All Is Well

...ANAXIMANDER Anaximander (610 BCE - 546 BCE) was a Milesian School Pre-Socratic Greek Philosopher. Like most of the Pre-Socratics, very little is known of Anaximander’s life. He was born, presumably in 610 BCE, in Ionia, the present day Turkish west coast, and lived in Miletus where he died in 546 BCE. He was of the Milesian school of thought and, while it is still debated among Pre-Socratic scholars, most assert that he was a student of Thales and agree that, at the very least, he was influenced by his theories. He is infamously known for writing a philosophical prose poem known as On Nature, of which only a fragment has been passed down. In that fragment Anaximander innovatively attributes the formation of a regulating system that governs our world, the cosmos. Furthermore, he put forth the radical idea that it is the indefinite (apeiron), in both the principle (archē) and element (stoicheion), from which are the things that are. In addition to such ingenuity, Anaximander also developed innovative ideas and theories in astronomy, biology, geography, and geometry. For Anaximander, the origination of the world could not be reduced to a single element or a collection of elements alone. Rather, one needed to understand that the origin was in both principle and element not definable in a definite sense or attribution. While this was a radical perspective in relation to the more determinate theories of others from the Milesian school, it does seem to have some derivation from older...

Pythagoras

...Mat 105 Midterm Pythagoras One of the ways to really learn about the history of mathematics and its contribution to the living standard of people is by looking into the lives and work history of some of the greatest people who either directly or indirectly has play an important role in the history of mathematics. One of those people is Pythagoras. Pythagoras (circa 572-circa 495 BC) was born at Samos. He then moved to croton in Southern Italy mainly to escape persecution. While in Croton he founded a group of followers who today are referred to many people as Pythagoreans and these groups of people are sometimes regarded by many as a religious society, cult, or a social movement. Pythagoras has contributed immensely to many important aspects such as Philosophy, Mathematics, Mystic, and Science but today he is best known by many people around the world for a theorem named after him known as the Pythagoras theorem. This is a theorem in geometry that states that in a right angle triangle, the area of the square on the hypotenuse is equals to the sum of the areas of the squares of the other two sides and this can be mathematically represented as follow: A2 + B2 = C2 According to a website known as the math open references, among the key things Pythagoras believes in is as follow: “All things are numbers. Mathematics is the basis for everything, and geometry is the highest form of mathematical studies. The physical world can understand through mathematics.” However, one major...

Pythagoras- Pythagorean Theorem

...the man who proved it. Pythagoras was born in 570 BC in Samos, Greece. His father, Mnesarchus, was a merchant from Tyre who traveled abroad. It is rumored that Pythagoras traveled with his father during his early years and was introduced to several influential teachers, including Thales who was a famous Greek philosopher. Several years and many countries later, Pythagoras found himself in Egypt. It was here that he studied at the temple of Diospolis and was also imprisoned during the Persian invasion. During the time he was imprisoned, Pythagoras began to study the religion called Zoroastrianism (Lauer/Schlager, 2001). It was because of these teachings and ideals that Pythagoras eventually moved to Italy. At age 52, while living in Croton, Italy, Pythagoras established the Pythagorean society. It was through this society and his positions in local government that Pythagoras recruited men and women in order to lead them to the pure life with his spiritual and mathematical teachings. Pythagoras believed that number was limiting and gave shape to all matter and he impressed this upon his followers (Gale, 1998). During his time leading the Pythagoreans, Pythagoras not only proved the Pythagorean Theorem, but also made other mathematical contributions. One of those contributions was that a number is an abstract entity, separable from all specifics. He also discovered that the sum of the angles in a triangle is equal to two right angles. While Pythagoras himself provided the world...

Pythagoras

...of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. Since the fourth century AD, Pythagoras has commonly been given credit for creating the Pythagorean Theorem. The theorem dates back to Pythagorean triples found on Megalithic monuments from circa 2500 in Egypt and northern Europe incorporating right triangles with integer sides. The Middle Kingdom Egyptian papyrus Berlin 6619, written between 2000 and 1786 BC, includes a problem whose solution was a Pythagorean triple. Even though the theorem had been previously utilized by the Babylonians and Indians and no evidence shows that Pythagoras worked on or proved this theorem, he and his students are credited for constructing the first proof. Pythagoras was born between 580 and 572 BC on the island Samos of the coast of Greece. As a young man Pythagoras was advised to head to Memphis in Egypt to study with priests who were renowned for their wisdom. It may have been in Egypt that Pythagoras learned geometric principles that fueled the theorem named after him. Pythagoras later migrated to Croton, Calabria, Italy and established a secret religious cult very similar to the earlier Orphic cult. Toward the end of his life, Pythagoras fled Croton because of a plot against him and his followers, Pythagoreans, by a noble of Croton named Cylon. Pythagoras died in Metapontum between 500 and 490 BC around ninety years old from unknown causes. His studies and part in the Pythagorean Theorem...

