"Advanced understanding of the laws of thermodynamics. Allows you to deliberately overheat a ship's modules in order to push them beyond their intended limit. Also gives you the ability to frown in annoyance whenever you hear someone mention a perpetual motion unit."
— Part of the description of the Thermodynamics skill, EVE Online
"Kid, a perpetual motion machine has one job: to not stop!"
— College Board Member, Gravity Falls
"These are divergent technology power sources that operate without requiring fuel, in violation of thermodynamic laws such as conservation of energy. Typical devices are mechanical or electromechanical in nature and involve a complex array of self-moving wheels, rolling balls, spinning disks, magnetic fields, or pressurized gases and liquid, all somehow managing to generate more power than they consume in operation.
"And this 'perpetual motion' machine she made today is a joke — it just keeps going faster and faster."note
