« What is dynamics in quantum gravity? » 
P. Malkiewicz 
I will discuss the reduced phase space quantization of canonical relativity. I will show how the choice of the so called internal clock determines the properties of the resultant quantum theory. It turns out that by changing clock the quantum dynamics of a given system may be altered almost unboundedly. Nevertheless, there exist important statements about the dynamics of a given quantum system that are independent of the employed clock. For illustration I will use simple cosmological models. I will also show how the presented result can be reconciled with quantum mechanics based on the deterministic evolution of a wavefunction.
