Don't forget to double up (at least!) on the books! After the unveiling, everyone will say "OK, I think I'll start at the beginning, where's the *intro physics text*? Hmm, it's gone..."

I'm just going into my fourth year of a Physics degree and I'm currently doing undergrad research. Take it from me, it''s incredibly valuable. Even if it's nothing to with your desired PhD, there is so much else to learn! You get so many valuable insights into life AS a scientist. Your work will...

Hi, I've always tken for granted that KE=(mv^2)/2, but never seen the derivation! I think it probably comes from U= - inegral of the force, but I can't see which force to use. Any help anyone? Maybe dimensional analysis was used? Thanks!

Sorry everyone! I was mistaken in what the integral should actually be: it should be the integral of rexp(-ar^2). I should be using cylindrical co-ords, not spherical. Thanks for the help though!

Hi! Can someone help me with this integral? I can't seem to get my head around it! Integrate r^2.exp(-ar^2) imperfectly. Thanks!
