R.I.P. George F. Smoot (1945-2025)
We will no doubt read many official obituaries in days to come, but all I can say is that he was a character, a very original thinker, a fine scientist, and a very nice man. Along with many others, I will miss him enormously.

This diagram is excellent and 100000% correct.
Possible causes of your problems. It’s a diagram that (sadly) still seems relevant in 2025, so reposting a year and a bit on.

i find this image so fascinating. it is both a literal example of authoritarianism but also a second-hand reproduction of the aesthetics of other authoritarian states. it's like a simulacra of authoritarianism whose purpose is to attempt to make the simulacra real.
This is a real photograph of Washington, DC this week, where the United States president has ordered military occupation in peacetime, and ordered the display of colossal portraits of himself.

New regulations are needed to protect #RadioAstronomy from satellite mega-constellations.
We deliberately build our telescopes in the outback to avoid radio frequency interference (e.g. from TVs, microwaves, phones) but now unintentional transmissions from satellites are affecting images.

We've known for a while that satellite mega-constellations like SpaceX's Starlink are a problem for optical astronomy. Now, a new survey shows they're also adversely affecting radio astronomy – including at wavelengths supposedly protected by international regs. 🔭⚛️🧪 physicsworld.com/a/starlink-s...

When I was little, the U.S. military came to our home at gunpoint and took me and my family away. We were imprisoned for years in barbed wire camps simply because we were Japanese American. I have spent my life telling that story, hoping it would never be repeated.
