Oct 31, 2010 Believed to be typos in Desai's QM Text

Believed typos, some confirmed, in Desai's QM book.

Oct 30, 2010 Multivector commutators and Lorentz boosts.

Use of commutator and anticommutator to find components of a multivector that are effected by a Lorentz boost. Utilize this to boost the electrodynamic field bivector, and show how a small velocity introduction perpendicular to the a electrostatics field results in a specific magnetic field. ie. consider the magnetic field seen by the electron as it orbits a proton.

Momentum and Energy transformation to derive Lorentz force law from a free particle Hamiltonian.

July 27, 2010 Rotations using matrix exponentials

Calculating the exponential form for a unitary operator. A unitary operator can be expressed as the exponential of a Hermitian operator. Show how this can be calculated for the matrix representation of an operator. Explicitly calculate this matrix for a plane rotionation yields one of the Pauli spin matrices. While not unitary, the same procedure can be used to calculate such a rotation like angle for a Lorentz boost, and we also find that the result can be expressed in terms of one of the Pauli spin matrices.

A linear appromation to a hoop and spring problem.

May 31, 2010 Infinite square well wavefunction.

A QM problem from Liboff chapter 4.

May 30, 2010 On commutation of exponentials

Show that commutation of exponentials occurs if exponentiated terms also commute.

May 29, 2010 Fourier transformation of the Pauli QED wave equation (Take I).

Unsuccessful attempt to find a solution to the Pauli QM Hamiltonian using Fourier transforms. Also try to figure out the notation from the Feynman book where I saw this.

May 28, 2010 Errata for Feynman's Quantum Electrodynamics (Addison-Wesley)?

My collection of errata notes for some Feynman lecture notes on QED compiled by a student.

May 15, 2010 Center of mass of a toroidal segment.

Calculate the volume element for a toroidal segment, and then the center of mass. This is a nice application of bivector rotation exponentials.

Mar 7, 2010 Newton's method for intersection of curves in a plane.

Refresh my memory on Newton's method. Then take the same idea and apply it to finding the intersection of two arbitrary curves in a plane. This provides a nice example for the use of the wedge product in linear system solutions. Curiously, the more general result for the iteration of an intersection estimate is tidier and prettier than that of a curve with a line.

Mar 3, 2010 Notes on Goldstein's Routh's procedure.

Puzzle through Routh's procedure as outlined in Goldstein.

Feb 19, 2010 1D forced harmonic oscillator. Quick solution of non-homogeneous problem.
