BOSE JAGADISH CHANDRA
Physicist and Biologist (1858-1937)
Bose Jagadish Chandra, Jagadish additionally spelt Jagadis, (conceived November 30, 1858, Mymensingh, Bengal, India (presently in Bangladesh)— passed on November 23, 1937, Giridih, Bihar), Indian plant physiologist and physicist whose innovation of profoundly delicate instruments for the location of moment reactions by living life forms to outer upgrades empowered him to envision the parallelism among creature and plant tissues noted by later biophysicists. Bose's analyses on the semi optical properties of short radio waves (1895) drove him to make enhancements for the cohere, an early type of radio locator, which have added to the improvement of strong state material science.

After acquiring a degree from the University of Cambridge (1884), Bose filled in as a teacher of actual science (1885–1915) at Presidency College, Calcutta (presently Kolkata), which he left to establish and coordinate (1917–37) the Bose Research Institute (presently Bose Institute) in Calcutta.
To encourage his exploration, he developed programmed recorders equipped for enrolling amazingly slight developments; these instruments created some striking outcomes, for example, Bose's exhibition of an obvious intensity of feeling in plants, exemplified by the shuddering of harmed plants. His books remember Response for the Living and Non-Living (1902) and The Nervous Mechanism of Plants (1926).
Plant research
Bose Jagadish Chandra with other noticeable researchers from Calcutta University.
Bose led the greater part of his examinations in plant research on Mimosa pudica and Desmodium gyrans plants. His significant commitment in the field of biophysics was the showing of the electrical idea of the conduction of different upgrades (e.g., wounds, substance specialists) in plants, which were prior idea to be of a compound sort.
To comprehend the heliotrope developments of plants (the development of a plant towards a light source), Bose designed a torsional recorder. He found that light applied aside of the sunflower made turbot increment on the contrary side. These cases were later demonstrated tentatively.
He was likewise the first to examine the activity of microwaves in plant tissues and comparing changes in the phone film potential. He explored the component of the occasional impact on plants, the impact of substance inhibitors on plant upgrades and the impact of temperature.
Investigation of metal weariness and cell reaction
Bose played out a similar investigation of the weakness reaction of different metals and natural tissue in plants. He exposed metals to a blend of mechanical, warm, substance, and electrical upgrades and noticed the likenesses among metals and cells.
Bose's examinations exhibited a recurrent weakness reaction in both invigorated cells and metals, just as an unmistakable repetitive exhaustion and recuperation reaction across different sorts of boosts in both living cells and metals.
Bose archived a trademark electrical reaction bend of plant cells to electrical upgrade, just as the reduction and possible nonappearance of this reaction in plants treated with sedatives or toxin.
The reaction was additionally missing in zinc treated with oxalic corrosive. He noticed comparability in the decrease of flexibility between cooled metal wires and natural cells, just as an effect on the recuperation cycle time of the metal.
Sci-fi
In 1896, Bose composed Niruddesher Kahini (The Story of the Missing One), a short story that was later extended and added to Abyakta (অব্যক্ত) assortment in 1921 with the new title Palatka Tuphan (Runaway Cyclone). It was one of the primary works of Bengali sci-fi. It has been converted into English by Bodhisattva Chattopadhyay.
