Zeno's Paradox & The Quantum Zeno Effect
Season 7
Episode 12
A moving arrow is at rest.” Zeno, a Greek philosopher famous for his metaphysical trolling, devised a paradox whose conclusion is just this. If we’re talking about a quantum arrow, there may be a way to freeze its motion simply by looking at it, through the aptly named quantum Zeno effect. The Quantum Zeno effect predicts that certain quantum events can be frozen through this act of observation.
