Pythagoras and His Contributions to Modern Society
Transcript of Pythagoras and His Contributions to Modern Society
Pythagoras was born C. 580 B.C. on an island named Samos in the Aegean Sea. He was born into a rich, aristocratic family. His parents were Parthenis and Mnesarchus. Pythagoras is called a Pre-Socratic, or a philosopher before the time of Socrates.
He was the first man in history to call himself a philosopher.
Pythagoras was not only a mathematician, he was also an astronomer, religious philosopher, musician, and a philosopher. Pythagoras' Philosophy Pythagoras founded a secret society in Southern Italy called the Pythagoreans who developed a theory that states that everything in the universe can be explained with numbers, specifically whole numbers. This philosophy is now so common, it is like air to us. For example, because of this genuine idea, we use numbers to calculate wind speeds in a hurricane, calculate the speed of a jet engine, using numbers, which can in turn tell us how long it would take for a jet plane to go from one place to another. Without this philosophy, we would be extremely inaccurate in almost everything we do. Pythagoras' Religion Pythagoras developed a religion called numerology, which is the supernatural infuence of numbers in people's lives. Pythagoras and his followers believed that numbers existed as something independent of what they represent, and that they had unique personalities and characteristics. They also only accepted whole numbers, and disregarded fractions, negative numbers, and even 0! Numerology rarley applies to the modern world, and is now considered to be superstition, although some numbers, such as 3 and 7, are considered "lucky" and can have a large influence on the choices a person makes. Pythagoras also hypothesised that there is something behind the natural world, the supernatural world. This principle is the basic law behind many religions. The Pythagorean Theorem The Pythagorean Theorem states that in a right triangle, the length of the two shorter sides, when squared, are equal to the longest side squared, or the hypotenuse. Ironically, many other civilizations had all ready discovered the "Pythagorean Theorem" before Pythagoras, yet he got all the credit! The Pythagorean Theorem has many real-life applications: Rescue workers use the Pythagorean Theorem to find out the length of their ladders, because, when placed against a wall, the ladder, wall, and ground form a right triangle, making it possible for the Pythagorean Theorem to be applied, construction workers and architects use the Pythagorean Theorem to create right angles in order to keep the building foundation stable, and miners use the Pythagorean Theorem to find out their drilling course. The Pythagorean Theorem can also be applied to many other scenarios. Musical Acomplishments Pythagoras and his followers believed music was an important part of their spiritual and physical life, and often listened to songs that were said to heal wounds, or perform other superstitious acts. Pythagoras discovered that the length and size of strings on musical instruments corresponds to the tone of the musical note it produces.This helps us tune modern day string insruments, such as the violin. Pythagoras was the first to discover musical ratios, or certain notes that, when played at the same time, are considered harmonious to many people. Musical ratios can also be explained through mathematics, such as 2:1. Pythagoras was the first to discover the relationship between music and mathematics. Pythagoras was one of the first to suggest that living beings have souls, and that it is immortal. Astronomical Acomplishments Pythagoras was the first to suggest that the world is round and suspended in space. Pythagoras also stated that the Earth was not the center of the universe. Pythagoras' pioneering ideas influenced many future astronomers, such as Copernicus, and had a large impact on NASA and space travel scientists. Pythagoras' knowledge of the cosmos was made up mainly of two fields, cosmology, which is the study of the origin and nature of the universe, and involved many superstitious facts, and astronomy, which was more of the cold, hard facts. Pythagoras is credited with being the first to use the word kosmos to descirbe the universe, and is the Greek word for harmony, because Pythagoras believed that everything moves in harmony with another body. The Death of Pythagoras Those who opposed Pythagoras banded together and burned his school, but Pythagoras escaped, and while the specific details of his death are not known, he was nearing 100 years old when he died, and he died C. 450 B.C.
