释义
Bose, Sir Jagadis Chandra
Indian physiologist
born Nov. 30, 1858, Mymensingh, Bengal, India
died Nov. 23, 1937, Giridih, Bihār
Indian plant physiologist and physicist whose invention of highly sensitive instruments for the detection of minute responses by living organisms to external stimuli enabled him to anticipate the parallelism between animal and plant tissues noted by later biophysicists. Bose's experiments on the quasi-optical properties of very short radio waves (1895) led him to make improvements on the coherer, an early form of radio detector, which have contributed to the development of solid-state physics.
With a degree from the University of Cambridge (1884), Bose became professor of physical science at Presidency College, Calcutta (1885–1915), which he left to found and direct (1917–37) the Bose Research Institute, Calcutta. To facilitate his research, he constructed automatic recorders capable of registering extremely slight movements; these instruments produced some striking results, such as Bose's demonstration of an apparent power of feeling in plants, exemplified by the quivering of injured plants. His books include Response in the Living and Non-Living (1902) and The Nervous Mechanism of Plants (1926).
