(2/4) Synthesis: A machine that uses gears, springs and levers to add sines and cosines

Update: 2014-11-26

Description

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 second of four) shows how to use the machine to do Fourier synthesis.
