Discover the physics behind TV screens, from phosphors to magnetic fields, and how technology has evolved over time.

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and molecules, and laser-wielding scientists are revealing the action ...

Electrons play many roles in solid materials. When they are weakly bound and able to travel—i.e., mobile—they can enable electrical conduction. When they are bound, or "heavy," they can act as ...

The electrons and ions accumulated by satellites can eventually reach a high enough voltage to release discharge. ESD is already known to cause radio frequency pulses.

Theory Pseudopotential Approximation Within the PP approximation the Coulombic interactions between the valence electrons and the atomic nuclei and core electrons are replaced with effective ...

Lightning can be used to probe Earth’s dynamic Van Allen radiation belts, directly connecting terrestrial weather and space weather.

Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from swinging by the sun for a boost, just don't have the ability to scale to useful interstellar speeds.

An artistic representation of the first 3D metal-organic framework to simultaneously transport both electrons and protons, in which the tetrathiafulvalene rings and hydrogen bonds between ...

The first computer occupied the equivalent square footage of a small three-bedroom house—now we carry a more powerful computer in our pocket. Semiconductor innovations made the microchip possible.
