Electrons are incredibly fast. Because of their ultrafast motions, directly observing their behavior has been challenging. Now researchers have suggested a new method to make visualizing electron ...

Electrons oscillate around the nucleus of an atom on extremely short timescales, typically completing a cycle in just a few ...

It may be the smallest, shortest chorus dance ever recorded. An international team of researchers observed how electrons, excited by ultrafast light pulses, danced in unison around a particle less ...

Atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...
