Physicist

Physicist

A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms.

History

The study of physics is a fundamental science and has been of central importance in the progress of scientific knowledge. The main fields of physics, along with their subfields and the theories and concepts they employ, are outlined below.

Fields of Specialization

Physicists can specialize in a number of different fields, including astrophysics, particle physics, nuclear physics, and biophysics. Albert Einstein, a physicist who is best known for developing the theory of relativity, is considered one of the most influential physicists in history.

Astrophysics

Astrophysics is the branch of physics that deals with the behavior, physical properties, and dynamic processes of celestial objects and phenomena.

Particle Physics

Particle physics is a branch of physics that studies the nature of particles that constitute matter and radiation.

Nuclear Physics

Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions.

Biophysics

Biophysics is an interdisciplinary science that applies approaches and methods traditionally used in physics to study biological phenomena.

Notable Physicists

Some of the most notable physicists include Isaac Newton, Albert Einstein, Niels Bohr, and Richard Feynman.
