87 | Karl Friston on Brains, Predictions, and Free Energy

If you tell me that one of the world's leading neuroscientists has developed a theory of how the brain works that also has implications for the origin and nature of life more broadly, and uses concepts of entropy and information in a central way — well, you know I'm going to be all over that. So it's my great pleasure to present this conversation with Karl Friston, who has done exactly that. One of the most highly-cited neuroscientists now living, Friston has proposed that we understand the brain in terms of a free energy principle, according to which our brains are attempting to model the world in such a way as to minimize the amount of surprise we experience. It's a bit more complicate than that, but I think we made great headway in explicating some very profound ideas in a way that should be generally understandable.

Mathematics is often thought of as the pinnacle of crisp precision: the square of the hypotenuse of a right triangle isn't "roughly" the sum of the squares of the other two sides, it's exactly that. B...

It's a well-worn cliché that oceans cover seventy percent of the surface of Earth, but we tend to give them secondary consideration when thinking about the environment. But climate change is wreaking ...

Games are everywhere, but why exactly do we play them? It seems counterintuitive, to artificially invent goals and obstacles just so we can struggle to achieve them. (And in some games, like Twister, ...
