Done for the week!

I am done with homeworks for this week! It might not seem like much, since tomorrow is Friday. Still, some of the past weeks I have spent most of Friday evening's working on the Classical Mechanics problem sets that are done on well, Fridays.

On Sunday I worked on the Classical Electrodynamics homework assignments. We are not studying electromagnetic waves. Most of the problems were about calculating transmission and reflected coefficients with two interfaces of materials. These problems have an awful amount of algebra with the boundary conditions. It was sad that I was not able to worked out all the cases for the last problem. Oh well! I am doing pretty bad on this course, so I have a feeling I am going to have to repeat it next fall, which is a bit annoying considering that I have to catch up on some fancy Theories...

After I handed the E&M problem set on Monday, it was time for Quantum Mechanics. Three problems, mostly on electromagnetic terms in the wavefunction (gauge invariance). The first one was about a magnetic monopole. The second problem was about the spin precession of an electron in a uniform magnetic field and the last problem was to calculate a commutator for the x- and y- components of the mechanical momentum. This problem set took a while since I was just out of it thinking of crazy things that were not helping. I handed the quantum problems today.

Finally Classical Mechanics! This time it was on fluid dynamics. Two problems, one to determine the free shape of a fluid rotating in a cylindrical vessel. The other was to find the velocity profile for a sphere submerge in a flowing fluid with constant asymptotic behavior. Fun, fun!

Two homeworks left for this fall 2006 semester. The E&M is looking a bit long, but doable. Mechanics is going to be just redoing old problems, but using the Hamiltonian method. I think it is going to be alright. Quantum Mechanics final on Tuesday! I am leaving tomorrow afternoon to Massachusetts for some quality time.

Snow is around the corner!
