- Comment on These gender reveals are getting rather ridiculous.. 4 weeks ago:
Oh cool! I hadn’t considered that. The crystallin and vitreous humor in the eye do indeed have a refractive index similar to water, so Cherenkov radiation happens at less than 1 MeV IIRC, so it comes down to how much light would actually be produced in such a small volume. It does seem perfectly feasible!
- Comment on These gender reveals are getting rather ridiculous.. 4 weeks ago:
Somebody please correct me if I’m wrong, but I believe due to the very low refractive index of about 1.0003, particles need tremendous energy to produce Cherenkov radiation in atmosphere. So the demon core flashes (while perhaps some small part Cherenkov) were probably mostly just from the ionization of the air, and subsequent recombination.
If my awful phone math is right, you’d need about 21 MeV of energy for an electron to produce Cherenkov radiation. I think the processes producing energetic electrons here (Compton scattering, some pair production, photoelectric effect, internal conversion, delta rays, and Bremsstrahlung cascade I believe) should regularly produce energies around 10 MeV at most from Compton.

The entire series is incredible, if you have the time. It really left an impression on me.

electroweak unification
Oh, that’s easy! Just take your understanding of how spontaneous symmetry breaking works in QCD, apply it to the Higgs field instead, toss in the Higgs mechanism, and suddenly SU(2) × U(1) becomes electromagnetism plus weak force!

- Comment on Texas Needs Equivalent of 30 Reactors to Meet Data Center Power Demand 6 months ago:
Texan here. I don’t have a generator. Blackouts basically haven’t been a thing in my area since like 15 years ago, so it really depends on location. Also my electric bill works the same way as it would in any other state; the problem is when people buy electricity at what you might call “market price”; most of the time it’s cheaper, but you get fucked over sooner or later. It’s kind of like that story about people’s AC being controlled by the power company. They signed up for a program that explicitly set your AC higher during high-demand periods and then surprise Pikachu faced when the company did what they said they would do.
That said, our grid is still definitely trash (as are many other things here) and I’m desperately trying to move. Basically the only thing we’ve got going for us is the food is amazing.

- Comment on Ukraine isn’t invited to its own peace talks. History is full of such examples – and the results are devastating 6 months ago:
The alternative is making Russia getting/keeping the territory a worse option than leaving Ukraine the hell alone. I agree that the unfortunate reality is that Putin will never - can never - give up the war willingly without concessions, but the flip side to that is they’ll be back for more sooner or later. We have to make the war such a bad option for Russia that Putin is deposed, whether by his oligarchs or by the Russian people. It’s a difficult fight, but it’s one we’ve fought before on 3 fronts in WWII. The difference, this time, being nukes exist and that understandably makes a lot of people nervous - but again, expansionists never stop. The confrontation has to come at some point unless we want all-out war in Europe.
I’m far removed from the situation, so my opinion isn’t worth much on this part, but I think realistically maybe there could be some concessions around Crimea for a peace deal - sort of a status quo ante or similar - but Russia would have to make some concessions in turn for Ukraine to agree (NATO peacekeeping forces in Ukraine? Still a no-go for Putin though…). Ceding Ukranian territorial losses from the current war, though, will only put off the eventual confrontation, and hurt the West in the meantime.

Giving away conquered territory in hopes of peace is called appeasement. Historically, it doesn’t go well.
