Ibn Khaldun. Biography Ibn Khaldun's life is relatively well-documented, as he wrote an autobiography (التعريف بابن خلدون ورحلته غربا وشرقا, at-Taʻrīf bi-ibn Khaldūn wa-Riḥlatih Gharban wa-Sharqan) in which numerous documents regarding his life are quoted word-for-word.
Generally known as "Ibn Khaldūn" after a remote ancestor, he was born in Tunis in AD 1332 (732 A.H.) into an upper-class Andalusian family of Arab descent, the Banu Khaldun. George Eliot. "Mary Ann Evans" redirects here.
For the wife of Benjamin Disraeli, see Mary Anne Disraeli. She used a male pen name, she said, to ensure her works would be taken seriously. Female authors were published under their own names during Eliot's life, but she wanted to escape the stereotype of women only writing lighthearted romances. She also wished to have her fiction judged separately from her already extensive and widely known work as an editor and critic. An additional factor in her use of a pen name may have been a desire to shield her private life from public scrutiny and to prevent scandals attending her relationship with the married George Henry Lewes, with whom she lived for over 20 years. Her 1872 work Middlemarch has been described by Martin Amis and Julian Barnes as the greatest novel in the English language.

Frankfurt School. History The Institute for Social Research The term "Frankfurt School" arose informally to describe the thinkers affiliated or merely associated with the Frankfurt Institute for Social Research; it is not the title of any specific position or institution per se, and few of these theorists used the term themselves.
The Institute for Social Research (Institut für Sozialforschung) was founded in 1923 by Carl Grünberg, a Marxist legal and political professor at the University of Vienna, as an adjunct of the University of Frankfurt; it was the first Marxist-oriented research center affiliated with a major German university. However, the school can trace its earliest roots back to Felix Weil, who used money from his father's grain business to finance the Institut.
Weil (1898-1975), a young Marxist, had written his doctoral thesis (published by Karl Korsch) on the practical problems of implementing socialism. Indian Rebellion of 1857. Other regions of Company-controlled India, such as Bengal, the Bombay Presidency, and the Madras Presidency, remained largely calm. In Punjab, the Sikh princes backed the Company by providing soldiers and support. The large princely states of Hyderabad, Mysore, Travancore, and Kashmir, as well as the smaller ones of Rajputana, did not join the rebellion. In some regions, such as Oudh, the rebellion took on the attributes of a patriotic revolt against European presence. Maratha leaders, such as Lakshmibai, the Rani of Jhansi, became folk heroes in the nationalist movement in India half a century later.
Apollonius of Perga. Conics Parabola connection with areas of a square and a rectangle, that inspired Apollonius of Perga to give the parabola its current name.
The degree of originality of the Conics (Κωνικά) can best be judged from Apollonius's own prefaces. Books i–iv he describes as an "elementary introduction" containing essential principles, while the other books are specialized investigations in particular directions. He then claims that, in Books i–iv, he only works out the generation of the curves and their fundamental properties presented in Book i more fully and generally than did earlier treatises, and that a number of theorems in Book iii and the greater part of Book iv are new. Allusions to predecessor's works, such as Euclid's four Books on Conics, show a debt not only to Euclid but also to Conon and Nicoteles. InOurTime 20130523. Mars. On 28 September 2015, NASA announced the presence of briny flowing salt water on the Martian surface. It is theorized by some scientists that life on Earth may have begun on Mars and was ferried to Earth via a Martian derived asteroid, due to the lack of certain adequate conditions present on Earth when life is believed to have evolved.  Mars can easily be seen from Earth with the naked eye, as can its reddish coloring.
Its apparent magnitude reaches −2.91, which is surpassed only by Jupiter, Venus, the Moon, and the Sun. Optical ground-based telescopes are typically limited to resolving features about 300 kilometers (190 mi) across when Earth and Mars are closest because of Earth's atmosphere.
