Scientific Revolution!

  • Feb 19, 1473


    Nicolas Copernicus publishes De Revolutionibus Orbium Coelestium (Revolutions of Celestial Bodies) Upon careful examination of the motions of heavenly bodies, Copernicus rejected the accepted geocentric theory (the Earth is at the center of the solar system), in favor of a heliocentric theory (the Earth is one of a number of planets orbiting a central body, aka the sun). (19 February 1473 – 24 May 1543)

    Andreas Vesalius

    Andreas Vesalius publishes De humani corporis fabrica, (This talks about the Fabric of the Human Body). This is considered to be the first great modern work of science and the foundation of biology. He found that the circulation of blood is a function of the heart when it's pumping. He also assembled the first human skeleton from cutting open dead bodies. (Brussels, December 31, 1514 - Zakynthos, October 15, 1564)

    Tycho Brahemade

    Tycho Brahemade extensive and more accurate naked eye observations of the planets in the late 1500s. These became the basic data for Kepler's studies. He was also one of the first to support Copernicus's view that the Earth revolves around the Sun.He was granted an estate on the island of Hven and the funding to build the Uraniborg, an early research institute, where he built large astronomical instruments and took many careful measurements (14 December 1546 – 24 October 1601

    Galileo demonstrates that a light object and a heavy object made of the same material, dropped at the same time, will hit the ground at the same time. This was in contrast to the Aristotelian system that heavy objects fall faster than lighter objects. He shows this demonstration in his 1638 Discovery on Two New Sciences. 15 February 1564 – 8 January 1642)
  • Antonie Philips van Leeuwenhoek

    Antonie Philips van Leeuwenhoek made alot of powerful single lens microscopes (over 400 different types). He made extensive observations, saying hello to the world of microbiology. Between 1674 and 1682 he made many important observations and discoveries including protists, bacteria, spermatozoa, and the banded pattern of muscular fibers. ((born on October 24, 1632 and died on August 26)
  • Newton

    His treatise Philosophiae Naturalis Principia Mathematica, is said to be his greatest single work in the history of science, described universal gravitation and the three laws of motion. Newton and Gottfried Leibniz's development of calculusopened up new applications of the methods of
    mathematics to science. He showed that an inverse square law for gravity explained the elliptical orbits of the planets
    December 1642 – 20 March 1727])
