I'm starting my maths bachelor in september and I'm trying to find out which lectures get recorded. I live far from Lausanne and the commute is long, so I need to plan ahead.

- MATH-100(a) Analyse avancée I - Boumal

- MATH-110(a) Algèbre linéaire avancée I - Kressner

- MATH-113 Algèbre I - Wyss

- PHYS-101(f) Mécanique - Bréchet

- CS-119(l) ICC - Doeraene

Does anyone know whether these teachers record their lectures, and if so where the videos end up (Mediaspace, Moodle, ...)?

Thanks!

In pure set theory, every element of a set is also a set. While I know this has useful applications for constructing mathematical objects, like building other sets. I'm curious about the negative consequences of abandoning it. What paradoxes or mathematical contradictions arise if we allow elements to exist that aren't sets?
