The historical setting
Sir Jagadish Chandra Bose (30 November 1858 – 23 November 1937) was a polymath with interests in biology, physics and writing science fiction. He was a pioneer in the investigation of radio microwave optics, made significant contributions to botany, and was a major force behind the expansion of experimental science on the Indian subcontinent. Bose is considered the father of Bengali science fiction. A crater on the Moon was named in his honour. He founded the Bose Institute, a premier research institute in India and also one of its oldest. Established in 1917, the institute was the first interdisciplinary research centre in Asia. He served as the Director of Bose Institute from its inception until his death.
Born in Mymensingh, Bengal Presidency (present-day Bangladesh), during British governance of India, Bose graduated from St. Xavier's College, Calcutta (now Kolkata, West Bengal, India). Prior to his enrollment at St. Xavier's College, Calcutta, Bose attended Pabna Zilla School and Dhaka Collegiate School, where he began his educational journey. He attended the University of London to study medicine, but had to give it up due to health problems.
Microwave radio research
Bose became interested in radio following the 1894 publication of British physicist Oliver Lodge's demonstrations on how to transmit and detect radio waves. He began his own research in the new field in November 1894, setting up his equipment in small 20 ft sq room at Presidency College. Wanting to study the light-like properties of radio waves which were hard to study using long radio waves, he managed to reduce the waves to the millimetre level (in the microwave range of about 5 mm wavelength). Bose's research was not initially appreciated by his department at the college.
They felt he should focus only on teaching and that research involved neglect of his duties as a teacher, in spite of Bose giving 26 hours of weekly lectures. Later, when interest was generated in the wider scientific community, the Lieutenant-Governor of Bengal proposed a research post to help Bose. But this scheme was withdrawn when Bose voted against the government's stance during a university meeting. The Lieutenant-Governor persevered to have a Rs.2500 annual grant issued. Despite this, Bose struggled to find time for research due to his teaching duties.
In November 1895 at a public demonstration at the Town Hall of Kolkata, Bose showed how the millimetre range wavelength microwaves could travel through the human body (of Lieutenant Governor Sir William Mackenzie), and over a distance of 23 metres through two intervening walls to a trigger apparatus he had set up to ring a bell and ignite gunpowder in a closed room.
Plant research
Bose conducted most of his studies in plant research on Mimosa pudica and Desmodium gyrans plants. His major contribution in the field of biophysics was the demonstration of the electrical nature of the conduction of various stimuli (e.g., wounds, chemical agents) in plants, which were earlier thought to be of a chemical nature. In order to understand the heliotropic movements of plants (the movement of a plant towards a light source), Bose invented a torsional recorder. He found that light applied to one side of the sunflower caused turgor to increase on the opposite side. He was also the first to study the action of microwaves in plant tissues and corresponding changes in the cell membrane potential.
He researched the mechanism of the seasonal effect on plants, the effect of chemical inhibitors on plant stimuli and the effect of temperature. Bose performed a comparative study of the fatigue response of various metals and organic tissue in plants. He subjected metals to a combination of mechanical, thermal, chemical, and electrical stimuli and noted the similarities between metals and cells. Bose's experiments demonstrated a cyclical fatigue response in both stimulated cells and metals, as well as a distinctive cyclical fatigue and recovery response across multiple types of stimuli in both living cells and metals.
Bose documented a characteristic electrical response curve of plant cells to electrical stimulus, as well as the decrease and eventual absence of this response in plants treated with anaesthetics or poison.
Bose Institute
Jatras, which were popular ancient plays, sparked his interest in the stories of the Mahabharata and Ramayana. In the latter, he was particularly impressed by the character of Rama and even more so by the soldierly devotion of his brother Lakshmana. However, he found that most of the characters in these stories seemed too good and perfect. It was the elderly warriors of the Mahabharata, with their flaws and qualities that were both human and superhuman, who appealed more to his imagination as a boy.
