The first official quasi-crystal

 

Interesting paper;  turns out that when the first A-bomb was tested (i.e., blown up) in the New Mexico desert near Los Alamos, in addition to making crystals of the fused sand mineral trinitite, the explosion also created a quasi-crystal.  This occasion marks the first time a quasi-crystal was synthesized.  Of course, they weren't really trying to make one, but they did.

Here's a newsier treatment of the story:

A newfound quasicrystal formed in the first atomic bomb test

And this article actually has a picture of the quasi-crystal speck.

The red trinitite piece in which the quasicrystal was found wasn't real big, either.
