4. He was an Bengali polymath: a physicist, biologist, botanist,
archaeologist and Sci-Fi writer.
He pioneered the investigation of radio and microwave optics
IEEE named him one of the fathers of Radio science.
He was the first person from the Indian subcontinent to receive a US
patent, in 1904.
5. He was born in Bikrampur, Bengal, (now Munshiganj) on 30 November 1858.
He had his early education in village school in Bengal medium.
In 1869, Jagadish Chandra Bose was sent to Calcutta to learn English and was educated at
St. Xavier's School andCollege.
He passed the B.A. in physical sciences in 1879.
In 1880, he went to England to study medicine at LondonUniversity, England, but after a
year gave it up because of his own ill health.
In 1885, he returned from abroad with a B.Sc. degree and Natural ScienceTripos (a special
course of study at Cambridge).
He appointed officiating professor of Physics in Presidency College.
6. Not patented but he is the inventor ofWireless Telegraphy.
He fabricated a highly sensitive "coherer", the device that detects radio
waves.
Bose announced the development of a "iron-mercury-iron coherer with
telephone detector" in a paper presented at the Royal Society, London.
He had anticipated the existence of P-type and N-type semiconductors.
On September 14, 2012, Bose's experimental work in millimeter-band radio
was recognized as an IEEE Milestone in Electrical and Computer
Engineering.
7. Sir J.C. Bose did his original scientific work in the area of
Microwaves. He produced a compact apparatus for
generating electromagnetic waves of wavelengths 25 to
5 mm and studying their quasi-optical properties, such
as refraction, polarization and double refraction.
In 1895 J.C. rings a bell at a distance using
electromagnetic waves, proving for the first time in
history communication signals can be sent without using
wires.

In 1896 Bose is in London on a lecture tour and so is Marconi, who is conducting
wireless experiments for the British post office. In an interview, Bose also says he is not
interested in commercial telegraphy and others can use his research work.
8. Jagdish Chandra Bose showed experimentally plants too have life.
He invented an instrument to record the pulse of plants and connected it to a
plant.
He invented the Crescograph (A Crescograph is a device for measuring growth
in plants.) an electrical instrument that could measure the growth of a plant.
He founded the Bose Institute at Calcutta, devoted mainly to the study of
plants. Today, the Institute carries research on other fields too.
9. In 1896, Bose wrote Niruddesher Kahini, the first major
work in Bengali science fiction.
Later, he added the story in the Abyakta book as Palatak
Tuphan.
He is also considered the father of Bengali science fiction.

Garden on 25 June 2009 in honor of Jagadish Chandra Bose.
12. Bose died on 23 November 1937 at Giridih in Bihar.
We would like to end this presentation by quoting
Geddes : “The life-story of Jagadis Bose is worthy of
close and ardent consideration by all young Bangali
whose purpose is shaping itself towards the service of
science or other high cause of the intelligence or
social spirit.”
