The smelling or "sensing" when something needs maintenance reminds me of my college professor who "listened" to concrete structures. Small microphones can detect microcracking in concrete structures and can improve the lifecycle of such structural systems as we hear more cracking during the load cycles. If we hear lots of cracks the system may need more maintenance to remain in service.

[@Dogtroll]

You know what would be an interesting topic, what about recyclable advanced materials? I mean think about it if you plan a mission to another star system that's going to take possibly thousands of years to complete recycling is going to be really important possibly more important than the unique properties these advanced materials can offer. If you put thousands of people into a giant tin can and send them sailing off on a mission that's going to take thousands of years then it's really important to take into account the fact that if they can't reuse these materials they may wind up functionaly running out of resources.

[@boobah5643]

Recycling tends to be an industrial process, and that means space, energy, and all that jazz. You build for endurance over performance, you build modular, you build redundant, and you build hot-swappable. You bring the spares you can, and you build so that failure isn't catastrophic so that when something _does_ go wrong (and it will) Earth can figure out how to keep the next ship from failing in the same way.

[@jasonisbored6679]

@Boo Bah Current US and most navy’s ships have industrial facilities on them - provided you don’t keep poking holes in them, and they have access to those facilities, they can rebuild anything except for the super highly technical bits like computers or radar or whatnot. Including this on spaceships manufactured in space (where a little bit more mass added isn’t so cost prohibitive as on earth) and it’s perfectly reasonable to expect it of slower colonial or seed ships.

Most of these are ecological hazards, funny enough. Many existing materials, say carbon nanotubes, won't break down and will cause various environmental issues. At least for plastics we know that near-term bacteria can chow down on it for net energy gain. Diamond-strength stuff not so much. At least outdoors this means we have teflon in our water, and might get lots of nanotubes in our lungs. Before we go city-scale industry with a new material, at least for exteriors, it should become standard to tune our purification and environmental cleanup systems. The way new materials will be cleaned up, at least in areas near explosions and warzones, is akin to clearing depleted uranium. Or normal uranium with future mining tech.

[@brookefoxie9610]

Of course, let's not forget that plastic was inedible and wouldnt break down either. There would inevitably be something in nature that chows down on this new food, but yea pollution is still a serious issue especially as it would just be an extra pollutant in addition to plastic.

[@Curry-tan-]

@Robert Reynolds As usual that runs into Tragedy of The Commons until problems are profitable to deal with, which also disincentivizes cleaning up unprofitable areas. 2kg of depleted uranium spread across 1/2 km^2 of a town isn't in itself very lucrative even before terrain is considered. The margins also award scale which is anti-competitive, similar to the endgame trajectory of CO2-extraction farms. So maybe you're right under some contexts but in general I disagree. Well the overall mover on these incentives is the large-scale economic power-balance so who knows.

[@ST-ly8uf]

The key is to think long term and the key to that is to educate women in the "third world." If we can reduce the fertility rate in places like Africa to 2.0 or lower, the continent will see rapid gains in efficiency and GDP per person - that and fixing the damage already done in the oceans will go a long way to fixing our problems. I can also see the potential of new jobs opening up in the disposal of these materials.

[@ST-ly8uf]

@Robert Reynolds Why would you not want the fertility rate of badly impoverished nations to drop closer to the level of Europe? Especially since, doing so is achieved by educating women and providing contraceptives? What is the issue? Educating girls? Providing cheap and effective contraception? Why should Africa not embrace a lower fertility rate that will allow her to invest more in each individual and rapidly raise her living standards?

[@ST-ly8uf]

@Robert Reynolds The solution to that would be to have the developed countries - the already developed countries of Europe and Northeast Asia - have more children while Africa cools down. Besides, at 2.1 children, Africa would not need immigrants since her fertility rate would be replacement level.

With regards to making materials with lasers, I've long considered the possibility of using holograms to bulk-pattern materials. Imagine something looking not all that different from your typical "holographic" foil sticker used to produce the laser peaks and troughs on a substrate, every tenth micron or so, to encourage a chemical vapor to settle in just those spots, being ejected from other spots, and bind with the substrate and other materials already present. Swap the hologram for another hologram, and introduce the next gas to bind every tenth micron or so. Basically, using holograms as a sort of stencil for laying down materials, quickly, but with nano-tech precision. Of course, to achieve this, you probably need holograms that involve EM down in the longer wavelength X-Ray range.

One of the many nice applications for high temperature superconductors is low loss transmission of work. So for example in a conventional bike you pedal and the motion is transmitted to the wheel by a chain and sprocket. With a high temperature superconductors you can make very small ultrahigh efficiency motors, since you can make much stronger and more compact magnetic fields. So in the case of a bike you'd have two superconducting motors linked with a superconducting wire and the work input into one would instantaneously be transferred to the other. Kind of silly to use such sophistication on a bike, but the point is that you can suddenly substitute any mechanical transmission with superconducting wires, over any length. To humans from the future mechanical transmissions will seem like the silliest thing ever.

