Who was Ma Jun?

Ma Jun, style name Deheng, was a Chinese mechanical engineer and government official during the Three Kingdoms era of China. His most notable invention was that of the South Pointing Chariot, a directional compass vehicle which actually had no magnetic function, but was operated by use of differential gears. It is because of this revolutionary device that Ma Jun is known as one of the most brilliant mechanical engineers and inventors of his day. The device was re-invented by many after Ma Jun, including the astronomer and mathematician Zu Chongzhi. In the later medieval dynastic periods, Ma Jun's South Pointing Chariot was combined in a single device with the distance-measuring odometer.
