Galileo improved the telescope and made many significant discoveries in astronomy. His findings encouraged him to speak out for the Copernican view that the earth revolved around the sun. However, his views were considered heretical, and he was placed under house arrest. ]]> 2017-04-27 16:39:58 UTC https://padlet.com/kkristina010/4ruugr02m7wt/wish/168691679 kkristina010 https://padlet.com/kkristina010/4ruugr02m7wt/wish/168698787 Galileo came to the same conclusions of Copernicus – that the sun was the centre of the universe and not the earth. Galileo was also a great admirer of Johannes Kepler for his work on planetary motions.

By inventing the world’s first powerful telescope, Galileo was able to make many ground-breaking explorations of the universe. Galileo’s His telescopes increased magnification from around just 2x to around 30x magnification. Using this new telescope he found that:
  • Saturn had a beautiful ring of clouds.
  • The moon was not flat but had mountains and craters.
  • Using his own telescope, he discovered four moons of Jupiter – Io, Ganymede, Callisto, and Europa. He also noted these moons revolved around Jupiter rather than the sun.

To support the theory of heliocentrism, Galileo had the mathematical proofs of Copernicus but also new proofs from the science of astronomy.

In this pamphlet, Galileo appeared to ridicule the words of Pope Urban VIII – making the Pope less sympathetic to Galileo. As a consequence, Galileo was arrested and imprisoned for several months. He was convicted of heresy and was forced to recant his beliefs. One apocryphal story relates to how Galileo, after recanting his scientific beliefs, muttered under his breath – the rebellious phrase: “And yet it moves.”]]> 2017-04-27 17:14:32 UTC https://padlet.com/kkristina010/4ruugr02m7wt/wish/168702578 He spent the remaining years of his life under house arrest at Arceti. kkristina010 https://padlet.com/kkristina010/4ruugr02m7wt/wish/168702921 Despite being censured by the church, Galileo continued to make discoveries until death overtook him in 1642. Under house arrest, he was able to write Two New Sciences; this summarised his earlier work on the new sciences now called kinematics and the strength of materials. One of Galileo’s significant contributions to the Scientific Revolution was to depict the laws of nature in mathematical terms but also to make an effective use of experiment and observation to develop theories.]]> 2017-04-27 17:15:40 UTC https://padlet.com/kkristina010/4ruugr02m7wt/wish/168702921 kkristina010 https://padlet.com/kkristina010/4ruugr02m7wt/wish/168705890 2017-04-27 17:25:19 UTC https://padlet.com/kkristina010/4ruugr02m7wt/wish/168705890 kkristina010 https://padlet.com/kkristina010/4ruugr02m7wt/wish/168706248 2017-04-27 17:26:20 UTC https://padlet.com/kkristina010/4ruugr02m7wt/wish/168706248
