    Aryabhata


    0 Not allowed!
    Aryabhata, also called Aryabhata I or Aryabhata the Elder (born 476, possibly Ashmaka or Kusumapura, India), astronomer and the earliest Indian mathematician whose work and history are available to modern scholars. He is also known as Aryabhata I or Aryabhata the Elder to distinguish him from a 10th-century Indian mathematician of the same name. He flourished in Kusumapura—near Patalipurta (Patna), then the capital of the Gupta dynasty—where he composed at least two works, Aryabhatiya (c. 499) and the now lost Aryabhatasiddhanta.

    Aryabhatasiddhanta
    circulated mainly in the northwest of India and, through the Sāsānian dynasty(224–651) of Iran, had a profound influence on the development of Islamic astronomy. Its contents are preserved to some extent in the works of Varahamihira (flourished c. 550), Bhaskara I (flourished c. 629), Brahmagupta (598–c. 665), and others. It is one of the earliest astronomical works to assign the start of each day to midnight.

    Aryabhatiya was particularly popular in South India, where numerous mathematicians over the ensuing millennium wrote commentaries. The work was written in verse couplets and deals with mathematicsand astronomy. Following an introduction that contains astronomical tables and Aryabhata’s system of phonemic number notation in which numbers are represented by a consonant-vowel monosyllable, the work is divided into three sections: Ganita (“Mathematics”), Kala-kriya (“Time Calculations”), and Gola(“Sphere”).

    In Ganita Aryabhata names the first 10 decimal places and gives algorithms for obtaining square and cubic roots, using the decimal number system. Then he treats geometric measurements—employing 62,832/20,000 (= 3.1416) for π—and develops properties of similar right-angled triangles and of two intersecting circles. Using the Pythagorean theorem, he obtained one of the two methods for constructing his table of sines. He also realized that second-order sine difference is proportional to sine. Mathematical series, quadratic equations, compound interest (involving a quadratic equation), proportions (ratios), and the solution of various linear equations are among the arithmetic and algebraictopics included. Aryabhata’s general solution for linear indeterminate equations, which Bhaskara I called kuttakara (“pulverizer”), consisted of breaking the problem down into new problems with successively smaller coefficients—essentially the Euclidean algorithm and related to the method of continued fractions.


    With Kala-kriya Aryabhata turned to astronomy—in particular, treating planetary motion along the ecliptic. The topics include definitions of various units of time, eccentric and epicyclic models of planetary motion (see Hipparchus for earlier Greek models), planetary longitude corrections for different terrestrial locations, and a theory of “lords of the hours and days” (an astrological concept used for determining propitious times for action).



    Aryabhatiya ends with spherical astronomy in Gola, where he applied plane trigonometry to spherical geometry by projecting points and lines on the surface of a sphere onto appropriate planes. Topics include prediction of solar and lunar eclipses and an explicit statement that the apparent westward motion of the stars is due to the spherical Earth’s rotation about its axis. Aryabhata also correctly ascribed the luminosity of the Moon and planets to reflected sunlight.
    The Indian government named its first satellite Aryabhata (launched 1975) in his honour.

    This is a response to the CPed info only:

    The Indian Government should have named the satellite only Sher-e Manzil or Chuha-e Manzil or some such thing. The term Arya denotes invasion of India by the marauders from the Central Asia. And Bhatta adds fuel to the fire as the term has brahminical connotations.

    The Government was communal and chauvinistic to have given this name to the satellite.

    ????

    Why are you linking the word Arya with invaders?

    The Arya word is even present in the Bhagavad Geeta spoken by Shri Krishna..Avatar of Shriman Narayana in Dvapara Yuga.

    All this central asia theory is only Kaliyuga.

    Narayana!

    What is so wrong to name a satelite Aryabhatta?

    Why see a name only tru the lens of caste?
    Everyone who is great be it from a Brahmin community or Dalit or anything else in between who has contributed to the nation can be decorated and there is no need to shy away and hide just becos a name denotes a particular community.

    Did anyone in India object to the naming of the satelite?

    So kutas tva idam persecution complex?

    We should just admire greatness without attaching a caste tag..btw when India named a missile Prithvi(named after the 5 elements) ..what did Pakistan do?

    They named their missile Ghauri becos Mohd Ghauri had gauged out Prithiviraj Chauhans eyes.

    So the Pakistanis saw Prthviraj Chauhan in the missile and created a Ghauri..likewise why do you want to only see Aryabhatta as a Brahmin name that would make others uneasy?

    I would not give that much credit to the post#2.
    It was written purely in hatred and disgust at the original poster and his methods.
    The first line is the clue.
