question to pair Perovskite with silicon. IMEC researchers believe a silicon-perovskite stacked cell could easily push an efficiency of 30 %." thesolarlabs.com/ros/solar-paint/
It exist. Forget what it is called, but I remember reading an article that states this solar paint was capable of making Hydrogen energy with sunlight and water
@@defaultlogos2976 While it has been long enough for me to have forgotten the technical details, the idea itself is both interesting and promising. The field of possible applications is wide indeed. (Thank you very much! I was beginning to doubt my own memory.)
Also a big thank you for the Curiosity Stream plug -- I signed up at the low rate you mentioned, and have been loving all the content I can now access. Thanks Joe!
I really appreciated that segment on the fungus-treated wood flooring producing electricity simply by people standing or walking on it. I've been asking for a couple decades now why we can't have piezoelectric roads and parking lots, for the exact same reason they made that flooring: there is a LOT of free energy that could be generated.
Well, that energy isn't free per se. You're leeching it from cars and people who pay for gas and food. It's never generated for free, only transferred from somewhere. Now if these are ways to improve existing efficiency of transference without affecting the efficiency of other systems, that would be more ethical and essentially be the "free" energy you're looking for.
These are my favourite kinds of videos. I really love getting updates on tech we first heard about years ago and have had advancements that perhaps wouldn’t necessarily garner a lot of media attention. Nanotech, Graphene, 3D printing etc.
Regardless that you can find an in depth documentary about the topics you cover I would argue that a 15 min sum-up definitely has its place. Keep up the good work Joe. For me AWJ is something I always look forward to and enjoy watching very much.
It was the realization that viruses and bacteria were already capable of doing essentially all of the things that medical nanotechnology was supposed to do that made me become a microbiologist. Seriously, they are sub micron in size, have chemical sensors, motors, and can replicate from in situ resources as simple as water, sunlight, and carbon dioxide, and nitrogen gas.
Very true. Bacteria and viruses are much more useful tools, because of what Jeffrey said. Who would want to rely on abiotic, metallic nanobots with a host of unknown complications/side-effects when you can hijack the naturally evolved roles and mechanisms of existent lifeforms?
There is the possibility that tech replaces biology only to turn back to biology as the best overall evolution. Pros and cons and the circle of life that this universe has as a fundamental property.
Oh, man! I nearly squealed when I saw the title for this video. I'm currently doing my Master's Degree on Nanotech, and listening to Joe explain some of the things I hear about everyday is just so exciting! Thanks for the education you bring, Joe.
@@joescott You totally did! Very well informed. The effort you put into your videos is clearly noticed. Obviously there's A LOT you could not possibly cover in a single video, Nanotech has a very varied range of applications, but you covered it in general terms, love it.
well hopefully you can join the future for nanotech and get that charge creating fungal material into shoe insoles that can charge our smart devices as we walk.
@@daemenoth look, I don't want to jump the line here, but if we're taking requests: how about some of those nanobots that go inside us and fix everything? I'd appreciate it
@@MarcillaSmith i'm pretty sure a full charge on my smart phone is more important than public health.... what is the point of being in good health and alive if your phone is dead lol
I think about this daily. The fact that all my wildest dreams will become daily norm, only long after I'm gone, causes me no end of depression... My deepest, truest desires, the few things that _really_ matter to me, the changes that would make me _truly_ content and happy to exist... are perfectly possible, just not today.
@Fixxitt 412 @Wallung Dea @Puck Do you guys think millenials will catch the tech to become immortal? Well, really long lived. Born in the 90s... Too early? Or.... juuuuuuuuuuuust right?
Personally I take the optimistic view of this. We may have incredible advances in medical technology within just a few decades. Maybe not the stuff I'm truly excited for yet, but possibly just enough to expand our lifespans to reach those things.
Hi Joe, we like your videos and use them for homeschool- long time subscribers. We just joined Curiosity Stream under your link to also help support you further. Please keep the great videos coming, and thank you for not dropping F-bombs constantly, talking about bizarre sexual acts or other things we don't typically include our homeschool day. Keep the quality content coming; your dry sense of humor is appreciated!
If you limit education to people who happen to express emotion more severely by cursing you're doing a disservice to your children. Learning to set apart differences in ideals to communicate and benefit from others you disagree with on some things, but do agree with on others is an important thing to learn in such a polarizing time. The earlier a kid learns to be uphold ideals of their own despite what others do the better off they will be in the age of social media. Limiting exposure is setting them up for being totally unprepared when they aren't under your guidance and your degree of influence on them will end earlier than you expect.
@@n111254789 Yeah Jack, you took me way too extremely. I appreciate your thoughts. I'd still rather keep the wild stuff my kid sees in the format of things like "Venture Brothers" and perhaps not from his educators. Thanks again for your input.
I've been studying Nanosciences for nearly 3 years now. Its amazing do see, what is possible with Nano and also seeing things humanity or nature have been doing forever that actually are Nanotec as well. On the other hand advancing the science to get the really cool futuristic stuff is hard as nails. And expensive, really expensive.
@@bluewater454 Yeah, also many non toxic things can become toxic, once they are manufactured at the right size enabling interaction with biological stuff. But I would say with Nukes, Virus-editing capabilities and similar advances already "on the market" current nanotechnology is not really the threat we need to take most seriously. There is already plenty of other options around to express your evil. Once our monkey-brains have evolved enough to move past concepts like mutually assured destruction, then we may rack our brains about the threat of nanomachines, which may be bad, but is also decades from being reality. Recently read Prey by Micheal Crichton. While it points out some real concerns, tech like that is not going to happen soon or suddenly.
Surprised at no mention of Drexler. He was the person who introduced me to the idea nanotechnology, and got me sincerely interested in transhumanism as something possible within my lifetime when I was a teenager in the late 90's. I wrote my senior english class research paper on nanotechnology, mostly referencing him. I know he's kind of not respected anymore, due to not having practical ideas. But I don't think it can be argued that he wasn't a very influential figure, who spurred a lot of interest and energy into the development of nanotechnology.
Nanophotonics is where the fun stuff is at. Something really cool to point out that nano materials tend to be at the same size of visible light and that can crate some really cool interactions. One thing I was hoping you’d talk about are Hyperbolic-metamaterials but they’re super recent.
I've been watching Joe's channel for 8 or so years now, and I honestly think he's one of the best TH-camrs out there... I think its crazy some idiots have 10 and 13 million subscribers, and he has under 1.5 only... But yea, the world is a weird place... Love you Joe!
appealing to the lowest common dominator, means you have a crap ton of exposure to the lowest common denominator. in other words, those people who have millions of followers usually have low quality fans who are either toxic, idiotic. i'm not saying that has to be the case, however i do think that after a certain point of growth, it really doesn't matter to people. i'd rather have a good quality of people, than a large amount of people.
Another researcher/writer to look into on nanotechnology is Eric Drexler. He wrote the book "Engines of Creation" (1986.) Going into a detailed discussion on nanotechnology in terms that's understandable to the average person (highly recommend.)
11:00 regarding nanotechnology and cancer - we're still at caveman level. Let me explain: Virtually every biomedical intervention relies on the circulatory system to deliver the thing to where it needs to be. Whether it be cancer cells in the brain or pain relief in a limb. This means that, over time, whatever you are wanting to put into [highly specific area of interest], will end up everywhere else as well. I'll give you an example case: Patient is a 15 year old male who has recently suffered a catastrophic impact with a tree while down-hill skiing. The patient presents with shock and a broken limb: the tibia has broken into two pieces, which have become disconnected. The patient is placed under medically induced coma for medical intervention - the bone is realigned, screws are put in place, and the incision is closed. The patient is weened off of the anesthetic and should recover within the hour. 2 hours later the patient is still not recovering. The attending physician is shocked - the patient is at risk of brain damage! The attending is referred to the hospital neurosurgeon due to this being a brain circulatory issue - there is no clear reason why any of the drugs are at fault, the patient has no known allergies and nothing popped up in family screening. The neurosurgeon has seen just 2 such cases in his lifetime, having worked in a much larger hospital, and immediately recommends an x-ray of... The chest? The tibia is broken, the problem is clearly in the brain, and yet mr. Neurosurgeon wants to order an x-ray of the chest. Weird. X-ray comes back with something strange. The patient's lungs seem to have a polka dot pattern. Lots of small dots littering the chest. What's going on? The dots are fatty acids and, with a course of medication, quickly disappear into the bloodstream. The patient awakes. No brain damage. Discharged the following day. Okay what happened? When the patient's tibia broke, this exposed the blood marrow to the circulation. Fatty acids from the blood marrow seeped into the blood and went everywhere, including the brain and lungs. During the operation the patient was given blood thinners and other medications, which caused the fatty acids to get everywhere. After these were discontinued, the fatty acids then coagulated in the vasculature of the brain. Now, you don't x-ray the brain for fatty acids, because they won't show up. The entire brain has lots of fluids and has a consistency more of fat than lean muscle, is suspended in a sac of water, and so on. So you x-ray the chest, which has a large volume which gives a very nice contrast. Also, lots of vasculature, so higher numbers of "polka dots". Any nanotechnology has to wrestle with this problem. We even administer pain medication based on BMI for this reason - because BMI is highly correlated (though not perfectly, so we don't ONLY use BMI) with your blood volume, which in turn is highly correlated with the amount of blood circulation. We want a specific dose / blood volume, in very basic, non-medical terms. We are still at 10,000 BC technology level when it comes to medicines. .. Now if you want to talk progress, I warmly recommend hitting up the topic of "intraoperative (or interventional) MRI", "intraoperative Ultrasound", "stereotactic surgery", "image-guided surgery" and "minimally-invasive surgery". I would like you to contrast these topics with things like lobotomy, just to get an idea of how far we've come. The topics above could be simplified to: "Brain surgery - from an ineloquent to the eloquent brain".
For a couple of pretty entertaining treatments of the Grey Goo phenomenon, may I recommend later seasons of Stargate: SGI, and the second season of Lexx.
another good point solids versus hollows ... a paper with holes cut out is almost as string but stacked the holed one is stronger relative to its weight
Some very cool things on the show today. I hadn't seen the nano animation before, so thanks for that, Joe. I wonder if we will ever get to pushing and pulling things around at the Plank constant limit? If we built a nano machine that could build even smaller devices to get very small, just rinse and repeat until small enough. Electron manipulation is certainly getting there!
I think the real trick is designing the "next smaller" machine once we approach the size of simple molecules functioning as complex machine. How do you program a single atom? I'm personally very excited for where this field of science is heading.
The biggest problem people overlook is the strength of “nano” machines. At those scales, binding energy’s in molecules far outstrip the energy capacity of an individual nano scale machine. Likely we will rely on a combination of chemistry principles and atomic scale 3d printing to produce our nano machines. Nano machines are highly unlikely to be able to disassemble materials due to binding strength. So they won’t be much use for complex building projects either.
I’m a chemist and my field of research is gold nanoparticles as nanovaccines aganist cancer. Loce this video so much, I hope more people discover the opportunities has to offer.
Glad you mentioned dangers, but why not mention soda, sun screen, food dyes, etc? Or how many non- fda approved nano products enter our markeplace each week? You should do a crossover on nanotech and aging, btw
It’s the “theoretical limit” so once we’re there in technology we will have the freedom to think about it more practically. I mean *in theory* we could find a way to manipulate Quantum Fluctuations that make up Atoms at the sub-atomic scale that work as transistors, etc.
For those who are interested in this end of technology you might want to have a look at a company called Integran Technologies. I was honored to have a tour of their facility and see some of what they have done and what they can do. They have a very large list of prestigious clients with a wide variety of applications. As a nerd, it gives me the "Warm Fuzzies "when I think about what they do. They mostly into material coatings.
Always look forward these videos. I wonder what's next... Astroid detection? Geothermal science? Lasers? Future tech? Love it all. Keep up the good work team.
Important note about transistors is that once we hit a gate length of ~30nm, the node name no longer reflected any physical measurement of the transistor, so a "5nm" transistor is "5nm planar equivalent" roughly. As in, we have used FinFETs to scale transistors beyond what planar transistors could achieve and so although we still have transistors with physical measurements between 20-30nm, the performance and density of these transistors are roughly equivalent to a 5nm planar transistor.
Science fiction writers: "not sure how to get out of this corner I have written myself into." Friend: "you struggling to come up with an ending?" Writer: "no, I can't decide whether to use 'nano thing' or 'quantum thing'...."
Powering stadiums or dance clubs (or at least extra bits like lights and such) with the floor would be a great idea. It would also be awesome if they could harness the crowd energy from cheers, whistling, applause, etc.
The problem with nanotechnology in computers is that it might not be small enough! We need a whole new way to manipulate matter at even smaller scales than the nanometer because we're already at the limit of what nanotech can do in computers. Edit: aaaand Joe just narrated me typing this comment 😆
Well - my students do build materials up atomic layer by atomic layer in labs, using graphene and some of its many “family relatives” - just like Feynman predicted. Also, a modern iphone is packed with many kinds of bona fide nanotechnology. Is iPhone a practical application? I would say it is.
Every door in every building should be spring loaded, self closing equipped and linked to a dynamo. We're some of the the most efficient generators at our disposal.
I used to act on Japanese TV on the side for supplement income and I had a few jobs with a woman from Russia who was using acting to supplement her own income while she studied there in Tokyo. She was studying nanotechnology at a university, and it leads me to a useful suggestion for future videos: A note about how those of us interested in the field can get into it. Where should we study? How do we get into these fields? I’ve become bored of my 18 years in the video-game industry and haven’t worked in over a year while I try to find what else interests me and where my future should point, and when you present a video like this it makes me dream of new horizons!
Ooo my field. The part about unexpected health effect made me a bit Anxious... considering ho much nano stuff I have handled as unexperienced student in stil pinioning phase :D Made my Master thesis on quantum dot. Phd on Nanostructured organic semiconductors. Also made some sortie on carbon nanotubes. Most for Photovoltaic application but also on sensors, catalyst and metamaterials. So participated in this slow, hard but steady revolution from 2007 to 2017 before changing sector.
11:52 onwards: "The Grey Goo Effect" reminds me of the episode of Futurama where Bender clones into smaller and smaller duplicates, eventually entering the water stream etc.. ☺
@@joescott That would be a cool one to watch! You have to tell some of his funny stories that he relays in his book: "What Do You Care What Other People Think?": Further Adventures of a Curious Character
Joe, regarding transistors at 5:45. They have not gone down to 5nm in size, but roughly 30-50nm in size (differ between manufacturing company). The name "5nm" is only a process node, the name for how transistors are made and is different between each company (TSMC vs Samsung vs Intel, etc).
The funny thing about the electricity generating floor tiles is that it's not free energy, you're actually making the people walking around expend more energy working against the sponginess of the tiles. It's the start of the Matrix.
We already walk around on spongy surfaces though since we need to cushion our footfalls to avoid damaging our feet and wearing out the floor, the former is solved by our padded feet and padded footwear and the latter by floor coverings like carpet or linoleum. Also energy-providing surfaces are not noticeably spongy so they would be imperceptible from a regular floor covering.
The best way to visualize scale of ANYTHING is to go look up the demo "Scale of the Universe 2". It let's you slide along a logarithmic scale down from the planck length all the way to the size of the observable universe. When I saw it 10-ish years ago it totally changed my understanding of scale.
Just a little joke: Back in college a group of friends and I would make the joke: "Carbon nano tubes are really [freakin'] light. But photon nano tubes are REALLY [freakin'] LIGHT!"
So Where Exactly Are We With Nanotechnology? Well Joe, half of the country doesn't think vaccines do anything, so we have a long long long way to go before we can even start talking about nano technology.
Lol why do you think they are so eager to get EVERYONE injected with a non long term tested vaccine? Trying to bypass individual choice and body autonomy in the process. Their reasoning for wanting to have everyone vaccinated just doesn't hold water when natural immunity has been shown as superior. Thus one has to wonder why politicians are their pharmaceutical handlers are trying to rewrite known medical science & protocol. Either it's purely for the big universally mandated payday (at the expense of the tax payer) or there could other more insidious reasons.
Wellp I am fully vaccinated and got the variant of covid I was supposed to be mostly immune to. It didn't reduce symptoms and I was in the hospital for nearly a month pretty healthy fella too I race dirt bikes and shoot basketball. Don't smoke, don't drink, no drugs, only issues I got are depression and my appendix and gallbladder had to be removed. The vaccine was rushed and no one should deny that as it was admitted to being rushed and it is only allowed to be distributed due to special circumstances granted by the fda. This isn't a normal development cycle and it didn't work for me and two others I know personally so blindly supporting something so new is a bad idea and the long term effects is unknown. What I've stated so far are facts. Essentially calling someone who is skeptical ignorant doesn't work in a lot of cases this being one of them.
There’s a company in Canada that has developed non toxic gold nano rods that can target specific cells and proteins. They apparently want to use them for targeted drug delivery, photo thermal imaging, photo thermal tumour therapy. Looking forward to seeing what they do with their tech. I think their smallest particle is 600nm.
The pandemic came and taught everyone the importance of having multiple stream of income, unfortunately having a nice paying job doesn't mean you are financial secured anymore. So we all need to put in an etra-income earning chance, like investment.

