In ancient times, Samos, although small, played a really significant role in culture and politics not only for the region of Ionia, but for the entire ancient Greece. From the evidence that has been found, derives that human beings have lived on Samos since the 3rd millenium BC, if not earlier. Its favourable position at the sea crossroad that link central Greece with East played a significant role for its development. Several megatheriums and other rare species of the prehistorical era lived on this island. Bones that found the previous century decorate the show -cases of the paleontological museums of USA and Europe. Some of these paleontological findings are in the museum of Mytilinion of Samos. Bones from the Paleontological Museum of Mytilinion Samos Traces of the human race have been found at the Hill of Castro from the late Neolithic era (fourth millennium B.C.). The first inhabitants belong to the Pelasgic tribes that spread the worship of Hera. According to mythology, Hera was born at the banks of the rive Imvras and was considered as the protector of Samos. Thus, her sacred bird, the peacock, often appeared on currency and escutcheons of the hegemony of Samos later.

Aristarchus was born on the island of Samos in 310 B.C. and died in 250 B.C. He was both a mathematician and an astronomer. Aristarchus was a student of Strato Lampuscus, who was head of Aristotle’s Lyceum in Athens. However, Aristarchus did not study in Athens instead he studied with Strato in Alexandria, where Strato became the head of the Alexandria Lyceum in 287 B.C. Aristarchus also belonged to the Pythagorean School of thought. In the world of geometers, Aristarchus succeeded Euclid and preceded Archimedes, and in 288 or 287 B.C. he followed Theophrastus as the head of the Peripatetic School established by Aristotle. Aristarchus’ only existing treatise is "On the Sizes and Distances of the Sun and Moon", where as you would guess, he measured the sizes and distances of the Sun and Moon by using Geometry. His geometry was accurate, but he obtained inaccurate values due to faulty observations. This work did not contain anything on his proposition of a heliocentric (sun-centered) universe, but the great mass of the sun probably lead him to the realization of his discovery. He declared that the Earth rotates and revolves around the sun, and for this was indicted for impiety by Cleanthes the Stoic. Aristarchus’ book on the planetary system with the Sun in the center did not survive, and we know of it only through references to its content, chiefly by Archimedes. However, Archimedes only made reference to the works of Aristarchus to refute them. Aristarchus had no followers in his generation, or the next generation. But about a century after Aristarchus, Seleucus, a Chaldean of Seleucia on the Tigris, who lived and wrote about the year 150 B.C., adopted the teaching of Aristarchus. Seleucus attributed the ocean’s tides to the stirring of air by the rotation of the Earth and it’s interaction with the revolution of the moon. Hipparchus was a contemporary of Seleucus. Hipparchus is thought to be the greatest astronomer of antiquity, but he rejected the heliocentric system of Aristarchus, and this he did not on a religious ground, but on a scientific one. A system with the Sun in the center of circular orbits could not account for the peculiarities in the visible motions of the planets, but the theory of epicycles could, and this theory had the Earth immobile in the center of the universe. Aristarchus is often referred to as the Copernicus of antiquity, as he devised a heliocentric universe far before the theory proposed by Copernicus.

Naam: Wachtwoord: Bronvermelding Sitemap Over deze site Overige Een groot meetlint? De Grieken hadden niet de beschikking over geavanceerde meetapparatuur. Ze hadden geen telescopen, laat staan hubbletelescopen, tot hun beschikking. Toch slaagden ze erin om met bewonderenswaardige precisie de afstand tot de maan en de grootte van de aarde te berekenen. Gewoon met een 'beetje' wiskundige inzicht... Aristarchus Aristarchus van Samos (310 - 230 v.C.) is bekend van twee zaken: hij heeft de afstand en grootte van de zon en de maan proberen te berekenen en hij verklaarde dat het zonnestelsel heliocentrisch is. Dat laatste bespreken we elders op onze site. Laten we eerst naar Aristarchus' berekeningen kijken. Aristarchus bedacht een briljante manier om de afstand van de aarde tot de maan te berekenen. Stel dat je een kwartje voor je ogen houdt en je kijkt recht in de zon. Wat is dan de afstand tussen jouw oog en het kwartje als het kwartje de zon precies bedekt? Het antwoord is dan 108 keer de diameter van het kwartje. Je kunt het met alle soorten cirkelvormige objecten proberen het antwoord is altijd de diameter van het voorwerp. In die tijd werd de diameter van de aarde door de Grieken geschat op 12.000 kilometer. Dit betekent dat de aarde een kegelvormige schaduw heeft van 108 * 12.000 = 1.296.000 km. Een maansverduistering, zo wist Aristarchus, wordt veroorzaakt door de schaduw van de aarde, dus is de maan minder dan 1,3 miljoen kilometer van de aarde verwijderd.

