Guglielmo Marchese Marconi

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.

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.

Thomas Elva Edison

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.

Sir Jagadish Chandra Bose

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.

Louis Pasteur

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.
