The fletcher’s paradox, proposed by pre-Socratic philosopher Zeno of Elea, states that if you watch an arrow in flight, it looks continuous. But if you segment the flight into points of time, the apparent movement becomes a series of rests. So Zeno asked: Is time continuous, or is it made up of discrete moments? Such age-old questions have important implications for the modern-day field of digital physics, for which the notion of analog (continuous) vs. digital (discrete) plays a critical role when considering a reality made of coded information. Here, members of the distinguished panel weigh in with their unique points of view.
