Scientists have found that it’s possible to generate electric power from Earth’s rotation through its own magnetic field using a magnetic tube resting stationary on the planet’s surface. But before ...

The film explores the concept of electricity, demonstrating how it can be generated through simple experiments such as rubbing different materials together. It explains the basics of electric currents ...

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...

Bits of material levitating against gravity, a stream of water deflected by invisible means, sparks of light appearing out of thin air; with observations like those, it’s a wonder that the early ...
