"Adding a handful of atoms" Damn that's a lot of atoms

Please avoid using AI or even search your answer in google/internet. Thankyou and Goodluck to your exam.

Kaway kaway sa mga nanonood dito dahil sa kinginang STS

That's the kind of title Ted talks should have.

For those who got to the end and had no inkling what he's actually doing: The challenge is very hard: You have a bunch of carbon nanotubes that you want to make into a computer circuit, you want to get them to sit down on a silicon wafer in a way that allows you to make billion-element circuits with switch sizes smaller than today's smallest transistors. How do you do this? The solution, in principle, is actually very simple. You suspend a bunch of individual carbon nanotubes in solution. Then you make very fine patterns of things that stick nanotubes and don't stick nanotubes down on your silicon wafer. Then you just wash the nanotubes over the silicon wafer until they stick in the right place. Well, in detail this is actually really really hard to achieve: First, you need a way of generating patterns that are denser than those achievable by modern lithography. People have come up with very clever ways of doing this. Two of the best ways are something called block-copolymer lithography and DNA nanotechnology. In either case what you are doing is making chemical polymers that self-assemble together to create very fine patterns. Second, you need a way of purifying semiconducting carbon nanotubes, cutting them to the exact right length for your circuits, then suspending them in solution. This is actually also no an easy problem, but people have come up with ways of making small polymers (eg, short strands of DNA) that bind onto carbon nanotubes, wrap around them, and suspend them in water. Third, you need to create just the right interaction between the patterns on the surface and nanotubes in suspension for them to land on the right spots and wiggle into place along the patterns you define. This is pretty hard. You need to engineer the right chemical handles onto both the surface and the polymers wrapping the nanotubes. You might have to have the surface help channel stuff into the right place with morphological features. Then you create just the right conditions so that nanotubes will align themselves onto surface patterns via many weak chemical interactions (if the interactions are too strong they can lay down in the wrong directions, make tangled messes, etc). This is pretty hard. People are still figuring this out. Lastly, you need to scale up all of these processes so that IBM or Intel can make perfect wafers with literally trillions of these devices. This is -really- hard because once you get down to nanoscales, thermodynamics fights against you every step of the way. You can make things easier by simplifying the requirements for assembly: eg instead of having nanotubes lay down on the surface to make circuits, just have them all forming parallel arrays pointing in one direction. Use lithography to define the other features that make up the circuit on top of them. Even so, it takes tons and tons of work. Finally, here's the one question that nobody has asked: Why carbon nanotubes? It turns out, it's not impossible for Intel or IBM to make transistors that are about as small as carbon nanotube transistors. The problem is that if the electricity flowing through the transistor is carried by silicon, there will be so much power dissipation that your CPU will literally melt itself before you can finish one game of Call of Duty. Semiconducting carbon nanotubes, are just about, the most power efficient semiconductors known. Graphene could be even better but it's actually not a semiconductor, so, no real good way to make it into a good transistor. So, carbon nanotubes are really, one of just a handful of materials that could possibly allow Moore's Law to continue down to transistors on the size of 10 nm wide or so, which is why IBM is still at it. (BTW, 10 nm transistor is not the same as a 10 nm node on the semiconductor roadmap. The 10 nm node actually has much bigger transistors). Anyways, I hope IBM succeeds. I'm rooting for them.

Nanomachines son!

"Elevator to space" The Sun: that's illegal

Good job TED.

Hello 1st yr BSBA students from SFC nga tan aw ani because os STS.

An great example of an excellent science communicator!

Always beautiful lessons in these videos, such knowledge and beautiful logic

tl;dr use chemistry to make carbon nanotubes assemble themselves to create a new generation of electronics, computers, clean tech etc

Can't wait to make space in my day for this video! Looks good already!

can't wait to see what comes of this. really cool

Wonderful talk! Love the 'we are the ones late to the party'...love it!

Thanks George!

Really bro? All that buildup just to tell us that we're missing "chemistry"? You're not even gonna elaborate on anything specific, like a new chemical process being developed or whatever?

