#  Since a given system can never of its own accord go over…

![“Since a given system can never of its own accord go over into another equally probable state but into a more probable one, it is likewise impossible to construct a system of bodies that after traversing various states returns periodically to its original state, that is a perpetual motion machine.” quote by Ludwig Boltzmann](https://sms4smile.com/quotes/i/2ec/ludwig-boltzmann-31218_accord_since-a-given-system-can-never-of-its-ow_2431812.jpg)   [Download](https://sms4smile.com/quotes/i/2ec/ludwig-boltzmann-31218_accord_since-a-given-system-can-never-of-its-ow_2431812.jpg) [Open image](https://sms4smile.com/quotes/i/2ec/ludwig-boltzmann-31218_accord_since-a-given-system-can-never-of-its-ow_2431812.jpg)
