Here is a listing of my mathematica notebooks. The most recent of any of these notebooks can all be obtained from my github Mathematica repository.

The Wolfram CDF player can also be used to view a number of these notebooks after download.

Some step and rect function plots.

- Oct 31, 2011 phy456/plot_question.nb
Another stackoverflow mathematica question. Why no output in my plot. Learned about Mathematica local and global variables as a result.

- Oct 31, 2011 phy456/problem_set_7_verify_rotation_matrix_orthonormal.nb
A sanity check on a rotation matrix calculated as part of a problem set.

- Dec 17, 2011 phy456/qmTwoExamReflection.cdf
Exam problem 2a. Calculate the matrix of a Perturbation Hamiltonian $-\boldsymbol{\mu}_d \cdot \mathbf{E}$ with respect to the $n=2$ hydrogen atom wave functions.

- March 28, 2013 phy456/24.4.3.newAttempt.nb
A new attempt at Desai 24.4.3 from scratch. This one has an error, as did the original. The original is now fixed.
