JAGDISH CHANDRA BOSE LIFE STORY

JAGDISH CHANDRA BOSE LIFE STORY  : –

Born  : – 30 November 1858, Memansingh, Bengal Presidency (now in Bangladesh)

Death  : –   3 November 1937

Work / Post  :- Scientist

Achievements  : –

An important role in the rendering of life theory in trees, pioneers in the field of radio and microwave optics.

 Indian scientist Professor Jagdish Chandra Bose was rich in versatility who played an important role in the invention of radio and microwave optics and the rendering of life theory in plants.  His genius can be gauged from the fact that apart from being a physical scientist, he was also a biologist, botanist, archaeologist and writer.  JC Bose was working at a time when science research work in the country was almost nil.  In such circumstances, Bose, rich in versatility, made a fundamental contribution in the field of science.  In view of his unique contribution and research in the field of radio science, ‘Institute of Electrical and Electronics Engineers’ (IEEE) considered him one of the fathers of radio science.  Although the inventor of radio was credited to Italian inventor Marconi, many physicists say that Professor Jagdish Chandra Bose was the real inventor of radio.  Jesse Bose’s observations and actions were used in the coming years.  Today’s radio, television, ground communication, remote sensing, radar, microwave oven and internet are thankful to Jagdish Chandra Bose.

Early Life  : –

 Acharya J.C.  Bose was born on 30 November 1858 in Rarauli village of Memansingh (now in Bangladesh).  His father Bhagban Chandra Bose served in various executive and magisterial positions in the British India Government.  At the time of Jagdish’s birth, his father was the Deputy Magistrate of Faridpur and it was here that Bose spent his early childhood.  He started his early education from a village school that his father had founded.  His father could have easily sent his son to a local English school but he wanted his son to learn the mother tongue and learn about his culture before learning the English language.  In the year 1869, he was sent to Kolkata (then Calcutta) where after spending three months in hair school, he got admission in St. Xavier’s College which was both a secondary school and a college.  In 1879, Bose left for London to study medicine after passing his BA examination in the Physics Group of the University of Calcutta, but due to poor health, he left London in January 1882 and moved to Cambridge, where he joined Christ’s College to study Natural Science.  .

Carrier  : –

 In the year 1884, Bose received a second class Bachelor of Arts in Natural Science and also a Bachelor of Science degree from London University.  On his return to India, he enrolled in the Presidency College, Kolkata in 1885.  He was the first Indian to be appointed as a Physics Professor at the Presidency College.  Although he was appointed, he was kept at half of the salary fixed for that post.  Bose opposed this discrimination and demanded the same salary that was paid to a European working in that position.  When his opposition was not considered, he refused to take the salary and continued without teaching for three years in his teaching work.  Ultimately, the officers fully realized Bose’s merit and character and made his appointment permanent from pre-date.  He was given a lump sum of salary for the last three years.

 He received his doctorate in science from the University of London in 1896.

 He continued his research at the Presidency College despite racial discrimination, despite the lack of funds and scientific instruments.  As a teacher, Bose was very popular among his students.  Many of his students in the Presidency College went on to earn a lot of name.  Chief among them were Satyendra Nath Bose and Meghnad Saha.

 After the year 1894, he devoted himself completely to research and experiments.  He converted a small enclosure adjacent to the bathroom into a laboratory at the Presidency College.  Here he carried out experiments involving refraction, diffraction and polarization.  It would not be wrong to call him the inventor of ‘wireless telegraphy’ as Bose publicly demonstrated his invention / research a year before Marconi’s invention patent (1895).

Discover  : –

 He created a very sensitive “K√∂hrer” (a device that imparts knowledge to radio waves).  They found that kohrer’s sensitivity was reduced when used continuously for a long period of time, and its sensitivity returned when used after a few intervals.  This led to the conclusion that metals also have emotion and memory.

 Jc  Bose was the first person to manufacture a device that could produce subtle waves that ranged from 25 millimeters to 5 millimeters and therefore his device was small enough to be carried anywhere in a small box.  He showed the world at that time a completely new type of radio wave, which was 1 centimeter to 5 millimeters, which is today called microwaves or micro waves.

 Jagdish Chandra Bose later engaged in the study of metals and plants.  Through his experiments, he showed that there is life in plants too.  He invented a device to record the pulse of plants.  In this experiment, he put a plant with root in a pot full of bromide (poison).  Subsequently, it was found that the pulse of the plant began to grow unstable.  Soon, the heartbeat became very fast and then stabilized.  The plant died due to poisoning.

Retirement After Time Life  : –

 After his retirement from Presidency College in the year 1915, he continued his research work and gradually shifted his laboratory to his home.  Bose Institute was established on 30 November 1917 and Acharya Jagdish Chandra Bose was its director till the last time of his life.

Death  : –

 Acharya Bose died on 3 November 1937 in Giridih (now in Jharkhand) of Bengal Presidency.  He was 78 years old at that time of his death.

 Like Acharya Bose, Bose Institute also engages in scientific research in various fields.  He not only illuminated the name of the country, but also instilled the urge of science in the minds of the next generation.

 The honor  : –

 He received his doctorate in science from the University of London in 1896

 He was elected a Fellow of the Royal Society’s in 1920

 In the year 1903, the British Government awarded Bose the Companion of the Order of the Indian Empire (CIE).

 In the year 191, he was awarded the Companion of the Order of the Ster India (CSI).

 In 1917, the British Government awarded him the title of Knight Bachelor.
