How Scientists Finally Solved Feynman’s ‘Reverse Sprinkler’ Problem
The Feynman sprinkler problem—a long-standing physics puzzle involving a submerged sprinkler that sucks in water rather than spraying it—has been solved by researchers led by Leif Ristroph at New York University. According to a study published in Proceedings of the National Academy of Sciences, the device rotates in the opposite direction of a standard sprinkler … Read more
