Sir Acharjo Jagadish Chandra Bose (1858-1937)
Who was this man? What did he do/achieve? And what does it mean to us?
His name came up in 4 of the BC "Forget Cricket" section threads. Many of us know him as a Bengali scientist of high international importance during the turn of century. We know him as a botanist maybe and some of us heard and read about him in our childhood as the scientist who first discovered and articulated the concept of plants having senses, i.e. responsive feelings! But he is much much more....This guy is much bigger than our centuries of collective imagination.

Sir Jagadish Chandra Bose is one of the most prominent first Indian scientists who proved by experimentation that both animals and plants share much in common. He demonstrated that plants are also sensitive to heat, cold, light, noise and various other external stimuli. Bose contrived a very sophisticated instrument called Crescograph which could record and observe the minute responses because of external stimulants. It was capable of magnifying the motion of plant tissues to about 10,000 times of their actual size, which found many similarities between plants and other living organisms.

Jagadish Chandra Bose was born on 30 November, 1858 at Mymensingh, now in Bangladesh. He was raised in a home committed to pure Indian traditions and culture. He got his elementary education from a vernacular school, because his father thought that Bose should learn his own mother tongue, Bengali, before studying a foreign language like English. Bose attended Cambridge after studying physics at Calcutta University. He returned to India in 1884 after completing a B.Sc. degree from Cambridge University.

Please read Varun Aggarwal from MIT on Scientist J.C. Bose, in his "SIR JAGADISH CHANDRA BOSE - The Unsung Hero of Radio Communication"

This is how Aggarwal said about Sir S.C. Bose' achievement...

Achievements of Sir J. C. Bose in the field of communication
•Sir J. C. Bose invented the Mercury Coherer (together with the telephone receiver) used by Guglielmo Marconi to receive the radio signal in his first transatlantic radio communication over a distance of 2000 miles from Poldhu, UK to Newfoundland, St. Johns in December 1901. Guglielmo Marconi was celebrated worldwide for this achievement, but the fact that the receiver was invented by Bose was totally concealed. Read Bose's original paper on the receiver device.
•In 1895, Sir J. C. Bose gave his first public demonstration of electromagnetic waves, using them to ring a bell remotely and to explode some gunpowder. He sent an electromagnetic wave across 75 feet passing through walls and body of the Chairman, Lieutenant Governor of Bengal. (I am in process of ascertaining how this experiment is placed in context of works by other scientists towards demonstrating remote transmission of EM waves).
•Sir J. C. Bose holds the first patent worldwide to invent a solid-state diode detector to detect EM waves. The detector was built using a galena crystal. Have a look at Bose's patent (...).
•Sir J. C. Bose was a pioneer in the field of microwave devices. His contribution remains distinguished in the field and was acknowledged by the likes of Lord Kelvin, Lord Rayleigh, etc. Read what people thought about J. C. Bose. Refer to (...).
