This thought experiment about an apparent perpetual motion machine was popularized by an American physicist who put out a lecture series concerning the nature of the laws of physics that was later recorded and published into a book by which organization?
Brownian ratchet: In the philosophy of thermal and statistical physics, the Brownian ratchet or Feynman-Smoluchowski ratchet is a thought experiment about an apparent perpetual motion machine first analysed in 1912 by Polish physicist Marian Smoluchowski and popularised by American Nobel laureate physicist Richard Feynman in a physics lecture at the California Institute of Technology on May 11, 1962, during his Messenger Lectures series The Character of Physical Law in Cornell University in 1964 and in his text "The Feynman Lectures on Physics" as an illustration of the laws of thermodynamics. The Character of Physical Law: The Character of Physical Law is a series of seven lectures by physicist Richard Feynman concerning the nature of the laws of physics.
