Colóquio da Pós-Graduação - Prof. Dr. Pedro Vieira (IFT/Unesp)
Título: Possível e Impossível
In the 50's physicists were trying to figure out nature by constraining the fundamental rules of nature as dictated by quantum mechanics, relativity and analyticity. Today we know that was naive. We can not constraint theories uniquely by pure thought for many reasons. One reason is that there is no single theory! There is a big space of possible theories. By shifting perspectives and aiming at carving out this space - instead of figuring out individual theories - beautiful progress has been made in the recent year reviving the 50's S-matrix Bootstrap program. I will review some fun news results in this direction.
