In the scientific world history, sir J.C. Bose was an milestone for Bengal science.
He was a versatile genious – a physicist, a botanist, biologist, an archaeologist and also
an amazing writer of science fiction. Born in Rarikhal in Bangladesh, Bangladesh, in
1858, he started his studies first in Hare school, then St. Xaviers’ school and St. Xaviers’
college. Later he went to London university for study in medicine and he studied natural
science in Christ’s college, Cambridge; University of Cambridge.
He became the professor of physics at Presidency college, Kolkata. He is crowned
as the inventor of first wireless detection device and for his pioneering research in
discovery of millimeters and microwaves. Bose developed ‘iron-mercury-iron coherer
with telephone detector’ through Royal Society of London. He measured wavelengths,
developed Galena detector, dielectric lenses, semiconductors of very high frequency
(60GHZ transmission system). He kept his bold steps also in development of receiver,
demonstration of propagation, refraction, polarization, photoelectric effect and effect of
millimeter waves in biology. He was a biophysicist also and founded ‘ Bose institute’ in
1917 which was probably the 1st modern research institute in India.
He was famous for his discussion in plant physiology (photosynthesis). He
invented ‘ Crescograph’ to measure plant response to various stimuli and proved
scientifically, parallelism between animal and plant tissues. Some of his classic reports on
photosynthesis are malate metabolism in Hydrilla, spectrophotometric estimation of

cholorophyls, spectral quantity for photosynthesis – indication of 2 photonsystems,
photoinactivation of photosynthesis and importance of flag leaf photosynthesis. There
was burst in biochemistry of carbon assimilation and photochemistry. Molecular biology,
genetic elucidation, transgenics, modeling all attained an new hight with the touch of
magestic thoughts of Sir J.C. Bose.
He established that ‘ electrochemical pulsations in living cells’ is responsible for
‘ascent of sap’ in plant bodies. His experiments expressed that plant grows faster in
pleasant music.
Bose is renowned as ‘father of Bengali science fiction’. In 1896, he wrote
‘Niruddesher Kahini’, then ‘Obbackto,’ Polatak Tufan’.
He was the first Indian scientist to get us patent in 1904. His creations and
researches till now haunt the modern science and technology. We are proud of our
scientist, Sir J.C.Bose.
