Galileo

Galileo Galilei will be 446 years today. He was born on February 15, 1564.

Galileo's inventions, such as the telescope, revolutionized our understanding of the universe and paved the way for modern astronomy. His discoveries, like the phases of Venus and the moons of Jupiter, challenged traditional beliefs and laid the foundation for the scientific method. Galileo's work ultimately helped advance human knowledge and shape our modern world.

Galileo raised ecclesiastic hackles because he challenged the church-sanctioned, astronomical doctrine of his day: that the the earth stood at the center of both the solar system and the known universe.

In 1632, Galileo Galilei published his book Dialogue Concerning the Two Chief World System that stated, among other things, that the heliocentric theory of Copernicus was correct.

Well Galileo Galilei didn't really create anything, but he discovered a lot. He discovered many celestial bodies as in Io, Europa, Ganymede, and Callisto, which all are some of Jupiter's moons. He also "started" discovering the Law of Inertia, which Isaac Newton later builds on. He also discovered the Law of the Pendulum and the Law of falling bodies. He also published many books.

In 1633 the Roman Catholic Church forced Galileo to stand trial for his belief that the Earth moves around the Sun. Galileo had to publicly denounce the idea and was sentenced to life imprisonment. He spent the the rest of his life under house arrest. Galileo became blind before he died at Arcetri, near Florence, on January 8, 1642.

Yes Galileo was very important, because if he wasn't born than we might not even now about the stars, the planets, the moon, or even about the universe.

And why is that? That is because Galileo was the one whom discovered it.

Galileo was also the one whom "invented" science, math, and other great things we now do in school today.

Galileo was the one whom invented the telescope, the thermometer, and other great and useful things that we use in our every day lives.

The Bible, specifically Psalms 93 and 96 plus Chronicles 16, which all stated that the Earth was in a fixed place.

Copernicus believed that the sun was the center of the solar system (maybe even the universe) and wrote a book about it, but was so afraid of the Catholic Church that he would not allow it to be published until he was near death.

Galileo also believed the sun was the center of the solar system, and proved that everything did not revolve about the earth by observing the moons of Jupiter (still referred to as Galilean moons) and seeing that they revolved around Jupiter. He wrote a book on his discoveries and was threatened by the Catholic Church and was forced to recant his beliefs. He was placed under 'house arrest' by the Church for the last 9 years of his life. In 1969 the Catholic Church issued an apology to Galileo.

Kepler took many years observations of Tycho Brahe and showed that the planets did not revolve about the Sun in circles, but in ellipses. He also developed 2 other laws about the planets changing speed as the distance from the sun changed as they moved in their elliptical orbit, and about equal areas swept by a line from the planet to the sun in equal time intervals.

Newton used mathematics and his law of universal gravitation to prove Kepler's Laws of Planetary motion were correct.

Galileo was not sterilized before launch because at that time, planetary protection guidelines were not as strict as they are now. It was launched in 1989 before more stringent measures were implemented to prevent contamination of other celestial bodies with Earth's microbes.

Uranus was not discovered by Galileo Galilei. Some of the things that Galileo did discover was that there were four moons around Jupiter and that everything falls at the same speed.

Galileo Galilei was an Italian astronomer, physicist, and mathematician. He is considered one of the key figures in the Scientific Revolution for his contributions to the field of astronomy, particularly his support for the heliocentric theory, which posited that the Earth and other planets revolve around the Sun.

Yes. The geocentric system was long accepted. Briefly the geocentric system used the earth as the center of the universe, thus the sun and planets revolved around the earth as center of the universe. The geocentric system had religious implications of the earth as the seat of "God". The heliocentric system replaced the geocentric system in Copernicus' time, with the sun as the center. This challenged the religious concepts.

The "geocentric" system is still accepted. Locating heavenly bodies still use the RA (Right Ascension) system which is geocentric. Leaving out the question of where "God" lives, the astronomical question is simplicity of astronomy calculations..

Galileo Galilei was born in Pisa, Italy.

That it wasn't the earth that was the center of the solar system but the sun. He tried to explain his theory to the catholic churches but they didn't want to hear it for they didn't like his theory. This caused a contradiction and Galileo was sent to house arrest. He had to publicly say that he was wrong. But Galileo knew he was right and until the day he died he never had a doubt. It was much later that he was proven right.

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.
