    I came "this close" to completing a math minor. I recently read Zero: The Biography of a Dangerous Idea [barnesandnoble.com] and became interested in picking up where I left off. Upon the recommendation of the math department head at the school I graduated from, I bought a textbook on topology [yahoo.com] and have been reading that at night before I go to bed.

    Any suggestions on what to tackle next? I really liked set theory, Boolean calculus, and so on (which means the topology book has been really enjoyable so far). My main goal is to be able to read the occasional article on higher math that filters through Slashdot, and the various interesting-looking physics books I find when I make it in to a city with a real bookstore (the best my town has to offer is a Hastings).

    I know that the real answer is "whatever I'm interested in", but I haven't been exposed to enough math beyond multivariate calculus to know what I'm interested in. Was there any class you took or book you read that made you look at the world differently or left you hungry for more?

      Given a good grasp of topology, and presuming you enjoy that, a couple of directions to aim for are Differential Geometry (which gets you a nice understanding of General Relativity, the shape of the universe, and that sort of thing), or if you want to head in a more pure direction, Algebraic Topology. Both those topics are "hard" in the sense that they may require material from other fields, advanced calculus for Differential Geometry, modern algebra for Algebraic Topology. Both are interesting topics in their own right though, and it should be easy enough to pick up a textbook on one of those for some background reading before starting in on your topic of choice.

    • Actually noting that your Topology textbook is from the Dover series, you might want to try Ian Stewart's Concepts of Modern Mathematics [amazon.com] which is a pretty good survey of the field, and would give you a nice sampling of the possible topics you could delve into further. If your not a mathematician, but want a good, and serious, explanation of some of the more advanced topics available, it's a great book.

    • I recently read and enjoyed "Mathematics" by Keith Devlin (revised and enlarged edition, March 15, 2001). Each chapter is a readable discussion of an important 20th century mathematical theorem: Four color map theorem, Fermat's last theorem, etc. Since so many important results have been found in the last century, it is not a short book.

      Once you see the major topics available and if you are still interested, then it is time to study a single topic from the undergraduate to graduate level.

      Short answer: it doesn't matter.

      Long answer: Mathematics is based on the basic rules we have inferred from observing reality. If somehow reality changed, then we would infer other basic rules.

      IOW Mathematics is about inferring basic rules and then building on top of these rules to come to (interesting) conclusions.

      There will always be certain basic rules as long as you are in a system where you can make differenciable observations.

      What you asked is a bit philosophy and a bit silly and unfortunately in the tone of anti-science ideologues (sorry).

      I'll explain:

      • I haven't seen any compelling proof that the cosmos IS mathematical.

        What is that supposed to mean?!
        Mathematics is not a religious ideology or cult. It is a though process. Reality simply "is". No matter what you're compelled to believe in, reality will not change.

      • ... happen in a post-mathematical phase of human understanding ofthe cosmos.

        what is that supposed to mean!?
        "post-mathematical" phase... that might be something somebody would say that has no idea what math is .... I already explained the basics on the top. As long as people will be setting up rules to live with reality, they will be practicing math. After that, it's all just a matter of who has the better math.

        If someone always gets shortchanged at the market-place of reality because their "post-mathematical" view of the reality of counting credits is farther advanced than the grocers, then they aren't going to get very much farther on the enlightment road. They also aren't going to get very far in a space ship in cold vacuum if they can't model harsh reality well. There is no such thing as debating, convincing or coming to a consensus with reality. It is does what it does and doesn't care what you think.

      • I'm so wrapped up in and surrounded by the mathematical model, that it seems irrefutable. But a look at history provides a proud narrative of ingenious folly.

        I really don't know what to think... are you being pleasantly open-minded and just wondering out loud or (I've heard this kind of talk before) do you have an anti-scientific agenda to push here?

        If our models or reality are wrong, then they will simply be adjusted to fit reality better. But the though process, the process of trying, testing, proposing, refuting, accepting or even simply calling BS will always stay.

      Netwons models of force and gravity turned out to not always work. We still use them because they usually work well enough. In the extreme cases Einsteins modifications of his models are used.

      Did science change after modifying the models? No. The process of science was to change the models because the modifications worked better.

      • I'll explain: * I haven't seen any compelling proof that the cosmos IS mathematical. What is that supposed to mean?! Mathematics is not a religious ideology or cult.

        As Einstein said, "I don't believe in mathematics. I believe in God. I trust mathematics." Science (or math) can never prove a theory definitively. The possibility of an alternative, better theory is always open. But the usefulness of a theory is based on how well it models known phenomena and this we can trust.

  • I appreciate mathematicians almost more than I appreciate math itself; only they would be able to develop the idea, first, of a quantity so large as to be boundless, and then hit on the idea that there are small infinities (like the sum of all real numbers between zero and one) and large infinities (like the sum of all real numbers.)

    For some reason, I was the only person in my math class who thought that was even remotely kickass. Hmm.

      I don't know how old you are or what level classes you referred to, but if you really liked it that much, then take some more classes. If you're good enough at it, then you will really like:

      Analysis, Number Theory and Function Theory

      Like any other discipline, once you grasp the basics , admiring the cleverness and hacks of the people in that discipline can be very awe inspiring.

      Math is an intimidating discipline, usually because many things have to be thought out thoroughly. Proofs can sometimes be very long. An incredible part is when you find or learn about alternative proofs. The ones that are only a few lines, that at the core contain a clever new idea that for some strange reason had eluded everyone for ages.

      In a way math and mathematical proofs are like lock-picking. In the worst case you have to use a drill or explosives, in the best cases - the cases that are always hoped to be found - the are ways to open the vault by listening, maybe using a magnet or string and giving it a final kick.
