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 holy grail of scientific inquiry in the Middle Ages was the perpetual motion machine. Was it possible to create a mechanical apparatus that could run—forever—without any external power source? One ...

While this is authentic footage of a genuine product, the "perpetual" marble machine does not operate infinitely without an additional energy source. Rather, it uses batteries and a magnet to create ...
