The Mechanical Universe

Alternating Currents. Electromagnetic induction makes it easy and natural to generate alternating current. Alternating current circuits obey a differential equation identical to the harmonic oscillator resonance equation. Use of transformers makes it practical to distribute AC over long distances. Nikola Tesla understood all this, Thomas Edison chose not to, and thereby hangs a shocking tale of incandescent inspiration, galvanic perspiration and patently offensive skullduggery!