Nandito ka rin ba para sa STS?😂

I remember nano-everything being on every single science mag cover 15 years ago.

This shows how brilliant nano technology really is thanks STS

This guy so reminds me of Jeff Goldblum. He got the looks, speech, body language and even the glasses down pat.

It's been a long time since I last watched something this good in this channel. Keep up like this!

Still damn waiting for a decent nano-coating I can have applied to my car (incl. windshield) so I never have to clean it again.

so good!

This is the key point: Everyday our tool gets sharper and gets more precise.

Marine biologist and great subject matter. Great science.

thank you sir

Awesome video.

So the first step I was thinking was...you need a model or set of parameters for the particles to follow. Let's dumb it down and say it's a flower vase. Simple shape to make in a 3D modeling program. Then what if we set each point as a place for the particles to go. That is all sound hypothetically...but then how do you get the particles to move there? And what kind of particles are these? Could we somehow involve magnets or magnet fields? Way above my pay grade, but if I had the money for it I would invest heavily into this tech. Seems world changing

ms tracey from bayside if ur reading this u are the best teacher ever . thanks for the fun in 6th class. ~Joshua

The creators of the simulation program we're involved in are great builders of images that are made from the processing of information. Man will never be able to build as well as they can.

Fascinating

Really intersting. I honestly can't wait to see these kind of things become reality.

STS be like. Watch the video on RU-vid entitled "The Next Step in Nanotechnology" by George Tule ski, Ted Talks.

Mabuhay ka STS!

Unsung heros of technology.

That dive bomb at the end tho lol

Wow, ideas actually worth sharing for a change! Stick with science, TED!

He just said something like 'water is wet". Ok. We got it. What's the news ?

I always liked Jeff Goldblum

When we learn to do this properly we can start creating open source computational hardware which can be expected to be safer than current hardware, because of possible manufacturer backdoors. Cheaper, smaller, faster, more power efficient and safer.

I have to wonder, Is this like the flying car, or the transistor? A hollow hope (like last time), or simply something that needs a second shot to completely revolutionize everything?

New proposals for renaming TED: VaS (Vague and Superficial) SoNR (Science, only not really) StS (Skimming the Surface) BatBS (Beating around the Bush, Scientifically) WLaS ( Waxing Lyrically about Science) This guy's motto: Rome wasn't built in a day, neither will I get to the point in one. TED's unnoficial mottos: - Speak in multitudes but say nothing - Science Lite

Where's the more in depth talk about the chemistry they are using?

All things he said sums up to chemistry on the nanoscale. But there should have been more information on progress made so far.

how about using A.I. based magnets which would put the statue together?

scary but awesome

I think his intention was to encourage or inspire new nanotechnology´s scientists.

As a sculptor, I gotta tell you you have to re-work your opening metaphore. "millions of tiny stone dust particles" can indeed be assembled, dude, its called clay, and you build it up by adding, building the form up in space, as opposed to the subtractive or carving method employed by a stone carver, removing dust.

We've been throwing the word "nanotechnology" around for decades yet, despite only our bests effort, we are only inching closer to that molecular-scale frontier when in fact we should be racing towards it. -Deus Ex Human Revolution

Great .that is i wait for a long time. Класс то что я долгое время ждал высказал до детали мои аплодисименты.Теперь надо всё воплотить в деле.

Would be cool to Flash Build.. Have a computer linked to an area. The area full of electric chips or whatever. Flash the blueprint on the computer to the chips, therefore electrifying a hologram of the blueprint. Pump the nanotubes in and they'd begin to form around the hologram. After some time, turn off the hologram for the nanotubes to cool and become solid. -THIS IS ALL IMAGINARY-

What if you had a 3D printer, with NanoTech Particle and you would upload a design and it would program these nano particles to build themselves into whatever you want...

These are not just words. He actually came with the prototype of the nanocomputer his team's been working on. It's just very hard to spot.

where can i find the scripts of this video I'm learning English so I would like to obtain it cause I will be very useful for me at the moment to compare my writing with the scripts.

The discovery of programmable matter, so it will assemble or construct anything will change everything.

