Quasicrystals
- priansh 7y agoCan 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!!!)
- Randor 7y agoA 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.

- wwarner 7y agoPenrose 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 https://www.gregegan.net/APPLETS/12/12.html

- TheAuditor 7y agoInterest in quasi crystals, crystallography and quantum emergence seem to be on the rise.
- core-questions 7y agoWell that was a rabbit hole to fall into. The emergence stuff reads like pseudoscience to me, though.
- cozzyd 7y agoThe 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.
- notfashion 7y agoHe 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?
