Ideas and surprises of mathematical physics in simplest examples

quantum theory of fields the origin of infinities and the missed branchpoint to moncommutative geometry

Europe/Moscow
Description
 
The talk would be devoted mostly to physics.
I will discuss the quantum theory of fields  the origin of infinities and the missed branchpoint to moncommutative geometry.
I will also speak on Feynman integral approach, on how strange notion of virtual particle appeared and how it became real in minds of physicists. And on strings as descendants of virtual particles.
