A Physicist is a scientist who specializes in a Physics field.

**Example(s):**- Theoretical Physicists, such as:
- Galileo Galilei (1564-1642) who made pioneering contributions to the development of modern physics and observational astronomy, and supported the Copernican model of the solar system.
- Johannes Kepler (1571-1630) who is known for his laws of planetary motion, which provided one of the foundations for Newton's theory of universal gravitation.
- Christiaan Huygens (1629-1695) who made significant contributions to mechanics and wave theory, including the wave theory of light.
- Isaac Newton (1642-1727) who formulated the laws of motion and universal gravitation, laying the groundwork for classical mechanics.
- James Clerk Maxwell (1831-1879) who formulated the classical theory of electromagnetic radiation, bringing together electricity, magnetism, and light.
- Albert Einstein (1879-1955) who developed the theory of general relativity, fundamentally altering our understanding of gravity.
- Niels Bohr (1885-1962) who made foundational contributions to understanding atomic structure and quantum theory, including the Bohr model of the atom.
- Erwin Schrödinger (1887-1961) who is known for his contributions to quantum mechanics, particularly the Schrödinger equation and the famous thought experiment, Schrödinger's cat, which illustrates the principle of superposition.
- Werner Karl Heisenberg (1901-1976) who formulated the uncertainty principle, a fundamental concept in quantum mechanics that describes the limits of precision for simultaneous measurements of certain pairs of properties.
- Paul Dirac (1902-1984) who formulated the Dirac equation describing the behavior of fermions and predicted the existence of antimatter.
- Richard Feynman (1918-1988) who developed the path integral formulation of quantum mechanics and contributed to the theory of quantum electrodynamics.
- Stephen J. Hawking (1942-2018) who made groundbreaking contributions to black hole physics and cosmology, including Hawking radiation, which describes black holes emitting radiation due to quantum effects.
- Edward Witten (1951-) who is a leading researcher in string theory and has made many contributions to theoretical physics and mathematics.
- Lisa Randall (1962-) who has made significant contributions to particle physics and cosmology, including theories about higher dimensions and dark matter.

- Applied Physicists, such as:
- Marie Curie (1867-1934) who conducted groundbreaking research in radioactivity and discovered the elements polonium and radium.
- Enrico Fermi (1901-1954) who was known for his work on nuclear physics and the development of the first nuclear reactor.
- J. Robert Oppenheimer (1904-1967) who is often called the "father of the atomic bomb" for his role in the Manhattan Project and made significant contributions to quantum mechanics and nuclear physics.

**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.^{[1]}Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. They work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena.^{[2]}Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applied physics or engineering physics).
