[ UPDATED November 2014 ]
I remember the first time I learned about the finality of entropy.
I had a job in the military maintaining an education facility. It was a place where you could come in and borrow military training books, regular books, etc. And there were tons of videos as well.
I found a video set about physics put out by Caltech.
It was utterly brilliant. I watched the whole thing multiple times, and I think this is where I learned about entropy.
It’s like nature’s trump card. There’s no coming back from it.
I think if we are to aspire to a final goal, above the trivial ones of our animal variety, it’d be to find a way to escape the heat death.
