Nuclear science is the study of sub-atomic particles and their application in various disciplines. Here you can learn about nuclear power plants, atomic theory and radiation.

What is an atomic clock and how does it work?

Many ads for new clocks advertise their ability to automatically synchronize themselves with the atomic clock in Boulder, Colorado. This atomic clock is more precise because it uses the frequencies of atoms as its resonator.
