New preprint from @tobyhandfield.bsky.social and me!
We analyze authorship order norms from two perspectives: (1) why do disciplines have different norms and (2) do those different norms affect what kinds of collaborations take place.

The Evolution of Scientific Credit: When Authorship Norms Impede Collaboration

I've had this puzzle box in possession for a few years now, but finally gave it a try! Nice challenge, with some fun little twists and turns. Good thing: I have two more!
This was the Cluebox Nautilus by iDventure, bought in a kickstarter (along with two others). Now to reassemble!

I used to have a puzzle related Twitter account. Lost the archive of it, apparently....
Considering doing one on here again, just don't know if I can keep on posting.

I was today years old.... Apparently the class of literature that I enjoy very much is called ergodic literature. Takes a while to get through a book: totally fine. S./Ship of Theseus (D Dorst & JJ Abrams) and House of Leaves (MZ Danielewski) were my gateways.
Any other fans here? Any tips?

Noted racist and Nobel Laureate James Watson, who stole Rosalind Franklin's data to try to deduce the structure of DNA first, has died at 97 as an unrepentant eugenicist and misogynist.

So unfair. When I hire a PhD student, they cost 30% (!!!) more if they happen to have been educated as a doctor, compared to their (often at least as competent, if not more competent for some projects) peers with a different Master's program. So unfair.

Casually browsing through the new Euclid Quick Data Release papers, I noticed that I should read up on the latest in Star Formation Main Sequence land... Does anyone here have a favorite paper on the current state of affairs for that, perhaps? Thanks in advance!
