ABOUT THE FQXi PODCAST

The FQXi podcast brings you the latest ideas in foundational physics and cosmology—and includes interviews with our members and other leading scientists. It's hosted by Zeeya Merali and Brendan Foster. You can contact us at podcast@fqxi.org, and follow us on twitter: @FQXi. The podcast is produced by Zeeya, and music is provided by Baltimore-based Diefenbaker.

**Quantifying Occam**

Is the simplest answer always the best? Connecting Medieval monks to computational complexity, using the branch of mathematics known as category theory.

**Heart of Darkness**

An intrepid physicist attempts to climb into the core of black hole.

**Why Quantum?**

Entropy could explain why nature chose to play by quantum rules.

**Reality's NeverEnding Story**

A quantum version of Darwinian natural selection could enable the universe to write itself into being.

**The Quantum Dictionary**

Mark Van Raamsdonk is re-writing how we define the shape of our universe. Can such translations help to unite quantum theory and gravity?
