Postdoc at UC Berkeley and LBNL working on @simonsobservatory.org . I might work on the Cosmic Microwave Background, but my puns are never reheated.
The Department of Energy is tasked with a "Manhattan project-like" effort on AI and quantum computing. The Manhattan Project consumed about 1% of US GDP from 1942 to 1945. By that metric the new investment should be about $300B a year.

In 2024, the US government spent $3B on AI research. 🧪

I guess we should all apologize to Graham Plattner then (no).
Exclusive: The U.S. Coast Guard will no longer classify the swastika, nooses and the Confederate flag as hate symbols.

The military service drafted a new policy that classifies them as “potentially divisive.”

"As leaders, we lost our mission a bit about what higher education was about" says person charging students $70000 a year to get an education at a school with only a handful of PhD programs.
No, we didn't "lose our mission" & we didn't focus too much on identity diversity at the expense of viewpoint diversity, & no one knows the right amount of that (bsky.app/profile/mcop...) & no amount of granting the premises warrants the lawless authoritarian assault on American universities.

I would like to thank MNRAS, @theguardian.com and the authors in Korea for creating and spreading this dishonest dogshit so fast it made it to the audience questions of an outreach event I was at tonight. Top science communication by all involved.
"The paper is likely to be greeted with heavy scepticism, but with the influential DESI consortium independently reaching a similar conclusion earlier this year, a fierce debate is opening up in cosmology over the nature of dark energy and the probable fate of the universe."

The hardest part of teaching science these days is you get to tell young people about all the cool shit we could be exploring, but in the back of your mind you know we're not going to because the next experiment would cost $100M and we need to spend $50B to build a plagiarism machine to do scams.

René Girard was a mistake.
It needs to be emphasized that this paragraph is about Robert F. Kennedy Jr.

When there is a leak on a spaceship, Roscosmos gets to blame sabotage, CNSA space debris, and NASA Boeing.

Also the quotes and replies seem to indicate not many people understood the chronology from the whole article.

Why can we make raw milk cheese in France with short maturing without poisoning ourselves with E. coli and salmonella en masse but the Americans are unwilling to do so? Is it just a different appetite for risk and cheese?

A reminder that "Alien observations" is an anagram of "Avi Loeb's insane rot"
Avi Loeb's calculations about 3I/ATLAS are 100% wrong because he has never understood that dust in the tail(s) responds to solar radiation pressure. Solar wind shapes the ion tail. But the radiation pressure is about 1000 times larger than the solar wind ram pressure, for particles that feel it.

Apropos of nothing in particular, two cosmology questions for my followers:
- in the first figure, are the black or blue contours in better agreement with the pink ones?
- in the second figure, are the black or blue contours in better agreement with (w0,wa)=(-1,0)?

I have a feeling we can wait a long time for reactions from any of the 39 idiots who co-authored a book with Krauss last year about how science was under attack www.simonandschuster.com/books/The-Wa...

Today’s forecast: clouds
Tonight’s forecast: rain
Aaaaargh
We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.

Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

I talk about The Random Universe (the book, and the Universe itself) on [Sean Carroll's Mindscape. We cover epistemology, probability, quantum mechanics, cosmology and more. Sean and I were cosmology grad students at the same time, and it was a pleasure and an honour to spend time with him online.
