“When I meet God, I am going to ask him two questions: why relativity? And why turbulence? I really believe he will have an answer for the first.”
Those were the words 20th century German theoretical physicist Werner Heisenberg used to describe one of the most complex scientific principles in history: turbulence. It’s so complicated, in fact, that scientists still don’t completely understand how it works; as Nature reported in 2006, it’s still unsolved, and “some are said to have considered the problem harder than quantum mechanics.”
