Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Ya q b ibn riq was an 8th century Persian astronomer and mathematician. Ya q b lived in Baghdad, and is considered to be one of the greatest astronomers of his time. In 767 AD, at the court of al-Mansur, he probably met the Hindu Kankah (or Mankah?), who had brought there the Siddhanta. He wrote memoirs on the sphere (c. 777), on the division of the kardaja; and a zij, or collection of astronomical tables, derived from the Siddhanta, entitled Az-Z j al-Mahlul min as-Sindhind li-Darajat Daraja. He died in 796 AD. In 1030, Abu Rayhan Biruni, in his Indica, tabulated Yaq b''s estimates for the distances of all the celestial bodies from the Earth and their diameters. For example, Yaq b estimated Jupiter''s diameter as 20,000 farsakhs, equivalent to 60,000 miles, according to Biruni''s conversion of 1 farsakh to 3 miles. This comes closer to the currently accepted of value of 88,748 miles than any previous known estimates.
