Etymology

Origin of physicist

First recorded in 1710–20; physic(s) + -ist

Explanation

A physicist is a scientist who studies and is trained in physics, which is the study of nature, especially how matter and energy behave. Do you ever wonder how things work? If you're interested in what makes magnets attract iron or what's happening in atoms, then maybe you should become a physicist. Physicists study physics, which is related to the word physical. Physicists are interested in everything that physically exists, from tiny gadgets to massive stars. It takes many years of school to become a physicist, and physicists work on complex projects such as space travel and new energy sources.
