Extractions: The Democratic foundation established by the ancient Greeks Abstract: Our integrated project blends the subjects of math and history. Since two of our group members never bothered to show up these are the only two subjects we will be covering, with the two history majors focusing on religion and government respectively. The math portion will focus on famous Greek mathematicians. With the help of a special education major, we will alter the plan to cater to the needs of special needs students. I plan to use the week to explain how the ancient Greeks introduced a democratic form of government. This was a revolutionary form of rule in a world of dictators and tyrants. Throughout the week the class will learn about the origins of Greek democracy and its prominent figures. We will then compare and contrast the Greek form of democracy to the one used in our own government. We will also be discussing the possible reasons why democracy failed in Greece and if it seems possible for the United States to suffer the same fate. Names and Majors of the Team Members: Subjects Integrated: Objectives: Upon completion of this lesson, participating students will be able to note five key similarities between the ancient Greek democracy and the democracy of the United States.

Extractions: by John H. Lienhard Click here for audio of Episode 308. Today, we look at the first and last wonder of the world. The University of Houston's College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them. W e use the words "Eighth Wonder of the World" to name each new engineering marvel that comes down the road bridges, ships, and rockets. Maybe it's time to look back at the original Wonders. The 2nd-century BC Hellenistic engineer Philon of Byzantium wrote a tract called De Septem Orbis Spectaculis , literally, Of the Seven Spectacles of the World . He listed: The Lighthouse at Alexandria The Great Pyramid of Cheops So the Seven Wonders of the Ancient World are correctly those and those alone. They were marvels, of course. The great 150-foot bronze Colossus standing astride the jetties of Rhodes must have been daunting indeed. Yet Philon's list did by no means include the definitive great works for all time. They were the seven grandest works that he could identify in 150 BC. The Colossus lasted only 56 years before it was brought down by an earthquake. All Philon actually saw of it was bronze rubble.

Ancient Fortifications And Artillery Hero of Alexandria and philon of byzantium (both 3 rd century BC) left behind writingsabout catapult design and construction that have survived to this day. http://www.dragonridge.com/stories/Ancient_Fortification_Artillery.html
Extractions: A Survey of Ancient Fortification and Artillery Technology By Peter Lok Introduction Fortification walls were built to protect cities and towns. Defensive walls protected the defenders and kept attackers out at a large disadvantage. This development began an arms race that lasted until modern gun artillery was developed, effectively rendering large walls obsolete. After fortification walls were developed, the advantage lay with the defender. The best way to take a defensive wall is to not have to fight for it. The fifth column approach via spies, bribes, traitors, or guile is still the best approach. The weakest part of any security is always the human being in the chain. Phillip II of Macedon's favourite method of taking a city was to see if gold could bring the walls down. Using the Trojan Horse to gain entrance to Troy is the classic story of subterfuge when it was clear the city could not be taken by force. The Mongol's also used fear to cause some cities to throw open their gates without a fight after they made examples of cities that resisted their might. If other methods fail to take the defences, the attacker must either scale the wall, knock a hole in the wall or gate, or besiege the defenders until they surrendered. Siege artillery and engines were then developed to assist in penetrating these walls. Supplies from going in or out.

The best known are The first executive toy was probably a gadget designed by the great mathematician and engineer Philon of Byzantium (about 280 BC - about 220 BC). It was an octagon-shaped ink pot with openings on each side. One could turn the pot so that any face is on top and dip the pen in the opening, but the ink never ran out through the holes on other sides. The inkwell was suspended in the centre on a series of gimbals and remained stationary in spite of any rotation.

Extractions: The Transversal "AB" drawn through a given point "P" within a given angle "RCS" so that the sides of the angle intercept on the transversal a segment of minimum length has become known as the Philo Line (or Philon Line) of the point for the given angle. The line is name after Philon of Byzantium , an ancient Greek engineer. This problem was devised by Philo as a reduction to the duplication of the cube problem, and because of this link to this famous problem, it has excited interest over the ages.

Sem dúvida nenhuma, os avanços tecnológicos conseguidos após quase 2.000 anos da Era Cristã, em todas as áreas onde o ser humano atua, pode ser considerado assombroso. Uma maravilha, até. Entretanto, sem contar com todo o arsenal tecnológico acumulado para se conseguir concretizar idéias que traduzem avanço, já no início da história o homem realizou obras que causariam igual assombro: as chamadas Maravilhas do Mundo ou Maravilhas da Antigüidade , na Foram os gregos, provavelmente entre os anos 150 e 120 a.C., os primeiros a listar os monumentos erigidos até então pelas mãos do homem que se destacavam pela sua grandeza, suntuosidade e magnitude. Chamaram o conjunto deles de "Ta hepta Thaemata", ou seja, "as sete coisas dignas de serem vistas" - as sete maravilhas do mundo. Apesar da lista ser grega, apenas uma das obras situava-se na Grécia: a

Extractions: Simple gears are straight toothed wheels. The teeth on helical gears and bevel gears are set at an angle and are thus able to transmit more power. The optimal curvature of the tooth flanks for the teeth to engage was calculated by Leonhard Euler in 1750. Aristoteles erwähnt Zahnräder bereits um 330 v. Chr.