Greek Science after Aristotle Michael Fowler UVa Physics Index of Lectures and Overview of the Course Link to Previous Lecture Strato As we mentioned before, Aristotle's analysis of motion was criticized by Strato (who died around 268 B.C., he is sometimes called Straton), known as "the Physicist" who was the third director of the Lyceum after Aristotle (the founder) and Theophrastus, who was mainly a botanist. Strato's career was curiously parallel to Aristotle's. Recall Aristotle spent twenty years at Plato's academy before going to Macedonia to be tutor to Alexander, after which Aristotle came back to Athens to found his own "university", the Lyceum. A few years later, Alexander conquered most of the known world, dividing it into regions with his old friends in charge. In particular, he had his boyhood friend Ptolemy in charge of Egypt, where Alexander founded the new city of Alexandria. Now Strato, after a period of study at the Lyceum, was hired by Ptolemy to tutor his son Ptolemy II Philadelphus (as he became known) in Alexandria. Subsequently Strato returned to Athens where he was in charge of the Lyceum for almost twenty years, until his death. Strato, like Aristotle, believed in close observation of natural phenomena, but in our particular field of interest here, the study of motion, he observed much more carefully than Aristotle, and realized that falling bodies usually accelerate. He made two important points: rainwater pouring off a corner of a roof is clearly moving faster when it hits the ground than it was when it left the roof, because a continuous stream can be seen to break into drops which then become spread further apart as they fall towards the ground. His second point was that if you drop something to the ground, it lands with a bigger thud if you drop it from a greater height: compare, say, a three foot drop with a one inch drop. One is forced to conclude that falling objects do

THE LOST KNOWLEDGE OF THE GREEKS During the first decade of the 16th century when Copernicus was still forming his astronomical hypotheses, he read the works of many Greek authors and found that heliocentric ideas had already been propounded. He mentions in his work some of those Greek mathematician-astronomers who held distinctly different views of the celestial system from that of Aristotle and Ptolemy, although not necessarily heliocentric, such as Philolaus, Hicetus, Ecphantus, and Heraclides ("On the Revolutions of the Celestial Spheres", Book One). Indeed, the geocentric theories were not the only systems known to the Greeks, nor even at times the most accepted. Between the sixth and fourth century B.C., there was a philosophical society known as the Pythagorean society in Greece. Pythagoras of Samos (c. 582-500 B.C.), founder of the society, traveled extensively in his youth by way of the sea to the East as well as to Egypt, and not only accumulated a wealth of knowledge from different corners of the Earth but also obtained a unique perspective that was possible only for the celestial navigator-businessmen of the time, i.e., the sphericity of the Earth. Astronomy and mathematics, particularly trigonometry, originated to a great measure among those celestial navigator-businessmen of antiquity whose survival almost entirely depended upon knowing the relative positions and movements of the celestial bodies. Furthermore, while traveling across the sea by observing the movements of the celestial spheres, it became revealingly clear to them that the Earth was a spherical entity. (Around 200 B.C., three hundred years after Pythagoras, Phoenician navigator-businessmen circumnavigated the Earth for the first time in recorded history and proved that the Earth was indeed spherical, preceding Magellan by more than 1700 years.)
