Thread on how Indian Mathematics and Astronomy travelled to the Arab world, often attributed to Arabs and their golden age in mainstream discussions.

In 772 an Indian astronomer travelled to the court at Baghdad and introduced Brahma-sphuta-siddhanta of Brahmagupta(written around 628 CE) The caliph Al-Mansur charged Al-Fazari with its translation, the book was known as As-Sindhind al-Kabir.

The great Persian scholar Al-Khwarizmi(780-850) wrote a book on astronomy borrowing from various sources. The Indian sources were Brahmasidhanta and the much older Suryasidhanta(written in late 4th century).

Al-Khwarizmi(from whom the word Algorithm and later on Algebra comes) wrote his seminal work on Mathematics which explicitly borrowed from previous Indian works. It introduced decimal numeration to the Arab world and later on to Europe.

On the Hindu numeral system, Al-Khwarizmi says – "in no position there is more than 9 nor less than 1, except for the case when there is a ring(zero), which is nothing."

Al-Samawal(1170), a disciple of Al-Karaji in his book Al-Bahir attributed the method of division of two algebraic polynomials to the Indians.

In fact the first great classical work of Arabic literature – a book of fables titled 'Kalila wa Dimna'- is the translation from Pahlavi of an Indian work whose protagonists are two animals, one representing greed and the other one honesty.
