The attosecond is a tiny unit, but it has various potential applications: it can observe oscillating molecules, the chemical bonds formed by atoms in chemical reactions, and other extremely tiny and extremely fast things. One attosecond is equal to 1000 zeptoseconds, or 1/1000 femtosecond.

A femtosecond is a unit of time in the International System of Units (SI) equal to 10 −15 or 1 ⁄ 1 000 000 000 000 000 of a second; that is, one quadrillionth, or one millionth of one billionth, of a second. [1] A femtosecond is to a second, as a second is to approximately 31.69 million years.
Researchers found that people worldwide live 9.6 years longer than they are healthy — and in the U.S. the gap is more than 12 years.
High harmonic generation in krypton.This technology is one of the most used techniques to generate attosecond bursts of light. Attosecond physics, also known as attophysics, or more generally attosecond science, is a branch of physics that deals with light-matter interaction phenomena wherein attosecond (10 −18 s) photon pulses are used to unravel dynamical processes in matter with ...
