World’s Top 20 Greatest Scientists of All Time

The world has seen advances in Science and technology in recent times. However, it has not come in a single day. The great minds of Science have worked since ancient times to shape up the future like this. There have been many scientists who contributed to make the world a better place to live. However, the major contributions of the scientists have been to know and understand the world better. Here are 20 greatest scientists who have changed the future and made the world better and advanced.

20. Paul Dirac

Paul Dirac

Paul Dirac, 1902- 1984, the great physicist is known for his early development of both quantum mechanics and quantum electrodynamics.

Linus Pauling is one of the famous Chemist and Biochemist who contributed for the Quantum Chemistry and Molecular Chemistry. He is one of the two persons in the world who won Nobel Prize for two different fields. He won Nobel Prize for the Chemistry and Peace. He has done great work on DNA Structures, Orthomolecular Medicine, Megavitamin Therapy and others. Linus Pauling, 1901-1994 is considered as one of the pioneering scientists in the world.

17. Werner Heisenberg

Werner Heisenberg

Werner Heisenberg, 1901-1976, is known for his Quantum Mechanism. He is famous for his Uncertainty Principle. He has created the Quantum Mechanics and won the Nobel Prize for Physics in 1932. He came to controversy for his work during World War II. He has done immense contribution to physics.

16. Franz Boas

Franz Boas

Franz Boas, 1858-1942, was one of the greatest scientists in the world. He is considered as the Father of American Anthropology. He was also one of the opponents of Scientific Racism. He also introduced the cultural relativism.

15. James Clerk Maxwell

James Clerk Maxwell

James Clerk Maxwell, 1831-1879, was a mathematical physics. He has great contribution for Electromagnetic Radiation; Magnetism and Maxwell’s equation of the Electromagnetism is called as one of the best thing in Physics. His most significant work on Physics is A Dynamic Theory of the Electromagnetic Field. He is considered as one of the best known scientists of modern physics.

14. Michael Faraday

Michael Faraday

Michael Faraday, 1791-1867, is known for his notable work on Electromagnetism and Electrochemistry. He discovered three of the most crucial things in the Electromagnetism. Electromagnetic Induction, diamagnetism and Electrolysis are the three major discoveries that changed the physics.

13. Nicolaus Copernicus

Nicolaus Copernicus

He was a revolutionary renaissance mathematician and astronomer. Nicolaus Copernicus 1473-1573, made the model of the universe and said that Earth is revolving around the Sun. He first injected the Science and Logic in the world.

12. Johannes Kepler

Johannes Kepler

Johannes Kepler, 1571-1630, was a renowned mathematician and astronomer who changed the science for space. He has given the foundation for the space research. Even Isaac Newton used his theories for Universal Gravitation.

11. Antoine Laurent Lavoisier

Antoine Laurent Lavoisier

He is one of the chemists who has huge influence in the field of chemistry and biology. He is called as the Father of Modern Chemistry. He coined the term Oxygen and Hydrogen. He was the scientist who first wrote list of elements and constructed the metric system. However, this is not the end as he also the person behind the modern chemical nomenclature. He was the first one to identify Sulfur as an element rather than compound. However, he is still known for his discovery that a matter changes the shape or the form but the mass remains the same.

10. Sigmund Freud

Sigmund Freud

Sigmund Freud, 1856-1939, is considered one of the greats in the field of psychology. He has defined the dreams, libido and many other things. His work on Transference is considered incredible. He formulated the Oedipus Complex and theory of Unconscious.

9. Marie Curie

Marie Curie

She was the first woman to win the Nobel Prize and the only person till now to win a Nobel Prize in two different category of science. She won the Noble Prize for Physics as well as for Chemistry. Her contribution to radioactivity is considered as the new beginning for the modern physics. She discovered two new elements Polonium and Radium.

8. Alan Turing

Alan Turing

Alan Turing, 1912-1954, was one of the earliest computer scientists and considered as the most influential one. The Turning Model is considered as the framework for the computer. He has huge influence over Algorithm and competence. He is also considered as the theoretical father of the Artificial Intelligence.

7. Niels Bohr

Niels Bohr

Niels Bohr, 1885-1962, a Danish Scientist made significant contribution towards the Quantum Theory and Atomic Structure. He received Nobel Prize for Physics. He proposed the most acceptable theory of atomic structure. Electrons are available in discrete energy levels around nucleus. The electrons jump one energy level to another. This is known as Bohr Model.

6. Max Planck

Max Planck

Max Planck, 1858-1947, is the most important name in Quantum Physics. His theories on the atomic and subatomic processes are not only vital but also revolutionary as well. The Plunk Constant is considered as one of the most important and frequently used constant in Physics. He won the Nobel Prize for Physics.

5. Charles Darwin

Charles Darwin

Charles Darwin, 1809-1882, was a geologist who is known for his theory of evolution. He established the fact the all the species have evolved from the descendents. His theory and explanation of natural selection and struggle for existence are considered as one of the best.

4. Galileo Galilei

Galileo Galilei

Galileo Galilei, 1564-1642, was one of the earliest scientists, mathematician, astronomers and may others. He is called as the Father of Observational Astronomy, father of physics and father of science as well. His contributions are many including phases of Venus, Sunspots and the satellites around Jupiter. He has tremendous contribution in Kinematics and Dynamics as well.

3. Nikola Tesla

Nikola Tesla

Nikola Tesla, 1856-1943, was a scientist who changed the specs of the world. His contribution for modern day Alternating Current and Electric Supply are immense and incredible.

2. Albert Einstein

His E = mc2 is one of the most important equation in quantum theory. His works on Photoelectric Effect, Photon theory of light, Particle Theory and Motion of Molecules are not only commendable but also game changing for physics.

1. Isaac Newton

Isaac Newton

Isaac Newton, 1642-1726, is the most prominent name in science. He was involved in so many things that it is hard to describe his work. However, his Laws of Motions, Universal Gravitation, Keepler’s Law of Planetary Motion, Heliocentric Model , Mechanics, Calculus in Mathematics, Binomial Series are considered on the best in the world. These are also very popular.

These great scientists have changed the way people look at it and these are greatest ever.
