Can anyone please recommend me a good book on undergraduate level solid state physics preferably with plenty of examples for self study? Thanks.

Hi, The other options clashing with General Relativity are JAVA and Physics of the Earth. If I don't choose GR, just wondering which of the two modules would be more worth it in the long term as I'm still undecided in what I want to do after I graduate.

Hi, I am in my 3rd year and have General Relativity as one of my options. I'm kind of feeling the peer pressure of selecting General Relativity, but putting all the hype aside, is it really necessary to learn General Relativity for an Experimental Physicist? I have to say, maths isn't really...

So a particle of mass M is moving in one dimension given by: x(t) = (alpha)t^2 + (beta)t + (gamma) where alpha, beta, gamma are non zero constants. What are the dimensions of the alpha, beta, gamma? Either the answer is staring right at my face or my physics is rusty :/
