Everyone loves perpetual motion machines. They are a representation of the highest level of creativity in finding loopholes in the laws of physics. Let's take a look at this one. What is a perpetual ...

Perhaps the most persistent nonsense in physics: the perpetual motion machine. Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the ...

The search for a perpetual motion machine has been the chupacabra of physics for centuries. Multiple designs have been made, tested and, ultimately, found lacking. Perpetual motion machines are ...
