Jagadish Chandra Bosu -
inventor of Radio, proof of plant, inorganic models
Physicist turned plant
biologist Jagadish Chandra Bose was born on 30 November 1858 in
Faridpur in Dacca District, Bangladesh to a well-to-do family.
Jagadishchandra Bose was born on the 30th of November 1858
in Faridpur in Dacca District. But Jagadishchandra Bose’s education
was really remarkable; it was dye to his father. In India and in other
countries there was a strong belief that only Westerners could achieve
anything worthwhile in science. Bose proved this wrong concept. He
showed that there were geniuses elsewhere too.
There is an interesting
story about a demonstration that Bose gave in England. On that day he
wanted to show some new things that he had found out. He had come to
the conclusion that plants can feel pain like animals; that when we
pinch them they suffer; and that they die in a few minutes after they
are poisoned. Bose wanted to show experiments to prove these
conclusions. A number of scientists and other leading men and women
had gathered to hear him. Bose started the experiments by injecting
poison into a plant. The plant should have shown signs of death in a
few minutes. On the contrary, nothing happened. The learned audience
started laughing. Even at this adverse moment Bose showed admirable
calmness. He thought quickly. The poison that he injected into the
plant did not kill it. So, he supposed that it would not hurt him
also. With full confidence he got ready to inject the poison into
himself. At that instant a man got up and confessed that instead of
poison he had put similar colored water. Now, Bose conducted the
experiment again with real poison, whereupon the plant withered and
died as expected.
scientific missions and gave lectures on
electromagnetic waves on living and nonliving matter,
plant physiology. Initiated detailed study of coherer leading to
his discovery of the common nature of electric response to all forms
of stimulation, in animal and plant tissues as well as in some
During the years
1894-1900, Bose performed pioneering research on
radio waves and created
waves as short as
5 mm. Bose’s work actually predates that of
Guglielmo Marconi who is most often associated with the
development of radio. Unlike Marconi who sought to commercialize his
work with radio waves, Bose was purely interested in radio waves as a
scientific endeavor. Bose also developed
generating, transmitting, and receiving radio waves
and used it to demonstrate conclusively the waves’ properties such as
reflection, total reflection, refraction, double refraction, and
polarization. Bose also experimented with galena to form an early type
diode, which may
be used as a
detector of electromagnetic waves.
After about 1900, Bose
began pursuing another longtime interest—animal and plant physiology.
His contributions to this field were pioneering. He introduced many
delicate and sensitive instruments, such as the
which was used for recording plant growth. It could magnify a small
movement as much as a million times. Plants grow every second by
1/50,000th of an inch! Electricity was then his special field of work.
He had successfully worked at transmitting electro-magnetic waves from
one place to another. He had determined the type of instruments
required both at the transmitting end and at the receiving end; he had
found out what the distance should be between these two ends. He was
using the instruments he had himself made. Bose demonstrated his
discoveries at the Royal Society in England.
In 1917 he founded the
Bose Research Institute in
Calcutta which was the first scientific research institute in India.
That same year a knighthood was conferred on Bose. In 1920 he became
the first Indian scientist to be elected to Great Britain’s
prestigious Royal Society.
The British Government
honored him more than once. In 1915 when retired from service he was
made an Emeritus Professor. He was honored as a Fellow of the Royal
Society (F.R.S) in 1920. In 1927 he presided over the Indian Science
