Tycho Brahe produce much of his astronomical data, Tycho relied heavily on the then new technique of "prosthaphaeresis", an algorithm for approximating products based on trigonometric identities that predated logarithms. Although Tycho admired Copernicus and was the first to teach his theory in Denmark, he was unable to reconcile Copernican theory with the basic laws of Aristotelian physics, that he considered to be foundational. He was also critical of the observational data that Copernicus built his theory on, which he correctly considered to have a high margin of error. Instead, Tycho proposed a "geo-heliocentric" system in which the Sun and Moon orbited
Herrevad Abbey studies abroad suggested that he live at Herrevad. Bille paid for the construction of a laboratory in one of the old monastery buildings for Brahe to use. He used the laboratory to invent an improvement for the manufacture of paper. By 1570 Brahe was producing paper in Scandinavia for the first time at the Klippan Mill near Herrevad. At his request a glassworks was also constructed at Herrevad, the first in the country. Tycho Brahe became a world-famous astronomer at Herrevad when on the night of 11 November 1572 he recorded a new star "brighter than Venus" located in the
