Jayant V. Narlikar
Jayant Vishnu Narlikar (born 19 July 1938) is an Indian astrophysicist and emeritus professor at the Inter-University Centre for Astronomy and Astrophysics (IUCAA). He developed with Sir Fred Hoyle the conformal gravity theory, known as Hoyle–Narlikar theory. It synthesises Albert Einstein's theory of relativity and Mach's principle. It proposes that the inertial mass of a particle is a function of the masses of all other particles, multiplied by a coupling constant, which is a function of cosmic epoch. Early life Narlikar was born in Kolhapur, India on 19 July 1938 in a family of scholars. His father, Vishnu Vasudev Narlikar, was a mathematician and theoretical physicist who served as Professor and Head of Department of Mathematics at Banaras Hindu University, Varanasi, and mother, Sumati Narlikar, was a scholar of Sanskrit. His wife is Mangala Narlikar and he has three daughters. His maternal uncle was the distinguished statistician V. S. Huzurbazar. Career Narlikar comp ...

Kolhapur
Kolhapur () is a city on the banks of the Panchganga River in the southern part of the Indian state of Maharashtra. It is the administrative headquarter of the Kolhapur district. In, around 2 C.E. Kolapur's name was 'Kuntal'. Kolhapur is known as ''`Dakshin Kashi''' or Kashi of the South because of its spiritual history and the antiquity of its shrine Mahalaxmi, better known as Ambabai. The region is known for the production of the famous hand-crafted and braided leather slippers called Kolhapuri chappal, which received the Geographical Indication designation in 2019. In Hindu mythology, the city is referred to as "''Karvir''." Before India became independent in 1947, Kolhapur was a princely state under the Bhosale Chhatrapati of the Maratha Empire. It is an important center for the Marathi film industry. Etymology Kolhapur is named after Kolhasur, a demon in Hindu History. According to History, the demon Kolhasur renounced asceticism after his sons were killed by God f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Padma Vibhushan
The Padma Vibhushan ("Lotus Decoration") is the second-highest Indian honours system, civilian award of the Republic of India, after the Bharat Ratna. Instituted on 2 January 1954, the award is given for "exceptional and distinguished service". All persons without distinction of race, occupation, position or sex are eligible for these awards.

Fitzwilliam College
Fitzwilliam College is a constituent college of the University of Cambridge. The college traces its origins back to 1869 and the foundation of the Non-Collegiate Students Board, a venture intended to offer academically excellent students of all backgrounds a chance to study at the university. The institution was originally based at Fitzwilliam Hall (later renamed Fitzwilliam House), opposite the Fitzwilliam Museum in south-west Cambridge. Having moved to its present site in the north of the city, Fitzwilliam attained collegiate status in 1966. Female undergraduates were first admitted in 1978, around the time most colleges were first admitting women. Fitzwilliam is now home to around 475 undergraduates, 500 graduate students and 90 fellows. By overall student numbers, it is the seventh-largest college in Cambridge as of 2018/19. Notable alumni of Fitzwilliam College include six Nobel Laureates, a large number of prominent academics, public officials, businesspeople, clergy and ...

Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxford a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanskrit
Sanskrit (; attributively , ; nominally , , ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rig Veda, a colle ...

Mach's Principle
In theoretical physics, particularly in discussions of gravitation theories, Mach's principle (or Mach's conjecture) is the name given by Einstein to an imprecise hypothesis often credited to the physicist and philosopher Ernst Mach. The hypothesis attempted to explain how rotating objects, such as gyroscopes and spinning celestial bodies, maintain a frame of reference. The proposition is that the existence of absolute rotation (the distinction of local inertial frames vs. rotating reference frames) is determined by the large-scale distribution of matter, as exemplified by this anecdote: You are standing in a field looking at the stars. Your arms are resting freely at your side, and you see that the distant stars are not moving. Now start spinning. The stars are whirling around you and your arms are pulled away from your body. Why should your arms be pulled away when the stars are whirling? Why should they be dangling freely when the stars don't move? Mach's principle says th ...

Theory Of Relativity
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to the forces of nature. It applies to the cosmological and astrophysical realm, including astronomy. The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old Classical mechanics, theory of mechanics created primarily by Isaac Newton. It introduced concepts including 4-dimensional spacetime as a unified entity of space and time in physics, time, relativity of simultaneity, kinematics, kinematic and gravity, gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in ...

Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Conformal Gravity
Conformal gravity refers to gravity theories that are invariant under conformal transformations in the Riemannian geometry sense; more accurately, they are invariant under Weyl transformations g_\rightarrow\Omega^2(x)g_ where g_ is the metric tensor and \Omega(x) is a function on spacetime. Weyl-squared theories The simplest theory in this category has the square of the Weyl tensor as the Lagrangian :\mathcal=\int \, \mathrm^4x \, \sqrt \, C_\,C^~, where \; C_ \; is the Weyl tensor. This is to be contrasted with the usual Einstein–Hilbert action where the Lagrangian is just the Ricci scalar. The equation of motion upon varying the metric is called the Bach tensor, :2\,\partial_a\,\partial_d\,^d ~~+~~ R_ \, ^d ~=~ 0~, where \; R_ \; is the Ricci tensor. Conformally flat metrics are solutions of this equation. Since these theories lead to fourth-order equations for the fluctuations around a fixed background, they are not manifestly unitary. It has therefore been generally be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inter-University Centre For Astronomy And Astrophysics
The Inter-University Centre for Astronomy and Astrophysics (IUCAA) is an autonomous institution set up by the University Grants Commission of India to promote nucleation and growth of active groups in astronomy and astrophysics in Indian universities. IUCAA is located in the University of Pune campus next to the National Centre for Radio Astrophysics, which operates the Giant Metrewave Radio Telescope. IUCAA has a campus designed by Indian architect Charles Correa. History After the founding of the Giant Metrewave Radio Telescope (GMRT) by Prof. Govind Swarup, a common research facility for astronomy and astrophysics was proposed by Dr. Yash Pal of the planning commission. Working on this idea, astrophysicist Prof. Jayant Narlikar, along with Ajit Kembhavi and Naresh Dadhich set up IUCAA within the Pune University campus in 1988. In 2002, IUCAA initiated a nationwide campaign to popularize astronomy and astrophysics in colleges and universities. IUCAA arranged visitor progra ...

Emeritus Professor
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Protoc ...
