Mathematical Tables
Mathematical tables are lists of numbers showing the results of a calculation with varying arguments. Trigonometric tables were used in ancient Greece and India for applications to astronomy and celestial navigation, and continued to be widely used until electronic calculators became cheap and plentiful in the 1970s, in order to simplify and drastically speed up computation. Tables of logarithms and trigonometric functions were common in math and science textbooks, and specialized tables were published for numerous applications. History and use The first tables of trigonometric functions known to be made were by Hipparchus (c.190 – c.120 BCE) and Menelaus (c.70–140 CE), but both have been lost. Along with the surviving table of Ptolemy (c. 90 – c.168 CE), they were all tables of chords and not of half-chords, that is, the sine function. The table produced by the Indian mathematician Āryabhaṭa (476–550 CE) is considered the first sine table ever constructed. � ...

Matthias Bernegger
Matthias Bernegger (, also ''Matthew'';Jerzy Dobrzycki: ''The reception of Copernicus' heliocentric theory'', International Union of the History and Philosophy of Science. Nicolas Copernicus Committe/ref> born 8 February 1582 in Hallstatt, Salzkammergut, died 5 February 1640 in Strasbourg) was a German philologist, astronomer, university professor and writer of Latin works. Life Bernegger's Protestant family was, like other so called ''exulanten'', expelled from Habsburg monarchy during the Counter-Reformation. They settled in Regensburg, where Bernegger attended the Gymnasium. In 1599, the 17-year-old began studies in University of Strasbourg, Strasbourg, mainly in the fields of philology and natural sciences. He was fascinated by astronomy and was in contact with Johannes Kepler and Wilhelm Schickard. Already in 1612, Bernegger had translated a 1606 Italian-language work of Galileo Galilei's into Latin, as ''Tractatus de proportionum instrumento''. In 1632, via their mutual fr ...
