    What is the significance of generating functions in canonical transformations?

    Thank you for your help. Regarding writing the generating in terms of the old or new, I still don't understand why it doesn't work. Sure, I will have to inverse the equations, but what difference does it make? Given a generating function, I know the explicit transformation, so why can't I just...

    What is the significance of generating functions in canonical transformations?

    I'm not sure I understand the use of generating functions in canonical transformations. In particular, why are there four basic canonical transformations? It isn't true that any canonical transformation is one of the four basic types, so what makes them special over any other transformation...

    Euler's Method Error: Derivation & Estimation

    I understand how the (local) error for euler's method of integration is derived from the perspective of the taylor expansion and inequality. However, I don't really see why taylor's equation needs to be invoked, since the euler method can also be derived as a tangent line approximation. How then...

    Where can i get voltage transformer

    I need a voltage multiplier to up DC voltage. Is there any household appliance that will have it that I can rip it out of?

    Finding the Right Math Book for Me: What is Mathematics?

    I'm not entirely sure what book I want, even what subject it would be considered as...which is why I'm here. My mathematical knowledge is dismal. I want some kind of book that will cover the very fundamentals rigorously. I don't want a high school textbook which will just bs its way around, but...

    So You Want To Be A Physics Game Programmer ?

    I don't know why or how CS became closer to CE and EE. CS began as a subtopic of math and logic, and it should have stayed that way. Now-a-days, it seems like more emphasis is placed on learning the language and dealing with the bs that software has become, rather than learning the math. It's...

    Physics at Columbia, Brandeis, Brown: Grad School Chances

    Yeah, it's mainly the graduate school placement rates that I'm worried about. Brown from what I've heard is suffering on that front. But I've heard nothing about columbia, brown, or cornell.

    Physics at Columbia, Brandeis, Brown: Grad School Chances

    AN IMPOSTER! HOW DARE YOU? That's too bad that columbia doesn't have a physics program. It's a prestigious college. As far as brandeis, they give 50 full scholarships and I received one, so there is a lot of prestige associated with it.

    Physics at Columbia, Brandeis, Brown: Grad School Chances

    How's physics at Columbia? It seems that Cornell has a more well known physics program, and there's not much said about Columbia. And what about physics at Brandeis and at Brown? Also, what are my chances for an awesome grad school going to a school like Brandeis that isn't ivy? I'm not sure...

    How Can I Combine Math and Linguistics in My Academic Path?

    Actually, a lot of the people I know who are doing math are also doing linguistics. Math and linguistics together seem to be a relatively common combination.

    Where does the formula for dtheta in polar coordinates come from?

    Thanks PBRMEASAP! But I'm a bit confused by the second part. You write that i can simply add theta1 and theta2 together to find theta. How exactly do I find the theta1 and theta2 that arise from dx and dy?

    Where does the formula for dtheta in polar coordinates come from?

    For this diagram: http://ananth.ath.cx/coag.jpg The textbook gives the formula for dtheta as (x*dy-y*dx) / (x^2 + y^2) assuming that r' ~ r. How is this formula derived?

    Nature of Waves: Why Do They Form?

    T. Roc, I am aware of that the sound wave is not a sine wave. That is what I was clarifying my post, as the OP seemed as though he believe that a sound wave is like a sine wave. Moose

    Nature of Waves: Why Do They Form?

    I'm not entirely sure, but your post seems to imply that you believe that the particles are moving up and down to make a sine wave, like a wave on a rope. This is not how a sound wave is transmitted in air. A sound wave is a compression wave where the air particles transmit the wave by squishing...

    Testing MIT Admissions: Successful Applicants Without Perfect SAT Math Scores

    I'm not complaining that I didn't get in. MIT was never my top choice. It's just that, like many other people said, admissions is random, and sometimes seemingly illogical, and I've seen too many miserable people whose dreams and aspirations have been shattered completely. Don't do that to...
