We begin our detour with a picture of handwritten notes. At this point in time it will not be entirely necessary to go deeply into Quantum Field Theory.
We only need to be aware that a crucial step in quantizing a field theory is to make spacetime discrete by dividing it into lattices. Perhaps I should be more careful here. Gerard t’Hooft is especially interested, page 15 “The Conceptual Basis of Quantum Field Theory”, in the discretization of time. He writes that; T⁄ Ν = δt.
