In her #NWAV53 plenary, King discusses an example of a juror being dismissed from the pool due to forestressing in the word police (so PO-lice), because the prosecutor claimed that the pronunciation showed animus towards law enforcement. And this is exactly why I study prosody!

Valuable info about the Physics Nobel Prize today from Prof. Joseph Barranco at SFSU on Martinis and Devoret being a grad student and postdoc in Clarke's lab at UC Berkeley & Clark and Devoret being immigrants. "California *public* education made this happen. Immigration made this happen." ⚛️

@alliegoertz.bsky.social Matt Groening gave you a quick mention on today's WTF interview about how you were his first podcast even though he'd promised Maron. But, your interview was better

The gap between teacher pay and other college graduates’ pay is the highest it’s been in over four decades.
Is there a “teacher shortage,” or a shortage of jobs that treat educators with the pay, dignity, and support they deserve?

A key difference here is that while either can be incorrect, the structure of Wikipedia *creates context* and the structure of LLMs *destroys context*
Wikipedia has linked sources and an edit history showing where information came from and who added it when
An LLM just generates text

Some of the anti-AI stuff feels a bit like when people would say "don't use Wikipedia as a source." It's just like anything else, a piece of information that you weigh against multiple sources and your own understanding of its likely failure modes

@rhettallain.bsky.social Hi, Rhett! Do you (or the physics community) have a standard example of what 1 Newton feels like? Like Wikipedia has that the force of gravity on an apple is about 2N, but that's still not too intuitive to me. So maybe how hard you'd have to push something common?

To really make money on the stock market you don't actually want it to just go up. You want 2 things:
1. Volatility (goes up and down a lot)
2. Predictability
Then, if you have the TIME and MONEY you can ride those waves to fortune. That's why he's doing it. #RichGetRicher
