Tycho Brahe
At age 28, in the year 1572 Tycho Brahe made one of many astronomical findings that would change his life. He knew this star was not Venus, because it was too bright and in fact was so bright you could see it during the daytime. He continued to watch this star for eighteen months after initially seeing it. This star is known as a nova, an extremely event and he published his findings the next year. By 1575 he was famous throughout Europe. -
Johann Kepler
In 1609 Kepler discovered his first law of motion which was, "all planets move in elliptical orbits with the Sun at one focus and the other focus empty." He was the first person to fully understand the motions of the planets around the sun. Later he went on to discover his second and third laws of motion. -
Galileo Galilei
January 7 1610, Galileo found three stars rotating Jupiter. The next day he used his telescope to look at Jupiter again and this time the three stars were all to the West side of the planet opposite from last night. This proves that Copernicus' theory is in fact true. -
William Harvey
William Harvey was recognized as a medical leader in his day. Most people of the day believed that food was converted into blood by the liver, then was consumed as fuel by the body but Harvey knew this was wrong. He knew because of human observations and animal dissections. In 1628 he published a book called, "An Anatomical Study of the Motion of the Heart and of the Blood in Animals" which explained how blood was pumped through the body by the heart and how it recirculated. -
Rene Descartes
Rene is often credited with being the "Father of Modern Philosoply" and he was a French mathmatician, scientist and philosopher.

His last major work was in 1649 called "Passions of the Soul" -
