Answer 2

.Copernicus (1473-1543)

Ptolemaic System

Planets appear to reverse motions at times.
Ptolemy explained motions in terms of orbits (epicycles) carried on a larger orbit (deferent).
Epicycle deferent ratios were very close to modern values of planet/earth orbit ratios. System worked very well.
Contrary to popular myths, Ptolemy's system was not overly cumbersome, and it accounted for subtleties like the uneven motion of the Sun
It is not Ptolemy's fault he did such a good job that it took 1500 years to improve on him!

Answer 3

..Galileo (1564-1642)

Galileo's most original contributions to science were in mechanics: he helped clarify concepts of acceleration, velocity, and instantaneous motion.

Galileo's effect on Astronomy

Galileo did not invent the telescope (known since at least 1590).
One of the first to use a telescope on the heavens. Found observational evidence against traditional views.
Craters on moon
Phases of Venus
Satellites of Jupiter
Others independently used telescopes on celestial objects at nearly the same time. Galileo had the best publicity.
Main impact: An aggressive popularizer of Copernican viewpoint and satirist of Aristotelian physics.
Kepler (1572-1630), Brahe (1546-1601)

Kepler was a medieval mystic.

One of the last of the "scientific astrologers."
Attempted to explain spacing of planet orbits by reference to Platonic solids.
Kepler was reluctant to abandon perfectly circular motion (but despite his mystic tendencies, he did when the evidence required it).
Kepler found many numerological relationships among the planets, of which "Kepler's Laws" are the three that have proven to have a physical basis.
Kepler's concept of the Sun as center of solar system may have had a mystical basis.
