I have a terrible sense of direction. That's probably why I got a PhD.

Hey #ChemSky - I'm putting together the #Newscripts holiday gift guide for @cenmag.bsky.social. Have you given or received a great chemistry-themed gift recently? I'd love to know about it and maybe include it on our list. Here's last year's guide for ideas:

I’m impressed the article restrained from using the word AI and opted for machine learning. I remember the 90s when they called them neural networks haha.

I want my mvp to sleep and so does he.

The Bills should be banned from playing at 1pm. Josh needs his sleep. #BillsMafia

Last square number date until 2026 - happy 9/25/25 to those who root for days like this. (Don't hate the joke, hate me for making the joke.) #MathSky

Donald Knuth: Mastermind (algorithm solver — what most people now know as Wordle)

Michael Kinyon @profkinyon.bsky.social · 15d

Essentially what Donald Knuth argued in the March 1998 issue of the Notices of the American Mathematical Society. His letter is reproduced here:

To prove the power rule for derivatives, you don't need the full binomial theorem, just that

(x+h)ⁿ = xⁿ + nxⁿ⁻¹h + O(h²).

I think that's a much easier sell!

Found this note to redo something. It made me chuckle because I had to do redo.

Yes I made a homemade ‘Happy Perfect Square Day!’ pin to wear today. Do something that involves a right triangle today & let me know what it is. #iteachmath #mathstoday

Finally broke down and picked up the base M4 Mac Mini. I've been lifelong windows. The device integration is what sold me and whoo it's amazing. Great value product so far, now it's time to push it.

I used to be obsessed with #energy and #sustainability in the 2010s and dove deep into the subject back then. I co-wrote 3 books on the subject. My last one on energy efficiency was picked up by Elsevier. I always thought it was priced to never sell. Oh well. shop.elsevier.com/books/energy...
