Subramaniam Chandrasekhar (1910-1995) :::::Nephew of Sir C. V.Raman :::


He obtained his doctorate in 1933. Soon after receiving his doctorate,Chandrasekhar was awarded the Prize Fellowship at Trinity College,Cambridge. In 1937, he accepted the position of Research Associate at theUniversity of Chicago. Chandrasekhar stayed at University of Chicagothroughout his career, becoming the Morton D. Hall Distinguished ServiceProfessor in Astronomy and Astrophysics in 1952. In 1952 he established theAstrophysical Journal and was its editor for 19 years, transforming it from alocal publication of the University of Chicago into the national journal of theAmerican Astronomical Society. He became a US citizen in 1958.

He was elected Fellow of the Royal Society of London and in 1962received the Society’s Royal Medal. He also received the US National Medalof Science (1966). [color=#ff8c00][size=7][b]He was awarded the Nobel prize for Physics in 1983 forhis theoretical work on the physical processes of importance to the structureof stars and their evolution. Chandra was a popular teacher who guided overfifty students to their Ph.D.s including some who went on to win the Nobelprize themselves!![/b][/size][/color] His research explored nearly all branches of theoreticalastrophysics and he published ten books, each covering a different topic,including one on the relationship between art and science.

These are The Real People Who made the Change to Our Country and we need to praise them for alll their Vision to the Current Generations...



Vikram Sarabhai pioneered India’s space age by expanding the Indian SpaceResearch Organization[size=5][color=#ff0000][b]. India’s first satellite Aryabhata launched in 1975, wasone of the many projects planned by him. [/b][/color][/size]

Like Bhabha, Sarabhai wanted thepractical application of science to reach the common man.[size=5][color=#ff0000][b] Thus he saw agolden opportunity to harness space science to the development of the countryin the fields of communication, meteorology, remote sensing and education.[/b][/color][/size]

The [color=#ff8c00][size=5][b]Satellite Instructional Television Experiment (SITE) launched in 1975-76, brought education to five million people in 2,400 Indian villages. [/b][/size][/color]In 1965,he established the Community Science Centre in Ahmedabad with a view to popularise science among children. His deep cultural interests led him, alongwith his wife Mrinalini Sarabhai, to establish Darpana Academy, an institutiondevoted to performing arts and propagation of ancient culture of India.

Dr. Har Gobind Khorana [size=5][color=#ff0000][b]shared the Nobel Prize for Medicine and Physiology in 1968 with Marshall Nirenberg and Robert Holley for cracking the genetic code[/b][/color][/size]. They established that this code, [b]the biological language common to all living organisms,[/b] is spelled out in three-letter words: each setof three nucleotides codes for a specific amino acid. Dr. Khorana was also thefirst to synthesize oligonucleotides (strings of nucleotides). Today,oligonucleotides are indispensable tools in biotechnology, widely used inbiology labs for sequencing, cloning and genetic engineering.

G. N. Ramachandran (1922-2001)
G. N. Ramachandran was born on 8 October 1922 in Ernakulam, Kerala.His father G. Narayana Iyer was the principal of Maharaja’s college inErnakulam. Ramachandran did his intermediate from Maharaja’s college andhis B.Sc. (Hons) in Physics from St. Joseph’s College, Tiruchi. In 1942 he joined the Indian Institute of Science (IISc), Bangalore as a student in theElectrical Engineering department.

However, under the influence of C.V.Raman, he shifted to Physics. He obtained his M.Sc. and then his Ph.D. in1947, under Raman’s supervision. He then went to the Cavendish Laboratory,Cambridge and obtained his second Ph.D degree under Prof. Wooster.He returned to India in 1949 and joined IISc as an Assistant Professor.In 1952, at the young age of 30, he moved to Madras as the Head of thePhysics Department at the University of Madras.

On the suggestion of J.D.Bernal, the crystallographer and chemist, who visited the University in 1952,[color=#8b4513][b]he started work on determining the structure of the protein collagen, the fibrousprotein found in skin, bone and tendon. Based on the limited data available atthe time, in 1954, he proposed, along with Gopinath Kartha, the triple-helixstructure for collagen, [/b][/color]later revised in the light of new data to the coiled coilstructure for biomolecules. This was a fundamental advance in theunderstanding of biomolecular structures.

He and his colleagues C.Ramakrishnan and V. Sasisekharan went on to develop methods to examineand assess structures of biomolecules, in particular peptides. In 1963, this resulted in the famous Ramachandran map, which is an indispensable tool inthe study of molecular structures today. His contributions in the field of X-raycrystallography such as anomalous dispersion, new kinds of Fourier syntheses,and [color=#000080][b]X-ray intensity statistics are also extremely important. His 1971 paper with A.V. Lakshminarayanan on three-dimensional image reconstruction was to have important applications in Computer Assisted Tomography.[/b][/color] (The 1979 Nobel Prize in Physiology or Medicine was awarded to A.M. Cormack and Sir G.N. Hounsfield for their work in CAT).
