Our first featured presentation at the code4math.org Grand Opening will be featuring houseofgraphs.org — a database of *interesting* graphs, featuring metadata and search to help researchers in the field. Join us 9am Eastern on September 8! preview.scholarlattice.org/collections/...

I spent all day trying to prove an off-hand remark I need from a paper and I wasn’t able to do it 😭😭 #SabbaticalLife

Americans’ every instinct and reaction is deeply shaped by the constant threat of gun violence, in a way I think it can be hard to realize since we’re bathing in it so completely.
Prof Christelle Vincent (@xl772.bsky.social) reply parent
Guns in the US are so traumatizing. We saw a street fight today and husband was so worried one of the guys would pull a gun; that literally never occurred to me (bc we’re outside the US). In the end it doesn’t even seem that either men were hurt at all; in FL or TX it could have been fatal…

My PhD, on a student visa, took me 6 years to complete. This law would have made it impossible for me to complete my degree. Also, I met husband in my fifth year of grad school so basically my whole life would have been ruined by this.

Join us virtually next Monday and the following one!! Each day, one session begins at 9am Eastern/3pm Central European time, and the other at noon Pacific/9am Hawaii time, to cover as many time zones as we can so hopefully you can make it at least a little while! #MathSky

This is an incredible service that all Americans need and should have access to. Your feedback as a user (or non-user) can help improve the product and experience. It will also be a clear sign that the program MUST remain as a critical service. They will shut it down if they get the chance to.

I think before rolling the croissant up there was just a sheet of chocolate. I could not conceptualize of it as a baton at all!
Prof Christelle Vincent (@xl772.bsky.social) reply parent
Also each bite of the pastry must attain this ratio
Prof Christelle Vincent (@xl772.bsky.social) reply parent
For a chocolate pastry I have in my mind a specific ideal ratio of pastry to chocolate and it is the job of the pastry chef to both intuit and realize it in the pastry 😌
Prof Christelle Vincent (@xl772.bsky.social)
@johannamath.bsky.social I have an important update: I discovered the croissant au chocolat!! This one is maybe a bit too much chocolate (I’m only two bites in) but the chocolate is so well spread out!!

In case you need an ethicist's input: it's not only acceptable but, I'd argue, obligatory to say what you need to say to get a COVID vaccine. We have duties of care to each other, and particular duties of solidarity to those the regime wants dead, which supersede situational duties of truthfulness.

*gasps in horror* I’m with @clontz.org here! Yeah beating a video game is not “productive” according to capitalism but it doesn’t mean that the struggle to accomplish something valuable to the person who is doing it is not a productive state, or a state in which they learn!