My favorite way to illustrate the scale of the prefix "nano" is with the speed of light. In one second, light travels about 186,282 miles (299,792 km). That's 7.5 times around the Earth in one second. In one NANOsecond, light travels about 12 inches (30 cm). Mind=blown.
Starting at around 8:43, you'll want to replay the next 10 or 15 seconds in very slow motion so as to appreciate the "scale" of thinking that went into all those Fishy TV show titles.
1:09 First time in a while situation where I might say LOL describing my reaction, while actually laughing aloud rather than just saying it. Thank you for that, sir.
As someone who’s put a lot of thought into creating electricity from the process of walking I’ve come to realize that it’s not as great as it might seem. The problem is the deflection of the surface you’re walking on will actually fatigue the walker, you’re essentially stealing the energy from the human that’s walking to create it.
Joe, besides "Cool Worlds " , you're one of my favorite channels. I used to watch Veratasium, but have shyed away due to not aligning with his business philosophy. Thanks Joe
Nanoelectromechanical systems, or “NEM’s” and MEM’s are really exiting, many of these systems are physical in nature rather than electronic and serve manufacturing purposes like accelerometers with physical systems like a flexing structure that will only complete a circuit under acceleration, or literal gears and levers to perform any number of potential mechanical actions, they are made by lasering pre treated silicon, the same way that microchips are made which allows new designs to be truly nano in scale. one team of researchers even managed to build a MEMs device that could capture and insert drugs of choice into individual blood cells and the device was only about twice the size of the blood cell, which is amazing, frankly.
As for toxicity-answer comes in two forms. A-Since nano bots can target specific areas of the body they can theoretically break down any harm they are causing. B-we can use other materials like synthetic biologically friendly ones that won’t cause damage in the first place… which we have already seen with CGMs and other pods implants
Talking about, your videos be so consistently well done all the time. Don't know how you do it or how you keep doing it, but good job. . . .and, yes. You are correct. That WAS a lot of nouns and adjectives.
JOE, I'm surprised that you NEVER mentioned K. Eric Drexler's name even once, which imo is a MAJOR faux pas, since he is widely conceded to be nanotechnology’s “founding father"! While Feynman simply posited the idea of building at this scale, using the example of a complete full-scale machine shop used to make another smaller machine shop, which makes another smaller machine shop, etc. until you eventually arrive at a molecular scale machine shop, but he did not come anywhere close to going into great depth on expanding the theory. K. Eric Drexler was inspired in 1979 by reading Feynman's 1959 presentation ,"There's Plenty of Room at the Bottom" which led him to change his course studies, which was no small feat since almost NONE of the teaching professors understood nor agreed with him. But he eventually found a mentor and Drexler's 1981 graduating thesis paper, “Molecular engineering,” was the result and was published in the Proceedings of the National Academy of Sciences - this ESTABLISHED THE FUNDAMENTAL PRINCIPLES of molecular design, protein engineering, and productive nanosystems. In accomplishing this, Eric Drexler was the VERY FIRST to receive a Ph.D. in the field (at MIT), where he also went on to teach the first course in nanoscience (as well as at Stanford) and also chaired the first two conferences on the subject. Btw, while Prof. Taniguchi was the first to use the term "nanotechnology", it was widely unnoticed and it took Drexler's "co-discovery" and expansion of the term into "molecular nanotechnology" for it to gain a foothold in the scientific community, which he codified with his early work in the field There's SOOOO MUCH MORE to know about Eric Drexler, but anyone who's interested in the AMAZING THEORIES that Drexler posited and just how much of his early predictions are, or are close to, becoming reality, I highly recommend starting with his 1986 book ENGINES OF CREATION: The Coming Era of Nanotechnology, which proposed everything from amazing new nano-materials to the idea of a nanoscale "assembler" which would be able to build a copy of itself, aka the self-replicating nanobot (and he also coined the term "grey goo" that you used). SADLY (and imo this is a stain on the scientific community) the ideas he presented seemed so strange and unsupported by scientific proof, that he was widely ridiculed with a rare vehemence by many scientists and so spent years wandering the wilderness, as it were, until enough work had been done as to validate Drexler's earlier ideas. So it is only in recent years that he's received the praise and acknowledgement that he was denied, and imo he should receive A NOBEL PRIZE in engineering, material science and more for his work. But as this video shows, K. Eric Drexler is STILL ignored and his contributions forgotten by most people, smh :?(
Joe, can you do a video on time zones? Specifically, when mankind realized that different locations had different local times, and what caused the creation of time zones?
Ralated Topic : The PROTEIN FOLDING problem. I would love to see a Joe Scott breakdown of this. Anyone else? I first heard of it in 2003 as a CS major in college and was fascinated back then, and it has had some recent break-throughs in recent years, I think.

