I'm 6 months into a PhD (admittedly in Chemical Engineering, not physics, but my project has a modelling bent) and, as the title suggests, I've been struggling to find motivation day in and day out.
It's silly: give me an interesting problem in a project not related to my work (say a math...
I'm enjoying Lennard Susskind's lectures on Statistical mechanics. I've briefly studied this material before, but I've learnt a lot about more practical calculations from these lectures: he's used the partition function to derive all sorts of fun expressions, and to analyse the ideal gas and a...

I've been having some difficulty understanding the derivation of the Fundamental Theorem of Thermodynamics, dU=T \ dS-P \ dV.
The derivation, which can be found at Wikipedia (http://en.wikipedia.org/wiki/Fundamental_thermodynamic_relation) first starts with the universal First Law...
