a life-long opponent of Copernicanism

Tycho Brahe proposed a model that was a hybrid of [[geocentrism]] and [[heliocentrism]]: in his system, the Moon and the Sun revolved around a fixed Earth, while all other ''planets'' (Mercury, Venus, Mars, Jupiter and Saturn) revolved around the Sun. Mathematically, this model is identical to a heliocentric model<ref>[http://www.bluffton.edu/~bergerd/NSC_111/science3.html Models of the Solar System]</ref>, with the advantage of avoiding the paradoxes of a moving Earth as perceived in his time (no [[stellar paralax]]es, flying birds couldn't mantain flight if the Earth was moving, etc)<ref>[http://www.astro.umass.edu/~mhanner/Lecture_Notes/Jan28_Heliocentric.txt Lecture Notes - UMass Astronomy]</ref>.

*Brahe remained a life-long opponent of [[Copernicanism]]; he was unable to break with the traditional patterns of thought about the earth's lack of motion. And his immense prestige helped to postpone the conversion of other astronomers to the new theory. [http://web.missouri.edu/~hanuscind/8710/Barber1961.pdf]
