Top 10 Physicists Of All Time

Physics considered the father of science, tries to answer the biggest questions, how the universe came about, why it exists? and how it will end? it dares to read nature, tape the mind of God. And only the finest brains, men of pure curiosity dare to unweave the tapestry of nature. Check out the top 10 physicists of all time and look at what their contributions are.

1. Albert Einstein

Albert Einstein, his name synonymous with Genius, was a German-born Jewish theoretical physicist. He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed “the world’s most famous equation”),he received the 1921 Nobel Prize in Physics “for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect”.The latter was pivotal in establishing quantum theory.

2. Isaac Newton

Sir Isaac Newton  was an English physicist and mathematician who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica (“Mathematical Principles of Natural Philosophy”), first published in 1687, laid the foundations for classical mechanics. Newton also made seminal contributions to optics and shares credit with Gottfried Leibniz for the invention of infinitesimal calculus. He was knighted with the title Sir by Queen Anne in 1705. Newton died at the age of 84, in 1727.

3. Max Planck

Max Karl Ernst Ludwig Planck was a German theoretical physicist who originated quantum theory, which won him the Nobel Prize in Physics in 1918.Planck made many contributions to theoretical physics, but his fame rests primarily on his role as originator of the quantum theory. This theory revolutionized human understanding of atomic and subatomic processes, just as Albert Einstein’s theory of relativity revolutionized the understanding of space and time. Together they constitute the fundamental theories of 20th-century physics.

4. Michael Faraday

Michael Faraday was an English scientist who contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis. Although Faraday received little formal education, he is one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the basis for the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.He similarly discovered the principle of electromagnetic induction, diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became practical for use in technology.

5. James Clerk Maxwell

James Clerk Maxwell ) was a Scottish mathematical physicist. His most prominent achievement was to formulate a set of equations that describe electricity, magnetism, and optics as manifestations of the same phenomenon, namely the electromagnetic field. Maxwell’s achievements concerning electromagnetism have been called the “second great unification in physics”,after the first one realised by Isaac Newton. Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. Maxwell proposed that light is in fact undulations in the same medium that is the cause of electric and magnetic phenomena. Maxwell helped develop the Maxwell–Boltzmann distribution, which is a statistical means of describing aspects of the kinetic theory of gases. He is also known for presenting the first durable colour photograph in 1861 and for his foundational work on analysing the rigidity of rod-and-joint frameworks (trusses) like those in many bridges.


6. Richard Feynman

Richard Phillips Feynman  was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics (he proposed the parton model). For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world.

7. Erwin Schrodinger

Erwin Rudolf Josef Alexander Schrödinger was an Austrian physicist who developed a number of fundamental results in the field of quantum theory, which formed the basis of wave mechanics: he formulated the wave equation (stationary and time-dependent Schrödinger equation) and revealed the identity of his development of the formalism and matrix mechanics. Schrödinger proposed an original interpretation of the physical meaning of the wave function and in subsequent years repeatedly criticized the conventional Copenhagen interpretation of quantum mechanics (using e.g. the paradox of Schrödinger’s cat).In addition, he was the author of many works in various fields of physics: statistical mechanics and thermodynamics, physics of dielectrics, color theory, electrodynamics, general relativity, and cosmology, and he made several attempts to construct a unified field theory.

8. Paul Dirac

Paul Adrien Maurice Dirac  was an English theoretical physicist who made fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics. He was the Lucasian Professor of Mathematics at the University of Cambridge, a member of the Center for Theoretical Studies, University of Miami, and spent the last decade of his life at Florida State University. Among other discoveries, he formulated the Dirac equation, which describes the behaviour of fermions and predicted the existence of antimatter. Dirac shared the Nobel Prize in Physics for 1933 with Erwin Schrödinger, “for the discovery of new productive forms of atomic theory”.He also did work that forms the basis of modern attempts to reconcile general relativity with quantum mechanics.

9. Ernest Rutherford

Ernest Rutherford, was a New Zealand-born British physicist who became known as the father of nuclear physics.Encyclopædia Britannica considers him to be the greatest experimentalist since Michael Faraday (1791–1867). In early work he discovered the concept of radioactive half-life, proved that radioactivity involved the transmutation of one chemical element to another, and also differentiated and named alpha and beta radiation.This work was done at McGill University in Canada. It is the basis for the Nobel Prize in Chemistry he was awarded in 1908 “for his investigations into the disintegration of the elements, and the chemistry of radioactive substances”

10.  Werner Heisenberg

Werner Karl Heisenberg was a German theoretical physicist and one of the key creators of quantum mechanics. In 1927 he published his uncertainty principle, upon which he built his philosophy and for which he is best known. Heisenberg was awarded the Nobel Prize in Physics for 1932 “for the creation of quantum mechanics”. He also made important contributions to the theories of the hydrodynamics of turbulent flows, the atomic nucleus, ferromagnetism, cosmic rays, and subatomic particles, and he was instrumental in planning the first West German nuclear reactor at Karlsruhe, together with a research reactor in Munich, in 1957.
