There are repositories of math books on the net you can download. They have every level of math. From beginners algebra and calc all the way to differential geometry and graduate analysis texts. But are you really prepared to read something like Rudin on your own?
What was the position? I'm working towards my B.S. in Mathematics with a minor in Comp Sci and I'm wondering if there's anything outside programming that I can find related to math.
They've found a whole species of future mathematicians, though probably not the best. If they survived on pure amphetamines we'd be on our way towards a mathematical revolution.
The thing here is they are commercializing a cooling technique usually reserved for the hobbyist. I don't know about the energy saving claims, but their setup looks fairly organized. Interesting turn for a still niche cooling solution.
Also, purely observational studies? Why would these be news? Ok, observations that confirm a theory, great. But just observations and nothing else? Get back to me when you have real data.
How do you feel about hiring a guy with a BS in Mathematics and a Minor in CS? Undergrad here taking that route and one year off from grad wondering if it was a good idea haha
Maybe for lower division, as I stated in my post, this would be fine. After you get past all that stuff though, math takes on a new face. You are no longer tasked with "visualizing" the problem and then basing limits on that. The limits are arbitrary, the space non-Euclidean, and the work abstract. Visualizations here need only be minimal. A scrawled graph on a chalk board is MORE than enough to explain the concept visually. But if they want to play on the screen that's ok too.
I guess for computer science it can serve as an inspirational piece. To say, Hey this is why computers are awesome and here's what you could be doing with them.
For math though, you really need a pencil, some paper, the book and lots of time to get things wrong before you get them right. Calculation stuff for calculus, sure use the screen to create interactive bounds on integrals or what not. For analysis? topology? proofs? Get them some time to study and get them to ask lots of questions.
Imagine your PS3 hard drive dies. Your saves are online, or your PS3 is in for repairs. You can still use a buddies PS3 and login to an account and play from your last save. Even upgrading to a new console (of the sony variety) and still having your saves for backwards compatible games. That sort of service gives incentive to buy future products.
Of course there are problems. What if you don't connect your console to the internet? What if the servers hosting your saves go down? Would the servers act as a backup for your saves on your hard drive? (I think that would be a good idea)
I find that this sort of debate really lies to the side of entertainment publishing. Books that contain real educational material, usually, are so steeped in the universities that online piracy isn't even considered an issue. Thus, you can find older editions of classic texts online for most of the real "learning" material. Math, Physics, Engineering, Chemistry and Biology all have large collections online for download. The math collections are particularly deep and contain so much content as to not be able to understand it all. When you can find books on applying stochastic processes to financial markets, you've gone pretty deep into the rabbit hole. The DRM issue, as I see it, really lies in the realm of "popular" entertainment. The top sellers list on amazon, the prize winners and Oprah boasted "books". I think all the information that's important is readily available online in stashes so deep it takes a life time to understand them all. It takes two university years to get through both Rudins, let alone all the other math texts. I can hardly imagine the number of physics and bio books available.
In summary, let them have their DRM... I'm not really interested in the next Glenn Beck tirade or ghost written political horse shit that seems to plague the top sellers lists.
Seriously, my gripe here isn't about being spread over two pages, my gripe is that there is literally shit everywhere on that site. I have never seen such a "busy" lay out, with the facebook shit on the side and ads on the other, topped off with text ads in the middle of the article.. fuck that.
I'd rather science stay separate. The attitudes of the intellectuals doesn't necessarily lie parallel to the attitude of science. Their's is a world of "taste", "opinion" and "discussion" where as science is a world of "doubt", "evidence" and "review".
Computational, here specifically, refers to "finding the derivative" or "integrate this equation".
This is in contrast to "pure" mathematics which says "prove this function is continuous on the reals, then prove it's uniformly continuous on the interval [0,1]" or "prove this function is differentiable on any interval in the reals"... ect.
If your proofs were equations rather than words, then you were likely in a computational class.
I understand that, but there is a regular function for both.
sin(x) = (1/2i)*(e^ix - e^-ix)
cos(x) = (1/2)*(e^ix + e^-ix)
while this is covered in undergrad calculus courses, I was really happy when, in my real analysis course, we covered how e is defined. It was more to study the properties of series but still interesting, more interesting that a series converges to an irrational number.
e = Sum from 0 to infinity of 1/n!
so a sum of rational numbers converges to an irrational number... not too mind blowing if you take into account the Cauchy criterion and the fact that every irrational number is a limit point of the rationals... but it was interesting to me at least.
I can attest that "true" math is very removed from computation. The computational classes are all regarded as the "easy" classes. This is in contrast to the "hard" classes, real analysis and abstract algebra. Being thrown into real analysis after just one quarter of study in proofs is extremely rough going. If proofs were introduced as puzzles or just introduced earlier in education the whole of America would be better off for it.
My own motivations for being in math are for the challenge and because of the lack of concrete answers in calculus. Trigonometric functions especially are always treated as little boxes that magically calculate what you need.
apparently facebook doesn't support Opera? I visit it using this web browser all the time but when I click the link to facebook in the summary it tells me that facebook isn't cool enough to support Opera. Weird.
Really it should be under idle, it's just the fact that the dude forgot all about calculus and went back and remade the approximate method of integration. His hubris must be punished by way of an Internet meme.
Allow me to be somewhat cynical without angering the mods too much.
There's a reason people turn off the "hints" in IDE's, 3D modeling software, Word, Open office... ect. It's because if there is a problem, we'll go out and search for the solution. Now they want to put the daily hints behind the advent calender? oy vey!
Sorry, I was on the school network and forgot to login. At the time it was easier to post AC. Since I am replying I can't mod anymore but I guess the comment would have made more sense/been funnier had I posted using my account.
I've been here for a few years and I get mod points just about every week. They also gave the option to disable ads, which is cool. There is something about modding "+1 insightful" on/. though.... from my perspective it usually means "I agree with you".
blah blah blah... good post though, at least SOMEONE cares about AC.

That's why there is a link to the wikipedia article in the summary. So you can find out.

Sounds like a load of barnacles to me.

Buh bye Karma, it was nice knowing you!
excellent thanks for the reply, that's reassuring at least!

If I wasn't the GP i'd mod you up.

I like it sirs.
que privacy and/or anti-"cloud" /. comments NOW!
Who cares? Even for the religious, does this matter? Why would it matter at all?

Thanks editors, now I can justify my choice of a mathematics BS with a compsci minor to my parents!
On a more serious note, upper div math is no joke. The 1800's and 1900's had some serious brain power.

I'm not saying there isn't. Just that proof, usually, proceeds calculation and that proof is a bit more difficult.
I looked up the book, seems to be for graduate classes. I'm currently stocked up on books to read, I'll likely encounter it one day though.

In any case, at least math attracts the curious.

You may now proceed to mod me down.
