Biography

Galileo was born in Pisa, Italy in 1564. As a young boy, he was fascinated by the idea of viewing far away objects while watching a Dutch lensmaker make a lens himself. In 1609, he decided to construct his own telescope. Using his technology, he found that Jupiter has four moons, the sun has dark spots, and Earth’s moon has a rough uneven surface. Galileo disproved Aristotle's theory that the stars and moon were made of refined or pure substances. His research caused controversy with the Catholic Church and their beliefs. Eventually, Galileo was put under house arrest because of his support of Copernicus's heliocentric theory, even after the church warned him that the geocentric theory is what they believe in. While he was under house arrest, he died in 1642. To this day, none of Galileo’s theory's or findings have been out ruled or disproven.

Enlightenment Ideas

Telescope- inspired by an old Dutch lensmaker, Galileo created a telescope so he could research the heavens

Moons of Jupiter- with his telescope, Galileo concluded that Jupiter has four moons.

Dark spots on the sun- also with his telescope, he saw dark spots on the sun that nobody had seen before

Moon has rough surface- he proved Aristotle's theory wrong by seeing a darker, uneven surface on the moon

Rings of Saturn- he used his telescope to be the first observer of Saturn’s four groups of rings

Proved Copernicus's heliocentric theory- with the findings of Venus’s phases, he noticed that there are phase changes whenever Venus circles the sun, concluding that the planets circle the sun.

Phases of Venus- disproving Ptolemaic model, and agreeing with Copernicus's heliocentric theory, he observed that Venus has different phases, just like our moon, when it revolves around the sun

Pendulum clock- he took the first steps in having a device that tells time by using the pendulum to regularize each second.He made a clock inspired by his mathematical approach to motion, that moved at a universal time which helped in many aspects in studies and arts.

Disproved Aristotelian’s belief that heavy items fell much quicker than lighter ones due to gravity, and that weight has nothing to do with

These inventions and realizations refreshed the people's views on astronomy, religion, and research believed to be true for years. The enlightenment is the epitome of reason and individualism replacing tradition, such as when he proved the church’s beliefs to be incorrect

Modern legacy

Galileo Galilei has many affects on today's world. He paved a way to the invention of the first clock by using a pendulum and it's constant swing to regulate the device. He was inspired by the Dutch lens-maker, and after making his telescope, he excelled in researching the universe. Without his discoveries the modern world would have been delayed in finding many things about the solar system. Much larger telescopes have been created today, and we can see the surfaces of planets billions of miles away. These feats would not have been possible without the first telescope used to view the sky.

Galileo was known for making educated guesses and then experimenting with his hypotheses. Everyday scientists use hypotheses and make predictions and go off of that in their research In order to obtain proof. He also used prior discoveries to aid his own research, which is a technique modern science uses today.