There's a novel by Michael Crichton called 'Prey' and it's literally about a 'gray goo' scenario where things get out of hand to say the least. Yeah, the concept is pretty scary because in my opinion, it's more plausible than AI turning against humanity. Or aliens invading. Just a machine doing its job.
Given this perspective on nanometer scale, let's think about the fact that the current generation of AMD's AM4 CPU architecture is built on a 7nm transistor platform. That means that each transistor is 1,000 smaller than the thickness of a red blood cell. And that's the generation that's on it's way out...🤯
What about String/M Theory? There was a "Golden Age" where Brian Greene and Michio Kaku were everywhere, popping out books & shows left, right, up, down, charmed, and strange and then somebody found the God Particle and then... Nothing. No progress since. No Greene or Kaku anywhere for years now, at least from a content perspective (unless I missed something). Not even a sitcom starring Greene, Kaku, and Neil deGrasse Tyson as dysfunctional roomies.
good question ... what does it weigh ... shrinking means same relative weight at scale ... so it will not collapse the ground .. the ground actually exerts no effort once you stop moving ... the speed will be 60km/h at scale .. so whatever a km/h is at the scale of the shrunken craft
I’m familiar with the concept of Nanotechnology. It was a child-like enemy then an ally in the 2003 Teenage Mutant Ninja Turtles, a health bar/healing system in the Ratchet and Clank video games, and of course, a fearsome weapon in the 007 James Bond movie No Time To Die. Science and technology can be good, it can be bad, it ultimately depends on how we choose to use it.
This answers a question I didn’t know I had.

