$AM’s review published on Letterboxd:
“It is obvious to everybody that the phenomena of the world are evidently irreversible. I mean things happen that do not happen the other way. [...]
The demonstration of this in lectures is usually made by having a section of moving picture in which you take a number of phenomena, and run the film backwards, and then wait for all the laughter. The laughter just means this would not happen in the real world. But actually that is a rather weak way to put something which is as obvious and deep as the difference between the past and the future; because even without an experiment our very experiences inside are completely different for past and future. We remember the past, we do not remember the future. We have a different kind of awareness about what might happen than we have of what probably has happened. The past and the future look completely different psychologically. [...]
Now if the world of nature is made of atoms, and we too are made of atoms and obey physical laws, the most obvious interpretation of this evident distinction between past and future, and this irreversibility of all phenomena, would be that some laws, some of the motion laws of the atoms, are going one way — that the atom laws are not such that they can go either way. There should be somewhere in the works some kind of a principle that uxles only make wuxles and never vice versa, and so the world is turning from uxley character to wuxley character all the time — and this one-way business of the interactions of things should be the thing that makes the whole phenomena of the world seem to go one way.
But we have not found this yet. That is, in all the laws of physics that we have found so far there does not seem to be any distinction between the past and the future.
The moving picture should work the same going both ways."
-Richard Feynman, “The Character of Physical Law”
so. fucking. hard.
