The 15th century Renaissance astronomer Nicolas Copernicus is widely regarded as one of the most influential minds of mathematics and astronomy and a pioneer in starting a scientific revolution. His work led to a rethinking of Ptolemy's geocentric model of the universe to a heliocentric one. However upon closely studying the writings of Copernicus, researchers have discovered that much of his work was identical to that of medieval islamic scholars who lived a few centuries before. The most obvious evidence of Copernicus's use of medieval islamic mathematical texts is a near-perfect copy of a statement of a mathematical theorem along with its proof invented during the 13th century by al-Tusi.
