Dr. Subrahmanyan Chandrasekhar, also known as S. Chandrasekhar, was a renowned Indian-American astrophysicist who was awarded the Nobel Prize in Physics in 1983 for his work on the theoretical structure and evolution of stars.
Born in 1910 in Lahore, British India (now Pakistan), Chandrasekhar was the youngest of ten children in a family of scholars. His father was a professor of mathematics and his uncle was a Nobel laureate in literature. Chandrasekhar showed an early interest in science, particularly physics and mathematics, and excelled in his studies.
After completing his undergraduate degree in India, Chandrasekhar went to Cambridge University in England to pursue his PhD in theoretical physics. It was here that he made his most significant contributions to the field, including his work on the structure and evolution of stars.
In the 1930s, Chandrasekhar developed a theory that described the structure and evolution of stars, including their lifespan and eventual fate. His theory, known as the Chandrasekhar limit, stated that when a star's mass exceeds a certain limit (about 1.4 times the mass of the Sun), it collapses under its own gravity and becomes a compact object, such as a white dwarf or a neutron star. This theory was later confirmed through observations of stars and became a fundamental concept in the field of astrophysics.
In addition to his work on the structure and evolution of stars, Chandrasekhar also made significant contributions to the fields of hydrodynamics, radiative transfer, and the study of the structure and evolution of galaxies. He wrote numerous papers and books on these topics and became a leading figure in the field of astrophysics.
Chandrasekhar received numerous awards and accolades for his work, including the Nobel Prize in Physics in 1983, which he shared with William A. Fowler for their work on the synthesis of elements in stars. He was also the recipient of the National Medal of Science, the Copley Medal, and the Royal Medal of the Royal Society, among others.
Dr. S. Chandrasekhar's contributions to the field of astrophysics were groundbreaking and have had a lasting impact on our understanding of the universe. He was a brilliant scientist and a pioneer in his field, and his work continues to be recognized and celebrated today.
Subrahmanyan Chandrasekhar
Their marriage, exceptionally, was by mutual choice rather than by arrangement. Wrote the study of Subrahmanyam Chandrasekhar — Subrahmanyan Chandrasekhar Education Subramaniam completed his initial studies at home. But he pressed on and in 1933, completed his doctorate. Beginning in the 1930s, Subramanyan Chandrasekhar formulated theories for the development that stars subsequently undergo. When these clouds are pulled together by gravitational force, energy is released in the form of heat. Despite the horrific humiliation and sense of betrayal, Chandra soon regretted his reaction, and never lost his high personal regard for Eddington. His exit from the conversation inaugurated a pattern to his research whereby he would enter a field, work for several years before publishing a monograph that became a classic, effectively initiating new questions for research before moving on to other fields.
In childhood, people used to fondly call him Chandra. He was a brilliant student from the very beginning, so later he went to Cambridge University, England, for a scholarship awarded by the Government of India. Pencil in hand, 19-year-old Chandra did some calculations. Chandra's theory was mere mathematical game-playing, Eddington argued, with no basis in reality. The mechanism for the collapse is that the electron shell structure is crushed, so that the star consists of atomic nuclei in an electron gas. Deep insecurities In the face of such opposition, Chandra moved on to other fields. By the time he set out for Cambridge on a government scholarship, he knew enough about the prevailing stellar theory to realise some of its glaring deficiencies.
Eddington was at the peak of his fame as a scientist, philosopher and populiser of the science. It made Eddington a household name and Einstein into an icon of the 20th century. How one may explore the physical content of the general theory of relativity. Neutron stars - objects made entirely of neutrons - and black holes which gobble up anything nearby but do not allow even light to escape, are all now interpreted in terms of Chandrasekhar's famous Critical Mass theory. Chicago: University of Chicago Press. Astrophysics was however, on the fringes of the discipline that was physics. May I now ask you to come forward and receive your prize from the hands of His Majesty the King.
