Sir Jagadish Chandra Bose

Father of the BengaliScience

Fiction &Inventor of

Cresco graph

Short description about him

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.

Born & Early Life In Short

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 and College.

He passed the B.A. in physical sciences in 1879.

In 1880, he went to England to study medicine at London University, 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 Science Tripos (a special course of study at Cambridge).

He appointed officiating professor of Physics in Presidency College.

About His Inventions In Short

Not patented but he is the inventor of Wireless 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.

About Radio Research

  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.

About plant research

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.

Science Fiction

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.

Death

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.”

Thanks Everybody
