context_page_description: Jakub Kresa, Spanish: Jacobo Kresa, Latin: Jacobo Kreysa was one of the most important Czech mathematicians of the Baroque era.
context_section_description: Kresa's manuscripts were transcribed for printing by his students František Tillisch and Karel Slavíček, who both later taught at Olomouc.
  The lectures Kresa gave at Charles University were recorded by student called Kryštof John, who published them under the title Mathematica in universitate Pragensi tradica a P. Jacobo Kreysa ... excerpta anno 1685. The manuscript is today stored at the library of Strahov Monastery.
  In Kresa's era the Trigonometric functions were derived using geometry. Kresa was the first to introduce algebraic number to trigonometry.
  Kresa's death was followed by a decline in mathematics and science in the Czech Crown lands due to the dogmatic application of Catholic Church doctrines. With Slavíček having gone to China, scientific work largely  disappeared from the Czech lands for two decades. Although the theories of Isaac Newton, Jacques Cassini and Edmond Halley were well known, local scientists (such as Josef Player or Jan Slezina) were continued to work with the obsolete theories of Ptolemaios and Aristoteles. It was only a quarter of a century later, that scientific work was resumed by peoples such as Jan Antonín Scrinci (1697–1773) and Joseph Stepling (1716–1778).
