Re: Quasicrystals
#2Can we view Quasicrystals as relatively "low cost" or "more efficient" than steel?
The wiki mentions: "The Nobel citation said that quasicrystals, while brittle, could reinforce steel "like armor"
I'm seeing a lot of potential here for building more stable, unbreakable structures here for much cheaper.
(Also, Gundams becoming much more viable!!!)

A few months ago I spent some time looking for the Al-Cu-Fe-Cr quasicrystal frying pan. I couldn't find it so I don't think it's being sold anymore. I read somewhere that the material was reacting with acidic foods and removing the coating.

#4Penrose tilings have been shown to be 2 dimensional projections of simple lattice structures in 4 or more dimensions. Which is awesome. Here is a java applet that will draw as many as you'd like. https://www.gregegan.net/APPLETS/12/12.html
Re: Quasicrystals
#5Interest in quasi crystals, crystallography and quantum emergence seem to be on the rise.

#6The story of the expedition in the Russian Far East to find the natural quasicrystals is very interesting. I was fortunate enough to see Steinhardt detail it at a colloquium at MIT 5 years ago. Unfortunately I can't find a video of him giving the talk anywhere although I imagine most of the story must be written down in some article.

He wrote a book, published in 2018: "The Second Kind of Impossible: The Extraordinary Quest for a New Form of Matter".
But maybe this video is similar in content to the talk you saw?

Well that was a rabbit hole to fall into. The emergence stuff reads like pseudoscience to me, though.
