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

My coauthor is absolutely cracked. She comes up with crazy ass combinatorial formulas like these. I dream to be just as good at this one day...

Anyone else still using chalk? I am one of the last at my high school and love it.
If only I had sliding boards…one can dream.

Let V be a vector space, dim V = d.
The map V⊗V→S²V induces
f:V→S²V⊗V*.
If d=2, coker f = (canonically isomorphic to) S³V⊗Λ²V*.
If d=3, coker f =Λ²S²V⊗Λ³V*.
This is a key step in a paper I am currently writing.

Math literacy requires more than just calculations.
Whether they’re answering complex problems on an exam or trying to understand the terms of a home loan, students often need to use “reading comprehension, along with math skills” to succeed, @drcelita.bsky.social writes.
