I have been studying physics for two years. (High school physics supplemented by the Feynman lectures, as well as an algebra based freshman course) Lately, I've been looking of various derivations of things (escape velocity, kinematic equations etc.) and wondering which is more elegant in a...

if you were to write velocity as a function of either area or length you could use calculus to maximize the escape velocity... I don't know how hard that would be though

Sorry, I mixed up taylor and mclaurin series

You have to know how to expand the Maclaurin series about (x-a) using derivatives, and the common taylor series for sin x, cos x, ln x, e^x, and geometric series. You also need Lagrange error and series convergence and divergence tests, specifically the integral test, p-test, alternating series...

I'm curious as to how these wouldn't be useful to a physicist? Do we not have biophysicists, geophysicists and physical chemists? Furthermore they broaden the horizons and experiences in terms of what a person may want to do. If you like physics, study it, if you find that you don't like it...

I'm curious as to how this changes apparent observations of the observer verses a stationary one. Not in terms of different physical phenomena, but in terms of how the geometry changes when moving at a constant speed, in short, what changes to the manner in which the moving observer makes his...

It just seems better to use the reasoning which is more widely applicable to more situations, that's just my opinion, and I'm by no means qualified to judge one way or the other.

It wasn't a violent argument (at least from my perspective, I can see how a teacher could be upset if the student insisted he was wrong) I thought it could be argued both ways, and he was pretty sure that I was wrong and that he was arguing the correct way. I was just curious as to how other...

Hello, I was attending a physics discussion on fluid dynamics (fairly basics concepts) and the classic buoyancy demo came up. (A test tube is inverted and allowed to be filled with enough water to float with the volume of air trapped in the tube, the test tube is inside a larger bottle which...

if this holds then why can't I get in helicopter and hover above a point while Earth turns below me? Is the rope attached to the pad or just really really long?

and those requisites would be... I have calculus through integration (we just finished transcendental integrals) I also have a firm foundation in physics, mainly in mechanics

I just ordered road to reality, I'm apprehensive about starting it... I taught myself differential calculus this summer using a text and "Calculus Made Easy" (which I would suggest as a supplement to the text) Anyway, I would really like to know how rigorous Road to Reality is... Is it a...

How can this work? Its an indefinite integral and the answer's definate. One's with respect to m and the other t. I'm sure it doesn't change the u substitution, but shouldn't everything be noted as rigorously as possible?

AHHH Wikipedia RUN! Wikipedia should only be used for a launch pad to other credible websites... Unless you have checked the sources I would be skeptical as to the legitimacy of the research. (I read your post and obviously there's a journal article there) Anyway, that's my two cents on...
