The Bohr Magneton is a physical constant which is used to express the dipole moment of electrons. It corresponds to the angular momentum of an electron in the lowest orbital. The Bohr Magneton relates the splitting of atomic energy levels to the strength of an applied magnetic field. The Zeeman effect offers us an easy way to observe this splitting. In this lab report, I discuss a how to observe the Zeeman effect, and how it can be used to compute an accurate value for the Bohr Magneton.

A random walk (sometimes called 'the drunkard's walk' describes the motion of a particle that undergoes a series of random steps. But what happens if that particle is a quantum particle? This article presents a few interesting ways of visualising this motion, using Python and matplotlib.

X-ray diffraction is an experimental technique that can be used to look at structures made of repeating lattices - anything from crystalline solids to crystallized biological molecules. In this lab report, I describe an experiment to determine the lattice parameters and Bravais lattice using 1-D X-ray diffraction patterns.
