Analog Computing and the Computer of the Tides with Charles Petzold

Charles Petzold taught many of us to code Windows, but now he's turning his attention to a new book he's been working on for over a decade! This week Scott talks to Charles about Analog Computing and the Computer of the Tides. He's exploring an extended history of an early analog computer invented by Scottish scientist William Thomson (Lord Kelvin), and its role in the 19th century Darwin Wars.
