Part 1 of this series explores how the movement grew out of the Church-dominated period of the Middle Ages and how various complex forces gave rise to new scientific discovery. During the Middle Ages, society believed the classical teachings of Aristotle and Plato. The Earth-centered solar system, as described by Ptolemy, was considered fact. The notion that our solar system was actually Sun-centered and that the Earth and other planets moved about the Sun was considered heretical, and scholars who suggested it were executed for their beliefs. This enlightening video follows a chronological journey through the Scientific Revolution, examining the contributions of the various pioneers of the period who risked their lives to advance our understanding of nature. Leonardo da Vinci, Nicolaus Copernicus, Andreas Vesalius, Tycho Brahe, Sir Francis Bacon, and Galileo Galilei are but a few of the brilliant minds who led the way. During this amazing period of history, advances were made in every area of science, including mathematics, physics, astronomy, medicine, botany, chemistry, and the methodology of research and documentation of scientific evidence.