Also, since it comes and goes i have a pretty good comparator for flavor and I can safely say that while scent is certainly a part of flavor, the usual listed number of 70% or so is wildly high. I'd personally put it at around 35%, a significant fraction, but not a majority.

Great episode. I like the thought of 'shielding' gravity rather than actual "anti-grav."

Notably, how something like that would might work for building a skyscraper, hauling freight, and such; i.e. a low-quality apartment giving residents vertigo when they walk past certain spots, or 'center of gravity'-related accidents when unloading a low-grav lined truck. Or partially replacing elevators with Metroid-style vertical low-grav corridors (i.e. jumping from floor to floor), all manor of flying drones, a massive ship or island that experiences lunar gravity greater than (or similar to) earth gravity, so on.

When his friend asks the machine to make Nitrogen the machine said it can't. I just can't put my finger on why this image reminds me of that tale.

So, not only would metallic hydrogen be a great fuel, it should make a great radiation shield as well?

[@Nethan2000]

Sure, except it might also have a problematic property of exploding very easily due to quantum tunneling into regular hydrogen and releasing all the energy that's inside it.

[@bobthebomb1596]

@@Nethan2000 Wouldn't that also apply to its use as a fuel in that case? I don't know, I'm not a physicist. I was hoping for replies from people who are and have more knowledge than me.

I just learned that only elements with even numbers of elektrons can be semiconductors in a lecture. Thus sadly the answer to „How can you make a semiconductor out of hydrogen?“ would be „Sorry, you can’t.“ Maybe Helium thought?

Material that can cut space or even send it as a beam. I would love to live in that future. I believe that would be the last big scientific breakthrough.

So minor thing. Moore's law is about the density of transistors not the speed of processing. We're still on the Moore's law train last I looked. However the power dissipated by a CMOS chip is proportional to the clock speed. So we had to stop increasing the speed so the silicon wouldn't vaporize....

[@davemarx7856]

We really have to break out into space first. Alot of materials out there to work with.

[@kdegraa]

Actually it’s mostly empty with long distances between anything much.

[@davemarx7856]

@@kdegraa still more raw materials out there than there are on this solitary planet.

Can they make a Reece's cup that wont stick to the paper?

I think materials science is going to relate to so many topics covered here. I was thinking about consciousness - if it comes is found to come in the form of light - then we can make synthetic brains easily! I want materials science to be the next renaissance in science!

What does it say about me that I enjoyed this the most of all the hundreds of SFIA vids I've seen. The only one I've watched three times.

[@SkipAd_Vegas]

great video..TY ...also, old-school comic geek factoid: The X-Men's character Colossus is osmium steel.

[@Phantom-kz9bv]

Not making this up. Because of this video I’m seriously considering going into material science as a major. Thank you for this amazing video

[@cluckeryduckery261]

Been a while since i caught one right at upload, lol

[@Dina_tankar_mina_ord]

I really enjoy your deep dive in these topics.

[@extropiantranshuman]

this video's above my head. I need to expand my brain before I proceed any further just to understand it

[@RandomYT05_01]

I am going to point out that with the detection of the first warp bubble, Warp drive is now a near to mid future technology that seems to be moving out of Sci-fi into Sci-fact. I'm betting between 2050 and 2100. Isaac, please do a video addressing what we could do with such technology.

This is the most interesting video you have done so far . I like deep dive and it broad application at the same time.

I really would like to know how the world looks like in 10.000 years...

[@Namkify]

look at Mars or Venus

I think developments in photonic circuitry is worth looking into, with it being a potential low energy low temperature high speed electronic alternative which theoretical has the potential for near to higher then room temperature quantum computation.

Magmatter, or more commonly, Xeelee Construction Material (guess you could call it Mythril, too)

[@TheMidnightMinute]

It's highly probable that the rate of material science advances will increase exponentially over the next few decades as AIs make predictive models of chemistry and physics and begin proposing scientific experiments to test them.

[@AEONIC_MUSIC]

This is one of the reasons I'm getting into ai now

[@cmdrcrimbo]

Quasicrystals and their predicted uses would be a fascinating topic for a video on its own. Total invisibility is just the tip of the iceberg. (edit) Transparent aluminum is not the only metallic glass that can be made.

I think of the Greek letter "Mu" as an *M* with that drip...

Episode of the year hands down 👐 bravo Isaac

[@MG-te9ub]

strength and toughness are almost opposite characteristics in metallurgy. strength is the ability to resist deformation, toughness is the ability to absorb energy without cracking. Last I knew copper is the toughest metal
