TED Talk: How to take a picture of a black hole | Katie Bouman

A talk on how the process would work presented a couple years ago. Interesting how closely the actual image matches the reconstruction before they did it.

At the heart of the Milky Way, there’s a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close — even light. We can’t see it, but its event horizon casts a shadow, and an image of that shadow could help answer some important questions about the universe. Scientists used to think that making such an image would require a telescope the size of Earth — until Katie Bouman and a team of astronomers came up with a clever alternative. Bouman explains how we can take a picture of the ultimate dark using the Event Horizon Telescope.

TED Talk: Leonard Susskind: My friend Richard Feynman

What would be in your sandwich?

Richard Feynman wrote a couple of my favorite books: The Pleasure of Finding Things Out and The Meaning of It All: Thoughts of a Citizen-Scientist. It was reassuring to find someone who held similar views on the world.

Susskind’s The Black Hole War is on my to-read list. Guess I should bump it up higher in the list.
