    bose subsequently made a number of pioneering discoveries in plant physiology. he used his own invention, the crescograph, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. although bose filed for a patent for one of his inventions because of peer pressure, his objection to any form of patenting was well known. to facilitate his research, he constructed automatic recorders capable of registering extremely slight movements; these instruments produced some striking results, such as quivering of injured plants, which bose interpreted as a power of feeling in plants. his books include response in the living and non-living (1902) and the nervous mechanism of plants (1926).

    in 2004, bose was ranked number 7 in bbc's poll of the greatest bengali of all time.[12][13][14]

Sir Jagadish Chandra Bose[1] CSI CIE FRS[2][3][4] (s/;[5], IPA: [dʒɔɡodiʃ tʃɔndro bosu]; 30 November 1858 – 23 November 1937[6]), also spelled Jagdish and Jagadis,[7] was a polymath, physicist, biologist, biophysicist, botanist and archaeologist, and an early writer of science fiction in British India.[8] He pioneered the investigation of radio and microwave optics, made significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent.[9] IEEE named him one of the fathers of radio science.[10] Bose is considered the father of Bengali science fiction, and also invented the crescograph, a device for measuring the growth of plants. A crater on the moon has been named in his honour.[11]

Born in Mymensingh, Bengal Presidency (present-day Bangladesh), during British governance of India,[6] Bose graduated from St. Xavier's College, Calcutta. He went to the University of London, England to study medicine, but could not pursue studies in medicine because of health problems. Instead, he conducted his research with the Nobel Laureate Lord Rayleigh at Cambridge and returned to India. He joined the Presidency College of the University of Calcutta as a professor of physics. There, despite racial discrimination and a lack of funding and equipment, Bose carried on his scientific research. He made remarkable progress in his research of remote wireless signalling and was the first to use semiconductor junctions to detect radio signals. However, instead of trying to gain commercial benefit from this invention, Bose made his inventions public in order to allow others to further develop his research.

Bose subsequently made a number of pioneering discoveries in plant physiology. He used his own invention, the crescograph, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. Although Bose filed for a patent for one of his inventions because of peer pressure, his objection to any form of patenting was well known. To facilitate his research, he constructed automatic recorders capable of registering extremely slight movements; these instruments produced some striking results, such as quivering of injured plants, which Bose interpreted as a power of feeling in plants. His books include Response in the Living and Non-Living (1902) and The Nervous Mechanism of Plants (1926).

In 2004, Bose was ranked number 7 in BBC's poll of the Greatest Bengali of all time.[12][13][14]
