Thinking about how a friend and I used to have "mail races". We would write each other physical letters and put them in the mail on the same day. Whoever had their letter arrive first won... I should she if we can get that going again

I forgot that I needed to come up with a few systems of equations that happen infinite number of solutions that can be parameterized for tomorrow. (I went kayaking with my kids instead....) Because of the time requirement I thought I would test out an LLM.

After 19 years I have entered the phase of writing warm up questions as poems. Today is my first limerick.
A whiteboard with the following limerick 

There once was a man named Descartes 
Who had algebra deep in his heart
For chance to be a hero
He solved 3x^3+2x^2+5x-2=0
Now it's your turn to start

This is the best way I have ever found to teach properties. Are numbers commutative in /mathbb{Z}/p? What does that mean? Algebra 1 kids definitely can understand it! Then suddenly maybe sprinkle a little cryptography in there and you are going wild

Wow. All those numbers are prime numbers. Isn't that cool? And hooray you've taught them ℤ/p and are getting into interesting math. This stuff can be made accessible and fun for kids, we just force kids to memorize times tables until they declare forever they are bad at math

IMO, senior faculty at top R1 institutions rushing to use AI to flood journals with papers before future students or early career researchers can have an opportunity is not just greedy, it's salting the earth of the discipline.

Why would anyone choose to dwell, for even a second, in the Kafka liminal zone of “by AI” or “with AI”? When you can do literally anything else, why would you do this with your one life?