Dr. Subrahmanyan Chandrasekhar, Nobel Prize Winner
Eddington invited Chandra and his wife Lalitha home when they were married in 1936. The famous astronomer Gerard Kuiper, an expert on white dwarfs, immediately pointed out that he had just presented evidence that supported Chandra's theory. In 1964, Chandrasekhar turned the chance to return to the University of Cambridge in a more senior position to stay in Chicago. During this time, he formed friendships with Sir Arthur Eddington and Professor E. Cautious about English journals, he sent this paper to the German Zeitsschrift fur Astrophysik and as fate would have it, Milne was asked to referee.
Chandra was not even given the opportunity to reply. At the time, scientists assumed that when a star burned up the last of its fuel, it would turn into a ball of cinders and go cold - become a white dwarf star. He learned of the job while on a research tour at Harvard. Once, when they met at Trinity, Chandra demanded to know whether if his theory was right it would demolish Eddington's fundamental theory. · Arthur I Miller is the author of Empire of the Stars: Friendship, obsession and betrayal in the quest for black holes, published by Little, Brown. Not even light, emitted from within the black hole, may escape into the outside world, hence the name, black hole. The answer to this deceptively simple question, when he finally unravelled it, was promptly dubbed the Raman Effect and won him the 1930 Nobel Prize for physics.
[Solved] Subrahmanyan Chandrasekhar was awarded Nobel Prize for?
In space we find matter in the most extreme forms; stars at immensely high temperatures and with enormously high densities, and particles and radiation with an energy which we cannot reach, even with our largest accelerators. They belong to different parts of India, with a background as diverse as the country itself. Had Eddington befriended Chandra in order to destroy him? During his time there as a researcher, Chandrasekhar came upon the Chandrasekhar Limit. Fluid flows to Black Holes: A tribute to S Chandrasekhar on his birth centenary. The Chandra X-ray Observatory was launched and deployed by Space Shuttle Columbia on 23 July 1999. He also won a fellowship to continue his work at Cambridge. On January 11 1935, Chandrasekhar presented his discovery to the Royal Astronomical Society.
The Chandra X-ray Observatory was launched and deployed by Space Shuttle Columbia on July 23, 1999. His family had a strong scientific tradition. He was puzzled, but thought no more about it. In 1983, for his pioneering work, Dr. In the same meeting Eddington said that nature would not permit a star to keep on radiating and contracting. The breakthrough came in 1966 at the Livermore National Laboratory in California when scientists began combining the computer codes for astrophysics and hydrogen bombs.
But, what unites them is their passion for science and the impact that their contributions have had on the society. In fact, there is no field in which some or other of his discoveries are not used. This theory is still the basis of our knowledge in this area, and the latest advances in nuclear physics and space research have further shown this theory to be correct. Great progress in the analysis of stellar structure is not possible unless we can answer the following fundamental question: what happens if we go on compressing the matter indefinitely? These scientists are an eclectic mix, who have showcased their talent in fields ranging from biology to nuclear science. Chicago: The University of Chicago Press. Chandrasekhar, known to students, colleagues and friends as Chandra, was born on Oct.
Meanwhile, scientists working to develop the hydrogen bomb began to realise that such a bomb actually mirrored an exploding star. Journal of Astrophysics and Astronomy. William Fowler of the California Institute of Technology, who was honored for his study of how the elements were formed. There he carried out vital work first in radiative transfer the study of how radiation moves through matter , then in hydrodynamic and hydromagnetic stabilities the study of flow. He was also the nephew of Prof. .
He has been a rebel since his early days. Triumphantly he sat down, assuming that Eddington would support his conclusions. The collapse, in its turn, triggers thermonuclear explosions inside them, and the ensuing energy counteracts the gravitational pull, creating a state of equilibrium - till the nuclear furnace uses up all fuel available in the star's core. In his later years, Chandrasekhar devoted himself to exploring the common ground between artistic creation and scientific discovery. The same year he was awarded the Bruce Medal of the Astronomical Society of the Pacific. The daily reminders that India was under the yoke of the British Empire rankled him and science seemed a way to show that he was at least equal to the colonial masters. And it was these ideas that were whirling about in his mind as he gazed at the stars during his voyage to England.
