Acharya Sir Jagadish
Chandra Bose,30 November 1858 – 23 November 1937) was a Bengali polymath, physicist, biologist, botanist,
archaeologist, as well as an early writer of science fiction. He pioneered
the investigation of radio and microwave
optics, made very significant contributions to plant science, and laid the
foundations of experimental science in the Indian subcontinent. IEEE named him
one of the fathers of radio science. He is also considered the father of Bengali
science fiction. He also invented the
crescograph. A crater on the moon
has been named in his honour.
Born in Bikrampur (present day Munshiganj
District near Dhaka in Bangladesh) during the British Raj, Bose graduated from
St. Xavier's College, Calcutta. He then went to the University of London to
study medicine, but could not pursue studies in medicine due to health problems.
Instead, he conducted his research with the Nobel Laureate Lord Rayleigh at
Cambridge and returned to India. He then joined the Presidency College of
University of Calcutta as a Professor of Physics. There, despite racial
discrimination and a lack of funding and equipment, Bose carried on his
scientific research. He made remarkable progress in his research of remote
wireless signalling and was the first to use semiconductor junctions to detect
radio signals. However, instead of trying to gain commercial benefit from this
invention, Bose made his inventions public in order to allow others to further
develop his research.
Bose subsequently made a number of
pioneering discoveries in plant physiology. He used his own invention, the
crescograph, to measure plant response to various stimuli, and thereby
scientifically proved parallelism between animal and plant tissues. Although
Bose filed for a patent for one of his inventions due to peer pressure, his
reluctance to any form of patenting was well known. To facilitate his research,
he constructed automatic recorders capable of registering extremely slight
movements; these instruments produced some striking results, such as Bose's
demonstration of an apparent power of feeling in plants, exemplified by the
quivering of injured plants. His books
include Response in the Living and Non-Living (1902) and The Nervous
Mechanism of Plants
(1926).
Welcome to My Indian stamps, first-day covers and postcards gallery. These items have all been collected by me since the age of seven. My desire here, is to show as often as I can, some of my presumed beauties and talk about them. And hopefully make Your Day in the bargain. In case you want a better view, JUST CLICK on the picture and it will be ENLARGED. Please also see my picture postcards blog www.mypicturepostcards.blogspot.in, and also my stamps blog www.letstalkstamps.blogspot.com.
