J C Bose: A Satyagrahi Scientist

Subject :Science and Technology

Context: On the occasion of 164th birth anniversary of legendary Indian scientist Acharya Jagadish Chandra Bose and as part of Azadi Ka Amrit Mahotsava, Vijnana Bharati and Ministry of Culture, Govt. of India organized an “International conference on the contributions of J C Bose: A Satyagrahi Scientist”, at Inter-University Accelerator Centre, New Delhi.

Concept:

• Sir Jagadish Chandra Bose, born November 30, 1858, Bengal, India (now in Bangladesh).He was named the Father of Radio Science by the Institute of Electrical and Electronics Engineering.
• After earning a degree from the University of Cambridge (1884), Bose served as professor of physical science (1885–1915) at Presidency College, Calcutta (now Kolkata), which he left to found and direct (1917–37) the Bose Research Institute (now Bose Institute) in Calcutta.
• His books include Response in the Living and Non-Living (1902) and The Nervous Mechanism of Plants (1926).

His contributions:

• In 1900, his paper titled “On the Similarity of Responses in Inorganic and Living Matter” at the International Congress of Physics, Paris garnered huge appreciation,led to the discovery of the common nature of the electrical response to all forms of stimulation, in animal and plant tissues as well as in some inorganic models.
• He was  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.Bose was thus a key figure in the invention of the modern radio and also in sonic technology.
• He was the first to demonstrate the wireless transmission and reception of electromagnetic waves
• He was knighted in 1917 and elected the Fellow of the Royal Society in 1920 for his amazing contributions and achievements.
