Aswan Low Dam
The Aswan Low Dam or Old Aswan Dam is a gravity masonry buttress dam on the Nile River in Aswan, Egypt. The dam was built at the former first cataract of the Nile, and is located about 1000 km up-river and 690 km (direct distance) south-southeast of Cairo. When initially constructed between 1899 and 1902, nothing of its scale had ever been attempted; on completion, it was the largest masonry dam in the world. The dam was designed to provide storage of annual floodwater and augment dry season flows to support greater irrigation development and population growth in the lower Nile. The dam, originally limited in height by conservation concerns, worked as designed, but provided inadequate storage capacity for planned development and was raised twice, between 1907 and 1912 and again in 1929–1933. These heightenings still did not meet irrigation demands and in 1946 it was nearly over-topped in an effort to maximize pool elevation. This led to the investigation and constructio ...

Science (journal)
''Science'', also widely referred to as ''Science Magazine'', is the peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS) and one of the world's top academic journals. It was first published in 1880, is currently circulated weekly and has a subscriber base of around 130,000. Because institutional subscriptions and online access serve a larger audience, its estimated readership is over 400,000 people. ''Science'' is based in Washington, D.C., United States, with a second office in Cambridge, UK. Contents The major focus of the journal is publishing important original scientific research and research reviews, but ''Science'' also publishes science-related news, opinions on science policy and other matters of interest to scientists and others who are concerned with the wide implications of science and technology. Unlike most scientific journals, which focus on a specific field, ''Science'' and its rival ''Nature (journal), Nature'' c ...

Jewish Encyclopedia
''The Jewish Encyclopedia: A Descriptive Record of the History, Religion, Literature, and Customs of the Jewish People from the Earliest Times to the Present Day'' is an English-language encyclopedia containing over 15,000 articles on the history, culture, and state of Judaism up to the early 20th century. The encyclopedia's managing editor was Isidore Singer and the editorial board was chaired by Isaac K. Funk and Frank H. Vizetelly. The work's scholarship is still highly regarded. The American Jewish Archives deemed it "the most monumental Jewish scientific work of modern times", and Rabbi Joshua L. Segal said "for events prior to 1900, it is considered to offer a level of scholarship superior to either of the more recent Jewish encyclopedias written in English." It was originally published in 12 volumes between 1901 and 1906 by Funk & Wagnalls of New York, and reprinted in the 1960s by KTAV Publishing House. It is now in the public domain. History Concep ...

A History Of Our Time
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Battle Of Tel El-Kebir
The Battle of Tel El Kebir (often spelled Tel-El-Kebir) was fought on 13 September 1882 at Tell El Kebir in Egypt, 110 km north-north-east of Cairo. An entrenched Egyptian force under the command of Ahmed ʻUrabi was defeated by a British army led by Garnet Wolseley, in a sudden assault preceded by a march under cover of darkness. The battle was the decisive engagement of the Anglo-Egyptian War. Background Bombardment and invasion of Alexandria On May 20, 1882, a combined Franco–British fleet arrived at Alexandria. At the same time, Egyptian troops were reinforcing the coastal defenses of the city in anticipation of an attack. These events heightened tension in Alexandria, and eventually triggered tumultuous rioting with loss of life on both sides. As a result of the riots, an ultimatum was sent to the Egyptian government demanding they order Urabi's officers in Alexandria to dismantle their coastal defence batteries. The Egyptian government refused. Meanwhile, ten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Book Of Optics
The ''Book of Optics'' ( ar, كتاب المناظر, Kitāb al-Manāẓir; la, De Aspectibus or ''Perspectiva''; it, Deli Aspecti) is a seven-volume treatise on optics and other fields of study composed by the medieval Arab scholar Ibn al-Haytham, known in the West as Alhazen or Alhacen (965–c. 1040 AD). The ''Book of Optics'' presented experimentally founded arguments against the widely held extramission theory of vision (as held by Euclid in his ''Optica''), and proposed the modern intromission theory, the now accepted model that vision takes place by light entering the eye.D. C. Lindberg (1976), ''Theories of Vision from al-Kindi to Kepler'', Chicago, Univ. of Chicago Press The book is also noted for its early use of the scientific method, its description of the camera obscura, and its formulation of Alhazen's problem. The book extensively affected the development of optics, physics and mathematics in Europe between the 13th and 17th centuries. Vision theory B ...
