Molecules in water and other polar media are subject to strong electric forces. Such forces originate from their liquid environment, which at ambient temperature undergoes ultrafast structural ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...

Japanese engineers built a magnet-free electric motor with a plastic rotor, opening a surprising path for future machines.

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...
