Scientists have  enormous contribution in the advancement of human civilization.  Throughout the history of the world, many scientists have dedicated  their lives for research and innovation. Some of them even faced a lot  of torture for their theories but they continued their mission and thus  we are now in a modern world. I have made a list of 10 great scientists  in the history. Well, naturally, I had to leave out a lot of great  figures. However, I feel that my list represents some of the greatest scientists ever.  
   
   
  Aristotle
   
  Aristotle  is the Great philosopher who had a vast knowledge in different  disciplines. Studying different subject he contributed a lot in each of  those subjects. He contributed in physics, poetry, zoology, logic,  rhetoric, politics, government, ethics, and biology. This laurel Greek  philosopher was born in Stagira  in 384 BC. His father Nicomachus was a physician to the king Amyntas  III of Macedon’s court and it is believed that their ancestors also held  this position. Earlier in his life he was taught by his father at home  and the medical knowledge he got from his father led him to investigate  natural phenomenon later on. At the age of 18 he admitted in to the  young Greek aristocracy run by Plato, another Great Greek philosopher,  and Aristotle became the most favorite student of Plato.
   
  As a scientist Aristotle  made a good contribution which was very influential for the development  of the science over the year. Mainly he spent most of his life  researching the natural science and he did the researches without making  reference to the Mathematics which was later proven as the weakness of  his research by the scientists. His natural science oriented research  includes botany, zoology, physics, astronomy,  chemistry, and meteorology, geometry and many more. He was also the  teacher of the Great warrior Alexander the Great. This great philosopher  died n 322 BC.

Sir Isaac Newton
   
  Newton was also a man of versatile quality. He was physicist,  mathematician, astronomer, alchemist, and natural philosopher in a row.  His contribution in the development of science is a special one. He I  best known for his explanation of Universal Gravitation and three laws  of motion, and he was able to prove that the reason of both the motion  of objects on Earth and of celestial bodies are controlled by the same  Neutral laws. These findings could make a revolutionary change in the  development of science. In mechanical science his great contribution was  in optics. He could make a reflecting telescope. He also made some  research on light and stars. His research on General binomial Theorem  helped to be introduced today’s Calculus.
   
  Newton  was born to a farmer family but before three months of his birth his  father died and then he was brought up to his maternal grandmother as  her mother remarried. Newton could show his talent from his early life in The King’s School in Grantham and later he joined to the Cambridge University where he took his higher degrees.

Galileo Galilei
   
  Galileo is considered as one of the greatest  contributor to the development of Science. It is undoubtedly true that  Galileo could first helped science to come out of the trend of Aristotle. He was physicist,  astronomer, and philosopher and his best known contributions lie in the  development of Telescope, first two laws of motion and also in Astronomy. He is also considered as the father of astronomy, father of physics and father of science.
   
  He was born to a mathematician and musician father Vincenzo Galilei and his mother was Giulia Ammannati in Italy.  He was taught form his very early life. He was the first scientist who  followed the way of quantitative experiments in his research where the  result was based on mathematics. He had to suffer a lot from the church  for his theories.

Charles Robert Darwin
  There can be debate about whether Charles Darwin (12 February 1809 – 19 April 1882) is the greatest  scientist of all time but there is no doubt that he is the most  controversial scientist of all time. On the Origin of Species by Means  of Natural Selection (1859)- this is the book that has made Darwin immortal in the world history. This book has changed the course of science radically. It is perhaps an irony that Darwin studied theology and instead of becoming a clergy, he became naturalist. 
  Darwin  went to different parts of the world and carried out extensive  research. His theory about origin of human beings caused widespread  controversy. Darwin stated  that human beings have evolved through many changes and survival of the  fittest was in important factor in the development of animal world. Darwin’s theory still causes passionate debate among his supporters and opponents.

  Albert Einstein
   
  Einstein is the great scientist of the twentieth century and notable physicist of all time. It is told that he had learning disability  in his childhood. He could not talk till he was three and could not  read till he was eight. Despite such problems he later became the noble  prize winner for his contribution to the Physics. His theory of  relativity is considered as a revolutionary development of Physics. He  got Noble Prize in Physics in 1921 for his explanation of the  Photoelectric Effect and for his research in Theoretical physics.

