About First Principles Daily

From the publisher's feed

A daily narrative podcast that reasons about the world from first principles — the 'magic wand number' and the 'Idiot Index'. Episodes alternate between a concrete example of first-principles thinking in action (historical and modern — Ford, Bessemer, the shipping container, solar, batteries, and sometimes Musk's teams) and a deep exposé on an industry ripe for the same treatment.
