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.
