Macbeth: Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury
Signifying nothing.
Valley girls: Oh my god! That is soliloquy!

Does anyone here know anything about "Wallot Research"? They claim to run a summer math research program for high schoolers and undergrads, but their website doesn't say who the mentors are or what campus they operator from, and it's unclear if there is a stipend for participants....

I've never been interested in solving precisely stated hard problems. To me, the interesting part of math is finding beautiful structures that help us understand reality better - and clearly explaining them, so more people can use them.
If AI can ever do that, I'll enjoy talking to it.

People are posting positive male role models and I'd like to nominate Gene Wilder's Willy Wonka, but he didn't even set his Oompa-Loompa slaves free in his last will and testament, so I can't.

y'all I was approved for extra time accommodations today and it was super easy! I just lived with undiagnosed ADHD for 30 years, dropped out of school twice, suffered a lot of academic trauma, spent untold amounts on mental health treatment, and then took 16 months to fill out the paperwork!

I'd rather say
"The group of all rotations of a ball in space, known to mathematicians as SO(3), is itself a ball with each point on its surface glued to the opposite point."
If you're gonna scare people, I feel you might as well scare them with a puzzle they can actually chew on.
