Jagadis Chandra Bose

Bose, Jagadis Chandra

 

Born Nov. 30, 1858, in Bengal; died Nov. 23, 1937, in Giridih, Bengal. Indian plant physiologist, physicist, and biophysicist.

After graduating from college in Calcutta (1880) and Cambridge University in England (1885), Bose became a professor at Presidency College in Calcutta. In 1917 he founded a scientific research institute in Calcutta and served as its director; it now bears his name as the Bose Research Institute. In 1894–95, simultaneously with P. N. Lebedev, Bose constructed an electromagnetic damping wave generator with a diapason in both millimeters and centimeters. In particular, Bose’s instrument had a “spiral coherer,” which was used as an electromagnetic wave indicator. Bose used the instrument for research on the properties of electromagnetic waves and their effect on plants. His experiments helped to confirm the electromagnetic theory of light. Bose also researched electric contact phenomena. He established the analogy between plant and animal reactions to an external stimulus and gave a new explanation for the spontaneous contraction of plant tissues, the rise of fluid in stems, and other phenomena. He also studied photosynthesis and the water regime of plants.

This year, the Historical Exhibit features a rare and unique opportunity to view the original 60 GHz equipment used by the physicist Sir Jagadis Chandra Bose (1858-1937) of Calcutta, India, who performed some extraordinary experiments into the quasi-optical properties of mm-waves over a century ago.
At the same time, we encounter some of the contemporary players in the "revolving world factory" of 1920s Berlin: the Indian scholar Jagadis Chandra Bose, the theatre director Max Reinhardt, the pianist Lily Reiff, the satirist Georg Grosz; we are introduced to the Tibetan lamas who are her neighbors in the Saxon Inn, where they "inhabit almost the entire third floor" and occasionally run "with outstretched arms through the corridors of the hotel, frightening everyone with their ceremonial devils' masks.
