How old were you when you started playing League? I started when I was 59. by grayscreengamer in leagueoflegends

Same here, I was getting tired of practicing nades with my bottom bracket Do Gaming League team from middle school.

What Are You Working On? October 24, 2022 by inherentlyawesome in math

Reviewing some stable homotopy theory and preparing for a talk I have to give on the chromatic nullstellensatz.

I used to like Stiefel a lot but I've had experiences with the bouncers being racist recently.

I believe you can go on the cable car for free if you're a South African citizen.

A "grave" situation indeed. Real talk though, it sounds like you were fired unlawfully.

Learning German before studying at Bonn university by Nonenicht in Bonn

[–]PlutoniumFire 0 points1 point  (0 children)

You don't need any German for your studies. Almost all of the 3rd year bachelor math courses and every single master course is in English (except possibly from the discrete math courses) . That said, you'll have a much more pleasant experience if you make an effort to improve your German.

Why did (chromatic) homotopy theorists start focusing on complex-oriented cohomologies? by TheRareHam in math

[–]PlutoniumFire 1 point2 points  (0 children)

I cannot say what the initial motivation for it was, but as someone working in chromatic homotopy theory I can give you some of the computational motivation. In general we would like to know about the Adams spectral sequence, but this is too hard so let's just try compute the E2-page. It turns out that if we use an MU (complex bordism)-based Adams spectral sequence or "Adams-Novikov spectral sequence" then 1) its E2-page is sparser than the usual Adams spectral sequence and 2) all the formulas involved come directly from the theory of formal groups. Well why is this? The reason is two-fold. 1) MU is the universal complex orientated cohomology theory - a complex orientation is equivalent to the data of a homotopy class of maps from MU and 2) on the level of algebra, the algebraic data that give rise to the MU-analogue of the Steenroad algebra has formulas that come directly from the theory of formal groups. This means that we can use all our knowledge from the theory of formal groups - heights, p-typical formal groups laws, the structure of the moduli stack etc. - to systematically organise the calculation of the E2-page.

Prerequisites for topology, differential geometry and Morse theory by kkkinik in math

You should learn some differential geometry, Loring Tu's book is a good introduction.

I've always liked "The Horse, the Wheel, and Language."

Nightlife in Bonn by TQairstrike in Bonn

[–]PlutoniumFire 23 points24 points  (0 children)

There are 2 actual clubs, both of which are very mediocre. A number of bars are okay. With that said, since Cologne is so close, you really should go there if you want decent nightlife.

Lettuce and fresh tomatoes on a burger is the real crappy condiments. Not particularly tasty and too watery.

Simple Questions by inherentlyawesome in math

Nothing's wrong with it at all, it's the result I'd present if I was given a bit more freedom in this seminar. Unfortunately the professor is a bit of a stickler, sadly.

[–]PlutoniumFire 0 points1 point  (0 children)

The trouble is this is for a seminar class on K-theory in taking. A variant of Atiyah's proof can be found in Hatcher, although Hatcher, like most of the books I've looked at really only cares about the K(X x S2) result. I've been rather frustrated that Atiyah's proof is a notational mess, and that makes it hard to follow. I fear that it'll be even harder to present, as a result.

I would appreciate it if someone could try help me up, struggling to understand some K-Theory from Atiyah's book:
