(Pankaj Kapoor in "Ek Doctor Ki Maut")

"Ek Doctor Ki Maut" is a 1990 award-winning Hindi film starring Pankaj Kapur, Shabana Azmi, Anil Chatterjee and Irfan Khan in lead roles by noted Bengali director Tapan Sinha, which depicts the ostracism, bureaucratic negligence, reprimand and insult of a doctor and his research, instead of recognition. The film is based on the story "Abhimanyu" by Ramapada Chowdhury and is loosely based on the life of Dr. Subhash Mukhopadhyay, an Indian Physician who pioneered the In vitro fertilisation treatment just around the same time when another leading scientist Dr. Robert Edwards was conducting separate experiments in England.


Subhash Mukhopadhyay (16 January 1931 – 19 June 1981) was an Indian Bengali scientist, physician from Hazaribagh, Jharkhand, who created the world's second and India's first child (Durga) using in-vitro fertilization. Kanupriya Agarwal (Durga), who was born in 1978, just 67 days after the first IVF baby in United Kingdom. Afterwards, Dr. Subhash Mukhopadhyay was harassed by the then West Bengal State government and Indian Government and not allowed to share his achievements with the international scientific community. Dejected, he committed suicide on 19 June 1981.

Along with M. S. Swaminathan and B. Sivaraman, Subramaniam was the architect of India's modern agricultural development policy, after the success of his programme which led to a record production of wheat in 1972 termed as the Indian Green Revolution. As Minister for Food and Agriculture, he introduced high-yielding varieties of seeds and more intensive application of fertilizers which paved the way for increased output of cereals and attainment of self-sufficiency in food-grains in the country.





4. B. Indian Institute of Technology, Kharagpur


The Indian Institute of Technology Kharagpur is a public technical and research university established by the Government of India in 1951. It is the first of the IITs to be established and is recognized as an "Institute of National Importance". In 2019, it was awarded the status of "Institute of Eminence".

(Main Building of IIT, Kharagpur)

The institute was initially established to train scientists and engineers after India attained independence in 1947 as result of recommendation by a Committee led by Sir Jogendra Singh. On the grounds that West Bengal had the highest concentration of industries at the time, Bidhan Chandra Roy, the Chief Minister of West Bengal, persuaded Jawaharlal Nehru (India's first prime minister) to establish the institute in West Bengal. The first Indian Institute of Technology was thus established in May 1950 as the "Eastern Higher Technical Institute". It was located in Esplanade East, Calcutta, and in September 1950 shifted to its permanent campus at Hijli, Kharagpur 120 kilometres south-west of Kolkata. Hijli had been used as a detention camp during the British colonial rule in India, to keep Indian freedom fighters captive.

The name "Indian Institute of Technology" was adopted before the formal inauguration of the institute on 18 August 1951 by Maulana Abul Kalam Azad.

“Aryabhata”, India's first indigenously built satellite was launched on 19 April 1975 from Kapustin Yar, a Russian rocket launch and development site in Astrakhan Oblast using a Kosmos-3M launch vehicle. It was built by the Indian Space Research Organisation under the leadership of U.R. Rao. The launch came from an agreement between India and the Soviet Union directed by UR Rao and signed in 1972.



The satellite was named after the 5th century astronomer and mathematician “Aryabhata”. The satellite's image appeared on the reverse of Indian two rupee banknotes between 1976 and 1997.






2. C. Prafulla Chandra Ray





Acharya Prafulla Chandra Ray (2 August 1861 – 16 June 1944) was a Bengali chemist, educationist, historian, industrialist and philanthropist. A leading Bengali nationalist, he established the first Indian research school in chemistry and is regarded as the “father of chemical science in India”. Showing great promise in his studies as a young man in Bengal, he was awarded a fellowship to the University of Edinburgh in 1882, where he received his BS and then his PhD in 1887. In a day when organic chemistry was all the rage, he chose to pursue inorganic chemistry, becoming an expert in mineral salts, such as sulfates and nitrites.


The Royal Society of Chemistry honoured his life and work with the first ever “Chemical Landmark Plaque” outside Europe. He was the founder of “Bengal Chemicals & Pharmaceuticals”, India's first pharmaceutical company. He is the author of “A History of Hindu Chemistry from the Earliest Times to the Middle of Sixteenth Century” (1902).


(First page of Chandra Ray’s paper on nitrites of mercury, in which he announced his discovery of “mercurous nitrite” in “Journal of the Chemical Society of London”, 1897)



In 1897, he announced a major discovery of a new compound, “mercurous nitrite” through an article, which was published in several papers and Journals drawing attention worldwide.





