Galileo

the gravity is the same and will fall at the same time. except if the thing is flat, and there will be air resistance so it will go slower to the ground. eg : paper :)) add me on facebook hanifati sabilaa :p

that art is free-spirited and children have the right to eat dog food

He did not discover the planet Jupiter. He only used his telescope to see its four largest moons. The planet is and always has been visible to the naked eye and was known to people since ancient times.

Galileo DID NOT discover Mars. Mars has always been visible from Earth to the unaided human eye and was known to and named by our ancient ancestors. Galileo is believed to be the first person to view Mars though a telescope in 1609.

Isaac Newton was a very important scientist in history contributing to theories such as the Law of Gravity. One important link to his discovers was he felt science and religion were linked together by science proving belief in his God.

Copernicus produced his model with the Sun at the centre in 1543, and then in 1609 Kepler produced the model that we use now. Kepler's model also uses the idea of having the Sun at the centre. No-one proved anything but after Newton's discoveries in physics it was realised that Kepler's model fitted exactly with Newton's later theories in gravity and dynamics, so that's why it became accepted, and it still is.

He produced increasingly powerful telescopes, through observing Moon's phases he discovered that Moon is not smooth, he discovered four moons revolving around Jupiter, he had discovered the puzzling appearance of Saturn, later to be shown as caused by a ring surrounding it, in Florence he discovered that Venus goes through phases just as the Moon does.

The most important discovery Galileo made to support the heliocentric model was his telescopic observation of the phases of Venus. From Earth, Venus appears in phases like those of the moon's - new, waxing crescent, waxing gibbous, full, waning gibbous, and waning crescent. In the Ptolemaic model Venus is never on the far side of the sun from Earth, and so it would never display the gibbous or full phases. On his first observation to check for Venusian phases he saw a gibbous Venus at once invalidating the Ptolemaic model. Over several months he continued his observations and saw Venus changing phase to half, and waning crescent confirming that Venus orbited the sun.

Leeuwenhoek used the lenses to see the microscopic world (i. e. Microbiology) whereas Galileo used lenses to observe the stars and planets ( i. e. in Astronomy).

Because he had already known the knowledge and he didn't need to it really wasn't required for him but he did become successful so yeah there you go

Galileo died of natural causes in 1642, when he was almost 78 years old. He was already suffering ill-health, having been blind for several years, and also having a hernia. Just prior ti his death, he had a high fever and heart palpitations.

At the time, he was serving life imprisonment (under house arrest) for his writings which contradicted the teaching of the Roman Catholic church and supported Copernicus, who was seen as a heretic.

See the related link below for more information.

He didn't know it, he just brought out a new theory that showed that with the Sun at the centre the planets' paths could be explained more simply.

That was in 1543 and Kepler produced another heliocentric theory in 1609 which had the planets moving in elliptical orbits round the Sun.

The only thing in favour of Kepler's theory at the time was that it explained the planets' positions more accurately than previous theories. But 80-90 years later Newton's discoveries in gravity and the laws of motion were used to prove by theory that the planets must move in elliptical orbits.

Galileo's theory of motion is principle of inertia. It is basically the same thing as Newton's law of motion since he based it on Galileo. It says that an object will remain still or keep moving in constant speed unless affected by another force.

Because he was the first person in the world to draw sketches of the Moon and the Moons of Jupiter.

I think that Galileo died during the same year Newton was born.

Galileo Also Discovered Intertia Leading Isaac Newton To Make The First Law Of Motion Using What Galileo Had Discovered Hope this helped :)

He said he had proof of the heliocentric idea, but refused to reveal it, saying that the cardinals were too stupid to understand it. But later in court he could not produce adequte proof and recanted.

However long after Galileo's death further scientific discoveries forced people to realise that the Sun is at the centre after all. In Galileo's time it was only speculation, not a scientific theory.

Galileo discovered the telescope, and phases of the moon

He believed that everything rotated around the sun. Also, he believed that the planets orbit were not circular, they are oval. He was a catholic, but they didn't like him because he was going against the church with what he believed.

because catholics believed in geocentrism which is the theory that everything revolves around the earth, and for someone to disprove this theory would probably annoy them.
The Church was scared of losing their power/political authority if people found out that there were flaws behind the church's beliefs. They even burned Giordano Bruno at the stake for believing that the stars were suns and that the universe was infinite. The pope at the time then said it heresy to believe in heliocentrism. Heliocentrism meant that the sun was in the center of the solar system and the planets revolved around it. But the church had said that the Earth was in the center. And that the Earth was the center of the universe and that the Catholic church was the center of religion in the world.

Galileo Galilei is known for inventing the telescope, which he used to make astronomical observations that supported the heliocentric model of the solar system. He also improved the design of compasses and thermometers, and made significant contributions to the development of the scientific method.

In actuality, Galileo did not discover any planets. However, he did observe that there were four moons around the planet Jupiter. He also observed through the telescope that Venus and Mercury had phases like the moon.

Cleaner air (hence less lenticular distortion) and no city lights to spoil night time viewing.

Galileo's primary advantage was the use of a telescope. He was the first person to record astronomical observations made with the recently invented device. Aside from a few burning candles and oil lamps, there would have been almost zero light pollution back in the early 17th century. There would have been a lot of haze from fires used for cooking and heating, however, near any sufficiently large town.

It was thought at the time that heavier ojects fall faster.

Galileo performed following thought experiment:

what would happen if you tied two bricks with a piece of a string and throw them from a top of the tower. At some point of the fall, the string is being cut.

If it was true that heavier objects fall faster, the rate of falling of two bricks tied together would be higher than two separate bricks.

That's however untrue.
