A D V E N T U R E S in C Y B E R S O U N DJagadis Chundeer Bose : 1858-1937
Jagadis Chundeer Bose born East Bengal India November 30, 1858 and died in Bengal India November 23, 1937. He was once referred to as Marconi's immediate predecessor. He was a Hindu physicist and botanist. He graduated from Cambridge and went back to Calcutta to be a physics professor [He got into something called] where he worked on a system he called 'wave telegraphing'. During a lecture in Calcutta he demonstrated the ability of electric waves to penetrate walls of wood and brick. His radiator was a small platinum ball between two small platinum beads, connected to a two volt battery. When a key was pressed the ball sparked and as he explained
...started a wave through the ether in all directions like a wave produced by dropping a stone into a pond. The Bose receiver was about seventy five feet distant from the radiator with three thick walls between them yet the electric wave was made to fire a pistol and ring a bell. The energy was concentrated as rays of light are concentrated by a lens placed close to the radiator. Bose used lenses of various materials sulphur, ebonite and pitch. He was asked what is the law describing the intensity or power of the wave at any given distance? he replied exactly the same as the law of light. He was then asked
... do you mean to say that you could telegraph in this way through houses as far as you could send a beam of light with a searchlight? He replied...The above questions were taken from an 1897 interviews in McClures magazine. In 1915 he founded the Bose research institute for the study of plant and insect life. He built a Crescograph which was a recorder that could detect any nervous reaction in a plant and then multiply it by ten million times [it appears his love of plants was far greater].
