Room Temperature Superconductors

I missed this. Someone says they made a room temp. SC and published it in Nature. The first link is a lot more readable, and the doing of the thing is more chemistry than EE.

A SC is something that conducts without resistance, but that causes a host of other issues. This one doesn’t look usable in and of itself, yet, as it’s super tiny under about two million times normal air pressure. But it worked at around 58.F, which is amazing. What’s important is that the pressure and size may merely be engineering problems, and where there’s a lot of dollars, there’s a way.

Maybe not. There could be some other limits involved. But it’s still pretty interesting.

Edit: I left unsaid, but perhaps should have said, I haven’t seen anyone duplicate this work yet. Repeatability is the trick. So caveats and ifs and conditionals, oh my. I’m still pretty excited.

Mara’s back.

This weekend? Please, powers that be, let me get it done this weekend.

Mara and the Trolls in paperback coming soon.

Meal Plan

I was in the cafeteria getting a plate. There’s a glass wall between me and the food, and the cook has to serve everything. I point at some yellow stuff and ask for squash.

The cook looks at me oddly and says that’s collared greens.

I ask, “The yellow stuff?” It’s obviously squash.

The guy winced. A moment later he said, “Yes, that’s squash. Sorry. I thought you were pointing at something else.” He looked very embarassed.

I felt sorry for the guy because I’ve done that a million times. It’s probably the cook-version of saying ‘you too’ after someone tells you to enjoy your meal. It’s a little weird to think about the other perspective.

The squash was good.

Ant Financial

There’s this thing caled ‘regulatory risk.’ Ant Financial just found it.

I’m very curious how deeply exposed some American financial institutions were to Ant. WSJ mentioned Blackrock and Fidelity, but were they dropping 0.1% on a flyer or 10% on a core position?

U of D

The walking paths around the grounds at DU aren’t straight. They don’t follow the shortest path. They’re all artsy. If you want to get somewhere, often you have to go around weird little curves.

It’s kinda annoying but kinda cool because it’s weird, artsy, and useless. They make me think of Amber.
