43. European Cultural Centre Of Delphi Two detailed descriptions of the instrument have survived, in texts by Vitruviusand heron of alexandria, but they concern primarily the mechanical device by http://www.culture.gr/2/23/232/e232012.html

European cultural Centre of Delphi The Ancient Hydraulis Index: [Historical particulars: antiquity] [Dissemination of the instrument: Rome and Byzantium] [Western Europe] [Reconstruction project] Historical particulars: antiquity T Dissemination of the instrument: Rome and Byzantium T he hydraulis spread very rapidly through the Hellenistic and later the Roman world, where it provided musical accompaniment for games in the forum and was the favourite instrument of Emperors such as Nero. Ancient references to the hydraulis and the many depictions of it on coins, vases and stone pillars which have come down to us reveal that the instrument was constructed in numerous types which varied in size and number of pipes. Little by little, the hydraulic mechanism was replaced by bellows and the hydraulis joined the family of wind instruments. As early as the first centuries AD, both types of instrument were in use. During the first Christian centuries, after the barbarian invasions of Europe, the instrument disappeared from the western part of what had been the Roman Empire, although in its blower-powered form it continued to exist in Byzantium. There is no evidence of hydraulically-powered instruments in Byzantium. In the Imperial court at Constantinople, the organ was a symbol of prestige and it played music during the visits of foreign guests in order to impress them. Constantine Porphyrogennetos (tenth century) formally established the organ in court protocol, and decreed that it was to play during specific ceremonies in the Great Palace and the Hippodrome.

44. Alexandria Doc. Alfred Chapuis. Three centuries later, heron of alexandria drew upa summary of the mechanical research carried out by his predecessors. http://miralabwww.unige.ch/subpages/automates/antiquite/alexandria.htm

Automata of Alexandria The Alexandrian School inherited from a long tradition dating back to the 6th century BC with Thales, Pythagorus and Euclid, who provided inspiration for the illustrious mechanists. Of the above, Ctesibius is generally considered to be the founder of the Mechanical School in Alexandria. He explored new areas, carried out research into wind instruments and the basic principles of mechanics, such as the elasticity of air, the incompressibility of water, and transmission and reduction ratio mechanisms. He is attributed with the invention of the suction and force pump and the hydraulic organ. Museum of automata, York (England) Philon of Byzantium worked on pneumatics, clepsydras, automata, incredible instruments, and war machines. His research into the nature of air, how it interacts with water and vacuum, the equilibrium of liquids in communicating vessels, and siphons, led him to create some extraordinary objects with neither screws nor springs, just levers and skillfully drilled tubes. Fountain with figure and animal by Philon of Byzantium. This was activated by water.

45. HydrauliqueGB in their castles. Since the time of heron of alexandria, the mechanismsdid not change and did not improve. Among the authors of http://miralabwww.unige.ch/subpages/automates/moyen_age/grottos.htm

"Fountain in full play" and "artificials grottoes": Hydraulic Automata Hydraulics, already used in antiquity for the embellissement of palaces, was also used, during the 15th century and probabley earlier in Italy, for the enjoyment of the rich lords in their castles. Since the time of Heron of Alexandria, the mechanisms did not change and did not improve. Among the authors of the 17th century inspired by alexandrines scientists, we can quote from Solomon of Caus, a French engineer. He dealt with the "Fountain in full play" and the "artificials grottoes". He published a work: "The Reasons of the moving forces with differents machines as well useful as pleasant" in which he applied in particular the principles of hydraulics. In his books, he described in particular, some apparatuses imitating the song of birds and hydraulic clocks (clepsydres);He spoke also about the installation of the " grottoes and fountains " and the construction of the organ whose oldest inventor is Heron of Alexandria. The operation is simple "water falling with force on the blade of a wheel, puts all the procession moving, while by different conduits it supplies the figurines of this scene with the water. "

DIOPHANTUS OF ALEXANDRIA(250 C.E.) 250 BC Number Theory, Algebra Diophantus worked during the middle of the 3rd century, is best known for his Arithmetica, a work on the theory of numbers. The Arithmetica is a collection of 130 problems giving numerical solutions of determinate equations (those with a unique solution) and interminate equations. The method for solving these equations is now known as Diophantine analysis. Diophantus was always satisfied with a rational solution and did not require a whole number. He did not deal in negative solutions and one solution was all he required. Most of the Arithmetica problems lead to quadratic equations. He also introduced an algebraic symbolism that used an abbreviation for the unknown. BEDE'S LIFE (673-735 C.E.)

Ballista Test Firing 4/17/99 The day had finally arrived! The ballista crew assembled at Anoka High School soccer field to try out the ballista for the first time. Th e f irst shot was done with the slider and sling drawn back only about halfway, just in case the shock of firing did any damage. The first shot went well, so the next shot was made a t 45 degrees for maximum range and power. Unfortunately, the piece of wood that stops the slider from sliding backwards when the trigger was released broke off when the slider struck it. The second shot flew 430 feet (134 yards). Also, some minor damage occurred to the engine. The hemp cord seizing the left loop of the sling to form the eye br oke. No big deal there. We noticed a piece of wood flying off to the left when the trigger was pulled, which also shows up in the photo to the left. As it turned out, the wood piece was the small piece of wood that was glued to the back of the left arm to prev e n t the arm from sliding inward in the cord bundle from the tension of the sling when it mov ed to the brace (undrawn) position.

49. Heron's Criterion heron of alexandria lived in the first century BC and contributed massivelyto mechanics, optics, and geometry. Today he is mainly http://www.math.ubc.ca/~hoek/Teaching/Heron/Herocrit.html

Heron's Criterion Part of the Geometry Primer for Mathematics 337 at the University of British Columbia. Heron of Alexandria lived in the first century BC and contributed massively to mechanics, optics, and geometry. Today he is mainly remembered for a remarkable way of computing the area of a triangle (Heron's Formula) namely as the square root of a four-dimensional volume! A bold stroke which we shall hide by jumping from shapes to numbers before we get to the famous formula. For the moment staying with shapes let us consider a triangle ABC decomposed as shown on the left by cutting along the angle bisectors and the perpendiculars dropped onto the sides from the centre of the inscribed circle. The resulting six wedges can then be arranged into a rectangular strip marked with a zig-zag pattern like so. First question: given a strip subdivided as on the right, with obtuse angles LAM and AMB, how can one tell (without taking it apart) that its pieces can be assembled into triangle as shown above? By the way, if angle AMB were not obtuse, the angles around M in the next diagram below would add to at most 180 degrees (see?), and there would no "crater" at M to fit the purple wedge and its twin. Likewise for LAM.

The dates of his birth and death are unknown; conjecture places them between the 2d cent. B.C. and the 3d cent. A.D. He is believed to have lived in Alexandria; although he wrote in Greek, his origin is uncertain. Several of his works survive either in Greek or in Latin translation. He wrote on the measurement of geometric figures, and a formula for finding the area of a triangle has been ascribed to him. Known for his study of mechanics and pneumatics, he invented many contrivances operated by water, steam, or compressed air; these include a fountain, a fire engine, siphons, and an engine in which the recoil of steam revolves a ball or a wheel. heron Herophilus Awards and Press Citing Fact Monster Lycos Worldwide Lycos Zone Privacy Statement