"Nanomachines son they harden in response to physical trama... you can't hurt me jack"
As a molecular biologist, I always find it funny that nano-technology and bio-technology are considered two different things. Biology is the best example of nanotechnology we have today. Our cells consist of literally hundreds of thousands of gene products, thousands of different types of molecules, and most importantly, a massively information-dense architecture. Not the typical "DNA is digital" hoopla. DNA is a molecule in which one aspect can be compressed into an ordered sequence of A, G, C, T nucleotides. But it is a molecule, a big one, and how it interacts with other molecules is at the crux of its information density. Moreover, computational networks exist as the cell itself, not just DNA.
Regardless, biologists use nanotech all the time, we just call it biology. Polymerase chain reaction is an example. We create a reaction of DNA polymerases, buffered salts, nucleotides, small DNA primers (~20 nucleotides long), and DNA templates. Combined with the correct application of periodic heating at three temperatures we generate a reaction that exponentially copies some DNA target.
The RNA vaccine uses a lipid to enter cells. In the lab, we use this molecule mostly to get some desired RNA or DNA into cells for experimentation. This technique is ubiquitous nowadays. These lipids literally form into a sphere that encapsulates the DNA or RNA in solution. We then add this mixture to a plate of cells and this transfects the cell, beginning a process that ends in the breakdown of the lipid spheres and the release of the RNA/DNA into the cell. The DNA is then transported into the nucleus and a whole new round of nanomachines processes it in different ways.
I'll stop there but there are thousands of techniques that use various organic molecules and proteins to perform some process which we can use to measure something, or produce some other molecules, or capture some molecules, etc.
As a chemical engineer I fully agree.
I was quite surprised he didnt mention liposomes and even CRISPR, particularly since liposome delivery is the breakthrough that made MRNA vaccines work
Exactly. Nanotech has been around for billions of years. I think human nano tech would realistically look a lot like biology. When you get to that scale, mechanical engineering isn't practical, you need chemical engineering. Self replication is a lot easier too. If you can grow and divide then you're sorted. Machines as we know them cannot really do either. Maybe it can slice itself in two but without growth it each generation will get smaller and smaller. As wildly complex and intricate as cellular chemistry is, in principle its a lot easier to grow something which is essentially just a bubble of goo wrapped in lipids. Our tech will probably just be highly modified microbes. I say "will be".. but as you pointed out, in many ways we're doing it now.
@Alien Demonic Deception 24 they'd just put it in the cornflakes m8, Again. What logic would there be to pointing it out to the public . Besides covid-19 is looking more and more like a Putin plot everyday. Be glad for a defense.
Uneducated numbskull here... I love how bacteriophage look like engineered machines.
This video just gave me more motivation to study harder. I'm currently taking classes in nanotechnology and similar subjects, so to think that in 2-3 years I could be working on something as amazing as making limbs for amputees or making little robots that remove cancer is so uplifting. Thanks for the motivation!❤️

