Astronomy: Copernicus and Tycho Brahe

Study Notes

Proposed by a Polish astronomer known as the Father of Modern Astronomy.
This model places the Sun at the center of the solar system, challenging the geocentric view.

Developed the Tychonic System, a hybrid model incorporating both geocentric and heliocentric elements.
Designed innovative astronomical instruments, including a large sextant and a building-sized quadrant for precise measurements.
Established Uraniborg observatory with the support of King Frederick II in 1576.
Served as the imperial astronomer in Prague, invited by the Holy Roman Emperor.
His meticulous observations of the Sun revealed inaccuracies in the Julian calendar, resulting in the adoption of the Gregorian calendar in 1582.
Compiled a star catalogue that accurately positioned over 800 stars, marking the first significant update since Ptolemy.

Italian scientist recognized for advancing modern astronomy through improvements to the telescope.
Conducted extensive observations supporting Copernican heliocentrism.
Formulated the Three Laws of Planetary Motion, reinforcing the heliocentric model.
Discovered the first variable star, demonstrating his innovative approach to celestial observation.
Created a comprehensive atlas of the Moon.

English physicist and mathematician who established the laws of motion and universal gravitation.
His theories dramatically transformed the understanding of celestial mechanics and motion.
Developed the Theory of Special Relativity in 1905 and the Theory of General Relativity in 1915, greatly impacting physics and astronomy.