While growing, Pythagoras had many tutors and sophists that lead him to the path in which he took of math. At the age of 18, Pythagoras meets and got influenced extraordinary by a master of math and astronomy called Thales. Since back then, all the variety of science and math that we now have, were very limited due to the lack of scientific discovery. The main section of study before was philosophy, and years after, a cluster of subject’s appeared with the root word “logos” meaning the study of something that requires logic. Furthermore,...

Greek Philosophy

...Running head: GREEK PHILOSOPHY Greek Philosophy Cherese Howard HUM 100 November 03, 2009 Felix Figueroa Greek Philosophy Greek Philosophy is a great civilization that is very much still a part of our culture and everyday living of today. These great men discovered things that were too advance for their life time. Without them, society of today will not have geometry, logic or natural sciences. The term philosophy is Greek in origin meaning “love of wisdom.” (Owens, 2003) Pythagoras suggested that “wisdom is something divine and man cannot be truly wise but a lover of wisdom.” (Owen, 2003) Greek philosophy began around 1200 B.C.E. Historians believe that it was born on the south-west coast of Turkey, in a city-state called Milatos. This was near the end of the Minoan period which did not make it past the Bronze Age civilizations. The city was then refounded by Ionian Greeks in the eleventh century B.C.E. Historians also believed that a young man from Miletus was one of the founding fathers of Natural Greek Philosophy, which questions “nature and the natural causes of what occurs in the cosmos.” (Beginnings of Greek Philosophy, pg 240) Thales believed “that everything is the world is made up of matter which might take various forms like solid, liquid, or a gas.” (Beginnings of Greek Philosophy, pg 240) He knew that water could take on all three forms. Thales knew that he could take a piece of ice and apply heat to it and it will turn into water...

Philosophy

...| Greeks | CHAPTER 1 CHAPTER 1 Chinese | Indians and Hindus | Islam | God | Ancient Greek theology was polytheistic, based on the assumptions that there were many gods and goddesses. | The idea of Heaven (T’ien) plays a prominent role in indigenous Chinese religion. The term can refer to a god, an impersonal power, or both. The concept Is now well-defined, and religious scholars have had a difficult time deciding whether T’ien was believed to be a force like fate or a personal identity. It is also unclear whether the ancient Chinese believed T’ien responded to human supplication or simply worked in accordance with the principles of T’ien. | God created human beings and everything. | Monotheism, belief in one God, is the most important and foundational concept in Islam. Muslims believe in one God who created the universe and has power over everything within it. He is unique and exalted above everything. He creates, and His greatness cannot be compared to His creation. | Man | Men had the dominant role in public life in ancient Greece. They were engaged iin politics and public events, while women were often encouraged to stay in the home. | For the Chinese then, Philosophy is the translation of words into action or the application of theory into praxis. Thus for the Chinese, philosophy singles out a person to live on what he says/teaches thus, a man/woman of integrity who has word/s of honor. | In Hindu tradition, Manu is the name accorded to a progenitor of humanity...

Thales of Miletus Phi/105

...As much as I favorite Heraclitus for his obscure, negative outlooks, and mysterious sayings, I would have to say that Thales of Miletus (in my opinion), has the most compelling ideas and philosophies in the pre-Socratic ages. He was usually credited for being the first systematic philosopher of the Western World. He believed that there was an explanation for everything instead of believing/ promoting supernatural causes. "Aristotle, the major source for Thales's philosophy and science, identified Thales as the first person to investigate the basic principles, the question of the originating substances of matter and, therefore, as the founder of the school of natural philosophy. Thales was interested in almost everything, investigating almost all areas of knowledge, philosophy, history, science, mathematics, engineering, geography, and politics." (Thales of Miletus, http://www.iep.utm.edu/thales/) He often developed logical, geometrical theories, such as devising some that allowed hi to measure the height of the pyramids from the ground, and used his intelligence and understanding of the world to predict crop outcomes, and be very profitable at it. It is also pretty interesting to find out that he was technically the first person to study electricity. "LORDZB" states, "It had been noticed that amber, when rubbed, attracted threads of fiber to it. It was this static electricity which Thales’ studied. When the negative particle of the atom was named it was called...
