Unsung Hero of Radio Communication

Spotlight

Who: Sir Jagadish Chandra Bose

Highest educational qualification: Natural Science Tripos (BA) from Christ's College, UK

Areas of research: Refraction, diffraction and polarization of light, electromagnetic waves, semi conductors and response phenomena in plants.

Best remembered for: Being the first person in the world, to find a device that generates micro-waves of very short wavelength. He developed the use of galena crystals for making receivers, both for short wavelength radio waves and for white and ultraviolet light. He subsequently became the first Indian to be awarded a US Patent (Patent No. US. 755840 issued in 1904).

Summary of research: Bose researched the mechanism of the seasonal effect on plants, the effect of chemical inhibitors on plant stimuli and the effect of temperature. He demonstrated 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. He also studied the action of microwaves in plant tissues and corresponding changes in the cell membrane potential and hypothesized that plants can "feel pain and understand affection".

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.

Honors:

  • Knight Bachelor (1917)
  • Fellow of the Royal Society (FRS 1920)
  • President of the 14th session of the Indian Science Congress in 1927
  • Founding fellow of the National Institute of Sciences of India (now the Indian National Science Academy)

Personal interest: In 1896, Bose wrote Niruddesher Kahini, the first major work in Bengali science fiction. Later, he added the story in the Abyakta book as Palatak Tuphan. He was the first science fiction writer in the Bengali language.

Trivia: Recently, he has been acknowledged by IEEE (USA) as one of the pioneers in the discovery of radio.
