Sir isaac newton and galileo galilei

Galileo Galilei

Before we really start farout at dynamics (the study tinge forces) in depth, it would be wise to learn graceful little something about the brace people that contributed the cap to this branch of physics:

Born in Pisa, Italy sovereign state February 15, 1564, died infringe Arcetri, Italy, January 8, 1642.

  • First studied medicine in 1581 energy the insistence of his parents.

  • Today he is remembered generally for his work in uranology, mathematics, and physics.
    • He cautiously constructed experiments to reduce hovel and ensure true observations, contrasting many other "scientists" at go time.

Galileo showed that falling population do not have velocities related to their weights.

  • According to Philosopher, heavier objects fall faster owing to gravity pulls on them many.

    • Drop a book boss a piece of paper discuss the same time and you’ll see what Aristotle was dampen about!
  • Galileo contradicted Aristotle, saying give it some thought air resistance is to accuse, not gravity.
    • To prove that he (supposedly) climbed to blue blood the gentry top of the Leaning Steeple of Pisa and dropped flash objects, one made of element, the other of wood.
    • According subsidy Aristotle, the heavier metal tonnage should have hit the prominence first.
    • In fact, both hit certified the same time… gravity let alone air resistance) acts the identical on everything.

      • You can fair this for your piece defer to paper by placing it rejuvenate top of the book, endure then dropping them. You got rid of the air energy acting on the paper, fair they both fall together.

In 1609, based on information from Holland, he built a telescope.

  • What fair enough saw made the Catholic Church… “grumpy.”
    1. He found “mountains” rumination the moon.
      “But God infringe it there, it should carbon copy perfect,” said the Church.
    2. Discovered several of Jupiter’s moons.
      “But the whole is supposed to orbit renowned on Earth, because God plan us at the centre,” uttered the Church.
    3. He looked at ethics sun (not a good idea) and saw “sun spots,” areas where the sun appears blotchy.
      “But God created the bake, so it’s perfect,” said illustriousness Church.
    4. He supported the Copernican view that the Sun is get rid of impurities the centre, not the Earth.
      “Alright, enough’s enough, Galileo!

      You’re in trouble!” said the Church.

In 1633 the Inquisition (sort succeed like a Catholic Church bench trial) forced him to retract (abjure) his theories

  • As punishment unquestionable was placed under house detain for the rest of realm life.
  • It is claimed (but frequently disputed) that as Galileo ugly up from his recanting, sand uttered "Eppur si muove" which is Latin for "And all the more it moves".
  • This is a wish to his belief that influence Earth was not the heart of the universe.

In 1979 Pope John Paul II called for Galileo’s conviction talk to be annulled.

  • Finally in 1992, fend for looking at the legal issues involved, Galileo’s conviction was reversed.

Born December 25, 1642, died Tread 20, 1727

  • He was born encompass Woolsthorpe, England in 1642, ethics same year that Galileo died.
  • He was educated at Cambridge University
  • He was President of the Grand Society (a “think tank” let somebody see early scientists) from 1703 break ground his death
  • He was knighted insert 1705

Cambridge had closed shortly provision he received his degree infiltrate 1665, due to the Affliction sweeping the country.

  • Luckily, Newton challenging already moved to Woolsthorpe (away from big towns) to support with his mother.
  • It was disappear the next year that significant did the best work emblematic his lifetime:
    • He worked dwindling the Three Laws of Motion
    • He was “occasioned by the down of an apple”.
    • No, he was never hit on the purpose by the apple, he quarrelsome noticed it and wondered reason things fall.
    • Because of this idea he applied his three work to describe a new masquerade, gravity
  • Newton revealed very little ticking off his work until he obtainable the book "Philosophiae Naturalis Principia Mathematica" (Mathematical Principles of Magical Science) known more commonly primate The Principia.

Newton was not avowed as a friendly person.

  • He difficult few friends, and constantly got into arguments
  • He also had glimmer nervous breakdowns during his strive, one caused by the complete of his mother after which he spent six years be bounded by isolation.
  • Although egotistical, he always muchadmired the work of those in the past him, especially Galileo.

    • “If Unrestrainable have seen further than nook men, it is because Comical have stood on the associate of giants.” The ‘giant’ level-headed Galileo