In 1972, MIT predicted widespread societal collapse around 2040. With a few decades behind to use as a metric, an int'l accounting firm revisited it, and found we were right on track.

I remember some years back when a tech company said they'd invented solar power paint. Once dry the surface generated electricity like a solar power panel. I thought back then that if it could integrated into clothing you could have a windbreaker that charged your phone. What ever happened with that stuff? I know this is off-topic but if I don't write down a thought right away I will soon forget it. Damaged. So it goes.
yeah, I remember something of the sort. Then nothing. I guess it didn't work out for some reason...?
There are a variety of these "paints" in development.
The first demonstrable prototypes only reach 5% efficiency though, compared to 14% for the "solar brick/tile/shingle" also on the market now.
Supplemental reduction/"greening" only.
However -
"A popular testing choice, CIGS-perovskite tandem cells have made big gains, from 17.8 % efficiency in late 2016 to 21.5 % in January 2019. And since CIGS thin-film is already successful at scale, improving the tandem performance of perovskite may be easier than working alone on the new technology. It is also not out of the question to pair Perovskite with silicon. IMEC researchers believe a silicon-perovskite stacked cell could easily push an efficiency of 30 %."

I really appreciated that segment on the fungus-treated wood flooring producing electricity simply by people standing or walking on it. I've been asking for a couple decades now why we can't have piezoelectric roads and parking lots, for the exact same reason they made that flooring: there is a LOT of free energy that could be generated.
Well, that energy isn't free per se. You're leeching it from cars and people who pay for gas and food. It's never generated for free, only transferred from somewhere.
Now if these are ways to improve existing efficiency of transference without affecting the efficiency of other systems, that would be more ethical and essentially be the "free" energy you're looking for.
These are my favourite kinds of videos. I really love getting updates on tech we first heard about years ago and have had advancements that perhaps wouldn’t necessarily garner a lot of media attention. Nanotech, Graphene, 3D printing etc.
Regardless that you can find an in depth documentary about the topics you cover I would argue that a 15 min sum-up definitely has its place. Keep up the good work Joe. For me AWJ is something I always look forward to and enjoy watching very much.
It was the realization that viruses and bacteria were already capable of doing essentially all of the things that medical nanotechnology was supposed to do that made me become a microbiologist.
Seriously, they are sub micron in size, have chemical sensors, motors, and can replicate from in situ resources as simple as water, sunlight, and carbon dioxide, and nitrogen gas.
Very true. Bacteria and viruses are much more useful tools, because of what Jeffrey said. Who would want to rely on abiotic, metallic nanobots with a host of unknown complications/side-effects when you can hijack the naturally evolved roles and mechanisms of existent lifeforms?
Awesome!

I think about this daily. The fact that all my wildest dreams will become daily norm, only long after I'm gone, causes me no end of depression...
My deepest, truest desires, the few things that _really_ matter to me, the changes that would make me _truly_ content and happy to exist... are perfectly possible, just not today.

