Richard Feynman proposed a way of obtaining energy from this phenomenon using a namesake "ratchet.
Richard Feynman proposed a way of obtaining energy from this phenomenon using a namesake "ratchet." One of the papers from Einstein's "Annus Mirabilis" calculated displacement due to this phenomenon, which is caused by an imbalance in the force on a particle due to molecular collisions. It was first observed by its namesake Scottish botanist in a mixture of pollen and water. For 10 points, give this term for the random motion of suspended particles in a fluid.
