Never heard of Tao before. You were lucky there. For some reason topology was the one math course that had me floored. I passed it but felt utterly lost. I only passed because I followed the logic, the theorems and proofs, but I was in a daze in terms of grasping where it was going and why. I figure it was because of two factors: (1) the class was huge, probably a couple hundred, maybe more and (2) I suppose the guy teaching it lacked the ability to engage his students. Oh, and I suppose the text book was no particular help in countering (1) & (2).

"Probability." I took a statistics class, upper division, I believe, maybe 101, and it was a comprehensive introduction for people comfortable with math/science and got an A. I don't remember a lot, but some basic stuff. It's a great field, of course, in spite of what Mark Twain said about statistics. He never studied it, only saw what was said in newspaper columns, I assume. I don't know the state of statistics in Twain's day, but I suppose there was some sophistication by that time.

You sure it was topology? I never had an upper division math course at UCLA with more than maybe 45 students in it, and the topology course had maybe 20. It wasn't a required course for a math degree, as you had your choice of differential geometry, topology, or plane geometry to fulfill the geometry requirement in the degree when I went there.

100% sure it was topology (this was at Cal) and the class was by far the biggest I had in math. It was in a space best termed an auditorium. I would have needed binoculars to get an idea of what the professor looked like.

Wild that an upper division course would be so big. Kind of glad I didn't get into Cal then and went to UCLA instead lol (Berkeley was my first choice school, UCLA my second).

Back to Tao though, I'm jealous of the people who took real analysis with him, as he wrote a book that builds all the way from the Peano Axioms to Lebesgue integration. We used a book called Baby Rudin which I had a love-hate relationship with. Hated the book because every proof tried to be slick instead of straightforward. E.g. instead of proving the mean value theorem f(y)-f(x) = f'(c)(y-x) for some x<c<y it proved (f(y)-f(x))*g'(c) = (g(y)-g(x))*f'(c) for some x < c < y for f,g continuous on [x,y] and then says take g(x)=x in the previous theorem to prove the mean value theorem lol. But the problems were amazing in Baby Rudin.

I'm still laughing over the post you linked about gamers asking if Nintendo could put up a new factory (in Ohio of all places) in 3 months time.

How can a country with this level of awareness even survive?

We had a vivid example of how non-flexible supply chains were back in 2020-21 and people just simply decided to memory hole it along with all the mass death.
 
Imaginarem money vanishing from "existence" and reappearing again by the trillions in the span of minutes due to two tweets...

You know, all our lives would be better without this "market".
 
My friend and I put puts on the NASDAQ ETF when it was up today. That Trump tweet about China tariffs going even higher should really do well for the tech sector. It should be taking a nosedive

I still don't fully understand puts or how they work. (options confuse the hell out of me)

So you enter into a contract for say QQQ to sell it at today's price within 90 days? And it's still your call whether you finally sell or not?

Like say QQQ today is 440.. but if it tanks to 330.. you can still sell it at 440?

Is that it?

Imagine putting something on a boat and you have no idea if the tariff is going to be 0% or 200% when it gets there. A lot of orders will simply not happen now.

I had a friend buying a camper from Canada. Put the order in almost a year ago with a delivery date of Q1 this year. He spent the last 2 months worried he'd have to either pay a $9k cancellation fee or an extra $15k in tariffs. Fortunately he was able to take possession but even then it took the company he bought from 3 days to determine if he really could get it without paying tariffs because everything was changing so quickly and the rules were all over the place

Yep and in the current environment he probably would not have made the order in the first place.

I know the basic premise of them, my friend is the one who plays this stuff and knows the intricacies of them. We chatted last night, and I said I want to place puts on the S&P500 ETF or the NASDAQ ETF, your call. He put them on the NASDAQ etf. I have no idea how long he put the contracts for or any of that. All I know is the more it goes down, the more money we can make. Debating right now when to call them.
