“Semiprime rings, cont’d”
Continuing our discussion of prime and semiprimeness: a ring R is semiprime if it has no nilpotent ideals. We’ll relate this to prime rings, and show that if R is semiprime artinian then it satisfies the Artin–Wedderburn theorem.

“Randomness Continued”
Last time we introduced Martin-Lof randomness, and saw that most reals have this prop- erty.
This week, we will give an example of one specific Martin-Lof random real, discuss some of the properties which such reals satisfy, and give another characterization of them.

“Packing measure and a theorem of Besicovitch”
Packing measures, as well as Hausdorff measures, are used to provide fine information on the size of fractal sets. For many random sets, especially related to Brownian motion, packing measures (rather than Hausdorff measures) provide the right concept to measure the size of the set.

“Dirac Field”
This week we will discuss fermions. Starting from representations of the Lorentz group and traversing carefully through Clifford algebras and spinors, we will finally arrive at the quantization of the Dirac field.