3. A. 1729

“Hardy-Ramanujan Number” – (1729) is the smallest nontrivial "taxicab number", i.e., the smallest number representable in two ways as a sum of two cubes. It is given by:
                                           1729=1^3+12^3=9^3+10^3
So far, six taxicab numbers are known. They are:

The Hardy-Ramanujan number is named such after an anecdote of the British mathematician G.H. Hardy who had gone to visit Srinivasa Ramanujan (22 December 1887 – 26 April 1920), Indian mathematician in hospital. The anecdote is a part of Ramanujan's biography 'The Man Who Knew Infinity' by Robert Kanigel. Mr. Hardy quipped that he came in a taxi with the number '1729' which seemed a fairly ordinary number. Ramanujan said that it was not. 1729, the Hardy-Ramanujan Number, is the smallest number which can be expressed as the sum of two different cubes in two different ways.

Srinivasa Ramanujan, who lived only 32 years, had almost no formal training in pure mathematics, he made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions, including solutions to mathematical problems then considered unsolvable.





4. A. Satyendra Nath Bose


Satyendra Nath Bose, (1 January 1894 – 4 February 1974) was an Indian physicist specialising in theoretical physics. He is best known for his work on quantum mechanics in the early 1920s, providing the foundation for "Bose–Einstein statistics" and the theory of the Bose–Einstein condensate. A Fellow of the Royal Society, he was awarded India's second highest civilian award, the Padma Vibhushan in 1954 by the Government of India.

The class of particles that obey Bose–Einstein statistics, "bosons" (also known as "God Particle"), was named after Bose by Paul Dirac.

A polymath, he had a wide range of interests in varied fields including physics, mathematics, chemistry, biology, mineralogy, philosophy, arts, literature, and music. He served on many research and development committees in sovereign India.



5. A. C. V. Raman

Sir Chandrashekhara Venkata Raman (7 November 1888 – 21 November 1970) was an Indian physicist who made ground-breaking works in the field of light scattering. With his student K. S. Krishnan at the "Indian Association for the Cultivation of Science", he discovered that when light traverses a transparent material, some of the deflected light changes wavelength and amplitude. This phenomenon, subsequently known as Raman scattering, results from the Raman effect. His works earned him the 1930 Nobel Prize for Physics and was the first Indian or Asian or non-white person to receive Nobel Prize in any branch of science.


In 1954, the Government of India honoured him with Bharat Ratna, its highest civilian award. February 28 is recognised as the National Science Day in India to commemorate day of the discovery of Raman effect in 1928.

4. A. Crescograph




Sir Jagadish Chandra Bose (Born 30 November 1858 – Mymensingh, Bengal, India (now in Bangladesh) — died November 23, 1937, Giridih, Bihar) was a polymath, physicist, biologist, biophysicist, botanist and archaeologist, and an early writer of science fiction in British India. He pioneered the investigation of radio and microwave optics, made significant contributions to plant science and laid the foundations of experimental science in the Indian subcontinent. “Institute of Electrical and Electronics Engineers” (IEEE), New Jersey, USA named him one of the “Fathers of Radio Science”.


After graduating from St. Xavier's College, Calcutta, Bose went to the University of London, England to study medicine, but could not pursue studies in medicine because of health problems. Instead, he conducted his research with the Nobel Laureate Lord Rayleigh at Cambridge and returned to India. He joined the Presidency College of the University of Calcutta as a Professor of Physics. There, despite racial discrimination and a lack of funding and equipment, Bose carried on his scientific research. He made remarkable progress in his research of remote wireless signaling and was the first to use semiconductor junctions to detect radio signals. However, instead of trying to gain commercial benefit from this invention, Bose made his inventions public in order to allow others to further develop his research.


Bose subsequently made a number of pioneering discoveries in plant physiology. He used his own invention, the “crescograph”, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. His books on plants include “Response in the Living and Non-Living” (1902) and “The Nervous Mechanism of Plants” (1926).


In 1896, Bose wrote “Niruddesher Kahini” (The Story of the Missing One), a short story that was later expanded and added to Abyakta collection in 1921 with the new title “Palatak Tuphan” (Runaway Cyclone). It was one of the first works of Bengali science fiction.




In 2004, Bose was ranked number 7 in BBC's poll of the Greatest Bengali of all time. A crater on the moon has been named in his honour.



5. C. VSNL
