The 120-cell incorporates the geometries of every convex regular polytope in the first four dimensions (except the polygons {7} and above).
120 is also the amount of days left until SRS.

I'm happy to see the redesign of the Jackson Street Bridge coming together at last! It's been several years in the making.
There's a post that prevents cars from entering the new two-way bike path, and several parking spaces are here to lure photographers from parking in the bike lane.

“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

As a young Assistant Professor, I attended a lecture by Watson at UT Austin. I was excited, I mean..DNA… I learned no science from his talk, but did learn he was a flaming sexist and racist. Worst of all, it went unremarked upon by my colleagues and the field. My lesson: this is what we face.

I read The Double Helix as an undergraduate. I was a science major at a women’s college taking molecular biology. Our professor taught us that Watson & Crick screwed Rosalind Franklin over.
So I read the book to learn more. I’ll never forget how reading this passage made me feel.

![“By choice [Rosalind Franklin] did not emphasize her feminine qualities.. There was never lipstick to contrast with her straight black her, while at the age of thirty-one her dresses showed all the imagination of English blue-stocking adolescents. So it was quite easy to imagine her the product of an unsatisfied mother who unduly stressed the desirability of professional careers that could save bright girls from marriages to dull men.. Clearly Rosy had to go or be put in her place. The former was obviously preferable because given her belligerent moods, it would be very difficult for Maurice [Wilkins] to maintain a dominant position that would allow him to think unhindered about DNA.. The thought could not be avoided that the best home for a feminist was another person’s lab”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:opitzjj6oapo6y3cr5ipwfdu/bafkreibj5i6hdhoinpdbtx5ij7e56lz5v6zg6d6aompkuvrxrdnmkfvj2m@jpeg)

Researchers have unveiled a quantum algorithm that could lead to quantum advantage. Using a time-reversal procedure, the algorithm calculated how quantum information spreads through a many-particle system. A classical supercomputer would take 13,000 times longer.
