Philolaus
Philolaus (; grc, Φιλόλαος, ''Philólaos''; ) was a Greek Pythagorean and pre-Socratic philosopher. He was born in a Greek colony in Italy and migrated to Greece. Philolaus has been called one of three most prominent figures in the Pythagorean tradition and the most outstanding figure in the Pythagorean school. Pythagoras developed a school of philosophy that was dominated by both mathematics and mysticism. Most of what is known today about the Pythagorean astronomical system is derived from Philolaus's views. He may have been the first to write about Pythagorean doctrine. According to August Böckh (1819), who cites Nicomachus, Philolaus was the successor of Pythagoras. He argued that at the foundation of everything is the part played by the limiting and limitless, which combine in a harmony. With his assertions that the Earth was not the center of the universe (geocentrism), he is credited with the earliest known discussion of concepts in the development of heliocent ...

Central Fire
An astronomical system positing that the Earth, Moon, Sun, and planets revolve around an unseen "Central Fire" was developed in the fifth century BC and has been attributed to the Pythagorean philosopher Philolaus. The system has been called "the first coherent system in which celestial bodies move in circles", anticipating Copernicus in moving "the earth from the center of the cosmos ndmaking it a planet". Although its concepts of a Central Fire distinct from the Sun, and a nonexistent "Counter-Earth" were erroneous, the system contained the insight that "the apparent motion of the heavenly bodies" was (in large part) due to "the real motion of the observer". How much of the system was intended to explain observed phenomena and how much was based on myth, mysticism, and religion is disputed. While the departure from traditional reasoning is impressive, other than the inclusion of the five visible planets, very little of the Pythagorean system is based on genuine observation. In ret ...

Pythagoreanism
Pythagoreanism originated in the 6th century BC, based on and around the teachings and beliefs held by Pythagoras and his followers, the Pythagoreans. Pythagoras established the first Pythagorean community in the Ancient Greece, ancient Greek colony of Crotone, Kroton, in modern Calabria (Italy). Early Pythagorean communities spread throughout Magna Graecia. Pythagoras' death and disputes about his teachings led to the development of two philosophical traditions within Pythagoreanism. The ''akousmatikoi'' were superseded in the 4th century BC as a significant mendicant school of philosophy by the Cynicism (philosophy), Cynics. The ''mathēmatikoi'' philosophers were absorbed into the Platonic Academy, Platonic school in the 4th century BC. Following political instability in Magna Graecia, some Pythagorean philosophers fled to mainland Greece while others regrouped in Rhegium. By about 400 BC the majority of Pythagorean philosophers had left Italy. Pythagorean ideas exercised a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Counter-Earth
The Counter-Earth is a hypothetical body of the Solar System that orbits on the other side of the solar system from Earth. A Counter-Earth or ''Antichthon'' ( el, Ἀντίχθων) was hypothesized by the pre-Socratic Greek philosopher Philolaus (c. 470 – c. 385 BC) to support his non-geocentric cosmology, in which all objects in the universe revolve around a "Central Fire" (unseen from Earth and distinct from the Sun which also revolves around it). In modern times a hypothetical planet always on the other side of the Sun from Earth has been called a "Counter-Earth", and has been a recurring theme in UFO claims, as well as in fiction (particularly science fiction).

Pre-Socratic
Pre-Socratic philosophy, also known as early Greek philosophy, is ancient Greek philosophy before Socrates. Pre-Socratic philosophers were mostly interested in cosmology, the beginning and the substance of the universe, but the inquiries of these early philosophers spanned the workings of the natural world as well as human society, ethics, and religion. They sought explanations based on natural law rather than the actions of gods. Their work and writing has been almost entirely lost. Knowledge of their views comes from ''testimonia'', i.e. later authors' discussions of the work of pre-Socratics. Philosophy found fertile ground in the ancient Greek world because of the close ties with neighboring civilizations and the rise of autonomous civil entities, ''poleis''. Pre-Socratic philosophy began in the 6th century BCE with the three Milesians: Thales, Anaximander, and Anaximenes. They all attributed the ''arche'' (a word that could take the meaning of "origin," "substance" or "p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heliocentrism
Heliocentrism (also known as the Heliocentric model) is the astronomical model in which the Earth and planets revolve around the Sun at the center of the universe. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center. The notion that the Earth revolves around the Sun had been proposed as early as the third century BC by Aristarchus of Samos, who had been influenced by a concept presented by Philolaus of Croton (c. 470 – 385 BC). In the 5th century BC the Greek Philosophers Philolaus and Hicetas had the thought on different occasions that our Earth was spherical and revolving around a "mystical" central fire, and that this fire regulated the universe. In medieval Europe, however, Aristarchus' heliocentrism attracted little attention—possibly because of the loss of scientific works of the Hellenistic period. It was not until the sixteenth century that a mathematical model of a heliocentric system was presented by the Renaissance mathema ...

