Fractals, Chaos, And Music archytas of tarentum, a Pythagorean mathematician who lived around 400350 BC, waseven able to work out the relationships between notes in the enharmonic scale http://www.geocities.com/SoHo/Square/7921/fmusic.html
Extractions: Many relations have been discovered in recent years between fractals and music. This paper will cover some of the research that has been done on these relations, including some of the controversies over conflicting discoveries. It will show how some artists are currently using fractals to generate the basic melodies in their compositions. A few computer programs which can be used to generate these melodies will be discussed. This paper will also examine possible practical uses for software which can be used to hear patterns in fractals. The algorithms behind the music-generating algorithms will be discussed, as well as some of the basic relations between mathematics and music. Some of the work of music theorist Joseph Schillinger, whose ideas in the 1920's and 1930's about generating music by recursive and chaotic means were far ahead of their time, will also be covered. The mathematical study of music is certainly nothing new, dating back to ancient Greece. Around the 5th century BC, the Pythagoreans formulated a scientific approach to music, expressing musical intervals as numeric proportions. This was probably done by observing the tones produced by plucked strings of different lengths; for example, the tone produced by a string held at the middle is an octave higher than that of the whole string. They went on to calculate the intervals for several different scales, including the chromatic and diatonic scales. Archytas of Tarentum, a Pythagorean mathematician who lived around 400-350 BC, was even able to work out the relationships between notes in the enharmonic scale, which includes quarter tones.

Eudoxus Eudoxus was born in 408 BC in Cnidus. He was a Greek geometer and astronomer. Eudoxusstudied at Plato's Academy and was a student of archytas of tarentum. http://www.angelfire.com/ca5/ancientgreecescience/eudoxus
Extractions: Eudoxus was born in 408 B.C. in Cnidus. He was a Greek geometer and astronomer. Eudoxus studied at Plato's Academy and was a student of Archytas of Tarentum. He spent over a year in Egypt and then, on his return, established a school that competed with Plato. There is ample evidence to suggest that Eudoxus had little respect for Plato's analytic ability. Eudoxus proposed a heliocentric system for the solar system; a very important contribution. Other important contributions were to the theory of proportion, where he made a definition of equal ratios similar to cross multiplying, and early work on integration with the theory of exhaustion. Eudoxus also devised a theory of planets carried on glassy spheres that were nested around the Earth in mountings like compass gimbals: rotations on these explained observed motions. The kampyle curve was studied by Eudoxus also in relation to the classical problem of duplication of the cube. Eudoxus found formulas for measuring pyramids cones and cylinders. Books V and XII of Euclid's Elements are attributed to Eudoxus by some experts. In 355 B.C. Eudoxus died in Cnidus.
Plutarch According to such principles Pericles regulated his life; so did likewisearchytas of tarentum and Dion the Syracusan and Epaminondas the Theban. http://home.uchicago.edu/~ahkissel/plutarch.html
Extractions: Adam Kissel (using Charles William Super's tr., Plutarch on Education (C. W. Bardeen: Syracuse, N.Y., 1910)) "The Education of Boys" (ps.-Plutarch) We may remark in general terms regarding virtue what we are accustomed to say concerning the arts and sciences, namely, that three factors are essential to the formation of a well rounded character: phusis logos , and ethos . By instruction I understand the acquisition and imparting of knowledge; by ethos . Natural endowments are inborn; progress is a matter of education; application, of (exercise); while the highest excellence is the result of all combined. In so far as any of these is wanting, is necessarily defective. Natural endowments without education are blind; education, where there are no natural endowments, is inefficacious; and practice apart from both is incomplete and must fail of its end. In confirmation of these views I might say that the three combined and cooperated in the psychic powers of the men of glorious memory such as Pythagoras and Socrates and Plato and all who have won imperishable renown. Fortunate and favored of the gods is every one upon whom the gods have bestowed all these gifts. If any one thinks that lack of natural endowments can not be supplied by suitable instruction and practice in virtue he is very much, yes, altogether mistaken. For disuse destroys the best natural endowments while improves even weak ones. (49-50)

