Right, enough of James Watson - who's a senior academic you've met who's been an utter delight?

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.

Excited to attend the @astrosociety.org gala tonight & receive the Nancy Grace Roman Award! I read about her life & career on my way here. Did you know she was responsible for making NASA data archives public so that everyone could benefit, not just PIs? Such an amazing impact on our field. 🔭

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)

Absolutely amazing: they've got so much solar in Australia that they need more people to use more of it, so the gov't has instructed energy retailers to offer *at least three hours of free power* during the middle of the day.

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.
