Geschichte der Mathematik Teil 2 Mathematik im alexandrinischen Zeitalter Arabische und indische Mathematik Mathematik zur Zeit der Renaissance 17. Jahrhundert Während des 17.Jahrhunderts wurden in der Mathematik die großen Fortschritte erzielt. Das Jahrhundert begann mit der Entdeckung der Logarithmen durch den schottischen Mathematiker John Napier. Der fortwährende Nutzen soll den französischen Astronomen Pierre Simon Laplace fast zwei Jahrhunderte später zu der Bemerkung verleitet haben, Napier hätte versucht, durch Halbieren der Mühen der Astronomen ihre Lebenszeit zu verdoppeln. Anhand der Entwicklungen in der Zahlentheorie lassen sich die Fortschritte des 17.Jahrhunderts gut verfolgen. Durch die Arithmetica von Diophantos wurde Fermat stark inspiriert die Zahlentheorie voranzutreiben. Eine entscheidende Annahme findet man als Randnotiz auf dem Manuskript seines Werkes Arithmetica. Die Fermat'sche Vermutung führte zu vielen wichtigen Arbeiten in der Algebra und der Zahlentheorie. Während des 17.Jahrhunderts gab es zwei wichtige Entwicklungen in der reinen Geometrie. Die erste steht in Descartes' Werk Discours de la Méthode (1637). In dem Anhang La Géométrie berichtet Descartes über die Entdeckung der analytischen Geometrie. Er zeigte, wie man die Algebra für Untersuchungen der Geometrie von Kurven verwenden konnte. (Fermat machte zwar dieselbe Entdeckung, aber er veröffentlichte sie nicht.) Die zweite Entwicklung in der Geometrie war die Publikation des französischen Technikers Gérard Desargues seiner Entdeckung der projektiven Geometrie im Jahr 1639.

Aryabhata's 499 AD computation of pi as 3.1416 (real value 3.1415926...) and the length of a solar year as 365.358 days were also extremely accurate by the standards of the next thousand years. * Astronomical time spans: * Theory of creation of the universe: A 9th century Hindu scripture, The Mahapurana by Jinasena claims the something as modern as the following: (translation from [5]) Some foolish men declare that a Creator made the world. The doctrine that the world was created is ill-advised, and should be rejected. If God created the world, where was he before creation?... How could God have made the world without any raw material? If you say He made this first, and then the world, you are faced with an endless regression... Know that the world is uncreated, as time itself is, without beginning and end. And it is based on principles. Theories of the creation of universe are present in almost every culture. Mostly they represent some story portraying creation from mating of Gods or humans, or from some divine egg, essentially all of them reflecting the human endeavour to provide explanations to a grave scientific question using common human experience.

Si tratta di nozioni in parte assai precise , in parte sostanzialmente errate , e fu scritto da Aryabhata Aryabhata (A.D. 476-542) nacque lungo le rive del Gange, nei pressi della moderna città Patna , a 400 chilometri da Calcutta. L'Aryabhatiya, più che un testo di teoria matematica, è una sorta di riassunto , un catalogo di regole. Ci sono, fra l’altro , regole fondamentali della trigonometria, la descrizione del movimento di stelle e pianeti, la valutazione del pigreco, e la lunghezza dell’anno solare. Mentre la lunghezza dell’anno tropico è notevolmente imprecisa , il valore di pigreco è un dato preciso . In merito a quest'ultimo, Aryabhata, infatti, scrisse la celebre frase:

History of Indian Astronomy Suggested Text Treasures of Ancient Indian Astronomy A ncient Indians' interest in astronomy was an extension of their religious preoccupations and inasmuch, astronomy and mathematics ran parallel. Both were faithful to the needs of objectivity and subjectivity. Astronomy began as mere wonder at what was observed in the heavens above, grew into a systematic observation and speculation, hence forward into scientific inquiry and interpretation, finally emerging as a sophisticated discipline. Mystical interpretations of the movement of stars and planets developed into astrological science, and astronomy grew into a major factor in the intellectual pursuits of different cultural periods. The chief sources of astronomy-related information are the Vedic texts, Jain literature, and the siddhantas (texts), as also the endeavours in Kerala. Some seals of the Indus Valley period are believed to yield information of the knowledge available to those early settlers, as also the orientation of certain constructions clearly governed by such considerations. An interesting aspect is the Jantar Mantar observatories built by Sawai Jai Singh of Jaipur. There are 5 such structures for measuring time and for astronomy-related calculations, at New Delhi, Varanasi, Jaipur, Mathura and Ujjain. These eighteenth century astrolabes are important for both scientific and architectural reasons. Sawai Jai Singh, in his determination to provide accurate astrological tables, ordered these gigantic structures of stone. The Jaipur observatory includes the largest sundial in the world with a 90 feet high projecting arm (the gnomon). The measurements achieved by these Jantar Mantars were particularly impressive for their time - the astronomical table was very accurate and in some instances, better than contemporary western ones. This table was published in Persian and Sanskrit as the Zij Muhammad Shahi. The time was and is calculated by a study of the shadows cast by the central straight walls on to the curved walls beyond. The weather forecasts and other information provided by these sundials are very much in use at present, for religious and practical purposes.

Astronomical time spans: The notion of of time spans that are truly gigantic by modern standards are rarely found in ancient civilizations as the notion of large number is rare commodity. Apart from the peoples of the Mayan civilization, the ancient Hindus appear to be the only people who even thought beyond a few thousand years. In the famed book Cosmos , physicist-astronomer-teacher Carl Sagan writes "... The dates on Mayan inscriptions also range deep into the past and occasionally far into the future. One inscription refers to a time more than a million years ago and another perhaps refers to events of 400 million years ago, ... The events memorialized may be mythical, but the time scales are pridigious".
