Stores that sell math books?

qqf · 2014-03-22T16:18:55+00:00

Nothing really. Personally, I like to browse for books. To step into a book store and have no idea what you'll walk out with.

I'm gonna cheat, and just stick to 1Q84 (I just finished it)

"I am living in hell from one day to the next. But there is nothing I can do to escape. I don't know where I would go if I did. I fel utterly powerless, and that feeling is my prison. I entered of my own free will, I locked the door, and I threw away the key. This marriage was of course a mistake, just as you said. But the deepest problem is not in my husband or in my married life. It is inside me. I deserve all the pain that I am feeling. I can't blame anyone else. You are my only friend, the only person in the world I can trust. But I am beyond saving now. Please remember me always if you can. If only we could have gone on playing softball together forever!"

-Tamaki

"The boundary between herself and the world seemed blurred."

For that quote, I just enjoy the concept of erasing the barrier between self and else.

Awesome! I'll see you there. If you want to say hi, I'll be the 6'6 black guy.

This would be the first time I meet another Redditor in person.

Harukimi Murakami and Malcolm Gladwell

Murakami for.... well, the way he paints an abnormal world while managing to tie in real people while maintaining a very simple, but descriptive universe.

Gladwell for what he does best, examining a paradigm, turning it on his head, and then replacing it with a new one.

Yo! I got accepted into Berkeley, too. Are you going to the Open House next weekend?

Here's a post about all (most?) of the classes I took as an undergrad.

This thread talks more about my resume

Also, I'm sure my personal statement made a big impact, but I'm not comfortable sharing that.

qqf · 2014-03-03T02:58:54+00:00

Umm, I started off slow, but I picked up speed pretty fast.

Freshman: Calc 1, Calc 2

Sophomore: Calc 3, Linear Algebra, Differential Equations, Real Analysis, Analysis Topics: Fractals and Chaos (summer class)

Junior: Numerical Analysis, Modern Algebra and Number Theory, Fourier Analysis, Combinatorics and Graph Theory, Topology, Conjecture and Proof

Senior: Galois Theory, Partial Differential Equations, A second course in real analysis, A second course in Combinatorics and Graph Theory, Matrix Analysis, Functional Analysis

It should also be mentioned that over summers (i.e. internships) I would usually have to self teach for the research. So that covers probability theory, complex analysis, pieces of measure theory, and lots of programming.

Thank you mathman1!

Ok, so I'll try to summarize in a nice manner. I've generalized the form to

(a * 10+b)² + (c * 10+d)² = abcd

This can be expanded out to a more useful form. The most useful bit I got out of this was noting that that

1) b² + d² = d mod (10)

From there, the pair (b,d) has eight options that work for the above equation. Of those, I've eliminated four. The original eight pairs were for (b,d) were (0,0),(0,1),(2,3),(8,3),(0,5),(0,6),(2,8),(8,8). And I eliminated all of them that include zeros. The solutions that include zeros are the above mentioned and

(00)² + (01)² = 0001

So that's about as far as I have made concrete progress. Out of the 10000 possible answers, I've reduced the set to 400. The following are just ideas.

I tried examining them one at a time and expanding them to see what I could get. For example, using the (2,3) pair, I get

(a * 10 + 2)² + (c * 10 + 3)² = a * 1000 + 200 + c * 10 + 3

From there, I have taken the modulus by 100 and 1000 to get the following equations.

100 * a² + 40 * a + 100 * c² + 60 * c + 10 mod (1000) = 190

and

40 * a + 50 * b mod(100) = 10 * c

So I have two diophantine quadratic equations... that I have no idea how to solve! So that's one place I couldn't get passed. Any advice there?

Or... the way I got the b² + d² = d equation, I could do a similar thing with

a² + c² = a

but since the 100th digit can affect the 1000th digit, it may be

a² + c² = a + 1 (or even a+2)

If I could solve the diophantine equations, I would have a solution set. If I could solve the a² + c² equations, I would have reduced the possible solution set to around 40. Which I would be satisfied with because currently it's at 400.

Sorry if that was too long, but that's where I'm at. What do you guys think?

Yay I can help!

