American physicist who shared the 1952 Nobel Prize for Physics, stated the Scallop theorem, in what paper in 1977?
Scallop theorem: The Scallop theorem states that to achieve propulsion at low Reynolds number in Newtonian fluids a swimmer must deform in a way that is not invariant under time-reversal. Scallop theorem:  Edward Mills Purcell stated this theorem in his 1977 paper "Life at Low Reynolds Number" explaining physical principles of aquatic locomotion. Edward Mills Purcell: Edward Mills Purcell (August 30, 1912 – March 7, 1997) was an American physicist who shared the 1952 Nobel Prize for Physics for his independent discovery (published 1946) of nuclear magnetic resonance in liquids and in solids.
