According to the University of Oxford, the top 10 scientists of all time are:-
Sir Isaac Newton (1642-1726):
Newton was a polymath who explored a wide range of fields including mathematics, optics, physics and astronomy. In his Principia Mathematica, published in 1687, he laid the foundations of the cosmological system, explaining the laws of gravitation and motion.
Louis Pasteur (1822-1895):
He contributed greatly to the advancement of Western medicine by curing rabies, anthrax and other infectious diseases. Also discovered the process of pasteurisation to make milk safe to drink.
Galileo (1564-1642):
By building one of the first modern telescopes, Galileo revolutionized our understanding of the world, successfully proving that the Earth revolved around the Sun and not the other way around. His work laid the foundation for the two new sciences of mathematics and the dynamics of matter.
Marie Curie (1867-1934):
The discovery by Polish physicists and chemists helped to apply it to radiation and X-rays. He won the Nobel Prize in Chemistry and Physics.
Albert Einstein (1879-1955):
Revolutionized modern physics with his general theory of relativity. He won the Nobel Prize in Physics (1921) for his discovery of the Fotte electric effect, which formed the basis of quantum theory.
Charles Darwin (1809-1882):
Darwin developed his theory of evolution against a backdrop of disbelief and skepticism. He collected evidence for 20 years and published his conclusions in his The Origin of Species (1859).
Otto Hahn (1879-1968):
Hahn was a German chemist who discovered the atomic explosion (1939). He was a pioneering scientist in the field of radiochemistry and discovered radioactive materials and nuclear existentialism (1921). He won the Nobel Prize in Chemistry in 1944.
Nikola Tesla (1856-1943):
Tesla works on electromagnetism and AC current. He filed many patents ranging from electricity to radio transmission and played an important role in the development of modern electricity.
James Clerk Maxwell (1831-1879):
Maxwell made great strides in understanding electromagnetism. His research in electricity and mathematics laid the foundation for quantum physics. Einstein said about Maxwell, "James Clerk Maxwell's work changed the world."
Aristotle Aristotle (384 BC-323 BC):
Great Greek scientist who conducted many types of research in the natural sciences, including botany, astronomy, physics, astronomy, chemistry, meteorology and geometry.
