Fedele Lizzi: Pointless Physics 10/16/19

Abstract: I will describe the role of points in modern physics, and in particular in the attempts to built a theory of quantum gravity. Modern theories will require a quantum spacetime, and in it the usual concept of point, as we have used so far, may lose its meaning. In particular I will discuss noncommutative geometry, a branch born to describe the quantum space of velocity and momenta, and how it could be useful in quantum gravity.
