Trickle-Down Theory

German and Swiss physicists have turned their physics knowledge to the foreign exchange markets. The movement of currency through the world economy has long baffled economists, who have tried to apply a number of different mathematical models to predict how they will work. But the physicists have found a “surprisingly good fit” when they used an existing model from the physics world to predict the flow of currency: one that predicts the flow of turbulent water. “The qualitative picture of turbulence that has developed ...will help our understanding of the apparently remote field of financial markets,” they wrote in the journal Nature.
