The British mathematician Sir Andrew Wiles (born 1953) is best known for proving Fermats Last Theorem, which, until then, was one of the most famous unsolved problems in mathematics. [52], Ptolemy wrote an astrological treatise, in four parts, known by the Greek term Tetrabiblos (lit. This is similar to the Twin Prime conjecture, which states that there are infinitely many pairs exactly 2 apart (for example 11 and 13) but no one knows if this is true. Further, we can say that all of his theories depend heavily on fabricated data, and some of them seem to depend completely upon such data. Ada Lovelace (1815 1852) was an English writer and mathematician. Qin first developed a method for numerically solving polynomial equations, which is now known as Horners method.

She also wrote the first algorithm to run on such a machine (to calculate Bernoulli numbers), making her the first computer programmer in history. During his lifetime, the roles of scientist and philosopher had so much overlap that they were virtually indistinguishable. [4] However, it is likely that only a few truly mastered the mathematics necessary to understand his works, as evidenced particularly by the many abridged and watered-down introductions to Ptolemy's astronomy that were popular among the Arabs and Byzantines alike. Lambert also worked on geometry and cartography, created map projections, and foreshadowed the discovery of non-Euclidean spaces. Euclid taught mathematics in Alexandria, but not much else is known about his life. His family background and childhood are not very clear in history, except his name which some scholars claim was often found in the rich class of Macedonia. Only towards the end of his life, Cantor started to receive the recognition he deserved. and ed.).
