Scientists



The eminent scientist who ushered India into the atomic age was Dr. Homi Jehangir Bhabha. He was born on 30 October 1909 in a Parsi family of Mumbai. He is called the 'Father of Indian Nuclear Science'. Dr.Bhabha was appointed the first chairman of the Atomic Energy Commission, set up in 1948. It was largely due to his efforts that the nation's first Atomic research Center, now named Bhabha Atomic research Center, was established at Trombay, near Mumbai. Under his expert guidance the nation's first atomic reactor 'Apsara' was also commissioned in 1956. In 1945, he founded the Tata Institute of Fundamental Research in Mumbai. Dr.Bhabha had a highly distinguished career and was an exceptionally bright student. Even as a student, he made some fundamental discoveries in electricity, magnetism, quantum theory and the cosmic rays. Dr.Bhabha as the scientist of a very high caliber, received many national and international awards and honours. In 1942, he was awarded the 'Adams' award. In 1951, Bhabha was elected the president of the Indian Science Congress. In 1955, he was elected the chairman of the U.N. sponsored International conference on the peaceful uses of the atomic energy held in Geneva. The Government of India also honoured him with 'Padma Bhushan' in 1954. The 'Homi Jehangir Bhabha Award' has been instituted by Indian National Science Academy. He passed away in 1966 in a plane crash.

 

C.V.Raman was a scientist in Physics, who won noble prize in 1930. Raman was born on 7th November,1888 at Ayyanpettai in Tamil Nadu. He had his education in Visakhapatanam and Madras. After getting top ranking in the Financial Civil Service Competitive Exam, he was appointed as Deputy Accountant General in Calcutta (Kolkutta). In 1917 he became the professor of Physics at the Calcutta University. After 15 years service at the Calcutta University, Raman shifted to Bangalore and became the Director of the Indian Institute of Science in 1933. In 1943 he founded 'Raman Research Institute', near Bangalore. His discovery of the 'Raman Effect' made a very distinctive contribution to Physics. He was knighted by the British Government in 1929. He was also conferred the highest title of 'Bharat Ratna' in 1954. The 'Raman Effect' was a demonstration of the 'Collision' effect of light bullets (photons) passing through a transparent medium, whether solid, liquid or gaseous. Raman's publications include 'Molecular Diffraction of Light', 'Mechanical Theory of Bowed Strings' and 'Diffraction of X-ray's', 'Theories of Musical Instruments' etc. Raman conducted pioneering research in musical acoustics, particularly on Tamboura, the well known Indian musical instrument.


Jagdish Chandra Bose was an Indian physicist who pioneered the investigation of radio and microwave optics. Bose was born in Mymensingh in Bengal (now in Bangladesh) on November 30, 1858. His father, Bhagawan Chandra Bose worked as a tax collector for the British East India Company. His family originally hailed from the village Rarikhal, Bikrampur, in the current day Dhaka District of Bangladesh. Having started his studies in a local school, Bose studied at the St. Xavier's School and College at Kolkata. He passed the Entrance examination (equivalent to school graduation) of Calcutta University in 1875. He received a B.A. in Science from Calcutta University in 1879. Next, Bose went to England to study at Christ's College, Cambridge. He received a B.A. from Cambridge University and a B.Sc. from the London University in 1884. After completing his studies in London, Bose return to Kolkatta and was appointed Professor at Presidency College in Kolkatta. Then he became the director of the institute he founded and remained in the post till his death on 23rd November 1937. Jagadish Chandra Bose was one of the pioneers of modern science in India.His researchwas on the properties of electro-magnetic waves.



 Srinivasa Ramanujan was a great Mathematician, who became world famous at the age of twenty six. He was born at Erode in Tamil Nadu on 22 December 1887. Ramanujan could not complete his college education because of illness. He was so interested in mathematics that he learned on his own. He found out new formulas for solving mathematical problems and wrote articles about them. Professor Hardy a scientist in the Cambridge University saw one his article and impressed by his knowledge, took Ramanujan to England. Ramanujan was considered as the master of theory of numbers. The most outstanding of his contributions was his formula for p (n), the number of 'partitions' of 'n'. It was in 1914, while he was working in Trinity College he developed the 'Number Theory' and for his valuable contribution, was elected fellow of Trinity College on 18th October 1917. He returned to India in 1919 and began Research. He passed away on 26 April 1920. Government of India issued a commemorative stamp in his honour. Indian National Science academy and many other scientific institutions in India are giving various awards in memory of this brilliant mathematician. 


   
Vikram.A.Sarabhai, was the main personality behind the launching of India's first satellite, Aryabhata in 1975. He was born in Ahmedabad, Gujarat in a family of industrialists. He was also responsible for the Equatorial Rocket Building Station at Thumba. Sarabhai set up the Ahmedabad Textile Industries Research Association, a laboratory for research in Physics and the Indian Institute of Management. Sarabhai was the second chairman of India's Atomic Energy Commission and the Indian Space Research Organisation. Sarabhai's study of cosmic rays under the eminent scientist Dr. C.V. Raman, revealed that cosmic rays are a stream of energy particles reaching the earth from the outer space, being influenced on their way by the sun, the atmosphere and magnetism. This study helps in observing terrestrial magnetism and the atmosphere, the nature of the sun and outer space. He was conferred 'Padma Shri' in 1966 and was posthumously awarded 'Padma Vibushan' in 1972. He was also awarded 'Dr. Shanti Swarup Bhatnagar Prize' in 1962. This great scientist could be credited with launching India into space age.
