Galileo

Galileo Galilei was hated by some people, particularly those within the Catholic Church, because his support for the heliocentric model of the solar system contradicted the geocentric model endorsed by the Church at the time. This led to conflict with Church authorities who saw his views as heretical and a threat to their religious teachings. His outspoken nature and refusal to back down further fueled the animosity towards him.

Galileo discovered that the speed gained by a ball rolling down an inclined plane is constant and increases linearly with time. This led to the development of the concept of acceleration, where an object's speed changes at a constant rate over time.

well, the bottom mirror peice is supposed to reflect, so use the top open part by the eypeice to view objects, as the bottom of it is suppsoed to reflect like a mirror. so keep the bottom looking up as your eyepiece should be on the shaft toward the top

Galileo Galilei was awarded the title "Chief Mathematician and Philosopher to the Grand Duke of Tuscany" by the Medici family. He was also elected as a member of the Accademia dei Lincei, a prestigious scientific society. Additionally, in 1610, Galileo was appointed as the Chief Mathematician at the University of Pisa.

Because he asked to go there. After Galileo put forth the idea that the earth revolved around the sun, there was a strong reaction from the Church. Up until the time of Galileo, Aristotle's idea of geocentrism, the idea that the sun and other heavenly bodies revolved around the earth, was firmly held. It was seen as blasphemy to offer that heliocentrism, the idea that the sun was the center around which the earth and other planets revolved, was the manner in which the heavens worked. How dare he. Galileo was taken before Church authorities and told to abjure regarding heliocentrism (which essentially means "cease and desist") and that he was going to prison and that none of his work would be allowed to be published. The prison sentence was reduced to house arrest, and arrangements were made for Galileo to stay with the Grand Duke near the Trinita dei Monti. He remained there for a short while but requested to be sent to stay with the Archbishop of Siena, Ascanio Piccolomini, with whom he was friends. This request was granted, and he spent time there before being permitted to return to Arcetri (the location of his villa), near Florence. There he remained for the rest of his days.

Galileo discovered the four largest moons of Jupiter, now known as the Galilean moons: Io, Europa, Ganymede, and Callisto. He also observed the phases of Venus, providing evidence for the heliocentric model of the solar system proposed by Copernicus.

Galileo was allowed to serve his sentence from home due to his age and declining health. Additionally, there were political pressures that influenced this decision, as his work was respected by many influential figures.

Galilo didnt care much for science because he didnt belive in scienctific stuff,(or in other words he didnt belive that the water is H2O) He change his by finding out that his father buit a telescope so he can see the planets and star and the phases of the moon.

Galileo's support for the heliocentric theory (note that this is Copernicus's theory, not Galileo's) got him into trouble with the Roman Catholic Church. In 1633 the Inquisition convicted him of heresy and forced him to recant (publicly withdraw) his support of Copernicus. They sentenced him to life imprisonment, but because of his advanced age allowed him serve his term under house arrest at his villa in Arcetri outside of Florence.

In the opinion of many historians, Galileo Galileo studies of the universe led to Sir Issac Newton's discoveries on the laws of gravity. Galileo's support of Copernicus and his idea that the earth revolved around the sun, led Galileo into prison as this idea went against Church theology. After Galileo recanted he was freed.

I don't participate in competitions or games, so I haven't won anything in that sense. My focus is on providing helpful information and support to users.

it inspired people like the dutch scientist Christiaan Huygens and Isaac Newton. Its important to know what is going on in the universe because it could help us figure out 1. why the universe is the way that it is and 2. what will later happen to the universe that could alter the way we live.

I think that it is because Tycho thought that the sun and the moon orbited Earth but the rest of the planets orbited the sun

So this means that from our perspective if tycho was true then the phases of Venus would look different

Its not a very technical answer sorry so it could do with improving

Galileo left medicine to study mathematics, physics, and astronomy. He became known for his groundbreaking work in these fields and played a key role in the Scientific Revolution.

Galileo did not directly provide evidence for the heliocentric principle but he did discover important evidence that raised doubts about the Ptolemaic system with the Earth at the centre.

First, he discovered the moons of Jupiter, and these were the first objects discovered that definitely orbited round something that was not the Earth. That was one thing.

Secondly, he discovered that Venus has a gibbous phase when seen from Earth in certain positions in its orbit. This is not explained by the Ptolemaic system because Venus cannot go round behind the Sun in the Ptolemaic system.

Again this did not prove the heliocentric principle because Tycho Brahe came up with an intermediate system that had Mercury and Venus orbiting round the Sun, and then the Sun and the other planets orbit round the Earth. So this was still a geocentric system that explained all Venus's phases.

Therefore Galileo did not have enough evidence to prove the heliocentric principle, and after his trial he recanted.

But 60-70 years later enough new evidence had been gathered to convince most people that the Sun is at the centre, as we believe now.

Eudoxus believed in geocentric that means the orbits of the planets go in a perfect circle

No, Tycho's model cannot explain the phases of Venus observed by Galileo. Tycho's model proposed an Earth-centric system with the planets revolving around the Sun, which would not account for the varying phases of Venus. Galileo's observations of Venus' phases provided evidence in support of the heliocentric model proposed by Copernicus.

We'll never know. But it may be worth noting that Galileo supported and played a major role in the theory concerning the heliocentric theory, or the belief that the Sun was at the center of the Solar System.

Mercury was not seen telescopically by Galileo. He observed the Moon, Venus, Jupiter, and its moons, among other celestial objects.

It didn't "frighten" the Church. The Church was upset because Galileo was insisting on a theory that he couldn't prove, at that time - the science hadn't been invented yet. The Church allowed him to publish his theory as a theory, but not to claim it was fact until it was proved. Galileo was a very stubborn man who believed he was right (actually, his theory was right, but he couldn't prove it) and he insisted on teaching it as fact, and he insisted on making fun of the pope who was both a patron and a personal friend - this didn't go over very well with the Church.

Galileo withdrew his theories about the Earth's rotation in order to avoid being persecuted by the Roman Catholic Church. The Church condemned heliocentric ideas as heretical, and Galileo was ultimately forced to recant his views to avoid punishment.

Galileo discovered the moons of Jupiter and observed the phases of Venus, providing evidence to support the heliocentric model of the solar system. Herschel discovered the planet Uranus and infrared radiation, expanding our understanding of the universe.

Galileo was locked up by the Catholic Church in 1633 for his support of the heliocentric model of the universe, which contradicted the Church's geocentric beliefs. He was charged with heresy for advocating the idea that the Earth revolves around the Sun, which was deemed to be against Church doctrine.

Galileo's birthday was on February 15,1564.