If anyone would know, which engineering discipline could relate the most to the field of nanotechnology?

What about proteins that work like machines in nature. Could this be something that we could use to help with these issues? May seem ignorant to state but may be something in the thought.

Speach was nice but i can't comprehend what is nanomaterials exactly. I think he should do more in depth information but it was benefit for beginner like me

can't wait to get my nano construction kit and create the gray goo

Sand sculptures are statues made from millions of tiny particles... at least I would consider that a statue made from a pile of dust, hardly impossible.

Nano in our bodies now

For anyone disappointed in the science depth or lack thereof the Ted talk. It's because he was basically a sales man trying to get investors/donors or whatever scientists call their source of money

Louis CK gives the best description of a double edged sword.

Can nano particles be used for telecommunications and synthetic telepathy?

Over seven years ago, so how is that progress going?

Always 20 years away

my interest in nano technology is IMMORTALITY.

here's my uneducated idea. You could (maybe possibly) use sound waves to control large quantities of nanoparticles, but they'd still have to be malleable like the spooky dust from. (the day the earth stood still)

Y’know, I’m an aspiring engineer, and I love machining. I just watched an ad that basically just told me that engineering is gonna die. I know nobody cares, and in a about a few years somebody will randomly comment on this when it’s on their recommended, but that hit me in the feels y’know?

What are the possible innovation can nanotechnology can offer???

elevators to space aren't possible however spires to helipads to satellites are possible lol

Uuuuhhh ... sand castles building themselves? I hadn't realised that I shouldn't have been able to build them as a kid :)

Where are the nanobots? We have seen devices assemble themselves for various uses already. Why wasn't that referenced and expanded upon?

Hello again, sts!

So it's still nothing but a promise, not a single practical achievement is shown:(

How about using engineering games using knowledgeable nanotechnological constructs to build possible scenarios? What do you think?

wouldn't it make sense to create a dna molecule that provides the instruction to build the thing you want using raw materials that the manufacture feeds the product through cell division?

great video man

So we just have to wait until the exponential innovate hits nanotech and in since that moment in 4 months everybody will be riding transformers to work

is holographic nano printing possible for computer chips?

Kaway kaway mga ka buddy kung nanunuod neto..Hahaha

Nanites for space mining. it may be easier to assemble something from a bunch of nanites than trying to land a single shuttle on a asteroid.

Snake? Snake?! Snaaaaake!!

STS SUBJECT BROUGHT ME HEREE ! YEAH SAY HI IF WE'RE THE SAME LOL

So that´s why I need my pHD in nanotecnology...

Nano is a fair ideal. At least, kilo is the ideal that systems like our current should achieve at least.Ultimate sustainability is the key.

what is the chemistry? Form a bunch of C-C bonds to build a circuit? Seems simple enough.

i am thinking about immortality here , modifying ourself so much so that we can literally wander around in space , go through highest of temperature to lowest finding about the secrets about the universe . Spreading our consiousness to the the whole universe maybe multiverse . Able to turn ourselve into any smaller or bigger being . Then manipulating matter with our thoughts . actually making what we imagine . Maybe there is a being who has already done it . Maybe we are part of its thoughts . I can see so much possibility .Because of this. Thanks TED

& in time, the nanobots will hold TED talks on the next step in nano-nano technology.

forming a sculpture out of dust particles? you mean like clay? :)

Can these nanobots be programmed individually?

cool talk but he kinda stated the obvious :/ I'm currently in my 4th semester in engineering in nanotechnology and ever since 0 semester( trial run to see if you have what it takes) my professors have told us that the main way we are going to make any advances in the field is if we focus on chemistry, the best way to create and use nanoparticles is via chemical reactions

compel millions of particles to build a statue... => casting.

I'm here for STS. Lol

Sounds like he's saying nano builds on us. Morgellons

Or, you could put the dust in a mold and fill it with glue.

why is nanotechnology likened to creating a statue out of a pile of dust?? tho

IM here to answer the supplemental activity on GE7. LOL

Let me summarize this for you: "we still havent figure out how to create things at nano scale"
