I see. Let me clarify. I find the methods used to solve problems in pure theoretical physics really cool and interesting, logically simple, and fun to do. However, the conclusions that they draw (scattering amplitudes of processes, critical exponents of field theories, etc.) I find utterly...
I'm currently a graduate student doing theoretical physics at a tier 1 school. I'm trying to decide between these two.
1) stay in pure physics
PROS:
- since I've already taken field theory, I can start doing research quickly
- will probably learn some useful simulation skills (I'm...
Homework Statement
A system consists of N very weakly interacting particles at temperature T sufficiently high so that classical stat mech is applicable. Each particle has mass M and is free to perform one dimensional oscillations about its equilibrium position. Calculate the heat capacity...

This is Reif, Fundamentals of Statistical Mechanics, problem 5.4
A cylindrical container 80 cm long is separated into two compartments by a thin piston, originally clamped in position 30 cm from the left end. The left compartment is filled with 1 mole of helium gas at a...
if you look at the last post in the thread you gave me, I already got that result. It's just that the R_max I get does not match the R max that's given in the initial problem.
Homework Statement
A ball is thrown with initial speed V up an inclined plane. The plane is inclined at an angle \phi above the horizontal, and the ball's velocity is at an angle \theta above the plane.
Show that the ball lands a distance R = \frac{ 2V^2 \sin{\theta} \cos{ ( \theta +...

Here's the exact wording for this problem:
Sources A and B emit long-range radio waves of wavelength 400 m, with the phase of the emission from A ahead of that from source B by 90 degrees. The distance Ra from A to detector D is greater than the corresponding distance Rb by 100 m. What is the...
believe me, I'm trying as hard as i can to work out the phase shifts, both due to A having a head start and A traveling a greater path, as having opposite signs, but I just can't do it.
Having a head start and traveling a greater path both make A lead MORE. In fact, the length of path B is a...
Homework Statement
let there be three points: A, B, and D. Light of wavelength 400 m is emitted from the source at A to the destination D, and also from B to D. Line segment AD is 100 m longer than BD. The starting phase of the light at A is pi/2 radians ahead of B. At point D, what is the...
