Recorded during Spring 2021 Math 222B (Partial Differential Equations) and Math 279 (Random Perturbations of Non-Self-Adjoint Operators)
-
1/19/21:
-
"This is... to use the F-word... fundamental, in this subject."
-
"This is the problem with doing computations in real time. It's like watching baseball."
-
1/26/21:
-
"That's a good point. Oh, goodness... sorry. Ah sh*t!"
-
1/28/21:
-
"By the way, am I almost out of time?"
-
Student: "Yes, you have negative 1 minute."
-
"Ah. May I have positive 2 minutes?"
-
"This measure is like the office upstairs in a Kafka novel."
-
2/2/21:
-
"You know, somebody could say maybe only finite sets exist, in any case. Let's face it."
-
2/16/21:
-
"Matrices are zeroth order differential operators with constant coefficients, but I still don't think I can get away with calling this a PDE course."
-
2/18/21:
-
"Spectral theory is trivial, and should not be taught."
-
2/23/21:
-
"PDEs do exist, you know..."
-
"By... Taking... Subsequences. See? That's BTS."
-
2/25/21:
-
"I noticed you were amused by me using BTS last time. So I looked it up on google. And I suppose I found out that you are a K-pop fan."
-
3/2/21:
-
"For any q, this blows up. ...Okay, well, really any q bigger than 0, in case you get some Bourbakis to look at these slides."
-
"Yes, exactly. We want to know if the converse is true. I can see you've been studying logic."
-
"We're just physicists, so we don't care at all about domains or such silly business." - After 2 lectures spent exclusively discussing domains.
-
3/9/21:
-
"Who played Nash in that movie? V, you must know, you're the BTS expert."
-
4/1/21:
-
"It's not a set, it's a category. That's a set of points with multiplicities."
-
4/6/21:
-
"You're really easy to bamboozle, Y" - After claiming 5/6 is between 3/2 and 2
-
4/13/21:
-
"Who the f-triple-star is Jackson Pollack?"
-
"This is not an art class!"
-
"I have a graduate student, and I'm not going to throw him under the bus. Very smart guy. But 6 months ago, I asked him to complete some squares, and every week he has another excuse as to why he hasn't completed the squares."
-
"This little factor right here has caused an untold amount of grief to generations of asymptotic analysts."
-
"Showing o(h), that's a dinner in a 1-star restaurant. Showing O(h^infinity), that's a dinner in a 2-star restaurant. Showing it's actually an eigenfunction is a dinner at a 3-star restaurant. That's the reward for these problems."
-
"So and so proved that 1-star restaurant implies 3-star restaurant, but I couldn't give him any dinners for that proof."
-
"Terry Tao put on his blog that if someone solved, this, he wouldn't be buying them dinner, but he would fly them down all expenses paid to sunny LA."
-
"I don't recommend you try to solve this - not because I don't want to spend money on a fancy dinner for you, but because I have no idea how to direct you."
-
4/22/21:
-
"I guess this is proof by intimidation. I don't want to just intimidate you into believing this here."
-
"Sky...scraper...sheaves.... Ooh, skyscraper sheaves on nLab! What the hell is nLab?"
-
"Sorry, I'm just reading about sheaves now. Maybe I should not spend the office hours... uhh... uhmmm..." Gets lost in reading again
