From mcnees@mastodon.social on Mastodon: Happy Rotating Black Hole Day! Roy Kerr submitted his breakthrough paper describing the spacetime around a rotating black hole # OTD in 1963. Physicists had been searching for decades for this solution to the field equations of Einstein's theory of general relativity. https:// journals.aps.org/prl/abstract/ 10.1103/PhysRevLett.11.237

From vcaston@zirk.us on Mastodon: I started an account at BlueSky because so many other academic # philosophers had signed up, but there is even less activity than here. I'm especially interested in # GreekPhilosophy but also # philosophyofmind and # metaphysics . Any others out there?

If a person wanted to download their data from # Twitter /#X and then create an artificial history of their timeline in # Mastodon (as if they had always been posting there - a migration of the timeline, if you like), any advice on how to most efficiently do that? Asking for a friend.

After a week in # Montreal for a conference ( # GUINEAPIG !) and then a week of vacation in # Sudbury , I returned to work at # SNOLAB today. Step one: inbox zero (accomplished). Step two: catch up with research students (accomplished). Step three: pick up the threads of project-related activities (in progress). Managed to also submit a letter of recommendation, re-read a…

From http://status.hackerposse.com/url/24557 on Mastodon: So, yeah. Loving the API for Mastodon. Have created a tiny Python program that will get the people I am following, look at a few parameters that I consider important (age of last toot, number of their followers etc.) Then it will prune these for me, cleaning up my following list to ensure I actually follow active a…

From mcnees@mastodon.social on Mastodon: And also David DeVorkin's interview with Vera Rubin for the AIP's oral history series. It’s a great read. http://status.hackerposse.com/url/24175. http://status.hackerposse.com/url/24555 -bohr-library/oral-histories/5920-1 This bit, especially, does a beautiful job of capturing the germ of basic research. DeVorkin asks Rubin what…

Had a lovely last day of vacation. Had a great walk in Rotary Park up in New Sudbury and a nice post-walk lunch and nap. Also, loved that # StrangeNewWorlds and # LowerDecks crossover episode.

It was a long process, but the good old # ChevyVolt was finally (a) fully imported to # Canada and (b) registered in the province of # Ontario this past Friday. The last hurdle was passing the import inspection, as one part of the car was found to be non-compliant with Canadian/Ontario auto rules. After weeks of searching and pleading with the dealership to solve the prob…

From JoshuahHeath@mathstodon.xyz on Mastodon: I vaguely remember seeing a post (it was on someone's blog, but I believe I saw a link on either Mastodon or Twitter) about a package for Python that made Matplotlib plots look like old-time journal pictures. Specifically, I think this was in the context of astronomy, but I'm not sure. Does anyone know of such a python package?

Had a wonderful time at # DynamicEarth in # Sudbury on a lovely rainy day. Especially liked all the hands-on geophysics, including testing conductivity and magnetism of minerals. https://chirp.cooleysekula.net/attachment/ccf2c835278f201c417dfb9696492eaa5229b04d89c236c55a910f462e18e199/view
