As an American who has been in this specific competition for my entire life, the main result has been that my work is better precisely because I had to compete against the rest of the world for my jobs
Artificially restricting open competition is un-American to the core
"Why doesn't a charge sitting still on the surface of Earth radiate" has many good answers but this paper is my new favorite.
If the earth was big enough that the radiation zone of the charge was within the "approximately flat" local region, the earth would be a black hole 😎
@martinmbauer All true, but many of those effects can also be explained by classical or semiclassical radiation. To really nail it down, add sub-Poisson photocounting, Bell violations with light, entanglement in light-matter experiments…
Here is a thought experiment on the "physics is broken/dead/stuck" discourse that keeps showing up. Suppose Steve Weinberg was born in ~2006. Would he go into physics today? If so, what field?
@eviciium Totally reasonable question! Some answers:
1. Flex
2. It's a way to measure gas pressures at levels that are currently so low that existing sensors just measure 0 (https://t.co/3j5y2Yco27)
3. Characterizing backgrounds for fundamental physics measurements we want to do
2024: proposal to make a gas pressure measurement by literally counting every collision with a sensor
2026: measurement.
Could not be happier to see this work exactly like we drew it up

@Jess_Riedel Yeah, I think that's right. Cooling these spheres to the ground state (or even putting them in squeezed vacuum states) is possible, but it's not needed for these impulse measurements, fortunately... https://t.co/PCWlycNoGv
We invite applications for Research Fellow positions as part of a new initiative to be launched in late 2026 at the interface of quantum information theory and gravity! Please RT and let potentially interested researchers know. 1/
Dude, are there non-trivial non-pathological Lorentz-covariant Lindbladians in QFT or not? Are the current no-go arguments like Myrvold [1709.03219] as strong as we can hope for? Is the situation better understood in classical field theory?
this morning i have received emails about:
-nuclear winter
-claude can hack anything
-fluffy animals wearing berkeley physics shirts
this era is so fucking weird
@Muppetsexual@avfeyn137@jonathon_gault Sound in solids can be quantized into phonons. Sound in dilute gases cannot. It depends on the condensed state you are expanding around
Gravity is probably quantized into gravitons.
If not, however, there are experimental consequences. In particular, some level of irreversibility/noise. We finally classified ~all such models and calculated the noise.
