|
Physics 4Q03 Lecture 18: This lecture continues the previous one on photons in electromagnetism, and provides a sermon about UV and IR divergences and why you can use any regularization you like to…

Physics 4Q03 Lecture 19: This lecture evaluates the Casimir energy for the vacuum fluctuations of a field between two plates on which the field vanishes, showing that it is UV finite. Along the way…

Physics 4Q03 Lecture 27: This lecture describes the logic that determines which fields can be used to represent particles of different spins, and describes the requirement of microcausality and why…
