(PhysOrg.com) -- As every young science student knows, moving objects have kinetic energy. But just how much energy does something need to move? In a new study, a pair of physicists has shown that ...

From diamonds to snowflakes to salt, crystals are common in nature. The arrangement of their atoms in orderly, repeating patterns extending in all three spatial dimensions doesn't just make them nice ...

Inventors have been coming up with designs for perpetual motion machines for centuries even though they’re completely impossible. Perpetual motion machines are impossible, right? They violate the laws ...

We are at a critical time and supporting science journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen scientific ...

(via PBS Space Time) Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the perpetual motion machine. No working perpetual motion ...

(via Royal Institution) Perpetual motion machines are tantalising. Videos of contraptions claiming to have achieved the impossible goal of endless free motion rack up millions of views on YouTube. But ...

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 ...
