Bose and being ahead of the future: Illustrous History

bose J.C. Bose was the only scientist a century back, who had observed all properties in a coherer to qualify it as a memristor. He observes the pinched hystersis and resistance reversal, even though he couldn’t qualify the signal to do so.

  • In 1895 Bose gave his first public demonstration of electromagnetic waves, using them to ring a bell remotely (more than a mile) and to explode some gunpowder, proving for the first time in history communication signals can be sent without using wires.
  • Sir J. C. Bose invented the Mercury Coherer used by Guglielmo Marconi to receive the radio signal in his first transatlantic radio communication over a distance of 2000 miles from Poldhu, UK to Newfoundland, St. Johns in December 1901. Guglielmo Marconi was celebrated worldwide for this achievement, but in 1998, IEEE accepted J. C. Bose as the inventor of the mercury drop coherer used by Marconi.
  • Sir J. C. Bose holds the first patent worldwide to invent a solid-state diode detector to detect EM waves. It was based on galena crystal and is a part of study here.
  • Bose was also a pioneer in his work on microwave devices. His contribution remains distinguished in the field and was acknowledged by the likes of Lord Kelvin, Lord Rayleigh, etc.
  • He made numerous pioneering discoveries in plant physiology.
