Top 20 Greatest Scientists and Their Inventions That Changed the World

Mankind has progressed immensely over the period of time and the great contributions by some men in the field of science have played a key role in this growth and transition. These great scientists have made some amazing inventions and discoveries which have changed the way we live. These people do deserve a tribute from us mankind and thus we’ve set our blog in a tributary for great scientists for today.

Read along for the list of top 20 most famous scientists who changed the world.

20. Luis Alvarez

Luis Alvarez

Luis Alvarez gained fame when he discovered the iridium layer and his theory on dinosaurs. He was the first to expedite the extinction of dinosaurs after a large meteorite hit the Earth. He also invented the Microwave Phased Array Antenna, that has helped in eradicating hostilities in airspace due to poor weather conditions. He was awarded Nobel Prize in Physics for his dignified work in particle physics.

19. Wilhelm Roentgen

Wilhelm Roentgen

William Rontgen was a physics professor who the first person to discover the X-rays. He generated X-Ray photography within two weeks of discovering the X-ray functioning. He helped shape successful transformation and diagnosis of bone injuries and diseases. He was awarded an honorary degree in medicine for his discovery of X-ray. He also earned Nobel Prize in Physics in 1901.

18. William Crookes

William Crookes

William Crookes was a physical chemist who went onto discover the element thallium. He further invented the Crookes tube, which is used to generate so-called cathode rays. Crookes tube is an evacuated electrical discharge tube which is facilitated to stream electrons via cathode rays. Crookes tube normally uses magnetic fields which consist of negatively charged particles.

17. Lord Kelvin

Lord Kelvin

Next up on the list is William Thomson who is also known as Lord He was the first person to codify the first two laws of thermodynamics. He deduced the absolute zero of temperature, i.e. -273.15 degree Celsius. Adhering to his work in temperature phenomenon, he was honored with Kelvin temperature scale whereby the absolute zero is termed as O degree, Kelvin. He was also a physics professor who devised equipment and invented many devices. He also patented the transatlantic telegraph signaling via undersea cable.

16. James Clerk Maxwell

James Clerk Maxwell

James Clerk Maxwell was a Scottish Mathematical physicist who founded the concept of electromagnetic field. He devised a set of equations that helped clarify the electronic field. He was the first person to take a color photograph after devising his study in optics and speed. His work laid the foundation for the thermodynamics and kinetic theory. One such development was Maxwell-Boltzmann distribution which set in relativity and quantum mechanics. His work led him to be regarded as a prominent physicist.

15. Robert Hooke

Robert Hooke

Robert Hooke was the one who discovered the Hooke’s Law- the law of elasticity. He also invented the balance spring which has been vital in displaying accurate timekeeping in pocket watches. He also discovered plant cells in his early expedition as a scientist. Furthermore, he invented the machine that cut teeth for cogs used in the watch mechanism.

14. Stephen Hawking

Stephen Hawking

A modern day great theoretical physicist and cosmologist, Stephan Hawking has been the face of gravitational singularity theorems. He has also given the theoretical explanation to the Hawking radiation, the phenomenon dealing with black holes emitting radiation. He is a vocal advocate of many world’s interpretations of quantum physics. He was awarded Presidential Medal of Freedom for his works.

13. Sir Jagadish Chandra Bose

Jagadish Chandra Bose

Named as Jagadish Chandra Bose or simply J.C. Bose was a polymath, physicist, biologist, botanist, archaeologist and an early science fiction writer. He is known for his innovative invention Cresco-graph which pioneered discoveries in plant physiology. He was also the first person to use semiconductor junctions to detect radio signals.

12. Michael Faraday

Michael Faraday

Michael Faraday is known for his discoveries on electromagnetic inductions and rotations. He further elaborated the via magnetization and magneto-optical effect. It was his outing that led to the electric motor and Faraday’s ring. After having to leave school at fourth grade, he joined theworkforce as a bookbinder and taught himself to read and write. He wrote books on ‘Experimental Researches in Electricity’ and ‘Chemical History of Candle’.

11. Aristotle

Aristotle

A famed biologist, zoologist, ethicist, poet and political scientist, Aristotle was a profound master of rhetoric and logic. He has theories in physics and metaphysics that are held with high regard to this day. Although only a few of his teachings and discoveries have been kept intact till date, his elaboration on matters of science is highly sought. He was a student of the great Plato and a tutor to Alexander the Great.
