  Francis Bacon would create the Scientific Method which is an approach that today many sicentists use.

  Galileo expanded on the Heliocentric theory and made it a more plausable theory.

  Tycho Brahe would use this major event to discover more about comets and that they came above Earth's atmosphere. (Wikipedia)

  William Harvey would expand on the human anatomy and develop the idea of the blood circulation in his book, On the Movement of the Heart and the Blood in 1648.

  Rene Descartes would use another philosophical theory, the deduction method. He belived that one had to prove something before it could be accepted as correct.

  Giordianno Bruno was burned at the stake for heresy due to his belief in the Heliocentric theory. This was significant because it was the Catholic church's way of trying to stop the spread of the idea but it was too late.

  This was another book written by Isaac Newton and it is considered equally important. It was also about the physics. It focused on the reflections of lights. (wikipedia)
