Archimedes
Archimedes of Syracuse (Greek: Ἀρχιμήδης; c. 287 BC - c. 212 BC) was a Greek mathematician, physicist, engineer, inventor, and astronomer. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Among his advances in physics are the foundations of hydrostatics, statics and an explanation of the principle of the lever. He is credited with designing innovativemachines, including siege engines and the screw pump that bears his name. Modern experiments have tested claims that Archimedes designed machines capable of lifting attacking ships out of the water and setting ships on fire using an array of mirrors.[1]
Archimedes is generally considered to be the greatest mathematician of antiquity and one of the greatest of all time.[2][3] He used the method of exhaustion to calculate thearea under the arc of a parabola with the summation of an infinite series, and gave a remarkably accurate approximation of pi.[4] He also defined the spiral bearing his name, formulae for the volumes of surfaces of revolution and an ingenious system for expressing very large numbers.
Archimedes died during the Siege of Syracuse when he was killed by a Roman soldier despite orders that he should not be harmed. Cicero describes visiting the tomb of Archimedes, which was surmounted by a sphere inscribed within a cylinder. Archimedes had proven that the sphere has two thirds of the volume and surface area of the cylinder (including the bases of the latter), and regarded this as the greatest of his mathematical achievements.
Unlike his inventions, the mathematical writings of Archimedes were little known in antiquity. Mathematicians from Alexandria read and quoted him, but the first comprehensive compilation was not made until c. 530 AD by Isidore of Miletus, while commentaries on the works of Archimedes written by Eutocius in the sixth century AD opened them to wider readership for the first time. The relatively few copies of Archimedes' written work that survived through the Middle Ages were an influential source of ideas for scientists during the Renaissance,[5] while the discovery in 1906 of previously unknown works by Archimedes in the Archimedes Palimpsest has provided new insights into how he obtained mathematical results.[6
What is the role of the gods in Homer's epics?
During the Trojan war , in the book Iliad by Homer . The Greek gods and goddess took sides , some joined the Trojan side and and some sided the Greek. But as Zeus the head of the gods had strictly told them gods and goddess not to help in the war. But the goddess Athene requested the god Zeus , to let them guide them only. So as it was an arrow guided by Apollo hit Achilles in the anckle.
How did the geography of Greece differ from that of other ancient civilizations?
Greece was mountainous, and thus less than 20% of its land could be farmed for grains, although its climate was perfect for growing grapes (for wine), and olives (for olive oil).
In the Fertile Crescent and Egypt, it was hot and dry, but the land was flat. Major rivers in the Fertile Crescent provided for peoples' irrigation needs, and the Nile River also provided water and fertile soil because of its annual floods. These areas could easily grow surplus grain.
What is an oligarchic governmnen?
An oligarchic regime, also known more succinctly as an oligarchy, is any type of governing body that is answerable only to itself, and which is self perpetuating because it elects its own new members, as old members retire or die. The most familiar example is the politburo, in a country that is ruled by a communist dictatorship. Only the members of the politburo elect new members to the politburo; nobody else has any say in the matter. This is not like a hereditary monarchy, because it is not based on lineage. You do not have to be the son of a member of the politburo to be elected to the politburo. But then again, sometimes people do elect their relatives to positions of power. In North Korea, which at the present time is ruled by the 3rd generation of the Kim dynasty, the original oligarchy has turned into a monarchy in all but name. But communist China, which is not ruled by a descendant of Chairman Mao, is governed by a true oligarchy.
How do Greeks communicate with each other?
with Greek language of course... and pretty much the same way as other people around the world i guess, when the verbal doesnt work, they use sign / body language, lol...........
What are the Hippocrates principles?
Hippocrates was the first physician to treat diseases as the result of living habits rather than a punishment by the gods. The Hippocratic school believed that all illnesses were the result of an imbalance in the body of the four humours, fluids that when in health were naturally equal in amount. The four humours are, blood, black bile, yellow bile and phlegm. Hippocrates recommended that a physician was to always be tidy, honest, calm, understanding and serious.
What was the name of the famous poet during the Greek Dark Ages?
Homer was the only poet we might say was famous from the Greek Dark Ages.
The Greek Dark Ages began with the collapse of Mycenaean culture, and lasted about 400 years. The dates would be about 1200 to 800 BC.
Homer is sometimes dated to as early as 950 BC, and sometimes as late as about 750. That being the case, he is arguably from the Greek Dark Ages.

because nobody really knows what caused the changes between two periods in Greece history
What conflict brought city-states together?
In ancient times, the many different societies (usually organized as city-states) of Greek civilization were unified in times of stress or conflict, if not always unanimously. The greatest unifying conflict for the Greeks came from invasions by the Empire of Persia, whose incursions into the center of the Greek world in the 5th century BCE (or BC) were especially significant: it was only by banding together that the Greeks were able to repel the large-scale invasion by land and by sea.
The Persian War against the Persian Empire.
What caused the Parthenon's destruction?
what caused the destruction of the Parthenon was Turkey attacked Athens and it was destroyed by an explosion.
What geographical disadvantage did the athenians have in the war against Sparta?
They had turned their geographical disadvantages to their own favour by building the long walls from the city to their port. They could then defend themselves, supply themselves by sea and launch sea invasions against their enemies - all in their favour.
This allowed them to keep going for 27 years until the Persians gave the Peloponnesian League the money to field a fleet which destroyed the hitherto dominant Athenian one. Athens, then beseiged without supply or allied support, had to surrender.
Pentemychos - a pentagon - it had five angles where the seeds of the god Chronos were placed within the Earth in order for the cosmos to appear
What color did ancient Greece call the sky?
