Actually BenTheMan, I'm probably lower than most undergrads. I don't know Maxwells equations (should an undergrad?), and I have forgotten a lot of...
Thanks for the tips. I checked some of the books out on Amazon. "Quantum Mechanics" by Griffiths seems like th ebest bet. The book by Mahan seemed to...
I've been reading a lot of popular science books on Physics, but am getting a little bit annoyed by the lack of any equations. I would like to know...
Liebniz was a lawyer of some sort. But he was a ploymath involved in all kinds of interests. Augustus De Morgan was a lawyer. Cayley, too, was a...
Thanks for replying DH. True, I don't know relativity or QM, so I'm quite happy to think classically. And what is a balance scale? And what is an...
That would mean atoms don't have mass, which they do. Also, oyu haven't exlpained "substance". I'm not sure that will give me mass (in metric...
I see. But then this "known force" is known how? Now I know you can calculate a force. I'm just pondering what it means to do so. In general my...
This should be a simple problem I think, but I've made it into a troublesome one. Consider two rods standing up and leaning against each other...
Please don't be put off by my title. This is not a wishy washy question. I was recently reading about JH Conway's work. If you don't know who he...
Thanks for the reply. I see what your saying, and I understand the fundamental units (L, M, T...). I understand you can define mass in terms of...
Well the formalist ideas in mathematics do say that numbers and operators are just symbols. Mathematics is just a big game, shuffling letters around...
Good point well made. My mistake.
Wait a minute... Have you mixed up L here? The L in \tau = L/2 W\sin\theta and the L in \tau = LF\cos\theta are different. No? The first is...
Ah thanks, that makes much more sense. I thought what I was doing didn't seem right. So as I lean the book ever wider and the angle gets bigger and...
I looked through this article: http://en.wikipedia.org/wiki/Mass. It didn't answer the title question. Usually it states A body's mass determines......
A book is standing vertically up on a table. I lean another book against it, making an angle of \theta degrees with the vertical, say. Let's say the...
Well, I was considering throwing the balls, not catching them. I think even the act of throwing a ball upwards will break the bridge. Downwards,...
Here is a logic (or lateral thinking) puzzle a friend recently asked me. (I'm going from memory, so anyone who knows this puzzle might know it a...
I'm thinking carefully about what everyone said. Thanks for replying. I also followed the wiki links. Thanks! Just to give you one quote from...
Thanks AlphaNumeric. So KK is studied, but does not help (so far as we know) to unite QT and GR. That is interesting. Just out of interest, is...
Separate names with a comma.
