• The inventor of wireless telecommunication, Sir Jagadish Chandra Bose was born on November 30, 1858 in British India's Bengal Presidency. 

• In November 1895, Bose presented a public demonstration at Town Hall in Calcutta, where he sent an electromagnetic wave across 75 feet, passing through walls to remotely ring a bell and to explode some gunpowder. 

• Bose is known as the father of wireless telecommunication. He had invented the Mercury Coherer, a radio wave receiver that was used by Guglielmo Marconi to build an operational two-way radio. 

• The science behind capturing radio waves was first demonstrated by Bose. While Marconi was celebrated for his invention, Bose remained unknown to many, as he never patented his work. 

• He was the first scientist to discover that plants too are living beings and have similar life cycles and functions like animals. 

• He invented the Crescograph, a device used to analyse and understand the functions of different stimuli in plants. 

• He conducted many chemical experiments to prove that plants can feel pain and react to affection and anger.
