WHAT IS
If someone ask that how fast or slow a car is moving , actually he is asking about the speed of the car.
To know rate of motion we use the term "speed"
To know rate of motion we use the term "speed"
In the above diagram a car is moving and if you want know the speed of the car , you just want to know that how fast it is moving.
speed= distance/time

pronunciation (help·info) (Marathi: किसन बाबुराव हजारे, Kisan Bāburāv Hajārē ?) (born 15 June 1937), popularly known as Anna Hazare pronunciation (help·info) (Marathi: अण्णा हजारे, Aṇṇā Hajārē ?; is an Indian social activist who is recognised for his participation in the 2011 Indian anti-corruption movement, using nonviolent methods following the teachings of Mahatma Gandhi.[1][2] Hazare also contributed to the development and structuring of Ralegan Siddhi, a village in Parner taluka of Ahmednagar district, Maharashtra, India. He was awarded the Padma Bhushan, the third-highest civilian award—by the Government of India in 1992 for his efforts in establishing this village as a model for others.[3]Anna Hazare started a hunger strike on 5 April 2011 to exert pressure on the Indian government to enact a strict anti-corruption law as envisaged in the Jan Lokpal Bill, for the institution of an ombudsman with the power to deal with corruption in public offices. The fast led to nation-wide protests in support of Hazare. The fast ended on 9 April 2011, the day after the government accepted Hazare's demands. The government issued a gazette notification on the formation of a joint committee, constituted of government and civil society representatives, to draft the legislation.[4][5]
Anna has been featured as the most influential person in Mumbai by a national daily newspaper.[6] He has faced criticism for his authoritarian views on justice, including death as punishment for corrupt public officials and his alleged support for forced vasectomies as a method of family planning.[7][8]

Stephen Hawking
Stephen William Hawking, CH, CBE, FRS, FRSA (born 8 January 1942)[1] is an English theoretical physicist and cosmologist, whose scientific books and public appearances have made him an academic celebrity. He is an Honorary Fellow of the Royal Society of Arts,[2] a lifetime member of the Pontifical Academy of Sciences,[3] and in 2009 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States.[4]
Hawking was the Lucasian Professor of Mathematics at the University of Cambridge for 30 years, taking up the post in 1979 and retiring on 1 October 2009.[5][6] He is now Director of Research at the Centre for Theoretical Cosmology in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge. He is also a Fellow of Gonville and Caius College, Cambridge and a Distinguished Research Chair at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario.[7] He is known for his contributions to the fields of cosmology and quantum gravity, especially in the context of black holes. He has also achieved success with works of popular science in which he discusses his own theories and cosmology in general; these include the runaway best seller A Brief History of Time, which stayed on the British Sunday Times best-sellers list for a record-breaking 237 weeks.[8][9]
Hawking's key scientific works to date have included providing, with Roger Penrose, theorems regarding gravitational singularities in the framework of general relativity, and the theoretical prediction that black holes should emit radiation, which is today known as Hawking radiation (or sometimes as Bekenstein–Hawking radiation).[10]
Hawking has a motor neurone disease that is related to amyotrophic lateral sclerosis, a condition that has progressed over the years and has left him almost completely paralysed.

/ˈælbərt ˈaɪnstaɪn/;German: [ˈalbɐt ˈaɪnʃtaɪn] (
listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics and one of the most prolific intellects in human history.[2][3] 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".[4] The latter was pivotal in establishing quantum theory within physics.Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.[5]
He was visiting the United States when Adolf Hitler came to power in 1933, and did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the U.S., becoming a citizen in 1940. On the eve of World War II, he helped alert President Franklin D. Roosevelt that Germany might be developing an atomic weapon, and recommended that the U.S. begin similar research; this eventually led to what would become the Manhattan Project. Einstein was in support of defending the Allied forces, but largely denounced using the new discovery of nuclear fission as a weapon. Later, together with Bertrand Russell, Einstein signed the Russell–Einstein Manifesto, which highlighted the danger of nuclear weapons. Einstein taught physics at the Institute for Advanced Study at Princeton, New Jersey, until his death in 1955.
Einstein published more than 300 scientific papers along with over 150 non-scientific works.[5][6] His great intelligence and originality have made the word "Einstein" synonymous with genius.[7]

Isaac NewtonFrom Wikipedia, the free encyclopedia (Redirected from Isac Newton)
His monograph Philosophiæ Naturalis Principia Mathematica, published in 1687, lays the foundations for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion, which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws, by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the Scientific Revolution. The Principia is generally considered to be one of the most important scientific books ever written. Widely regarded as one of the most influential people in human history, Newton built the first practical reflecting telescope[7] and developed a theory of colour based on the observation that a prism decomposes white light into the many colours that form the visible spectrum. He also formulated an empirical law of cooling and studied the speed of sound. In mathematics, Newton shares the credit with Gottfried Leibniz for the development of differential and integral calculus. He also demonstrated the generalised binomial theorem, developed Newton's method for approximating the roots of a function, and contributed to the study of power series. | |||||||||||||||||||||||||||||||||
