Narrowing my son's grad school search

My son is a junior physics/math major at a small midwestern state university. He needs to start looking at graduate programs. He would prefer to stay in research or academia. How can I help him start this process? (B.S. for me) Location is not an issue. It's more a question of what programs offer the best opportunities and fields of study. How can we find out that kind of information? How can I help him start with a reasonable number of candidates?

extrapolating temp/energy use difference from small boxes to my condo

Physics geeks! Help me save energy! How do I estimate how much less energy will be used by light siding vs gray siding, based on an experiment with small boxes? I made some identical boxes, put them in the sun, measured temperatures, and am trying to figure out how to scale up. The net has info about different roof colors, but not siding colors.

I was banned from collegeconfidential just for asking for some help?

Summer vacations are coming up and I am going to use some of my free time to learn physics and math, subjects that I love. In order to do that i asked collegeconfidential.com if anyone had "exclusive study materials" from their university which they could share. I mentioned that I would like to have acess to tests and exams from other universities and I could give some good materials collected by my colleagues of the physics and math course in exchange.

What was this geometric creature builder website?

Several years ago, I saw a website with a fun little flash or javascript applet thingy where you could build little tensegrity structure creatures, then have oscillating movements applied to the pieces, so that the structures would seem to "walk". I don't remember what it was called! From memory, one of the simpler structures looked sort of like this. What was it? Is it still online? [more inside]

Should I pursue my interest and study college physics more?

Should I pursue my interest and study college physics more? Specifically, should I take a year-long calculus-based program, until I get comfortable that I'm on top of it-- and can really judge my level of interest and aptitude fairly? Considering I'm a Junior English major. Also considering that it's been 15 years since HS algebra and I've never been good at math. But I want to be. [more inside]

Linguistic study of math/physics equation "language"

I was thinking the other day about "all Greek to me!" as I was reading a physics book w/equations (using the Greek symbols) And equations are a sort of language, of course. So I wondered if there's some sort of linguist who's ever looked at the grammar or syntax of math/physics equations and tried to derive, whatever the hell it is linguists derive! Does this sound like something anyone has heard of? If so, have any links?

Can I learn quantum mechanics?

I'm reading Quantum: a Guide for the Perplexed and I'm enjoying the graphics, history and simplification of the math and science used to explain quantum mechanics. But I'm reasonably well versed in math and science - I took a year of college physics, linear algebra, and diff eq about ten years ago. Is there any chance of me learning to understand the equations and papers of Planck and Einstein that are the basis of QM? Are there any good books that could help walk someone like me through this stuff? Or am I stuck as a layperson unless I earn a degree in math or physics?

The relation between temperature, ballistics and sonic booms

Need to get a double-check on some extracurricular science number crunching. A friend and I were wondering about how much effect cold temperatures would have on the speed of sound, and I had the idea to see if some handgun calibers could go from subsonic to supersonic at reasonably cold temperatures. After some extensive calculations, I think I have a pretty good set of numbers, but I want to make sure I'm not wrong. [more inside]

Math for pre-schoolers

My cousin's four year old son is obsessed with things like quarks and infinity. He insists to his mother that infinity is the last number. She isn't so sure, and wants to know more about things like strangeness. I don't want to determine this kid's future, but it seems fun to feed his curiosity. And since my wife's babysitter was Murray Gell-Mann, the responsibility has fallen partially on my shoulders to help answer his questions. What kinds of information can you recommend that I give to his mother so that she, an attorney and not a mathematician, and her son can learn more about this information. In particular, what kinds of books, games, and projects would introduce him to other neat ideas in mathematics and physics?

death comes in threes, science works in twos...?

When reading a book about Newton V's Leibniz recently, it occurred to me that great advances in Science often seem to occur in tandem, ie two unrelated persons or groups often arrive at a breakthrough at roughly the same time. Is this true? Can anyone think of some other examples? Can anyone explain why this may be the case?
