Despite the limited surveying tools of the time, it is reported that no side is more than 8 inches different in length than another. The Sumerians represented the integers using cuneiform wedge patterns.
Hieroglyphics for numbers were introduced around 3000 BCE.
THE PLAGUE IN ATHENS DURING THE PELOPONNESIAN WAR The plague in Athens was caused by the war strategy of Pericles. The curve may be used for dividing an angle into any number of equal parts.
His strategy was to bring all citizens from the surrounding area into Athens and let the Spartans have control of the outlying area. It appears that this was the first curve in in mathematics that was not either a straight line or part of a circle.
The axle rotated against the bed of the vehicle and this probably helped round the axles.
The Great Pyramid was built by the Egyptian pharaoh Khufu (also known as Cheops) of the Fourth Dynasty around the year 2500 BCE to serve as a tomb for when he died.
The site was first prepared by leveling the surface and then blocks of stone were transported and placed.
It was finished with an outer casing which was used to smooth the surface. Some interesting data: it is 756 feet long on each side, 480 feet high and is composed of approximately 2,300,000 blocks of stone, each averaging 2 1/2 tons in weight. This is a positional number system based on sixty, rather than ten.
Wheeled vehicles first appeared in Mesopotamia (the region between the Tigris and the Euphrates Rivers ) around 3000 B. The wheels on the earliest vehicles were fixed to the axles rather than rotating around a hub.
The axles themselves were held in place with wooden pegs on each side of the axle.
Much of the early Greek arithmetic and geometry can be traced back to the Pythagoreans. He worked on the problems of squaring the circle and duplicating the cube. Among his accomplishments was to bring the ordinary citizen into the Athenian democracy.
While working on the problem of squaring the circle, he was able to find the areas of lunes. E.) Hippocrates of Cos is known to us as the Father of Western Medicine and he is credited with originating the Hippocratic Oath that all doctors take upon completing their studies. He was a gifted orator as was documented by the historian Thycidides.
An interesting account of his quadrature (squaring) of the lune can be found in and although his work is no longer extant it has been reported by later Greek writers to have contained much of what Euclid included in his first two books of the Elements, which appeared about 120 years later. Pericles was credited with creating the mighty Athenian empire.
