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 ...

Conservation of energy isn’t just a good idea: It is the law. In particular, it is the first law of thermodynamics. But, apparently, a lot of people don’t really get that because history is replete ...

This experiment puts a supposed perpetual motion device to the test. We break down how it works, what physics says should happen, and whether the motion can actually last without an external energy ...

Perpetual motion devices are either a gag, a scam, or as in the case of this particular toy that [Big Clive] bought on AliExpress, a rather fascinating demonstration of a contact-free inductive sensor ...

A wheel weighted with swinging mallets. A cylinder rotating in a sealed, water-filled container. A siphon that transfers liquid back and forth in a seemingly endless loop. These may sound like the ...

A group of students at Ransom Everglades High School in Coconut Grove will see their science experiment launched on a Blue Origins rocket, as part of a program sponsored by NASA. The milestone is ...

At the turn of the 20th century, the quest for a perpetual motion machine took hold of public imagination. A number of Hoosiers were among those captivated by the idea of creating a perpetual motion ...

Testing the idea of a perpetual motion loop with a large-scale setup and explores the science behind it. Trump ends fiery address to the nation with a 'victory lap' Wenxiu Lived A Broken Fairy Tale ...
