I don’t think anyone is prepared for what they just did w/ ICE.
This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined.
It is setting up to make what’s happening now look like child’s play. And people are disappearing.

What is common knowledge in your field but shocks outsiders?
“4 phases of matter” is pretty bogus. Interesting materials have tons and tons of phase transitions, so the amount of “phases” a material can be in is a pretty murky idea.

“Falsifiability” does not demarcate science from non-science.

If you try to “warm up” a gravitationally bound system (of, e.g., stars or dark matter) by adding heat, you end up making it colder; if you take heat away, you make it warmer

The Minnesota shooter apparently used data broker websites to find the home addresses of the people he shot and murdered.
Congress has had years to do something about data brokers and they've sided with the tech lobby over and over again.
Their inaction is deadly.

They don’t believe in any gods and can’t read the Bible. How can they possibly do the morally correct thing?

I just rattled a few TB facts off to my medical provider as I was getting TB tested for school and she responded “have you read everything is tuberculosis?”. Unreal moment @johngreensbluesky.bsky.social

No money was actually saved, but at the same time we had truly devastating cuts to scientific research, medicine, and foreign aid. Just reinforces what a tiny fraction of spending those areas always were, with an outsized positive impact.
Of course it was.
DOGE fired a bunch of people while managing to save almost no money at all because Musk et al were primarily interested in performative cuts to fight the culture war. So taxpayers got a less efficient govt for the same price. But at least the libs were owned.

Every businessy guy I have ever met who finds out about Crash Course tells me that we're not just decreasing our revenue by not building a paywalled business, we're also decreasing our impact. This is wrong...and this video shows why.

The National Science Foundation (NSF) is terminating a bunch of research funding. Much of this is in line with the goal of making sure nothing gets in the way of systemic racism and sexism, but they also explicitly target research on "misinformation/disinformation."

Last week I encountered someone who graduated from a public high school and now attended a public university advocating for the eradication of the department of education. How does that make sense at all???

“But with love comes loss, son. It's part of the deal. Sometimes it hurts, but in the end, it's all worth it.”- one of the most beautiful, and to me deeply true quotes I’ve encountered in fiction. Source? Some kids movie…

Just finished #everythingisTB by @johngreensbluesky.bsky.social and, wow. Never have I been more invigorated to act as well as deeply frustrated with systems of injustice that cause TB today. If I were to compile every quotable sentence from the book, I’d have an exact copy.

I know the Signal group chat story is beyond funny and please keep posting all your memes about it, but this concern for Saudi oil and not for, say, Yemeni children is something worth noting I guess.
