Pedro the #Math Cat 🐈 wants to know why it's taking me so long to grade these papers.
#cats #CatsOfMastodon

Because he's sitting on both the stack of papers and the answer key.

Yay, got nerd sniped with another math problem. I made it a smidge more difficult than it should've been, but I'm happy that I got the correct answer eventually.
The problem: Given `1 / tan(x) = tan(1 / x)`, solve for `x`.

Nerd sniped myself this time: after getting sniped yesterday with showing that for primes `p >= 5` that `24 | p^2 - 1`, I decided to look at primes `p, q` where `p, q >= 5` and see if `24 | p^2 - q^2`.
#math #nerdsnipe

Given primes p and q where both p and q are greater-than-or-equal-to 5, prove that 24 divides p squared - q squared.

If Gauß had had an electronic calculator, would he have proved better and more theorems or weaker and fewer?
It would have spared him days and days of rote calculation but maybe this calculation was prerequisite for insight?

Pedro the #Math Cat 🐈 knows that everyone has to say "big stretch!" even when it is just a medium stretch.

More importantly, stretching is a healthy activity even in medium amounts.

OK, but the results are still just paper links, not what the LLM thinks about them. So the only thing that changed is that it is much much slower now?
Maybe the LLM just formulates a query to the old scholar? Too many layers of "oh how can we build an LLM into this"...
OK, nobody in #math uses Google Scholar like this anyway. We only use it look at publication records of people and do reverse citation search (which papers cite this one I have).
