    > I bet i know more about computers than you do, from EXPERIENCE.

    You have experience with me? I'm sorry, I don't belive we've met.

    Believe it or not, I know a good bit about all of those things you mentioned, assuming you meant "data structures", though my area of research is elsewhere. Any thorough CS undergrad curriculum should include nearly all of those things, though all students may not choose to take all of them. Quantum computing has lovely math in it, which may make it unsuitable for a general undergrad curriculum. I am somewhat curious how much quantum computing work you did, if you don't like calculus that much, and you haven't even mentioned abstract algebra.

    The physics of charge and current -- which you claim to understand -- is rooted in calculus. Simplifications are used for chip design, becasue of the immense number of factors involved, and becasue we are reaching rather uncertain levels. Still, the physics is calculus-based, and you can't work out the most basic problems without it.

    >Please, no one Ive ever met whos a computer science in the industry has ever used calculus unless its too write a game and even then games dont use real physics so unless you want to make a sim of the atomic bomb explosions or work on writing a genetic algorithm to help boeing design new aircrafts what Math are you talking about.

    You've just listed several uses. Congrats. Simulations of all kinds use quite a bit of obvious math.

    Also, not everyone is in industry. Colleges and universities want to prepare people for all sorts of careers, including academia.

    >Math rigor? What is math rigor? yes you do problem solving when you write programs sometimes but 90 percent of writing programs is fixing bugs and using code thats already written, most algorithms are already there and you can just steal them, sure to be a GREAT programmer you need to be good at math but the average programmer they only know up to algebra.

    Many of the coding concepts you use have direct ties to mathematics. Recursion and inductive proof, for example. Type systems and second-order logic. (Look up the Curry-Howard correspondence, if you're curious. It's very pretty.) Knowing the background behind these things can help people program better, becasue they understand exactly why something is correct, and they can prove that it is so. Think of it as a human-centered version of proof-carrying code.

    >Discrete Math I dont have a problem with, I dont have a problem with Combinatorics, I dont have a problem with Algebra even, its calculus that I have a problem with, and Linear Algebra and the BS stuff they teach us which has absolutely nothing to do with computer science.

    Do you include abstract algebra in there? It's very useful in CS, especially where I am.

    Linear algebra is very useful for modeling. The advanced kind has more interesting uses as well, but you're probably not talking about that.

    Statistics is also useful, of course, but the point is that all sorts of math are useful, and perhaps you shouldn't complain quite so much about having to take em.

    >Give me an example of when you'll use math, the only math you will use is Combinatorics and
    some basic Algebra.

    You've given me some yourself. Crypto uses non-basic abstract algebra, generally, but also uses all sorts of other things, like linear algebra. A lot of computing involves modeling, which is right out of the linear algebra playbook, and also may involve all sorts of other things, like calculus. There are many more examples.

    Look, people are individuals.

    1. there may be some good reason they're avoiding you. maybe you smell. I don't know you, so I don't know.

    2. coding is not CS. it's a useful tool, but I've found math to be much more useful. I know somewhere around 7 languages pretty well, but I don't use them, generally, becasue I do math. Yet I'm in CS! Oh my! Something must be wrong here! And it's not very unusual to be able to superficially pick up similar languages from observation, hate to burst your bubble.

    3. women are differnt from each other, as are geek women. The guys I've dated had no complaints. I also think you're doing the other people around here a disservice in assuming they're recruiting becasue they want dates. Striving for equal rights and encouragement is often an altruistic pursuit. Don't ascribe one person's motives to everyone. Ans as for your comment about music people, that's rather common. In fact, at Berkeley, most of the Wind Ensemble is made up of engineers.

    4. some teachers suck. it happens. If you want to swap horror stories, I'll do so, but I'd like to point out that I know some that are a lot worse that have happened to women of my acquantance. I've found it varies a lot by school district.

    5. don't flaunt your scores if you're trying to prove that other people are dumb. Really. I got higher scores than you did, quite signifigantly higher in many cases, and I know that that says just about zilch about my intellegence -- the SAT's are justly deprecated. The AP's tend to be better, but vary widely between subjects. (and while I'm on the subject, the GRE's are pretty silly as well)

    Just becasue the women that you know don't point out that they're smart, doesn't mean they aren't. Perhaps you haven't met smart ones -- since there's a smaller pool, it's a bit restrictive. I would simply be very, very careful about assuming women are not as intellegent or as educated as you belive yourself to be. I personally know quite a few very intellegent women in CS. I have been doing rather well for myself as well, thus far.

    As for your statement that "for the first time, they're surrounded by a lot of guys who are good, know it, and can best them everytime," it's been my experience that a lot of guys have this issue. I certainly met a lot who expressed these sorts of anxieties, and when you go to grad school, at least at CMU, they point out to you that it's normal.

    Computer science is heavily math-based. Especially what I do. I'm female, btw, and I'm doing quite well, thank you. Have you not met any women, that you must rely on what you hear from others, and what you can determine to be likely inaccurate from the links in this story? Mathematical rigor seems quite necessary in most branches of computer-based work, though most of my experience has been in research.

    Software engineering, on the other hand, is not. Perhaps there wasn't a separate major for it, where you went. Still, math is helpful to teach you logic and new ways of thinking. Discrete mathematics and formal logic might have been more helpful, but calculus is generally introduced before those topics, for whatever reason.

    Wow. Where /have/ you been living?

    I actually am one of those people who keeps a lot of balls in the air at once, but it certainly hasn't prevented me from gaining rather deep knowledge in several subjects. Think of that as the ability to keep a lot of state in your head. While I'm reading a paper, I am also making connections to other papers I've read, research I'm doing, research I'd like to do, research my advisor'd like me to do, and other random things floating around my head.

    My grandfather's wife could be described as, well, a little ditzy. She is a very accomplished seamstress, though (ever heard of GunnySax?), and the sheer number of details that you need to keep track of at once for really nice clothes astonishes me (she's been teaching me). It's rather in-depth, although not the same sort of thing at all.

    Oddly enough, this has always helped me out in acquiring deep knowledge, since it connects to several things at once. It doesn't help me listen to lectures, since I get figety, and start working or writing poetry or short stories in class. It doesn't help me out in coding, since I get bored, only doing one or two things at a time, so I sing while I code. My officemates are very happy I'm not a systems person, I'm sure.

    Learning, like everything else, is very individual. How well you learn depends very heavily on how well you were taught to think, and if you were taught to think in a style the compliments your inner strengths.

    And no, I don't have any oranges up my jumper. They're real. And so is my knowledge.

    YMMV, of course. I was raised on a very balanced diet, and so that's what I like eating. I also have very specific food cravings if I get off balance "MUST HAVE BEANS NOW! AND TOMATOES! MANY TOMATOES!"

    Most people I know don't eat a reasonable balance and variety anyways, so the whole argument is just silly.

    It's no effort at all, I just eat what I want, I don't go out of my way at all. Mass-wise, this depends on what you eat, and doesn't have much to do with vegetarianism, much more to do with the amount of fat in your diet, as well as your calorie requirements and how far over them you are.