The Earlier History Of Powered Flight Another tale recounts the invention of a Greek named archytas of tarentum whowas said to have made a wooden bird about four hundred years before Christ. http://www.centennialofflight.gov/essay/Prehistory/earliest_flight/PH1.htm
Extractions: The Earliest Efforts at Flight In Greek mythology, Icarus flew too close to the sun Other legends about flight abound. Another early one tells of King Bladud, who ruled in Britain in the ninth century B.C.E. Bladud supposedly constructed a pair of wings with which he proposed to fly. But, according to the monk Geoffrey of Monmouth in a history of the British kings, Bladud was dashed to pieces as he landed on top of the Temple of Apollo in the town of Trinovantum. Another tale recounts the invention of a Greek named Archytas of Tarentum who was said to have made a wooden bird about four hundred years before Christ. This bird was powered by steam and supposedly flew about 50 feet (15 meters). "Flight" of Simon the Magician in Roman times Earlier, in 1010, a monk in Malmsesbury, England, attached artificial wings to his body and jumped from the top of his abbey to glide to only two broken legs upon landing. Other tower jumpers suffered death or injuries, while a few achieved some partial success with their glides. In fifteenth-century Italy, the brilliant Italian artist, scientist, and engineer Leonardo da Vinci, who understood some of the basic principles of flight as early as the 1480s, was the first to seriously study aerodynamics. He examined the way birds flew and sketched their wings and muscles in a flying position. His notebooks were filled with drawings and descriptions of birds in flight and with models that had wings like birds. Unfortunately, his ornithopter and helicopter designs could never have left the ground with them. He, and others of his time, failed to realize that human beings lacked the necessary muscle power to imitate bird flight with flapping wings. His works were rediscovered in the 19th century and had little or no influence on the history of flight technology.
Plato Plato did not expect the plan to succeed but because both Dion andarchytas of tarentum believed in the plan then Plato agreed. http://www.crystalinks.com/plato.html
Extractions: Plato is probably one of the greatest philosophers of all times, if not the greatest. Plato was born to an aristocratic family in Athens. His father, Ariston, was believed to have descended from the early kings of Athens. Perictione, his mother, was distantly related to the 6th-century B.C. lawmaker Solon. When Plato was a child, his father died, and his mother married Pyrilampes, who was an associate of the statesman Pericles. Plato's original name was Aristocles, but in his school days he received the nickname Platon (meaning "broad" ) because of his broad shoulders. It was mostly in Pyrilampes' house that Plato was brought up. Aristotle writes that when Plato was a young man he studied under Cratylus who was a student of Heracleitus, famed for his cosmology which is based on fire being the basic material of the universe. It almost certain that Plato became friends with Socrates when he was young, for Plato's mother's brother Charmides was a close friend of Socrates. The Peloponnesian War was fought between Athens and Sparta between 431 BC and 404 BC.

Scipio: Laelius: I think so, too, but yet it is impossible to dispatch the other branches of the question, if you leave this primary point undetermined. Scipio: We must, then, I suppose, imitate Aratus, who, when he prepared himself to treat of great things, thought himself in duty bound to begin with Jupiter. Laelius: Why Jupiter? And what is there in this discussion which resembles that poem? Scipio: Why, it serves to teach us that we cannot better commence our investigations than by invoking him whom, with one voice, both learned and unlearned extol as the universal king of all gods and men. Laelius: How so? Scipio: Do you, then, believe in nothing which is not before your eyes? Whether these ideas have been established by the chiefs of states for the benefit of society, that there might be believed to exist one Universal Monarch in heaven, at whose nod (as Homer expresses it) all Olympus trembles, and that he might be accounted both king and father of all creatures; for there is great authority, and there are many witnesses, if you choose to call all many, who attest that all nations have unanimously recognized, by the decrees of their chiefs, that nothing is better than a king, since they think that all the gods are governed by the divine power of one sovereign; or if we suspect that this opinion rests on the error of the ignorant, and should be classed among the fables, let us listen to those universal testimonies of erudite men, who have, as it were, seen with their eyes those things to the knowledge of which we can hardly attain by report.

Extractions: Three geometric construction problems from antiquity puzzled mathematicians for centuries: the trisection of an angle, squaring the circle, and duplicating the cube. Are these constructions impossible? Whether these problems are possible or impossible depends on the construction "rules" you follow. In the time of Euclid, the rules for constructing these and other geometric figures allowed the use of only an unmarked straightedge and a collapsible compass. No markings for measuring were permitted on the straightedge (ruler), and the compass could not hold a setting, so it had to be thought of as collapsing when it was not in the process of actually drawing a part of a circle. Following these rules, the first two problems were proved impossible by Wantzel in 1837, although their impossibility was already known to Gauss around 1800. The third problem was proved to be impossible by Lindemann in 1882.

