Science during the Renaissance Period

Beginning in the latter half of the 15th cent., a humanist faith in classical scholarship led to the search for
ancient texts, which would increase current scientiļ¬c knowledge. Among the works rediscovered were Galen's physiological and anatomical studies and Ptolemy's Geography. Botany, zoology, magic, alchemy, and astrology were developed during the Renaissance thanks to the study of ancient texts. 

The Scientists and their Inventions

Scientific thinkers like Leonardo Da Vinci, Nicolaus, Copernicus, Galileo, Tcho Brahe and Johannes Kepler attempted to refine earlier thought on astronomy.

In 1543 Copernicus wrote De Revolutionibus, the work that placed the sun at the center of universe and the planets in semicorrect orbital order around it. His work was an attempt to revise the earlier writings of Ptolemy.

Galileo's most important and famous invention was an accurate telescope,  through which he observed heavens. He recorded his observetions in Siderius Nuncius.

Tcho Brahe gave an accurate estimate of planetary positions and refuted the Aristotelian theory that placed the planets within crystal spheres.

Kepler discovered that the planetary orbits were elliptical.
