2. Albert Einstein (Germany)
* Contribution: Developed the theory of relativity, including special and general relativity. Explained the photoelectric effect and Brownian motion. Won the Nobel Prize in Physics (1921).
3. Niels Bohr (Denmark)
* Contribution: Developed the Bohr model of the atom, which explained the structure of atoms and how they emit light. Made key contributions to quantum theory. Won the Nobel Prize in Physics (1922).
4. Werner Heisenberg (Germany)
* Contribution: Developed matrix mechanics, a fundamental formulation of quantum mechanics. Introduced the uncertainty principle, a cornerstone of quantum physics. Won the Nobel Prize in Physics (1932).
5. Erwin Schrödinger (Austria)
* Contribution: Formulated wave mechanics, an alternative yet equivalent description of quantum mechanics. Developed the famous Schrödinger equation. Won the Nobel Prize in Physics (1933).
6. Paul Dirac (England)
* Contribution: Developed the Dirac equation, a relativistic equation describing the behavior of electrons. Predicted the existence of antimatter. Won the Nobel Prize in Physics (1933).
7. Richard Feynman (USA, but of foreign descent)
* Contribution: Developed the theory of quantum electrodynamics (QED), which describes the interaction of light and matter. Known for his unique and engaging approach to physics teaching. Won the Nobel Prize in Physics (1965).
8. Hideki Yukawa (Japan)
* Contribution: Proposed the existence of mesons, particles mediating nuclear forces. Won the Nobel Prize in Physics (1949).
9. Subrahmanyan Chandrasekhar (India)
* Contribution: Developed the theory of white dwarf stars and their evolution. Made significant contributions to the study of stellar evolution and black holes. Won the Nobel Prize in Physics (1983).
10. Abdus Salam (Pakistan)
* Contribution: Developed the electroweak theory, unifying electromagnetic and weak forces. Won the Nobel Prize in Physics (1979).