Hi Joe, we like your videos and use them for homeschool- long time subscribers.
We just joined Curiosity Stream under your link to also help support you further.
Please keep the great videos coming, and thank you for not dropping F-bombs constantly, talking about bizarre sexual acts or other things we don't typically include our homeschool day. Keep the quality content coming; your dry sense of humor is appreciated!
If you limit education to people who happen to express emotion more severely by cursing you're doing a disservice to your children. Learning to set apart differences in ideals to communicate and benefit from others you disagree with on some things, but do agree with on others is an important thing to learn in such a polarizing time. The earlier a kid learns to be uphold ideals of their own despite what others do the better off they will be in the age of social media. Limiting exposure is setting them up for being totally unprepared when they aren't under your guidance and your degree of influence on them will end earlier than you expect.
@@n111254789 Yeah Jack, you took me way too extremely. I appreciate your thoughts. I'd still rather keep the wild stuff my kid sees in the format of things like "Venture Brothers" and perhaps not from his educators. Thanks again for your input.
I've been studying Nanosciences for nearly 3 years now. Its amazing do see, what is possible with Nano and also seeing things humanity or nature have been doing forever that actually are Nanotec as well. On the other hand advancing the science to get the really cool futuristic stuff is hard as nails. And expensive, really expensive.
It’s also scary as hell. So much potential for evil.
@@bluewater454 Yeah, also many non toxic things can become toxic, once they are manufactured at the right size enabling interaction with biological stuff. But I would say with Nukes, Virus-editing capabilities and similar advances already "on the market" current nanotechnology is not really the threat we need to take most seriously. There is already plenty of other options around to express your evil. Once our monkey-brains have evolved enough to move past concepts like mutually assured destruction, then we may rack our brains about the threat of nanomachines, which may be bad, but is also decades from being reality. Recently read Prey by Micheal Crichton. While it points out some real concerns, tech like that is not going to happen soon or suddenly.
Surprised at no mention of Drexler. He was the person who introduced me to the idea nanotechnology, and got me sincerely interested in transhumanism as something possible within my lifetime when I was a teenager in the late 90's. I wrote my senior english class research paper on nanotechnology, mostly referencing him. I know he's kind of not respected anymore, due to not having practical ideas. But I don't think it can be argued that he wasn't a very influential figure, who spurred a lot of interest and energy into the development of nanotechnology.
Nanophotonics is where the fun stuff is at. Something really cool to point out that nano materials tend to be at the same size of visible light and that can crate some really cool interactions. One thing I was hoping you’d talk about are Hyperbolic-metamaterials but they’re super recent.

appealing to the lowest common dominator, means you have a crap ton of exposure to the lowest common denominator. in other words, those people who have millions of followers usually have low quality fans who are either toxic, idiotic. i'm not saying that has to be the case, however i do think that after a certain point of growth, it really doesn't matter to people. i'd rather have a good quality of people, than a large amount of people.
Best channel on TH-cam. Thank you Joe for the consistent compelling content.
That's too kind, thank you. :)
Another researcher/writer to look into on nanotechnology is Eric Drexler. He wrote the book "Engines of Creation" (1986.) Going into a detailed discussion on nanotechnology in terms that's understandable to the average person (highly recommend.)
11:00 regarding nanotechnology and cancer - we're still at caveman level.
Let me explain:
Virtually every biomedical intervention relies on the circulatory system to deliver the thing to where it needs to be. Whether it be cancer cells in the brain or pain relief in a limb. This means that, over time, whatever you are wanting to put into [highly specific area of interest], will end up everywhere else as well.
I'll give you an example case:
Patient is a 15 year old male who has recently suffered a catastrophic impact with a tree while down-hill skiing. The patient presents with shock and a broken limb: the tibia has broken into two pieces, which have become disconnected. The patient is placed under medically induced coma for medical intervention - the bone is realigned, screws are put in place, and the incision is closed.
The patient is weened off of the anesthetic and should recover within the hour.
2 hours later the patient is still not recovering. The attending physician is shocked - the patient is at risk of brain damage!
The attending is referred to the hospital neurosurgeon due to this being a brain circulatory issue - there is no clear reason why any of the drugs are at fault, the patient has no known allergies and nothing popped up in family screening.
The neurosurgeon has seen just 2 such cases in his lifetime, having worked in a much larger hospital, and immediately recommends an x-ray of... The chest?
The tibia is broken, the problem is clearly in the brain, and yet mr. Neurosurgeon wants to order an x-ray of the chest. Weird.
X-ray comes back with something strange. The patient's lungs seem to have a polka dot pattern. Lots of small dots littering the chest. What's going on? The dots are fatty acids and, with a course of medication, quickly disappear into the bloodstream.
The patient awakes. No brain damage. Discharged the following day.
Okay what happened?
When the patient's tibia broke, this exposed the blood marrow to the circulation. Fatty acids from the blood marrow seeped into the blood and went everywhere, including the brain and lungs. During the operation the patient was given blood thinners and other medications, which caused the fatty acids to get everywhere. After these were discontinued, the fatty acids then coagulated in the vasculature of the brain.
Now, you don't x-ray the brain for fatty acids, because they won't show up. The entire brain has lots of fluids and has a consistency more of fat than lean muscle, is suspended in a sac of water, and so on. So you x-ray the chest, which has a large volume which gives a very nice contrast. Also, lots of vasculature, so higher numbers of "polka dots".
Any nanotechnology has to wrestle with this problem. We even administer pain medication based on BMI for this reason - because BMI is highly correlated (though not perfectly, so we don't ONLY use BMI) with your blood volume, which in turn is highly correlated with the amount of blood circulation. We want a specific dose / blood volume, in very basic, non-medical terms.
We are still at 10,000 BC technology level when it comes to medicines.
.. Now if you want to talk progress, I warmly recommend hitting up the topic of "intraoperative (or interventional) MRI", "intraoperative Ultrasound", "stereotactic surgery", "image-guided surgery" and "minimally-invasive surgery".
I would like you to contrast these topics with things like lobotomy, just to get an idea of how far we've come.
The topics above could be simplified to:
"Brain surgery - from an ineloquent to the eloquent brain".
I read it all. You should write like this as a script.
I've seen several videos of this Asian American explaining medical cases, this reminded me about those.

