A 500-Year-Old ‘Paradox’ By Leonardo Da Vinci Has Finally Been Solved

  • More than 500 years ago, Leonardo da Vinci was watching air bubbles float up through water—as you do when you’re a Renaissance-era polymath—when he noticed that some bubbles inexplicably started spiraling or zigzagging instead of making a straight ascent to the surface.
  • For centuries, nobody has offered a satisfying explanation for this weird periodic deviation in the motion of some bubbles through water, which has been called “Leonardo’s paradox.”
