I love maths and physics but I not the official teaching system which is far from explaining these things as clearly and interestingly as they deserve. So I undertook to write about this by my site settheory.net . I live in France, sometimes travel to eastern Europe, and would occasionally offer (for free) some teaching of introduction to linear algebra (tensors) and theoretical physics (relativity and quantum physics) if I happened to find a public. I also have a project of decentralized online social network (based on web servers like the web is now but no central owner in the way every particular "network" is now) : trust-forum.net
