I am always confused about transposing instruments. Google AI results are not helping.

Working my way through the Feynman Lectures, vol 1, and suddenly several chapters on the physiology of the eye and color vision reminds me of Les Miserables, where you suddenly get 100 pages on the minutiae of the nuns of Petit-Picpus, or the history of the Paris sewers.

Trying a more plant-based diet, so it felt like I was making some kind of witches brew tonight. Had to sub fermented beans for the eye of newt. (Soup came out incredible, btw)

Another eland today, along with a personal best Saturday time. Not sure if I’ve ever actually seen “oribi” with its less common vowels.

10 min after handing out the first in-class exam in my quantum mechanics course, a young lady I don’t recognize comes in and sits down.
Sometimes students skip the lectures and only show up for exams, so I hand her the exam and say “when you finish, staple your work together and turn it in.”

My only complaint with today’s American university is when they are radicalizing students against the concept of relativistic mass.
Hard to express how bizarre and frustrating it is to hear these non-academics press their hallucinatory visions of what campuses are like. Truly no relationship to the reality.
Im begging the NYT to spend time talking to people who actually teach and work at universities. Especially ones that don't have billion dollar endowments.
My issues are AI use, crumbling infrastructure, vanishing staff, unfunded state mandates, a customer service model of education...

I remember as a kid having a book of NYT crosswords and it suggested if the clue is “African antelope,” 5 letters, you might pencil in “eland” or “oribi”. Finally got to use it on the final word today.

Science takes a team! At CWRU Physics, we’re bridging disciplines with Expansion Microscopy—embedding cells in gels and stretching them to study their inner workings. Here, Dr. Marouen Zammali optimizes hydrogels for maximum expansion.

Last night’s insomnia rabbit hole: Do mirrors flip images left-right? Why not up-down? Our brains seem to have a bias towards certain rotations, probably due to the symmetry and typical motion of the human body. And this can help explain why special relativity is so counterintuitive. (1/7) 🧵🧪⚛️

Let me try to explain why it's important to study the foundations of quantum mechanics. (1/n)
(Have to do some breathing exercises, b/c to me it's blindingly obvious that "understanding the most important theory in physics" is something physicists should care about, but apparently opinions differ.)

Nature (and @lizziegibney.bsky.social) take a more-than-usually systematic look at the greatest failure of modern physics: the fact that we can't even agree on what quantum mechanics says.
And the leader is an approach that is notoriously not well-defined. Ugh.

“Republicans look at the Republican Party, slowly digesting deep within Trump’s belly, and think, this looks good to me.”
I had some thoughts on the new WSJ poll and on what lessons it offers for the Democratic Party in the moment. www.pbump.net/o/the-party-...

Late Friday evening, the Wall Street Journal published a poll that fell solidly in the affirming-but-not-surprising category: the Democratic Party is viewed more unfavorably now than at any point in t...

After years of teaching quantum, I just realized that I have gotten this equation, at the heart of QM, backwards. It’s not saying that the frequency f of a particle’s wave function is given by its energy E. It’s saying that energy is *defined* as the frequency of the wave function. ⚛️🧪 (1/4)

Writing about how nuclear decay can be understood through the Many Worlds picture of quantum mechanics, and I'm stymied with confusion over which is the anode and which is the cathode.
...can I just call them both "electrodes?"
Just saying, electrochemistry is more confusing than QM.
