A statement by 40 Jewish faculty and staff on antisemitism and DEI at U.Va. As scholars and teachers, we know that dissent and debate strengthen our intellectual commitments and moral judgments rather than threaten them. We reject any attempt to deny these basic truths. 

I am not really active on here at the moment but I wanted to share this regarding my alma mater:

Since weโ€™re just unilaterally declaring things this week, Outlook is joining in and declaring it doesnโ€™t want to send any emails

This seems one of the (few?) good uses of AI. Although Iโ€™d want to really read the output carefully to make sure there arenโ€™t changesโ€ฆ

Every semester someone replies all to the teaching assignment email, but every semester itโ€™s a *different* person

I know it's a collision of two very different working cultures, but it's really annoying there's no way to automatically tell Dropbox to stop syncing .swp files

The idea is that writing text is faster on a computer but drawing figures is easier with a pen, and also that itโ€™s better for the students to see me sketching things (Iโ€™m teaching multivariable calculus)

Trying something new this semester for teaching: Iโ€™m making slides in typst but then writing on them with a drawing tablet while lecturing

This is related to working with rational functions as functions on the whole field: they have some singularities but you can just work away from those and composition, etc. still makes sense

z |-> 1/z is not a function on the complex numbers but it is natural to consider it to be a โ€œmeromorphicโ€ function from CC to CC (which means function defined except at nice isolated singularities)

11.01.2025 16:24 โ€” ๐Ÿ‘ 3    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Yes, BUT itโ€™s ok to extend the definition of โ€œfunctionโ€ to things that are not technically functions

Are you even allowed to add a subtle political message by including a prominent symbol of the government in the background?

I recently switched to using typst for teaching stuff and would also like to know the answer to thisโ€ฆ

I think thatโ€™s the easiest thing to do if you want the students to be able to mark where the questions are in their assignments.

I was thinking more about Dehn surgery but that's cool too I guess

Not to mention the Greek-speaking Eastern Roman Empire was around for another 1600 years or so...

02.01.2025 17:11 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

The fundamental issue with stuff like this is that "Greek civilization" isn't really a thing you can precisely measure. Does it count as "decline" if the Roman empire takes over but embraces Greek culture?

That's from the introduction about the history of Western mathematics. I'm hoping the shorter ones later (about stuff like the history of quaternions) are better

I like that the textbook I'm using this semester has historical sections! I do not like that it includes phrases like "After the death of Archimedes in 212 BCE the Greek civilization went into slow decline"

I think itโ€™s more about relative emphasis. The traditional approach to teaching math is a bit like drilling jump shots without ever showing anyone a real game of basketball.

Is phil as bad as math? Iโ€™ve had two papers take 30+ months to review, and one of those is still pending

...a more fair comparison is how ChatGPT performs compared to a typical math undergrad who has access to Mathematica and Google while writing the Putnam. And I think that the answer to that question is "eh, about the same".

Thread/rant over.
