I just noticed as I was writing my research paper on perpetual motion, as I was going over the laws of thermodynamics, I realized that it is like the plot of I Robot. In I robot, the 3 Laws the robots must follow is like the laws of thermodynamics. The robot/computer program security system thingy known as Vicky or something like that, is the person who comes up with the perpetual motion device. She delivers her logic explaining to the robots that perpetual motion is real or that they should hurt them to protect them. she uses her logic that cant really be argued. Will Smith is like the Physicist who trys to prove the robots or evil or perpetual motion is false. in the end he destroys the creator of the evil logic, but thats too extreme for this. a physicist wouldn't shoot an inventor. but it can be compared to him debunking the theory and stuff. So, what did we learn today class? There are subliminal physics lessons in your latest SciFi films.
