From 00:00 to 11:59 First he speaks about deterministic. He defined it in the following way: wherever you happen to be, you know exactly where to go next, so it's deterministic into the future. I.e. wherever you start, you know where you will be arbitrarily into the future and also you know where you were before.
From 12:00 what kind of laws of physics do we not allow? Classical Mechanics forbids a system that has a deterministic from one direction and not from the other (e.g. possible from past to current but not from current to future). How do know if classical mechanics is allowable deterministic? Just check if each node has degree of income equal degree of outgoing.
From 23:00 How much do you need of states to say what happen next? This brings us to continuous physics. Systems in classical mechanics are deterministic and reversible. Besides, systems could be infinite of chains of states or cycles. Conservation Law is just memory where we started. Information Conservation is the one that you never lose memory where you started. Information Conservation is perhaps the most fundamental law of basic classical physics.
32:42 1st order equation means it has only quantities of 1st deterministic with respect to time.
41:35 give a good example of Head and Tail.
