You've probably seen videos showing characters walking through walls like ghosts. Upon closer inspection, atoms consist of a ...

This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

Within an atom, electrostatic force is what keeps electrons orbiting the nucleus. The ones farthest away from the nucleus can sometimes escape, leaving the atom positively charged (more protons ...

Electrostatic Force Microscopy (EFM): A scanning probe technique that measures long-range electrostatic interactions between a conductive tip and a sample to deduce local dielectric properties.
