Let's talk about some eminent scientists who have left an imprint on the world.

PLATO

Plato, (born 428/427 BCE, Athens, Greece—died 348/347, Athens), ancient Greek philosopher, student of Socrates (c. 470–399 BCE), teacher of Aristotle (384–322 BCE), and founder of the Academy, best known as the author of philosophical works of unparalleled influence.

Michael Faraday

Faraday became one of the greatest scientists of the 19th century and began his career as a chemist. 

His major contribution, however, was in the field of electricity and magnetism. He was the first to produce an electric current from a magnetic field, invented the first electric motor and dynamo.

Thomas Alva Edison

Thomas Edison was an American inventor who is considered one of America's leading businessmen and innovators. Edison rose from humble beginnings to work as an inventor of major technology, including the first commercially viable incandescent light bulb. He is credited today for helping to build America's economy during the Industrial Revolution. 

 John Ambrose Fleming

Sir John Ambrose Fleming  (29 November 1849 – 18 April 1945) was an English electrical engineer and physicist who invented the first thermionic valve or vacuum tube, designed the radio transmitter with which the first transatlantic radio transmission was made, and also established the right-hand rule used in physics

Albert Einstein

Albert Einstein was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics.  His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass-energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation"
