Stephen Hawking

Professor Stephen William Hawking was born on 8th January 1942 (exactly 300 years after the death of Galileo) in Oxford, England. His parents' house was in north London but during the second world war Oxford was considered a safer place to have babies. When he was eight his family moved to St. Albans, a town about 20 miles north of London. At the age of eleven, Stephen went to St. Albans School and then on to University College, Oxford (1952); his father's old college. Stephen wanted to study mathematics although his father would have preferred medicine. Mathematics was not available at University College, so he pursued physics instead. After three years and not very much work, he was awarded a first class honours degree in natural science.He is a very influential scientist. His books have captured the minds of millions. His theories have baffled the minds of great thinkers. His discoveries break the laws of which we thought governed the universe. He is a man whose work has changed the ways we look at the universe, our galaxy, our solar-system, and our planet. His name is Stephen Hawking. He has written many books, attended two universities, and is a renowned scientist. From conception to the present, Stephen Hawking has lived a very interesting life.

Periodic table

Periodic table ELEMENTS- Elements are pure from of matter that are made up of one type of atom. · DOBEREINER- Grouped all elements in three (triads). · NEWLAND- Observed that when elements are arranging in increasing order of their atomic mass. Every eighteen element beginning from any element resemble the first element in its physical and chemical properties. · DMITRI MENDLEVE- He is a Russian chemist gave the first periodic table of elements based on his law which states that “The properties of elements are the periodic functions of their atomic mass.” · Modern periodic table was given by HENERY MOSELEY. Periodic table- A tabular form of elements in group and periods highlighting the regular trends in...

Ammonium phosphate

Ammonium phosphate Ammonium phosphate is an ammonium salt of orthophosphoric acid. It is a highly unstable compound with the formula (NH 4 ) 3 PO 4 . Because of its instability, it is elusive and of no commercial value. A related "double salt", (NH 4 ) 3 PO 4 . (NH 4 ) 2 HPO 4 is also recognized but is too unstable for practical use. Both triammonium salts evolve ammonia. In contrast to the unstable nature of the triammonium salts, the diammonium phosphate (NH 4 ) 2 HPO 4 monoammonium salt (NH 4 )H 2 PO 4, are stable materials that are commonly used as fertilizers to provide plants with fixed nitrogen and phosphorus. PREPARATION OH AMMONIUM TRIPHOSPHATE Triammonium phosphate can be prepared in the laboratory by treating 85% phosphoric acid with 30% ammonia solution: ...

Himalaya

Himalaya The Himalayas constitutes an imposing crescent-shaped mountain range extending for over 2500 km from the south of the Indus Valley beyond Nanga Parbat in the west to Namcha Barwa in the east . The range varies in width from 350 km in the west to 150 km in the east. The majestic mountain chain showing prominent southward convexity stands like a wall bordering the entire northern margin of the Indian Subcontinent. Himalayas, Nepali Himalaya, great mountain system of Asia forming a barrier between th Plateau of tibet to the north and the alluvial plains of the Indian subcontinent to the south. The Himalayas include the highest mountains in the world, with more than 110 peaks rising to elevations of 24,000 feet (7,300 metres) or more above sea level. One of those peaks is Mount Everest (Tibetan: Chomolungma; Chinese: Qomolangma Feng; Nepali: Sagarmatha), the world’s highes...
