Transcript of History Galileo

Galileo Galilei Full Name:Galileo di Vincenzo Bonaiuti de' Galilei The father of modern observational astronomy and also as the father of modern physics was born on 15th February 1564 Death day:8th January 1642 All of Galileo’s theories and results came from a combination of using mathematics and experiments to find a rational and explainable conclusion Astronomy Another way he proved Ptolemy’s theory wrong was, discovering the phases of Venus. Explaining how it was possible to see the different phases of Venus
Galileo also said in his book The Starry Messenger that the stars were suns, not in orbit to our sun but ones that may have their own planets and moons.
After questioning the church's ideals, he performed experiments and other theories providing the proof that would support those theories. He changed many people's points of view in the field of Astronomy One of Galileo's greatest contributions to astronomy was the creation of the telescope. Technology In 1593 Galileo invented a thermometer using the expansion and contraction of water.
In 1519, he invented the geometric and military compass.
He finished the innovation of the telescope by 1609 and he used it for observational purposes of the sky.
In year 1624 he had finished making the compound microscope, an invention that enabled people to see things that were normally too small to see from the naked eye.
With the help of his inventions he was able to successfully complete his experiments and prove his theories. PHYSICS Galileo was also a physicist who proved and disproved many of his own theories
Galileo performed an experiment in which he took two similar balls but different in mass, and let them drop from the top of the Leaning tower of Pisa.
This was to prove that objects, no matter what size they were, would fall at the same speed, the two balls that he threw landed on the ground at the same time.
His theory of air resistance was later proven by Robert Boyle,this theory also contradicted Aristotle.
Galileo, first to introduce the theory of friction in which he said that due to the inertia of an object it will keep moving in the same motion and direction until it is disturbed.
In his final book,Discourses and Mathematical Demonstrations Relating to Two New Sciences, he tells us all about the experiments that he did using pendulums.
Galileo was one of the first people in the world to say that the laws of nature are mathematical and can be proven by carefully through out experiments. Mathematics Galileo came up with the Galileo Paradox, which says that there are as many perfect squares as there are numbers, but most numbers are not perfect squares. How Galileo contributed to the paradigm shift One major contribution
Discovery of the phases of Venus
Also the moons of Jupiter
Observing, over a period of time how they revovled around other celestial bodies and not Earth
Observed the amount that you could see of moons of Jupiter and Venus at the different times of the year Causes of Galileo's discoveries His discoveries proved Aristotles theories wrong & also challenged the church's authority.
He was brought under the Roman inquisition twice. On the second time he was put under house arrest for the rest of his life. 1632-1642
His discoveries gave visual proof for the people of that time that disproved the Church's theories.It told people to question things for themselves and believe what they see not what they hear.
This is how he contributed to the paradigm shift from a geocentric world view to a heliocentric world view.
