Unconstitutionally taking money that the law says must be spent on one purpose & using it for something else—when it's to establish personalist control over the FUCKING MILITARY—is about as dangerous a constitutional crisis/failure as you can imagine

Via: www.nbcnews.com/politics/tru...
The Office of Management and Budget sent a notification to Congress about their intent to use research and development funds to pay members of the military, two sources with direct knowledge tell NBC News.

A spokesperson for the OMB confirmed to NBC News that it plans to use the research and development funds and that there are two years' worth of funds available within the Department of Defense.

Russ Vought wasn't lying when he said he wanted to inflict "trauma" on our public servants.

This is what he is doing...with RFK Jr.'s permission at HHS. Last night, they destroyed our nation's ability to track and report emerging diseases/potential pandemics, among other things.

This cannot stand.

"Generations of Chinese women have been rendered voiceless by the patriarchy. Their stories refuse soft burials."
So honored to have a review essay out in Banned Books Week @chinabooksreview.com on two of Fang Fang's most acclaimed novels, Soft Burial & The Running Flame, tr. @bairuiwen.bsky.social:

This is quite literally, anti-science.

It is what happens when ideologues fit the data to the narrative and not the other way around. With these leaders in charge, HHS will generate junk discoveries, junk findings, and ultimately, junk cures.

Americans must turn elsewhere for guidance.

Recently learned that if you are an AFT member—as, for example, members of the UC Faculty Association are, if we opt in to AAUP membership—you’re eligible for $6/mo professional legal insurance. Useful if, say, you’re in a dispute with your employer. www.aft.org/sites/defaul...

Documenting what has been lost... and what still could be found with a renewed commitment to science in America.

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

Ohio State astronomy is still waiting to see what happens with the federal funding landscape before deciding whether to proceed. With programs that are still TBD, I recommend waiting right now because *application fees do not get refunded if they decide to cancel after you have already paid*!!

So far the astronomy PhD programs that have cancelled admissions are Washington, Michigan State, and Case Western.

There's also Kanopy and Hoopla! Libraries rule!

You know what's a great, free way to watch movies and listen to audiobooks in our declining empire? Your local public library (if still open)! I quit Audible when I quit Amazon, and I listen to more books now, through Libby, than I did before. Libraries have DVDs, too! Maybe even DVD players!

From a 2019 interview with Kitagawa -- "it was common sense that organic materials could not make a stable porous structure. People thought we were doing “useless” research because they did not realize the potential of the seemingly trivial space inside the pores." pubs.acs.org/doi/10.1021/...

Today's reading begins with Lise Meitner, who co-discovered nuclear fission (she wrote the paper!) and was in general an INCREDIBLE trailblazing scientist.

Except, as a Jew, she had to flee Nazi Germany to Sweden and lost her professorship in Berlin. The men she worked with got the prize instead 🧪🔭

Thank you for being so kind. You always are, and we value that.

Kvetch: Why does Bluesky give me no science (it did not even bring up last night's Nobel Prize in Medicine?). The Twitter, before turning into a cesspool, did that.

Michael Peskin might have been in the audience. Maybe. He got it. I never wrote it down, so curls still remain a problem set.

I promised to do it without a single formula. Might have been a lecture on Green's theorem for flux. I explained the birdtracks technology, and the rest of the lecture was only birdtracks, no letters. It was beautiful. Kiddies might be still digesting it.

The longer version goes like this:

In Spring 1985 I was a visiting professor in Cornell physics department. One time my friend Mitchell Feigenbaum asked me to teach his insanely popular graduate (no Jackson) E&M course that filled one of the large lecture halls. It was formula after formula.

Well, that has to do with my prejudices: 3d is just a special case, and I would never call 3-index Levi-Civita a "curl". But indeed, it's a homework - if you write it up, I'll add it to birdtrakcs.eu .
