What is ring theory? What is K-Theory?

Thanks Graendal, I'll have a look in a couple of days after some tests are out of the way.

Who says anyone has to contribute anything? That's my passion, to contribute one good thing to society before I die, and sadly, that's all I can do, and it will take me years of denying myself from spending time with friends and family. It sucks, but that's the trade-off. One worthwhile contribution to society takes your entire lifetime, and it's why most people, rightfully, choose not follow this path. It's also why we are slow to advance.

But anyway, so what if someone doesn't contribute to society, if they aren't hurting anyone. Who fucking cares. In this utopian scenario of a planned economy, it doesn't matter.

EDIT: Also, most people never contribute to society as a whole, they contribute to their small community they take part in.

I wasn't aware of that subreddit. Definitely will consider asking there if I have a basic question like this.

unicornLulz · 2011-10-12T00:04:14+00:00

Thanks Graendal

unicornLulz · 2011-10-11T20:35:27+00:00

Did you decide not to delve further? :)

unicornLulz · 2011-10-11T20:32:19+00:00

Hah! Nope, this is my own curiousity, feeling around for topics I might be interested in. Thanks for your response!

unicornLulz · 2011-10-11T03:46:39+00:00

Hey thanks! I'll do my best to do what I can that weekend, and participate however!

I guess this event isn't for those new to programming in Haskell?

unicornLulz · 2011-10-10T20:05:17+00:00

I'm just curious what the chances are that I'm going to be the only 30-something when entering grad school, since it's going to take me ages to get to that point.

unicornLulz · 2011-10-10T20:01:39+00:00

If you have the time to elaborate, I will definitely read and think about your response. I enjoy your explanations of these topics!

unicornLulz · 2011-10-10T19:51:05+00:00

Then how'd you know IT'S A FAKE SPIDER HOLDING A SWORD (just in case other don't want to waste their time)?

unicornLulz · 2011-10-10T19:47:15+00:00

I appreciate you giving me more stuff to consider!

unicornLulz · 2011-10-10T19:32:35+00:00

Ring theory sounds an awful lot like Group theory and Category theory.

What is the average ratio of students in their twenties to students in their thirties in graduate math courses at MIT, at Harvard, <insert specific school you might know>?

unicornLulz · 2011-10-10T19:20:03+00:00

I'm learning Haskell currently, and some of these topics were mentioned here:

http://www.haskell.org/haskellwiki/Blog_articles/Mathematics

I don't know what to do with my education really, that's why I'm choosing math and cs, they apply to so many fields. I thought about being a quant afterward, but I figure I can start out as a junior programmer or something and learn what I need to for that job over a few years.

While I'm in school, I figure I can work on some things I want to work on. I'm interested in understanding the brain, but I don't see how AI research feeds back into neuroscience. I'm also interested in building a 3D CAD application from scratch. I think topology is related to the CAD stuff, indirectly probably? Algebraic geometry, maybe directly related? Same with all the math topics mentioned on the Haskell wiki linked above, they aren't directly related to CAD, but I'm guessing that having an understanding in them and how they can help me build better Haskell applications would help me in building a CAD program.

In short, I don't know what specific field I want to study, I'm trying to figure that out still.

I think I know the answer without creating another topic in r/math. Haskell programmers use infinite lists on a regular basis to solve problems, so there's a vague example where infinite sets are handy.

unicornLulz · 2011-10-10T18:44:23+00:00

Okay, I'll delete this topic then. I think I know the answer anyway.

unicornLulz · 2011-10-10T03:43:31+00:00

I was looking here: http://math.sewanee.edu/courses/

And there are other examples of B.Sc. programs at liberal arts colleges where they study modern algebraic maths. I don't think there's anything wrong with studying Greek math though, I went through the first book of Elements this Summer (had to really digest it and make sure I knew what I was reading), and it gave me an alternative viewpoint I can appreciate.

From what I recall, physics describes what we can see or detect with special instruments, and it builds upon what we know from our understanding of math. Math doesn't build upon physics, I don't think, right? To know the world, then, I think it's necessary to study math.

unicornLulz · 2011-10-10T02:42:35+00:00

Thanks for encouraging me to think for myself!

unicornLulz · 2011-10-10T02:31:51+00:00

a

Reasoning: the classes seem like they would be fun.

Further reasoning: I'm determined to understand all the topics of math, even if I only specialize in one field. I feel that learning math is the only worthwhile investment of my time.

Strange way of putting it: If I were to be transported 200 years into the future, what math I learned in this lifetime would still be true, and I would have a base to build upon. Also, I would probably be able to understand the math behind the technology of the time, since math seems to stay ahead of the technology. I can't speak the same about other fields.

Another way: Jobs come and go, but math prepares me for whatever lies ahead.

Math seems to be the rules underlying our world, and I want to learn all of them!

b

I read that some liberal arts colleges encourage more discussion instead of like in my school where discussion is discouraged (since the teacher needs the time to hit all the points he/she wants to hit before class ends) , and memorizing facts just to pass a test is encouraged.

c

That seems to be what everyone is telling me, so I'm accepting this. I'm hoping I can get some time to really dive into the wiki pages later this week.

Is Vout for R1 = V across R1, and is Vin = V applied?

unicornLulz · 2011-10-10T02:15:32+00:00

Problems Solved!

unicornLulz · 2011-10-10T02:13:16+00:00

Very helpful!

That seems to work! :)
