That’s right, today is Nicola Tesla’s 153rd Birthday. The man who invented AC power, the electric motor, the florescent light (years before Edison came up with the incandescent light bulb), the field of RC and the first Remote Control vehicle (a boat), the audio speaker, and Radio (no, it wasn’t Marconi; his patents were invalidated in 1943). He also invented the Tesla Coil and Broadcast Power (never deployed because no one could figure out how to put a meter on it for billing purposes), and there was a rumor that he built a book-sized vibrator that could topple buildings and caused an earthquake. He contributed to a lot of other fields, including Robotics and Radar, he has a ton of published articles and patents, and my favorite bit: he was the guy for whom the phrase Mad Scientist was coined! Happy Birthday, Nicky!
