It turns out it’s surprisingly difficult to take a selfie in a welding helmet,
as its safety shutter is triggered by the phone screen’s brightness. Squinting
at a steep angle seems to do the trick.
It turns out sapphire is a very useful high-tech material, due to its hardness,
insulating properties, optical transparency, and thermal conductivity. By
starting with a tiny seed crystal, a huge column of highly pure crystal can be
slowly drawn out of a molten vat, producing big honking specimens like

This is the nanolaser equivalent of being smacked in the face with a slab of
corrugated roofing during a tornado. There’s one step in making microscopic
lasers where you have to peel away metal from much of the substrate, leaving
behind pillar-shaped lasers surrounded by small metallic patches.

I finished my PhD! (!!!) Thanks so much to all of you for following so far, and
giving me a use for the interesting images that wouldn’t necessarily make it to
publication. I’m glad I’m not the only one amused by strange-looking dust
