But does it really matter if itโs possible for us to make such predictions? If a hypothetical omniscient observer (i.e. Laplaceโs demon) could predict all your decisions, then that already shows that theyโre deterministic. Us not being able to actually do the determination wouldnโt change the fact that there is a definitive state of the universe for any point in time.
Simon Tathamโs Puzzle Collection. Just a bunch of cool puzzles for wasting time. No ads or bells and whistles.
You can download them or just play in the browser. Someone also made the collection into an Android app, which I usually use.
