Transparent Aluminium
(theconstructor.org)
Hello computer!?
You have to use the mouse.
How quaint!
*Picks up mouse and says:
'ok computer'
Then types over 100 WPM when he's likely never touched a keyboard ever.
That part always bugged me being a computer guy that actually uses a keyboard.

Not now, Madeline!
I noticed you're still working with polymers.
We’re gonna get transparent metal before the easy parts like to stop killing each other. Roll on Star Trek
TBF in the Star Trek universe they also do get transparent aluminum earlier than stopping the wars.
According to Star Trek lore, WW3 will begin in 3 years, and last for 27 years.
Buckle up.
Can we not? Please?
Don't worry! WW3 will be preceeded by the Bell Riots, a collection of revolts by people treated inhumanely and stuck in slums. It will be a fun little distraction before the fireworks. It's even got it's own count down now!
I want science fiction to remain fiction.
Edit: Aside from the cool stuff, that's fine, I'll have some of that.

You misunderstand, we're in the mirror universe.

Misleading name, on the same level as calling water "non-explosive hydrogen". That said the material looks promising, as a glass replacement for some applications (the text mentions a few of them, like armoured windows).
(It is not a metal; it's a ceramic, mostly oxygen with bits and bobs of aluminium and nitrogen. Interesting nonetheless, even if I'm picking on the name.)
Can I make a whale tank out of it?
Yeah your mom really needs a bath.

3 times as tough as steel and they're making bulletproof glass out of it...
There's a low budget pc game about colonizing Mars and this was one of the things in the tech tree
Crazy to see it as a real thing now.
Like OG aluminum, this is going to be crazy expensive at first, but in a century it'll likely be cheap and we'll see it replacing glass in the most mundane uses.
We'll see it replace phone screens pretty quickly tho. A few mm's of this and we'll have legitimately unbreakable screens, and even if a scratch happens, you should be able to just buff it out. They're probably wrap entire phones it honestly. One solid piece that makes repair impossible on your own.
Might be hard to assemble the functional part of a phone inside of a crystal, and you can't bake the whole thing because silicon isn't surviving 2000oC for 2 days.
Yeah, but it was a lot harder to make regular aluminum back in the day as well.
Increasing ductility isn't impossible, but it probably is unlikely in this case.
But two halves that get glued/sealed together permanently would be possible.

The obtained material, which is molded and opaque, is heated to 2000 C and kept at this temperature for two days
Fuck that's a long time and a high temp
Transparent aluminum is so weird, a piece of it was once passed around our office. It felt heavier and colder than I expected, which I guess is probably because it's much denser than most types of glass (I think it's only comparable to optical glass so it would be close to holding a high quality glass lens) and it looks like the thermal conductivity is way higher.

I had no idea this actually existed! Cool!
Here’s a more novice-friendly link: https://hackaday.com/2018/04/03/whats-the-deal-with-transparent-aluminum/
Thanks for that. Really cool stuff.
"Aluminum oxynitride ceramics have been around since the 1980s, so it’s not new stuff by any means."
Says it costs 5X the price of standard bulletproof glass, but that it's far stronger, and IR-transparent. Cool material.
Star trek comes to life, yet again.
This one goes the other way. It was first patented in the 80s before the movie came out. It just wasn't a big thing yet. I assume it's had improved properties since then, but the process already existed.
Unfortunately this is a time travel paradox. It wouldn't have even been patented if the crew hadn't gone back in time and needed it to transport a whale back to the future. I fully support the claim that Star Trek did it first in the future.

This seems cool.
Also upvoted for the correct spelling of Aluminium
The original discoverer of the element spelled it "aluminum". The British publisher that published his work changed the spelling. The rest of the world got the right version of the man's work. The Brits are wrong.

Scotty would be proud.
Would that make it a type of sapphire?
Types of corundum maybe but I think that’s a stretch. Sapphire is (usually) blue Al2O3. Ruby is red Al2O3. Transparent aluminum is Al2O27N5.
Watch faces are often colorless sapphire; I think industrially produced.
Any corundum without trace elements is colorless. Corundum with trace chemical impurities makes the gems we know. Chromium gives the red to rubies, sapphire has iron and titanium, you can get other colors using vanadium or different ratios. Gems are neat.

Aluminum oxynitride is transparent aluminum, but alpha aluminum oxide, which is also transparent, is called Corundum, Ruby, or Sapphire. That name is dumb.

How much would a transparent aluminum butt plug cost and would it be safe to use?
