  These are the lecture notes used in the course Understanding Quantum
Chemistry for 1st year master chemistry at the Vrije Universiteit Amsterdam.
The schedule is 2 weeks on HF and 2 weeks on DFT, which provides a quite rough
ride for the the students. The lecture notes also include exercises. I have
started to write them in 2013 and each year I try to find the time to improve
them.