Pythagoras
Pythagoras of Samos ( grc, Πυθαγόρας ὁ Σάμιος, Pythagóras ho Sámios, Pythagoras the Samos, Samian, or simply ; in Ionian Greek; ) was an ancient Ionians, Ionian Ancient Greek philosophy, Greek philosopher and the eponymous founder of Pythagoreanism. His political and religious teachings were well known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, through them, the Western philosophy, West in general. Knowledge of his life is clouded by legend, but he appears to have been the son of Mnesarchus, a gem-engraver on the island of Samos. Modern scholars disagree regarding Pythagoras's education and influences, but they do agree that, around 530 BC, he travelled to Crotone, Croton in southern Italy, where he founded a school in which initiates were sworn to secrecy and lived a communal, asceticism, ascetic lifestyle. This lifestyle entailed a number of dietary prohibitions, traditionally said to have included vegetarianism, although m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurytus (Pythagorean)
Eurytus (; grc-gre, Εὔρυτος; fl. 400 BC) was an eminent Pythagorean philosopher who Iamblichus in one passage describes as a native of Croton, while in another, he enumerates him among the Tarentine Pythagoreans. Biography Eurytus was a disciple of Philolaus, and Diogenes Laërtius mentions him among the teachers of Plato, though this statement is very doubtful. It is uncertain whether Eurytus was the author of any work, unless we suppose that the fragment in Stobaeus, which is there ascribed to one Eurytus, belongs to this Eurytus. Through a dubious commentary to Aristotle's ''Metaphysics'' a caricatural image of Eurytus has gained wide currency. A mediaeval writer confused with Alexander of Aphrodisias presented Eurytos as a kind of mosaic-setter who delineated various shapes with some definite number of pebbles.Reviel Netz,''The problem of Pythagorean mathematics'' in ''A History of Pythagoreanism'', ed C. Huffman, Cambridge UP, 2014: " Pseudo-Alexander, writing not ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apeiron
''Apeiron'' (; ) is a Greek word meaning "(that which is) unlimited," "boundless", "infinite", or "indefinite" from ''a-'', "without" and ''peirar'', "end, limit", "boundary", the Ionic Greek form of ''peras'', "end, limit, boundary". Origin of everything The ''apeiron'' is central to the cosmological theory created by Anaximander, a 6th-century BC pre-Socratic Greek philosopher whose work is mostly lost. From the few existing fragments, we learn that he believed the beginning or ultimate reality (''arche'') is eternal and infinite, or boundless (''apeiron''), subject to neither old age nor decay, which perpetually yields fresh materials from which everything we can perceive is derived. ''Apeiron'' generated the opposites (hot–cold, wet–dry, etc.) which acted on the creation of the world (cf. Heraclitus). Everything is generated from ''apeiron'' and then it is destroyed by going back to ''apeiron'', according to necessity. He believed that infinite worlds are generated f ...

Crotone
Crotone (, ; nap, label= Crotonese, Cutrone or ) is a city and ''comune'' in Calabria, Italy. Founded as the Achaean colony of Kroton ( grc, Κρότων or ; la, Crotona) in Magna Graecia, it was known as Cotrone from the Middle Ages until 1928, when its name was changed to the current one. In 1992, it became the capital of the newly established Province of Crotone. , its population was about 65,000. History Croton's ''oikistes'' (founder) was Myscellus, who came from the city of Rhypes in Achaea in the northern Peloponnese. He established the city in c. 710 BC and it soon became one of the most flourishing cities of Magna Graecia with a population between 50,000 and 80,000 around 500 BC. Its inhabitants were famous for their physical strength and for the simple sobriety of their lives. From 588 BC onwards, Croton produced many generations of winners in the Olympics and the other Panhellenic Games, the most famous of whom was Milo of Croton. According to Herodotus (3.131), ...

Universe
The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together ago, and the universe has been expanding ever since the Big Bang. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day. Some of the earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System. In developing the law of universal gravitation, Isaac Newton built upon Copernicus's work as well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taranto
Taranto (, also ; ; nap, label= Tarantino, Tarde; Latin: Tarentum; Old Italian: ''Tarento''; Ancient Greek: Τάρᾱς) is a coastal city in Apulia, Southern Italy. It is the capital of the Province of Taranto, serving as an important commercial port as well as the main Italian naval base. Founded by Spartans in the 8th century BC during the period of Greek colonisation, Taranto was among the most important in Magna Graecia, becoming a cultural, economic and military power that gave birth to philosophers, strategists, writers and athletes such as Archytas, Aristoxenus, Livius Andronicus, Heracleides, Iccus, Cleinias, Leonidas, Lysis and Sosibius. By 500 BC, the city was among the largest in the world, with a population estimated up to 300,000 people. The seven-year rule of Archytas marked the apex of its development and recognition of its hegemony over other Greek colonies of southern Italy. During the Norman period, it became the capital of the Principality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