Some very cool things on the show today. I hadn't seen the nano animation before, so thanks for that, Joe.
I wonder if we will ever get to pushing and pulling things around at the Plank constant limit?
If we built a nano machine that could build even smaller devices to get very small, just rinse and repeat until small enough. Electron manipulation is certainly getting there!
I think the real trick is designing the "next smaller" machine once we approach the size of simple molecules functioning as complex machine. How do you program a single atom? I'm personally very excited for where this field of science is heading.
Go further...what if you could create mechanical properties using only wave energy. That is life.
The biggest problem people overlook is the strength of “nano” machines.
At those scales, binding energy’s in molecules far outstrip the energy capacity of an individual nano scale machine.
Likely we will rely on a combination of chemistry principles and atomic scale 3d printing to produce our nano machines. Nano machines are highly unlikely to be able to disassemble materials due to binding strength. So they won’t be much use for complex building projects either.
We need to start building with the fabric of space/time itself

It’s the “theoretical limit” so once we’re there in technology we will have the freedom to think about it more practically.

They made an android female whose buttocks could undulate. I don't remember the details, but I'm pretty sure it was this timeline.
Important note about transistors is that once we hit a gate length of ~30nm, the node name no longer reflected any physical measurement of the transistor, so a "5nm" transistor is "5nm planar equivalent" roughly. As in, we have used FinFETs to scale transistors beyond what planar transistors could achieve and so although we still have transistors with physical measurements between 20-30nm, the performance and density of these transistors are roughly equivalent to a 5nm planar transistor.

Powering stadiums or dance clubs (or at least extra bits like lights and such) with the floor would be a great idea. It would also be awesome if they could harness the crowd energy from cheers, whistling, applause, etc.
The problem with nanotechnology in computers is that it might not be small enough!
We need a whole new way to manipulate matter at even smaller scales than the nanometer because we're already at the limit of what nanotech can do in computers.

The funny thing about the electricity generating floor tiles is that it's not free energy, you're actually making the people walking around expend more energy working against the sponginess of the tiles. It's the start of the Matrix.
Might not be free energy, but it's a decent way to get back some energy from work that wouldn't be used other than in walking lol
We already walk around on spongy surfaces though since we need to cushion our footfalls to avoid damaging our feet and wearing out the floor, the former is solved by our padded feet and padded footwear and the latter by floor coverings like carpet or linoleum. Also energy-providing surfaces are not noticeably spongy so they would be imperceptible from a regular floor covering.
The best way to visualize scale of ANYTHING is to go look up the demo "Scale of the Universe 2". It let's you slide along a logarithmic scale down from the planck length all the way to the size of the observable universe. When I saw it 10-ish years ago it totally changed my understanding of scale.

@@michaelquinlan2121 oooooh spooky
Lol why do you think they are so eager to get EVERYONE injected with a non long term tested vaccine?
Trying to bypass individual choice and body autonomy in the process.
Their reasoning for wanting to have everyone vaccinated just doesn't hold water when natural immunity has been shown as superior.
Thus one has to wonder why politicians are their pharmaceutical handlers are trying to rewrite known medical science & protocol.
Either it's purely for the big universally mandated payday (at the expense of the tax payer) or there could other more insidious reasons.
Wellp I am fully vaccinated and got the variant of covid I was supposed to be mostly immune to. It didn't reduce symptoms and I was in the hospital for nearly a month pretty healthy fella too I race dirt bikes and shoot basketball. Don't smoke, don't drink, no drugs, only issues I got are depression and my appendix and gallbladder had to be removed. The vaccine was rushed and no one should deny that as it was admitted to being rushed and it is only allowed to be distributed due to special circumstances granted by the fda. This isn't a normal development cycle and it didn't work for me and two others I know personally so blindly supporting something so new is a bad idea and the long term effects is unknown. What I've stated so far are facts. Essentially calling someone who is skeptical ignorant doesn't work in a lot of cases this being one of them.
And nanotechnology already exists and is being developed so we can and have been talking about it for decades now.
There’s a company in Canada that has developed non toxic gold nano rods that can target specific cells and proteins. They apparently want to use them for targeted drug delivery, photo thermal imaging, photo thermal tumour therapy. Looking forward to seeing what they do with their tech. I think their smallest particle is 600nm.

My favorite way to illustrate the scale of the prefix "nano" is with the speed of light. In one second, light travels about 186,282 miles (299,792 km). That's 7.5 times around the Earth in one second. In one NANOsecond, light travels about 12 inches (30 cm). Mind=blown.

As someone who’s put a lot of thought into creating electricity from the process of walking I’ve come to realize that it’s not as great as it might seem. The problem is the deflection of the surface you’re walking on will actually fatigue the walker, you’re essentially stealing the energy from the human that’s walking to create it.

Nanoelectromechanical systems, or “NEM’s” and MEM’s are really exiting, many of these systems are physical in nature rather than electronic and serve manufacturing purposes like accelerometers with physical systems like a flexing structure that will only complete a circuit under acceleration, or literal gears and levers to perform any number of potential mechanical actions, they are made by lasering pre treated silicon, the same way that microchips are made which allows new designs to be truly nano in scale.
one team of researchers even managed to build a MEMs device that could capture and insert drugs of choice into individual blood cells and the device was only about twice the size of the blood cell, which is amazing, frankly.
Bruce Banner: Where'd that come from?!
Tony Stark: It's nanotech. You like it?

