That device, which is in apparent violation of the second (*) law of thermodynamics, is also known as a Feynman-Smoluchowski device.
This adjective describes a construct, developed by HÃ¤nggi and others, which drives directed motion in the presence of thermal noise on the nano-scale. A theoretical device described by this adjective consists of a paddle wheel connected to a gear which can only rotate in one direction because of a pawl. That device, which is in apparent violation of the second (*) law of thermodynamics, is also known as a Feynman-Smoluchowski device. This adjective also describes a process which can be mathematically modeled as a LÃ©vy process. That process was used to calculate Avogadro's constant by Jean Baptiste Perrin, and it is modeled by the Weiner process. For 10 points, name this adjective derived from the name of a Scottish botanist, which names a type of motion studied by Einstein.
