Title:   Does time exist?
Abstract:
Loop Quantum Gravity represents an example of a theory with no time defined. Using elementary considerations in classical mechanics, we introduce a notion of "intuitive" (Newtonian) time and discuss if and when it can be defined in a particular theory. We shall analyze in more detail an example of timeless double pendulum. The goal of the seminar is to point to the problem of time in LQG using this elementary example.
