Fait-divers by John Horton Conway

"That’s a curious thing about the nature of mathematical existence. This rule hasn’t physically existed in any sense in the world before a month ago, before I invented it, but it sort of intellectually existed forever. There is this abstract world which in some strange sense has existed throughout eternity. Imagine an uninhabited planet, full of interesting things. You land on it, and it existed for a million years, but no people have ever been there, no sentient beings. There are such places, I’m sure. Go to some remote star and there will be something. But you don’t have to go there. You can sit in this very chair and find something that has existed throughout all of eternity and be the first person to explore it." (John Horton Conway)

Fait-divers on black holes

"as a black hole radiates Hawking radiation, it slowly evaporates until it eventually vanishes. So what happens to all the information encoded on its horizon? Does it disappear, which would violate quantum mechanics? Or is it preserved, as quantum mechanics would predict? One theory is that the Hawking radiation contains all of that information. When the black hole evaporates and disappears, it has already preserved the information of everything that fell into it, radiating it out into the universe."

Fait-divers on storytelling

Stories are our user manuals for life.

Fait-divers by Susan Sontag

"Books are not only the arbitrary sum of our dreams, and our memory. They also give us the model of self-transcendence. Some people think of reading only as a kind of escape: an escape from the “real” everyday world to an imaginary world, the world of books. Books are much more. They are a way of being fully human." (Susan Sontag)
