Lecture 5 Motion of a charged particle in a magnetic field
What is effect of a static electromagnetic field on a charged particle? Classically, in electric and magnetic field, particles experience a Lorentz force: F = q (E + v × B) q denotes charge (notation: q = −e for electron). Velocity-dependent force qv × B very different from that derived from scalar potential, and programme for ...

Operator methods in quantum mechanics
www.tcm.phy.cam.ac.ukthe quantum mechanics of bound and unbound particles, some properties can not be represented through a wave-like description. For example, the electron spin degree of freedom does not translate to the action of a gradient operator. It is therefore useful to reformulate quantum mechanics in a framework that involves only operators.

Cathode rays are called cathode rays because they are emitted by the negative electrode, or cathode, in a vacuum tube. In 1897, an English physicist Sir J.J. Thomson showed that the rays were made up of a stream of negatively charged particles.
