    (4/4) Operation: The details of setting up the Harmonic Analyzer

    (4/4) Operation: The details of setting up the Harmonic Analyzer

    This series on Albert Michelson’s Harmonic Analyzer celebrates a nineteenth century mechanical computer that performed Fourier analysis by using gears, springs and levers to calculate with sines and cosines—an astonishing feat in an age before electronic computers. This video (the fourth of four) shows how to operate the machine. Check out the series companion book and learn how to get a free PDF of the entire book at http://www.engineerguy.com/fourier.

Accurate, funny, and engaging

My kids love these videos, and I love having my kids watch them. They don't just include accurate information on how things work, but they do so in an engaging way.

Communicates well across many experience levels

I really enjoy this series. He has the ability to teach non-technical people. For technical people, he's able to supplement our understanding of engineering concepts.

I've recommended this podcast to many of my fellow engineers.