Extractions: Robots are not new. They have been around for centuries in various forms. Here's a brief overview of the development of both robots and computers. 400 BC Philosopher and mathematician Archytas of Tarentum built a wooden dove that could flap its wings and fly. Early 16th Century Hans Bullmann creates the first androids - simulated people that can play musical instruments for the delight of paying customers. In his laboratory at Nuremburg, scholar Johann Müller, aka Regiomontanus, is reputed to have created an iron fly and an artificial eagle, both of which could take to the air. In England, John Dee creates a wooden beetle that can fly for an undergraduate production of Aristophanes' Pax. At the Heilbrunn chateau in Germany, a mechanical theatre is created featuring 119 animated figures that perform a play about village life to the accompaniment of a water-powered organ. While training as a Jesuit, Jacques Vaucanson creates flying angels which cause him to be thrown out of the order.

Extractions: Power: The Final Ingredient page 1 The earliest recorded use of power to make objects fly was during the classic Greek civilization. About 500 B.C. Heron of Alexandria harnessed steam power when he constructed a rotating boiler with four vertical vents. Some fifty years later Archytas of Tarentum used a steam jet to launch a wooden bird. But it was not until the onset of the Industrial Revolution in England at the beginning of the 18th century that the steam engine became mass-produced and less expensive. Cayley himself had in 1837 designed a steam engine to power the propellers of a streamlined balloon - that is, he had foreshadowed the airship as well as the aeroplane. But he was dissatisfied with the design, which would pass water through a cooled pipe in such a way as to convert it to steam in a single pass. He was generally frustrated by the massive weight of the engines used to propel land and sea vehicles, and stressed the need for lightness of material and fuel. "It is proper to notice the probability that exists of using the expansion of air, by the sudden expansion of inflammable powders or liquids ... an engine of this sort might be produced by a gas-tight apparatus and by firing the inflammable air generated with a due portion of air under a piston." Cayley was anticipating the internal combustion engine, but it would not arrive until after his death. Orville and Wilbur Wright became interested in flight as boys in Ohio when their father gave them a rubber band powered toy glider, a recent invention of Alphonse Penaud. Although the brothers did not go onto higher education they were curious, creative and mechanically inclined. As adolescents they had designed and built their own printing press and published a weekly newspaper. When bicycling became popular in the 1890's they took advantage of the "mania" and ran a successful bicycle repair shop. They made so much money repairing bikes they went on to design and manufacture their own bicycles and, of course, added mechanical innovations they had designed.

Extractions: by Anne Hance T he ancient Chinese propounded the notion during the first century AD, that the sun, moon and stars float freely in space. This notion, while an improvement over earlier ideas, is not acceptable in light of our modern understanding of bodies in space. But they correctly recognized that water particles float in the air and, as part of a water cycle, sink down to earth as rain to replenish lakes, rivers and oceans. S ince a fluid is any substance that takes the shape of any vessel containing it, air and water are both 'fluids'. The physical and chemical properties of air and water have enabled the development of many forms of life ever since life began on this planet. But the purposeful study of these properties had to wait until sentient beings paid deliberate attention to them. O f course, prehistoric peoples recognized that some things would float on water and, without the need for any understanding of science to explain this phenomenon, they built rafts and boats. Experience, rather than a formalized knowledge of 'science', taught them how to take advantage of the physical properties of water and the materials with which they built their craft. L earning to take advantage of the physical properties of air was historically a much slower process. From earliest times, people watched birds and insects use the fluid nature of air to enable them to fly. People could not fly and so they invented things that could. Kites, which take advantage of air currents and wind to enable them to swim in the air, are thought to have been invented by the Greek scientist Archytas of Tarentum in the fourth century BC.

Extractions: though nothing could be conceived more delightful if he had but someone to tell what he had seen. I am very lucky to have a job which allows me to spend as much time as I want reading and thinking about chemistry. My goal, which I pursue in my general chemistry and inorganic chemistry courses, is to help my students understand chemistry so that they can get as much pleasure out of it as I do. Chemistry is the most wonderful, but also the most difficult, science to learn. In the laboratory chemists watch pieces of red metal dissolve in a colorless liquid to produce a blue liquid and a poisonous red gas. But we try to understand what we see by using a very abstract language to discuss things atoms, molecules, ions, and electrons which we can't see. I think the only way to make the gigantic intellectual leap between chemistry lab-world and the chemists' mind-world is by seeing, and then talking about, experiments which illustrate chemical ideas. I am very interested in designing classroom experiments, not just demonstrations, which help my students understand chemistry. As coordinator of the general chemistry program I am also responsible for developing experiments for our general chemistry laboratory. I've put together a pamphlet
