Telescope

Galileo made a 3-power telescope. After some refinement, he brought a 10-power telescope to Venice. On one fall evening the scientist trained his telescope on an object in the sky that all people at that time believed must be a perfect, smooth, polished heavenly body know as the Moon. Galileo viewed a surface that was uneven, rough, and full of cavities and prominences. This caused people say that he was lieing and also insisted that Galileo was wrong. Some of their arguments were that even if Galileo was seeing a rough surface on the Moon, that only meant that the entire moon had to been covered in invisible, transparent, smooth crystal.

Pendululm

When Galileo was twenty he noticed a lamp swinging while he was in a cathedral. He was curious to find out how long it took the lamp to swing back and forth, so he used his pulse to time large and small swings. Galileo discovered something that no one else had. He found out that the period of each swing was exactly the same. The law of the pendulum made Galileo Galilei instantly famous. This would soon be used to resemble a clock.

The Leaning Tower of Pisa- Proving Aristotle wrong!

When Galileo arrived at the University, some debate had started on one of Aristotle's laws of nature, this is a heavier objects would fall faster than lighter objects. Aristotle's word had been accepted as the truth. Galileo decided to try. He needed to be able to drop the objects from a great height, the perfect building was the Tower of Pisa, witch was 54 meters tall. Galileo climbed up to the top of the building carrying a variety of balls of different sizes and weight, and dumped them off of the top. They all landed at the base of the building at the same time. This proved that Aristotle was wrong.

Compasses

Galileo needed to come up with something that could make him a profit. He found great success in 1596 with a military compass that could be used to accurately aim cannonballs. A modified civilian version that could be used for land surveying came out in 1597
