A physicist is a scientist who does research in physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made (particle physics) to the behavior of the material Universe as a whole (cosmology).
Famous quotes containing the word physicist:
“It would be a poor thing to be an atom in a universe without physicists, and physicists are made of atoms. A physicist is an atoms way of knowing about atoms.”
—George Wald (b. 1906)
