Source for this particular quote? I haven’t heard it, and it doesn’t jive with other things he said.

Please look up the influenza epidemic of 1918-19 to understand that the CDC not selecting strains for next year’s vaccines sets the stage for a public health calamity that will, without doubt and at bare minimum, catastrophically and directly impact people you know. This is a five alarm fire.

Meet the man who single-handedly tracks every spaceflight mission ever For more than 40 years, Jonathan McDowell has tirelessly catalogued the space industry. Now he is planning to retire, and looking to pass on his extensive collection of knowledge

All the best to @planet4589.bsky.social with his retirement. Will gladly welcome him back to the UK!

Because of four decades of bad faith narratives by rich folks who want your taxes to go up and their taxes to go down, most folks don’t know this: career federal workers are heroes who work extremely hard every day and go above and beyond all across America to improve your lives.

The people who voted for Trump because they thought he’d pull the U.S. back from foreign entanglements and overseas adventurism are really among the prime suckers of our era.

If they "are serious about slashing NSF, the result would be catastrophic, the same program manager warned. Cutting the $10 billion grantmaking agency in half would β€œgut the intellectual center of U.S. leadership in science and technology,” the official said. www.eenews.net/articles/sci...

Reassuring scared colleagues that their third shift work over the years supporting their community is valuable and good and they should get to own that, and I hope they can again.

"pip install sk8plotlib" if you want to give it a try!

Note that rescaling the skateboard to the data in the plot isn't supported yet, & the skateboard always spawns at (0,0) still, so if you have large or small numbers (or a log plot) then it won't like it

Recently talked to a student who admitted to using ChatGPT as a study device - by feeding it all of the class lecture slides and having it generate summaries. So now OpenAI has ownership of all the slides my co-instructor and I created from scratch…

 Spent pretty much the whole afternoon playing with JWST images.  Managed to import different colour channels, learnt tons!  That article was great! Thanks!  Cant believe this data is just there for anyone to do what they want!

Well, this is neat! People are already using my step-by-step guide on processing JWST images and producing results after I published the article yesterday.

And look, they are following the way I outlined to pay proper credits to the science team πŸ₯ΉπŸ₯Ή
