Anybody want to join a Math Club?

I've found it's hard to teach myself math without an objective. If I don't have a specific question I'm trying to answer, my eyes just start to skip over equations, trying to get to the "good part". Pretty soon I've left the boring parts I know far behind. I've also skipped the less boring parts that i sorta know, and now I'm skipping forward even faster because I only understand half of what I'm reading. I wind up skimming the whole book, but not really absorbing much of it. I think I'd do better if I was planning on discussing what I'm reading with others.
So here's my idea: a math club. We pick a book, and we read it together. Every (week | two weeks | month) we read the next chapter in the book, and then we meet up and discuss it. Anything we can't figure out on our own, we discuss with the other members of the math club until we get it. The impending deadline of having to actually explain the material to other humans servs to focus and motive the reading.
Anybody interested?
Possible topics:
- Probability Theory.
- Lecture Notes on the Curry Howard Isomorphism
- Proof Theory: The First Step into Impredicativity
- The Geometry of Ordinary Variational Equations
- or anything else. math is fun!
EDIT: Benito made a facebook group so we can get organized and do this! see: http://lesswrong.com/r/discussion/lw/h5y/lw_study_group_facebook_page/

If you lack an objective, a good goal is to be able to solve national math Olympiad problems in the time allowed for the competitions.

Project Euler also is a good goal, but from more of an algorithmic/programming perspective.
From reading up on the math Olympiad, it sounds a lot like the competitions I went to in 4th through 8th grade. They taught me some quite useful skills - in college, discrete and combinatorial algebra was a breeze.

Your notation is the wrong way around. It's [Project Euler] (http://projecteuler.net). (without the space of course)
You also need the "http://" part so that the parser knows you're not pointing to "./projecteuler.net" or somesuch (omitting the http makes the comment break and not display the link or text at all, in this case).

Gwern's SR literature review suggests that answering questions is pretty critical for learning stuff. How about a collaboratively edited math test? Every club member contributes 1 question to each test, and every member takes the entire test (except their question).
BTW, LW math study has kinda been tried in the past; I didn't follow too closely and I'm not sure how well it turned out.
I feel like a mailing list would be a good idea for accountability and coordination. Most people here probably check their email more frequently than they check LW, and a mailing list would allow you to not spam LW with stuff that most LWers didn't find relevant (although maybe they'd want occasional summary posts). Maybe you'd like to create a google group or something and add it to the body of your post?

Those books are very expensive; either we'd need a pdf, or cheaper books.
Oh, you can make a pdf out of a real book for a dollar, with this site: http://1dollarscan.com/index.php

I may or may not have PDF versions of three of the four works mentioned in the article. I suppose you would have to PM me to find out.

It looks like we may have enough people interested in Probability Theory, Though I doubt we all live in the same city. I live near DC.
Depending on how many people are interested/where they live, it might make sense to meet over video chat instead.

Have you come to any DC meetups? They're pretty good. Though sadly, I think most people in the DC group who might be interested in doing this (including me) are already signed up to learn all the math they can handle in a formal program.

Yeah, I agree.
I think that we should make a list of everyone who wants to join, split them into groups of not more than 10 based on age, and every mini-group will decide what they want to learn and go at a pace that matches their background and ability.

Same here.

And here. Maybe we could start with probability theory, seeing as how that seems to be really central to this site.

Same. I'd be interested in trying this for a bit starting after mid-May.

I'd be interested as well.

The textbook thread is likely relevant here.

I would be interested in trying this, and one chapter a week seems manageable. To facebook!

There seems to be a lot of comments voicing general enthusiasm. I've not seen anything actually happening.
If you want to do a group study (probably starting with probability) then join up. We'll see how many people sign up, and then discuss particulars.

yeah I'm waiting for someone else to get everything organized I guess, maybe a lot of people are. Thanks for making some moves.

I was wondering about the ages of all the people who want to start this club.
Not that age really matters, I just wanted to know what kinds of people we have here.
How about we give our ages in a 10 year range?

How about everyone here who is at High School age message me, and that will be our group. I feel like we would be able to work better with people who were closer in age.
Of course, once you get older it doesn't matter as much, I think, but when your education is still in progress, we might have to do more background research.
P.S. I'm 14, and I would say that I'm turning 15 in 2 months but that sounds even more childish than just leaving it at "I'm 14". In any case, I think I'm capable enough of compiling a list, and what comes after will come after.

You can also chat with Patrick on #lesswrong, he likes helping people one on one or in groups.

I'd be keen on probability theory study, but have no maths background. My idea of a good intro to probability is ' Against The Gods, The remarkable story of risk' (Peter L Bernstein). So if that puts me too far behind the curve, no worries.

As Gokfar points out, we're probably going to need some kind of virtual blackboard thing. Google Docs has an equation editor, so that's an option, but I don't know if you can make diagrams in it?
Any ideas?

oh my god I would love to read Probability Theory with you guys. I'm almost two chapters in right now :) But I haven't read it in a while :(
