“Wireless” wizard – Marconi
Guglielmo Marconi Marchese (1874 to 1937) “Father of Wireless” was born in Italy in the year 1874, got educated in physics.
Young Marconi took keen interest in Heinrich Hertz’s experiments on electromagnetic waves which stimulated newer ideas in Marconi’s mind that such waves could be transmitted without connection of wires.
Actually Heinrich Hertz laid the foundation for radio, television and radar.
One night in 1894 Guglielmo Marconi did an experiment in the presence of his mother. In a room he positioned an electric bell and a Morse key 30 feet apart; on pressing the key the bell rang.
Next he placed his self-made ‘transmitter set’ on one side of a hill and the ‘receiver’ on the other side. Messages were transmitted.
By 1897 Guglielmo Marconi could transmit radio messages upto a distance of 12 miles.
The principle of the electric telegraph and radio (wireless set) was the same. Messages could be sent without the intervention of wires; hence the name “wireless”. The term “radio” is confined to the communications system transmitting audio signals (wireless).
Such a frustration for a scientist is not uncommon in one’s own career, on his own soil! Notwithstanding this, he patented this machine in London.
Subsequently he founded his “Wireless telegraph company”. In 1899 he transmitted radio signals across the English channel, a distance of about 31 miles.
In 1900 he cleverly got patented his four-circuit tuningset.
In 1901 radio-wave signals were sent from Newfoundland to Cornwall in England; he sent signals across the Atlantic.This was a great day in the history of “wireless “.
Scientist Guglielmo Marconi shared the Nobel Prize for physics in 1909.
When he died in Rome in 1937, a two-minute silence was observed by all radio stations throughout the world.
This bears testimony to the honour people bestowed on this great scientist in recognition of the razzmatazz.
In the present day :
All India Radio, BBC (British Broadcasting Corporation) feed news items punctual on time. People are benefited by the broadcast.
In the early part of the 20th century radio was a craze; now TV has replaced radio — with evolution of time and gadgets, niceties also improve,[analogy : Computer jeering typewriter].
Tuning the radio was a status symbol at one time; now, of course, switching on TV has become a more prestigious life style. Live telecast is the norm of the present day.
