Christian Huygens (1629–1695), the greatest clockmaker in history, suggested that an international unit of length could be defined as the length of a simple pendulum having a period of exactly 1 s. How much shorter would our length unit be if his suggestion had been followed? Calculate as exactly as possible, supposing that Huygens lived in your city. And then could you show your design blueprint? What if Huygens had been born on another planet? What would the value for g have to be on that planet such that the meter based on Huygens’s pendulum would have the same value as our meter?