As for toxicity-answer comes in two forms. A-Since nano bots can target specific areas of the body they can theoretically break down any harm they are causing. B-we can use other materials like synthetic biologically friendly ones that won’t cause damage in the first place… which we have already seen with CGMs and other pods implants
0:15 Literally that exact scene came to mind, nice.
Talking about, your videos be so consistently well done all the time. Don't know how you do it or how you keep doing it, but good job.
. . .and, yes. You are correct. That WAS a lot of nouns and adjectives.
Nano tech and harvesting are two words that just feel creepy and wrong when used in the same sentence.
Let’s speed up all this research and put it into practice
JOE, I'm surprised that you NEVER mentioned K. Eric Drexler's name even once, which imo is a MAJOR faux pas, since he is widely conceded to be nanotechnology’s “founding father"! While Feynman simply posited the idea of building at this scale, using the example of a complete full-scale machine shop used to make another smaller machine shop, which makes another smaller machine shop, etc. until you eventually arrive at a molecular scale machine shop, but he did not come anywhere close to going into great depth on expanding the theory.
K. Eric Drexler was inspired in 1979 by reading Feynman's 1959 presentation ,"There's Plenty of Room at the Bottom" which led him to change his course studies, which was no small feat since almost NONE of the teaching professors understood nor agreed with him. But he eventually found a mentor and Drexler's 1981 graduating thesis paper, “Molecular engineering,” was the result and was published in the Proceedings of the National Academy of Sciences - this ESTABLISHED THE FUNDAMENTAL PRINCIPLES of molecular design, protein engineering, and productive nanosystems. In accomplishing this, Eric Drexler was the VERY FIRST to receive a Ph.D. in the field (at MIT), where he also went on to teach the first course in nanoscience (as well as at Stanford) and also chaired the first two conferences on the subject.
Btw, while Prof. Taniguchi was the first to use the term "nanotechnology", it was widely unnoticed and it took Drexler's "co-discovery" and expansion of the term into "molecular nanotechnology" for it to gain a foothold in the scientific community, which he codified with his early work in the field
There's SOOOO MUCH MORE to know about Eric Drexler, but anyone who's interested in the AMAZING THEORIES that Drexler posited and just how much of his early predictions are, or are close to, becoming reality, I highly recommend starting with his 1986 book ENGINES OF CREATION: The Coming Era of Nanotechnology, which proposed everything from amazing new nano-materials to the idea of a nanoscale "assembler" which would be able to build a copy of itself, aka the self-replicating nanobot (and he also coined the term "grey goo" that you used).
SADLY (and imo this is a stain on the scientific community) the ideas he presented seemed so strange and unsupported by scientific proof, that he was widely ridiculed with a rare vehemence by many scientists and so spent years wandering the wilderness, as it were, until enough work had been done as to validate Drexler's earlier ideas. So it is only in recent years that he's received the praise and acknowledgement that he was denied, and imo he should receive A NOBEL PRIZE in engineering, material science and more for his work.
But as this video shows, K. Eric Drexler is STILL ignored and his contributions forgotten by most people, smh :?(
10:25 - as a gearhead, when I hear oxygen is being added to ethanol, it makes my twitty tweeter a little extra
Joe, can you do a video on time zones? Specifically, when mankind realized that different locations had different local times, and what caused the creation of time zones?
Ralated Topic : The PROTEIN FOLDING problem. I would love to see a Joe Scott breakdown of this. Anyone else? I first heard of it in 2003 as a CS major in college and was fascinated back then, and it has had some recent break-throughs in recent years, I think.
I think "Baitwatch" is already taken.. Most people call it TikTok.
As a time traveller i can say that nanotechnology will be a weapon to surpass Metal Gear
I have been making nano metal powder for 25 years. so many awesome technologies have been developed
I love the little jokes and the skits you put in .
Clone skit was funny...
Isthmus...
Just makes me smile.
My ex partner made me homeless.
I had to live in my car for a year.
Obviously with no TV......my phone and TH-cam were my go to at night.
You kept me company and on many occasions the only time I had a smile on my face that night after having nothing to smile about all day.
thank you Joe.🙏🙏
When you have a smile on your face whilst learning something it makes it that much funner.
Don't change.
Keep doing what you're doing.

I like how much thought you put into fishy tv. It's often the little things that show true creativity.
And some of them is actually finfluencers.
You can find the universal paperclip machine online as a browser or mobile game. It's wicked fun, I recommend for any incremental game enthusiasts.
I'm really glad you're ahead of the game on this technology. Not sure about the feed tho.
Haven't seen anyone address to possibility of mutation in self-replicating nanotechnology.
I like the peiso electric wood, if you put a line of them on the pavement/sidewalk you could reduce the number of lampposts lining streets and roads
There's a novel by Michael Crichton called 'Prey' and it's literally about a 'gray goo' scenario where things get out of hand to say the least. Yeah, the concept is pretty scary because in my opinion, it's more plausible than AI turning against humanity. Or aliens invading. Just a machine doing its job.
Given this perspective on nanometer scale, let's think about the fact that the current generation of AMD's AM4 CPU architecture is built on a 7nm transistor platform. That means that each transistor is 1,000 smaller than the thickness of a red blood cell. And that's the generation that's on it's way out...🤯
I will watch the ad just for how smooth that transition was 😂👍
"Continuum " and "Travelers" had some cool nanotechnology
That was cool! Even though the floor idea is probably the lesser impactful one, I think it is very neat.
You had to have teratoma right when I was eating. I assumed I was ok to eat with this video. Thanks Joe.
What about String/M Theory? There was a "Golden Age" where Brian Greene and Michio Kaku were everywhere, popping out books & shows left, right, up, down, charmed, and strange and then somebody found the God Particle and then... Nothing. No progress since.
No Greene or Kaku anywhere for years now, at least from a content perspective (unless I missed something). Not even a sitcom starring Greene, Kaku, and Neil deGrasse Tyson as dysfunctional roomies.
.. with Sabine as the neighbour always borrowing sugar, PBS Matt as security. Nice idea, needs work :)
good question ... what does it weigh ... shrinking means same relative weight at scale ... so it will not collapse the ground .. the ground actually exerts no effort once you stop moving ... the speed will be 60km/h at scale .. so whatever a km/h is at the scale of the shrunken craft
‘paperclip’ was an apt metaphor to use.
Man, you're next level, and I also have the frustration when we have the technological capability but still, the tech is not in use.
Another prominent figure in nanotechnology is Eric Drexler. Marvin Minsky was his doctoral advisor back in the late '70's
I’m familiar with the concept of Nanotechnology. It was a child-like enemy then an ally in the 2003 Teenage Mutant Ninja Turtles, a health bar/healing system in the Ratchet and Clank video games, and of course, a fearsome weapon in the 007 James Bond movie No Time To Die.
Science and technology can be good, it can be bad, it ultimately depends on how we choose to use it.
