Galileo
Galileo made many observations and discoveries that helped make our universe better to understand and was a contributor to science and what it is today.
Galileo Galilei born on February 15, 1564 in Pisa, Italy, the oldest of six kids in his family, was an Italian professor, mathematician, physicist, philosopher, astronomer and inventor who made observations of nature for studies for physics. Galileo wrote a number of books on his ideas before his death on January 8, 1642 in Florence, Italy. In his college years his father really pushed for him to study medicine, Galileo's’ heart was in another place which was mathematics at the time. Galileo's contribution with his methods and his use of mathematics

Galileo noted that the frictional forces were decreased, the object would move further and further before stopping. From this a the form of the law of inertia came about; ‘’if the frictional forces could be reduced to exactly zero an object pushed at constant speed across a frictionless surface of infinite extent will continue at that speed forever after we stop pushing, unless a new force acts on it at a later time.’’ (Galileo & The Laws of Dynamics, 5) According to the Aristotle’s observation, that heavier objects fall faster than light ones, Galileo wanted to perform this by doing an experiment from the top of the Leaning tower of Pisa. He dropped two spheres of different weight and observed that both hit the ground at the same time. Galileo correctly reasoned that when an object falls more slowly, it is due to air resistance. An object moving under the influence of gravity is said to be in freefall; while an object near the surface of the Earth such an object falls at an acceleration. With this observation it gave us a better understanding of gravity and how things react with it. In another observation, Galileo observed that there are more stars than what is visible to the human eye, which in today’s world we know that, especially with city lights it's harder to see them but back in this time …show more content…

Galileo’s contributions to the science of Physics and Astronomy were many. His conviction was legendary. His willingness to suffer for his beliefs exemplify true courage in the name of truth, and has inspired others to venture intellectual independence from the Church‘s creeds, edicts, and proclamations. Perhaps these contributions led to the call for an investigation into Galileo's conviction, eventually calling for its reversal, in 1979 by Pope John Paul II. But regardless of his standing in the annals of the Catholic church he will always be the man who began the separation of science and religion.
I think that according to Galileo an individual gains knowledge of nature threw observation. Galileo believed no one really went out into the world as he did and used the senses that God gave us when we where created, to observe the physical world. He was a very persistent individual and was always looking further into what he observed our read. Many people went along with how he gained knowledge of nature but the few who did not tried to find other ways to damage his beliefs and ideas.
In order to distinguish between religion and natural philosophy, Galileo appealed to the centuries old sentiment of observation. If people were able to reproduce or procure their own instrument such as the telescope, they could simply observe the craters and shadows of the moon themselves. People would be able to observe the change in the appearance of the lunar surface in connection to how it was struck by the suns rays (Biagoli 2006, 106). In a broad sense, Galileo was able to build what we would call the basic elements of science today, validity and replicability, which allowed him to divide religion and
Galileo Galilei, (1564-1642) an Italian mathematician and astronomer, won the respect and admiration of many people of his time because of his inventions. He constructed a military compass, an instrument for measuring the expansion of liquids, and one of the early telescopes with which he discovered Jupiter's satellites, irregularities on the surface of the moon, star clusters in the milky way and spots on the surface of the sun. He was initially skeptical of Copernicus' theory however his observations and experiments affirmed his diagram of the universe. Critics attacked Galilei's findings. They said that his "discoveries" were ridiculous to believe and that it was only is imagination or dreams. Galilei wrote a letter to Dowager Grand Duchess trying to reconcile his astronomical observations with the Bible.
In the history of the Catholic Church, no episode is so contested by so many viewpoints as the condemnation of Galileo. The Galileo case, for many, proves the Church abhors science, refuses to abandon outdated teachings, and is clearly not infallible. For staunch Catholics the episode is often a source of embarrassment and frustration. Either way it is undeniable that Galileo’s life sparked a definite change in scientific thought all across Europe and symbolised the struggle between science and the Catholic Church.
Galileo Galilei was born in 1564, and was invested into science. Due to rumors in the year of 1609, about a Dutch who invented a device that zoomed in on distant objects (this was known as a spyglass earlier in the years, now its known as a telescope. He heard that a patent had been requested, but was not granted. There was a lot of value in this because the methods were kept secret, and this could be used in the military for Holland. Due to the rumors, Galilei was soon determined and driven to construct his own spyglass. Within 24 hours, only using his knowledge, experimentation, and pieces of the rumors, and never seeing the actual Dutch spyglass, Galilei soon found himself building a 3-power telescope. With some tweaks, he soon had a 10 power-telescope. From here, he demonstrated this it a Senate, and his salary was raised, and honored with proclamations. This shows how smart Galilei was, being able to construct his own telescope with nothing but his brain.

In 1612, he published his Discourse on Bodies in Water, refuting the Aristotelian explanation of why objects float in water, saying that it wasn’t because of their flat shape, but instead the weight of the object in relation to the water it displaced. In 1623, a friend of Galileo, Cardinal Maffeo Barberini, was selected as Pope Urban VIII. He allowed Galileo to pursue his work on astronomy and even encouraged him to publish it. but it had to be on one condition, it be objective and not advocate Copernican theory.
Galileo used this great invention to report astronomical facts such as the moon is cover with craters instead of being smooth, the Milky Way is composed of millions of stars, and Jupiter have four moons. Perhaps the most famous discovery is the Earth revolves around the Sun and the Earth is not the center of the universe (even though he was discredited at the time).

In 1609 the telescope was invented and Galileo began making his own lenses for better telescopes and then started looking at the sky. In December and January (1609-1610) it is said that he made more discoveries that changed the world that anyone has made before or since. He wrote a book called the “Starry Messenger”, and said that there were mountains on the moon, the Milky Way was made up of many stars, and there were small bodies in orbit around Jupiter. He used his mathematical skills to calculate the motions of these bodies around Jupiter. In 1610 he started looking at Saturn and discovered the rings, and the phases of Saturn (just like our moon’s phases).
