Jagdish Chandra Bose

Born in Mymensingh, Bengal, in November 30, 1858, Bose went to England to study medicine at the University of London. He returned to India with a B.A degree from Cambridge and a B.Sc from the London University and started experiments involving refraction, diffraction and polarisation.

Sir J.C. Bose did his original scientific work in the area of Microwaves. He produced extremely short waves and done considerable improvement upon Hertz's detector of electric waves. He produced a compact appratus for generating electromagnetic waves of wavelengths 25 to 5 mm and studying their quasioptical properties, such as refraction, polarization and double refraction.

Bose turned his attention from electromagnetic waves to response phenomena in plants by the end of the 19th century. Bose's research on response in living and non-living led to some significant findings: in some animal tissues like muscles, stimulation produces change in form as well as electrical excitation, while in other tissues (nerves or retina), stimulation by light produces electric changes only but no change of form. He showed that not only animal but vegetable tissues under different kinds of stimuli-mechanical, application of heat, electric shock, chemicals, drugs- produce similar electric responses.

He was appointed Professor Emeritus after he retired from the Presidency College in 1915. The Bose Institute was founded a couple of years later. He was also elected Fellow of the Royal Society in 1920. In 1937 Jagdish Chandra Bose passed away at Giridih in Bihar.
