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 ...

Motion of a charged particle in magnetic field is described by the change in the direction of motion. It is described as magnetic field which is capable of only changing direction of motion. Motion of ...

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 ...

Scientists have uncovered a new way to control magnets using flashes of light lasting less than a trillionth of a second. The approach triggers unusually large magnetic motion without direct contact ...

Magnetic Resonance Imaging (MRI) is an indispensable tool in modern medicine; however, its sensitivity to patient movement can significantly impair image quality. Motion correction techniques have ...

In 1967, half a century after the discovery of superconductive metal, Popular Science covered the emerging field and its potential futures. By Bill Gourgey Published May 2, 2022 11:00 AM EDT Get the ...
