3. Sir Jagadish Chandra Bose Father of the Bengali Science Fiction & Inventor of Cresco graph

4. 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.

5. 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.

6. 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.

7. 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. Diagram of microwave receiver and transmitter apparatus 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. 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.

9. 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.

10. Books Response in the Living and Non-living , 1902 Plant response as a means of physiological investigation, 1906 Comparative Electro-physiology : A Physico -physiological Study, 1907 Researches on Irritability of Plants , 1913 Physiology of the Ascent of Sap, 1923 The physiology of photosynthesis, 1924 The Nervous Mechanisms of Plants, 1926 Plant Autographs and Their Revelations, 1927 Growth and tropic movements of plants, 1928 Motor mechanism of plants, 1928

11. Honours Companion of the Order of the Indian Empire (CIE, 1903) Companion of the Order of the Star of India (CSI, 1912) Knight Bachelor (1917) Fellow of the Royal Society (FRS, 1920) Member of the Vienna Academy of Sciences, 1928 President of the 14th session of the Indian Science Congress in 1927. Member of Finnish Society of Sciences and Letters in 1929. Member of the League of Nations' Committee for Intellectual Cooperation Founding fellow of the National Institute of Sciences of India (now renamed as the Indian National Science Academy) The Indian Botanic Garden was renamed as the Acharya Jagadish Chandra Bose Indian Botanic Garden on 25 June 2009 in honor of Jagadish Chandra Bose.

12. 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.”