Thomas Edison
   
  Edison  is the great inventor who has over 1000 patents and his inventions are  in various fields used in our daily life. In his early life he was  thought to have a learning disability and he could not read till he was twelve and later he himself admitted that he became deaf  after pulling up to a train car by his ears. He first could able to  turn the attention of the world after inventing Phonograph. His one of  the most popular invention is the Electric Bulb. He also developed the  telegraph system. His invention of carbon telephone transmitter  developed the carbon microphone which was used in the telephoned till  1980. He also became a prominent businessman and his business  institution produced his inventions and marketed the products to the  general people.

Alessandro Giuseppe Antonio Anastasio Volta
   
  Volta  was Italian physicist and he is best known for his contribution to the  development of electric battery. This benevolent scientist is also  regarded as one of the founder of the electric age. His parents sent him  to the Jesuit school intending to make him a Jurist. He also taught in  the University of Pavia  for 25 year. After that in 1800 he could make voltaic pile which could  produce steady electric current. He then worked on to develop the  electric bulb. For his work in the electric development he was given a  count by Napoleon. Emperor of Austria honored him naming him a professor of Philosophy at Padova. For his honor an electric unit Volt was named after him.

Stephen Hawking
   
  This famous scientist is considered as the greatest scientist of the twentieth century after Einstein. Haw king’s big bang theory and black hole theory has turned the attention of the world. He is the professor of Mathematics of the University of Cambridge. Though he is now about to be paralyzed, he is teaching through a computer  supported a machine by which his world are compiled. His physical  illness could not make him stop form his research. His famous book is “A  Brief History of Time”.

Louis Pasteur
   
  He  is one of the most famous contributors in the medical science. He first  introduced the germ theory of diseases. This is regarded as the base of  today’s microbiology. He found out some of the notion of the microbe  and he could find out that the viruses were not detectable through  microscope. Another important contribution of Pasteur is to protect  harmful microbes in a way called “Pasteurization” where harmful microbes  are destroyed by hitting the food. He is undoubtedly the most influential scientist in medical science.

  Sir Jagadish Chandra Bose
   
  He  was the first renowned Bengali scientist who had an important  contribution in the invention of Radio and microwave optics. He was born  in Mymensingh in Bengal which is the current Munshiganj District in Bangladesh. He studied in Hare school in Kolkata and then he got his B.A. in Science degree from Calcutta University. Then he went to England and got a B.A. degree from Cambridge University and a B.Sc. from London University. After coming back to the country he started teaching Physics in the Presidency College  at Kolkata. In his teaching career he had to prove his quality and  talent as he was the first Indian to teach Science at the college. In  1894 he started to research on Radio wave to make wireless communication  equipments. At the same time Italy’s Marconi also was researching on this project. He first invented "iron-mercury-iron  coherer with telephone detector" and he is the first person to use a  semiconductor junction to catch the radio waves. It is said that his  work on millimeter wavelength made him 50 years ahead. Considering such  things it is said that he was the real inventor of Radio but due to his  less seriousness towards patent and the communication gap made Marconi  to be regarded as the inventor of Radio.
   
  After  that he contributed in plant where he could make some vital theory of  ascent of sap. In this research he showed that some living cells in the  endodermis junction are the reason for the ascent of sap.

Guglielmo Marchese Marconi
   
  Marconi is a Nobel laureate physicist from Italy.  He is best known for his invention of Radio and he first introduced  wireless telegraph system. He was born to a landowner father Giuseppe  Marconi and his mother was Annie Jameson. He was very interested to  science form his early life. He initially started working on  electromagnetic wave or radio waves invented by Heinrich Hertz. Then  after a long research he could figure out such a technology to  communicate without wire. After his invention, he marketed this  equipment for the commercial purpose and at that time he got a  competitor free market in the U.S.
