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.

**Quantum in Context**

An untapped resource could provide the magic needed for quantum computation—and perhaps even open the door to time travel.

**Spot the Difference to Reveal Exotic Particles**

Questioning the symmetrization postulate of quantum mechanics and the notion that electrons are indistinguishable could reveal whether hypothetical new particles exist.

**Life's Quantum Crystal Ball**

Does the ability to predict the future—perhaps with quantum help—define the fundamental difference between living and inanimate matter?

**The Quantum Truth Seeker**

Watching particles fly through an interferometer might help to unveil higher-order weirdness behind quantum theory.

**Quantifying Occam**

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

Sean Carroll Fluctuates on Floating Consciousnesses

Cosmologist Sean Carroll questions conventional wisdom on quantum fluctuations, whether we might be disembodied "Boltzmann Brains" floating through space & eternal inflation leading to a multiverse, in his talk at the 4th FQXi conference.
