Hi. I was wondering if you could help me out a bit here. I have a choice to take either a module on stochastic dynamics in statistical mechanics or quantum computing for my masters. Both seem really interesting so it’s a close tie between which one has more current/future applications. The...

The thing is, your tangential velocity is continuously pushing you against the side of the wall. So the normal force is what is preventing you from going through the wall. However, unlike gravity, the normal force doesn't give you kinetic energy, it exists only when you are against the wall and...

Homework Statement If there are a large number of ions oscillating in a straight line, we can pick the nth one oscillating about its equilibrium a*n. The potential of the entire lattice is then U = 0.5*K[u(an)-u([n+1]a)]^2 - summed over all n. How do I use Force = -dU/du(an) to derive that...
