1. Isaac Newton
Newton invented classical mechanics, universal gravitation, and calculus — simultaneously. His Principia Mathematica (1687) is the most influential scientific book ever written. He was also the first to decompose white light into the spectrum and made foundational contributions to optics. No single individual has contributed more to physics.
2. Albert Einstein
Special relativity, general relativity, the photoelectric effect (Nobel Prize), stimulated emission (basis of lasers), and Brownian motion — in the same decade. Einstein's contributions span quantum mechanics and spacetime physics. His miracle year alone would rank him among the top physicists in history.
3. James Clerk Maxwell
Maxwell unified electricity and magnetism, predicted electromagnetic waves and their speed (the speed of light), co-founded statistical mechanics, and produced the first color photograph. Einstein kept Maxwell's portrait in his office. His impact on technology — all radio, microwave, and wireless technology — is incalculable.
4. Niels Bohr
Bohr's atomic model (1913) was the first successful quantum model; his Copenhagen interpretation defined the standard understanding of quantum mechanics for a century. His institute in Copenhagen trained a generation of quantum physicists.
5. Werner Heisenberg
Heisenberg invented matrix mechanics — the first complete formulation of quantum mechanics — and derived the uncertainty principle. His contributions are among the foundational results of modern physics despite the moral complications of his wartime role.
6. Paul Dirac
The Dirac equation predicted antimatter before it was observed — an extraordinary example of mathematics revealing physical reality. Dirac's quantum field theory contributions underpin the Standard Model of particle physics.
7. Michael Faraday
Faraday discovered electromagnetic induction (the basis of all electric generators and motors), invented the electric motor and the transformer, and established the field concept in physics. He had no formal mathematical education — all experimental genius.
8. Enrico Fermi
Fermi built the first nuclear reactor (Chicago Pile-1, 1942), made foundational contributions to nuclear physics and particle physics, and was equally outstanding theoretically and experimentally — an almost unique combination. He coined the term 'neutrino.'
9. Richard Feynman
Feynman developed QED (quantum electrodynamics), introduced Feynman diagrams, and contributed to superfluidity, the parton model, and quantum computing. His Feynman Lectures remain the clearest explanation of physics ever written.
10. Marie Curie
Curie discovered radioactivity as an atomic property, identified polonium and radium, built mobile X-ray units in WWI, and remains the only person to win Nobel Prizes in two different sciences. She overcame systematic sexism to become the most famous experimental physicist of the 20th century.
よくある質問
Who is considered the greatest physicist of all time?
Isaac Newton is most often ranked as the greatest physicist in history, having invented classical mechanics, universal gravitation, and calculus simultaneously in the 17th century. Albert Einstein is consistently second, with his contributions to relativity and quantum mechanics. The ranking depends on criteria: Newton for breadth and foundational impact, Einstein for conceptual depth and originality.
Where does Einstein rank among physicists?
Einstein is universally ranked among the top two or three physicists in history. His contributions include special relativity, general relativity, the photoelectric effect (Nobel Prize), and foundational quantum mechanics work. His miracle year of 1905 alone — four revolutionary papers — would rank any physicist among the all-time greats.
Who was the greatest experimental physicist?
Michael Faraday is often cited as history's greatest experimental physicist. With no mathematical training, he discovered electromagnetic induction, invented the electric motor and transformer, and established the field concept — all through experimental genius. Marie Curie and Ernest Rutherford are also strong candidates.
