Silly sprinklers spin,
Solving Feynman's age-old riddle—
Water's own force flows.
Solving Feynman's age-old riddle—
Water's own force flows.
A team of mathematicians used whimsical "silly sprinklers" to solve a physics mystery that has puzzled scientists for decades. Their experiments showed that the rotation of both normal and reverse sprinklers is driven by the momentum of flowing water, not by the outside water flow…
