Abhay Ashtekar
Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist. He is the Eberly Professor of Physics and the Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University. As the creator of Ashtekar variables, he is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. He has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists. In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a legendary 1974 prediction by Hawking. Oxford mathematical physicist Roger Penrose has described Ashtekar's approach to quantum gravity as "The most important of all the attempts at 'quantizing' general relativity." Ashtekar was elected as Member to National Academy of Sciences in May 2016. Biography Abhay Ashtekar grew up in several cities, including Mumbai, in the state of Maharashtra, India.

Kolhapur, Maharashtra
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 for h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

He is also currently a Distinguished Visiting Research Chair at the Perimeter Institute, and core member of the Rotman Institute of Philosophy of the Western University. He works mainly in the field of quantum gravity and is a founder of loop quantum gravity theory. He has also worked in the history and philosophy of science. He collaborates with several Italian newspapers, including the cultural supplements of the ''Corriere della Sera'', '' Il Sole 24 Ore'' and ''La Repubblica''.

Big Bounce
The Big Bounce is a hypothesized cosmological model for the origin of the known universe. It was originally suggested as a phase of the ''cyclic model'' or ''oscillatory universe'' interpretation of the Big Bang, where the first cosmological event was the result of the collapse of a previous universe. It receded from serious consideration in the early 1980s after inflation theory emerged as a solution to the horizon problem, which had arisen from advances in observations revealing the large-scale structure of the universe. In the early 2000s, inflation was found by some theorists to be problematic and unfalsifiable in that its various parameters could be adjusted to fit any observations, so that the properties of the observable universe are a matter of chance. Alternative pictures including a Big Bounce may provide a predictive and falsifiable possible solution to the horizon problem, and are under active investigation as of 2017.

Andrzej Trautman
Andrzej Mariusz Trautman (born January 4, 1933 in Warsaw) is a Polish mathematical physicist who has made contributions to classical gravitation in general and to general relativity in particular. He made contributions to gravitation as early as 1958. The "Trautman-Bondi mass" is named after him. Biography Trautman was born in Warsaw, Poland into an artistic family. His father, Mieczysław, was a painter and taught drawing at a secondary school in Warsaw. His mother, Eliza Trautman (née André), was French, though she was born in Spain, where her father, Marius André, was working as a French consular officer. His schooling, at the elementary level, was interrupted by the Warsaw Uprising of 1944. After spending about ten months in Germany, he returned, with his mother (his father had died in 1941) to Poland. In the fall of 1945, they both went to Paris, to stay with their family there. In France, Trautman attended a Polish secondary school from which he graduated in 1949 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bhagavad Gita
The Bhagavad Gita (; sa, श्रीमद्भगवद्गीता, lit=The Song by God, translit=śrīmadbhagavadgītā;), often referred to as the Gita (), is a 700- verse Hindu scripture that is part of the epic ''Mahabharata'' (chapters 23–40 of book 6 of the Mahabharata called the Bhishma Parva), dated to the second half of the first millennium BCE and is typical of the Hindu synthesis. It is considered to be one of the holy scriptures for Hinduism. The Gita is set in a narrative framework of a dialogue between Pandava prince Arjuna and his guide and charioteer Krishna. At the start of the dharma yuddha (or the "righteous war") between the Pandavas and the Kauravas, Arjuna is preoccupied by a moral and emotional dilemma and despairs about the violence and death the war will cause in the battle against his kin. Wondering if he should renounce the war, he seeks Krishna's counsel, whose answers and discourse constitute the Gita. Krishna counsels Arjuna to "fu ...

Atheist
Atheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists. The first individuals to identify themselves as atheists lived in the 18th century during the Age of Enlightenment. The French Revolution, noted for its "unprecedented atheism", witnessed the first significant political movement in history to advocate for the supremacy of human reason.Extract of page 22 In 1967, Albania declared itself the first official atheist cou ...

Oxford University
Oxford () is a city in England. It is the county town and only city of Oxfordshire. In 2020, its population was estimated at 151,584. It is north-west of London, south-east of Birmingham and north-east of Bristol.

Oxford's industries include motor manufacturing, education, publishing, information technology and science. History The history of Oxford in England dates back to its original settlement in the Saxon period. Originally of strategic significance due to its controlling location on the upper reaches of the River Thames at its junction with the River Cherwell, the town grew in national importance during the early Norman period, and in the late 12th century became home to the fledgling University of Oxford. The city was besieged during The Anarchy in 1142. The university rose to domina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
