10 Interesting Facts About Galileo Galilei | ParallaxNick

Einstein once said that only the work of Galileo can be seen as the real beginning of astronomy and physics. All before that might have been science, but not in a way we are thinking about that term today. Galileo was the first person pointing a telescope to the sky and making incredible observations about our cosmos. He discovered several bodies in our solar system, spotted sunspots, and that the sun rotates and even confirmed the fact that all planets are moving on orbits around the sun, but not the Earth. Especially this last discovery led him into serious trouble with the Catholic Church, and eventually led to a sentence for house arrest to the end of his life. As his life was so amazing and he changed the way we think about physics so heavily, we want to share with you 10 facts about Galileo Galilei you definitely need to know. 1. GALILEO HAS SPENT 10 YEARS UNDER HOUSE ARREST Shortly after Galileo published his book Dialogue Concerning the Two Chief World Systems in 1632, he was sentenced by the Roman Inquisition to imprisonment. Already one day later this was commuted to house arrest. The last 10 years of his life he spent at his villa in Architrae, near Florence. During that time it was prohibited for him to publish any books and the people allowed to visit him were restricted. He was even ordered to read the Seven Penitential Psalms once a week for the next three years. Nevertheless, Galileo received several visitors from Europe, including poet John Milton and philosopher Thomas Hobbes. On one occasion, Galileo was even able to smuggle out his manuscript for his latest book, Discourses and Mathematical Demonstrations Relating to Two New Sciences, which is considered as one of his finest work. It was published in 1638 and was Galileo's final book. In the same year he went completely blind and died on January 8, 1642 at age 77. 2. GALILEO LOST THREE OF HIS FINGERS ALMOST ONE CENTURY AFTER HE DIED This fact seems a bit strange as one might be questioning how an almost 100-year-old corpse can lose three fingers. However, in 1737, almost 100 years after Galileo's death, his body was exhumed from a side chapel at the Church of Santa Croce in Florence, to transfer his remains to the church's main basilica. While doing so, one of Galileo's admirers removed three fingers and a tooth from his body. Although it is not clear who exactly took the fingers and the tooth from Galileo, historians assume that these body parts were handed down through generations of the admirer's relatives. At one point in time, the items were thought to be lost forever. However, in 2009 they appeared again during an auction. The private collector was able to deduce their origin and has returned at least Galileo's middle finger to the authorities. It's currently on exhibition at the Museo Galileo in Florence, Italy. 3. THE CATHOLIC CHURCH DIDN'T ADMIT THAT GALILEO WAS RIGHT UNTIL 1992 It's been a long way since Galileo Galilei was found vehemently suspect of heresy and sentenced to life in prison by the Catholic Church in 1632. Only in 1979, an investigation on the Church's condemnation of Galileo was initiated by Pope John Paul II. It took them 13 years, or even 359 years, since Galileo was sentenced to imprisonment to find a conclusion. In 1992, the Catholic Church closed their investigation and released a formal apology. The statement placed most of the blame on the clerks who worked on Galileo's case during that time, but not on Pope Urban VIII, who presided over the trial. Also, the charge of heresy was never overturned. 4. GALILEO DIDN'T INVENT THE TELESCOPE Although Galileo is often named as the inventor of the telescope, he actually just improved it but did not have the idea from scratch. Instead, the Dutch eyeglass maker Hans Lippesey can be credited with the creation of the telescope. At least, this is what the earliest record of the telescope says. Lippesey tried to patent his idea for the device in 1609, but with no success as it was too easy to copy in the eyes of the Dutch government. In the same year, Galileo learned about the device and developed his own telescope by improving Lippesey's idea significantly. Soon, he had a telescope that could magnify 20 or even 30 times. He started to point the telescope at the Moon and became the first person to realize that this astronomical body is full of craters and mountains against the common belief that it had a smooth surface. With this new device, Galileo was also able to discover certain other astronomical bodies, like the Moon's orbiting Jupiter and Venus, or the fact that these planets are moving on definite orbits. All these discoveries made Galileo famous in a very short period and even led to his appointment as chief mathematician to the Grand Duke of Tuscany, as well as chief mathematician at the University of Pisa. However, his greatest achievement with the telescope was that he proved the theory of Polish mathematician Nicholas Copernicus, that not Earth but the Sun is the center of the solar system. A groundbreaking idea during that time. Number 5 It is very unlikely that Galileo Galilei really dropped anything off the leaning tower of Pisa. Galileo has spent his early life and career in Pisa, so the famous tower in Pisa might be a perfect match to test his theories of motion and falling bodies. However, there is only one written account of Galileo performing some kind of experiment close to what the common myth says. If it's true and Galileo really dropped a large bullet from the top of the tower in Pisa, it would have probably been such a grand spectacle that there would be more documentation about it. As this is not the case, it is highly unlikely that Galileo dropped anything from the leaning tower of Pisa. Number 6 King Louis XIV asked Galileo to discover new planets in the name of France. When Galileo discovered Jupiter and four of its moons in 1610, he immediately rose to fame. He called the moons the Medician stars to honor his patron Cosimo II from the Medici family, who ruled over Tuscany in Italy. As soon as the news spread across Europe, King Louis XIV from France was asking Galileo if he could also name further planets he might discover after him. But Galileo never did. Number 7 The similarity between Galileo's first and last name is no coincidence. During the days of Galileo's lifetime, people in the Italian region of Tuscany used to name their first-born son after the family's last name. As Galileo was the first of six children in his family, he got the pleasure to receive the name of his family as his first name. However, there might also be another explanation that Galileo's first name echoes his last name. According to another common theory, Galileo might also be named after a famous ancestor of his family, Galileo Bonaiuti. Number 8 Galileo Galilei wrote about general relativity long before Einstein did. It seems obvious that this fact about Galileo does not say that Galileo discovered the general theory of relativity long before Einstein did. But nevertheless, he had some similar thoughts on that topic as Einstein almost 300 years after him. Like Einstein, Galileo was also thinking that the term movement might differ based on your personal perception. If you are standing in a windowless cabin on a ship, Galileo proclaimed that you would have no chance to tell if this ship is moving at a steady speed or if it is motionless. That's exactly the same thought Einstein had when thinking about his general theory of relativity. Number 9 Galileo was a college dropout Galileo's father, Vincenzo Galilei, was not a scientist as his son would later become, but a music theorist born in Pisa, Italy. Although Vincenzo was born into a noble family, he was never wealthy, due to the fact Vincenzo never wanted his son to live in poverty and indigence. When Galileo approached him the idea to become a monk, he therefore refused his proposal and enrolled him at the University of Pisa to study medicine. Galileo, however, was never really into medicine, but rather more interested in mathematics and astronomy. So he shifted his focus to these two subjects. In 1585, Galileo eventually left school without earning a degree and continued his studies on his own. To finance these studies, he gave private lessons and turned back in 1589 to the University of Pisa to teach math. Number 10 There was a spacecraft named Galileo In 1989, NASA launched the space shuttle Atlantis, delivering the spacecraft Galileo into orbit. The spacecraft was developed to study the planet Jupiter and several of its moons, as well as also some other bodies in our solar system. Galileo arrived at Jupiter on December 7, 1995 and became the first spacecraft to orbit Jupiter. It is no coincidence that NASA took the name of Galileo Galilei for a spacecraft studying Jupiter, as Galileo himself dedicated a huge part of his life to explore this planet and its moons. The mission came to an end in 2003, when NASA crashed the spacecraft intentionally into Jupiter, to eliminate the risk of the spacecraft to collide with Jupiter's moon Europa and contaminating any potential life there.