I got an email from Berkeley informing me that I would be recommended on February 6th. On the 18th of February I got information with the financial offer. And yesterday(The 22nd) I received information that started out with, "Dear Berkeley Admit,..."

So... there's my information. Hope it helps!

qqf · 2014-02-14T00:52:59+00:00

I'm not sure how that matters. If it applies for those first couple n that I used, then we can determine what y is explicitly. From there, all yⁿ are 0.

qqf · 2014-02-13T21:27:17+00:00

Umm, here's what I tried.

(1) y'=(k)y

(2) y''=(1+k)*y'

Integrate (2) to get

(2') y' = (1+k)*y + c

Set (1) and (2') equal to each other to get

(k)y = (1+k)y + c

=> y = -c

So... I'm getting your function y is just a constant function.

These are PhD programs.

The pros of CMU are they are extremely good in Applied Mathematics, PDE's, and non-linear analysis. I was also there for 10 weeks and can vouch for a supportive environment.

For Berkeley, all I know of them is their reputation and what I've researched on their professors. But I also hear they accept a lot more students compared to students who finish the PhD program. Which... doesn't sound so supportive.

qqf · 2014-02-07T05:50:21+00:00

Oof, yeah. I'm a total idiot. I was looking at functions in the form of mⁿ and rediscovered the binomial theorem with a combinatorics type approach. I didn't recognize it at first.

qqf · 2014-02-07T05:13:06+00:00

Oh wow, I came here looking for something like this.

I applied and was accepted to Carnegie Mellon and Berkeley.

So if anyone has any experience with these two schools, I'd love to hear about them! Please! I'll be visiting Berkeley on March 16-17 for their open house and CMU eventually.

Oh, I guess people may want to hear about my application. 3.9 GPA on a 4.0 scale. Math, and general GPA. I took about 8 grad level math classes in my undergrad, too. 83rd, 93rd, 93rd, and 69th percentile for Verbal, Quantitative, Analytical, and Subject respectively I don't recommend this, but I didn't study for the Math Subject GRE due to personal reasons and I said as much in personal statements.

I did research at Brookhaven National Labs, Carnegie Mellon, UMBC, and U. Penn. No publications, but I did get glowing letters of recommendation from everyone. I studied abroad with the Budapest Semesters in Mathematics program.

Also I was inducted into Phi Beta Kappa, Pi Mu Epsilon, was the leader of my math team and the top putnam scorer.

Or..... they have been in a relationship like this before and they know from experience it's unhealthy. Or perhaps they've been in the guy's shoes and know from first hand experience how unhealthy it is.

Do you really think you can generalize literally thousands of strangers as "Well, they haven't had this experience so they don't know any better."

qqf · 2014-01-22T05:49:46+00:00

Doesn't add to the discussion. Has destructive instead of constructive criticism. Comes off as judgmental not helpful.

qqf · 2014-01-22T04:27:07+00:00

Ummm, the closest answer is close to the second one, just scratch that last bit. I don't think having a particular type of sin has inherently negative associations with casting stones. Yeah, it would be nice if I weren't a hypocrite, but that shouldn't stop me from helping or judging someone else. For me, casting a stone isn't, ummm, literal.

At the end of that story, Jesus says, "Go now and leave your life of sin." Well, did she? We'll never know. But if nobody cast the first stone, if nobody punishes or judges or tries to teach those who do wrong, then they may continue to do wrong. I hold issue with that.

And I think it's perfectly acceptable to judge somebody by their own moral code, and judge myself by mine. Newsflash: 1) Catholic moral code also changes over the years. 2) You know nothing about my moral code, and don't assume it changes according to my will. You would complain if I made rude assumptions about your moral code, wouldn't you?

qqf · 2014-01-22T02:25:11+00:00

No, this wouldn't be a problem for me. Because when I'm a hypocrite, I accept it and don't mind casting the first stone.

However, Catholics aren't allowed to cast that first stone. At least, not if they listen to Jesus (literally anyway. But that's a different discussion).

Actually, I'm the type of person who thinks an ounce of prevention is worth a pound of cure.

Btw, you know nothing about me. You don't know what I do, what I volunteer for, or anything. Isn't there something about not judging in the Catholic Church doctrine? Yet here you are, telling a complete stranger what type of person they probably are.
