Jagdish Chandra Bose, a great Indian scientist, experimental physicist, botanist and physiologist was born on November 30,1858. Bose went to England in 1880 for his higher studies and began to study medicine at the University of London, but changed the subject of his study and obtained a scholarship to study natural science at Christ College, Cambridge. Here one of his teachers was Professor Rayleigh, who had a great impact on Bose. Thereafter, he obtained his B.A. Degree from Cambridge and also a BSc from London University in 1884. Bose returned to India and took up a post of an officiating Professor of Physics at the Presidency College, Calcutta.
Bose caught the attention of all students and he became very popular among them. He took great interest in his students. Many of his students were destined to become famous later in their own right. Abala his wife helped and encouraged Bose in his studies, researches and teaching work. She also founded the Nari Siksha Samiti to spread education among women. She herself was highly educated and enlightened.
Bose always found time for research. Impressed by Sir Oliver Lodge?s book, Heinrich Hertz and his successors, he converted a small enclosure in the Presidency College into a laboratory. There he conducted his researches in refraction, diffraction and polarization. He developed use of galena crystals for making receivers. In 1895, he gave first public demonstration of electromagnetic waves and used them to ring a bell remotely and to explode gunpowder. Thus he demonstrated for the first time to an excited Calcutta audience, the wireless transmission of radio waves over a distance of 25 meters through masonry. This discovery was reported in 1896 in the Daily Chronicle of England. The first successful wireless signalling by Marconi in England did not happen till May 1897. J.C. Bose was fully aware of the commercial application of his discovery of wireless transmission and yet he did not exploit it because he was not interested in the material benefits. He kept his discoveries wide open for others to adopt them for practical and commercial purposes. Another notable work he did during that time was to discover the wavelength of electric waves by diffraction grating. These wonderful achievements caught the attention of the scientists of the world and won their appreciation and recognition. He sent his work in the form of a thesis to the Royal Society of London for publication. The thesis was of such fundamental scientific significance that the London University conferred on him the Degree of Doctor of Science.
It was during his painstaking research, he found out that continuous exposure of metals to electric waves caused fatigue or loss or sensitiveness to metals. He concluded this was similar to muscular fatigue in animals and also demonstrated the effects of chemical agents on living and nonliving substances.
He turned his attention from inorganic to organic and consequently his achievements as a plant physiologist proved far more remarkable than his radical achievements as a physicist. It was then he invented the wonderful Crescograph which has the enormity of 10 million magnifications. With the help of this instrument, J.C.Bose was able to prove and demonstrate that plant tissues also respond to stimuli in a way similar to animal tissues. His ideas on unity in the diversity of nature led to the modern science of cybernetics.
J.C.Bose was also a prolific writer and author of many books in addition to innumerable research papers. He was awarded with many national and international honours. In 1917, he was Knighted; the biggest honour bestowed by the British Kingdom and was also made Fellow of the Royal Society of London, the first Indian to secure this distinction in the field of science.
On 30 November, 1917, The Bose Research Institute was founded. The inaugural song was composed by no less a poet than Rabindranath Tagore and the painting that adorned the assembly hall was by the renowned painter Nandlal Bose. It is a premier Institute of research in India. University of Calcutta confirmed on him the titles ?Companion of Star of India? and ?Companion of the Indian Empire?. In 1926, he was nominated as a Member of the League of Nations Committee on Intellectual Cooperation. J.C.Bose dedicated the Bose Institute to the nation and delivered a memorable address ?The Voice of Life? on the inaugural day.
J.C.Bose, the great saint scientist died on 23 November, 1937.
