The life and discoveries of archimedes of syracuse

Little is known for sure of his life, and many of the stories and anecdotes about him were written long after his death by the historians of ancient Rome.

The device consists of a screw mechanism inside a hollow casing. When the screw is rotated, either by windmill or manual labour, the bottom end of the screw scoops water, then moves it through the casing against gravity until it escapes through the last thread to reach irrigation canals.

The New York Times, June 18, Today, the same principle is used in modern machinery for drainage and irrigation, and also in some types of high-speed tools. It can also be applied for handling light, loose materials such as grain, sand, and ashes.

Of course, these look more impressive. Each screw is powered by a hp diesel engine and can pump up togallons per minute. The SS Archimedes was a ship named after the great inventor, which was the first steamship to come with a screw propeller. One of eight ft. Popular Mechanics Aprilpage Painted by Giulio Parigi in the years Throughout his career as an inventor, Archimedes would frequently be commissioned by the rulers of Syracuse to invent war machines to protect their fair city.

The story is extremely controversial, and even to this day historians and engineers alike debate whether this is a fact or myth. When Marcellus [The Roman General] had placed the ships a bow shot off, the old man [Archimedes] constructed a sort of hexagonal mirror.

He placed at proper distances from the mirror other smaller mirrors of the same kind, which were moved by means of their hinges and certain plates of metal.

He placed it amid the rays of the sun at noon, both in summer and winter. The rays being reflected by this, a frightful fiery kindling was excited on the ships, and it reduced them to ashes, from the distance of a bow shot. Thus the old man baffled Marcellus, by means of his inventions.

The ability of mirrors to concentrate the sun and obtain high temperatures is no myth, as any kid who used a magnifying glass to burn scraps can attest.

This year, Morocco opened the largest concentrated solar power CSP plant in the world which will generate enough electricity to power the homes of one million people. CSP plants typically use 12m high parabolic mirrors that reflect sunlight onto pipework that contains a heat transfer fluid HTFtypically thermal oil.

The HTF is then used to heat steam in a standard turbine generator.

Apparently, in a Greek scientist, Dr. Jamie Hyneman, who was stationed on the mock boat for the duration of the experiment, did say that he could barely see, however. The king himself weighed the gold and gave the goldsmith the material to turn it into a piece of art.

At the appointed day, the goldsmith presented his masterpiece — a gold crown shaped like a laurel wreath, exactly as the king ordered. When it was weighed, it had exactly the same mass as measured earlier. The king was pleased, but only days before the temple ceremony, he heard rumors that the goldsmith had cheated him and given him a crown not of pure gold, but of gold that had silver mixed with it.

Hiero believed there was only one man in Syracuse capable of discovering the truth and solving his problem — his cousin, Archimedes, a young man of 22 who already distinguished himself in the fair city for his work in mathematics, physics and engineering.

When faced with the challenge, Archimedes devised a clever science experiment to get to the bottom of things, but not until after thoroughly pondering the situation. Legend has it that Archimedes was thinking about the golden crown while bathing in the public baths one day.

As he began to enter a cold bathtub for his final dip, he noticed water started dripping on the sides. As he continued to lower his body into the bath, even more water ran out over the sides of the tub. I have found it! He knew that if the crown was pure gold, its volume would be the same as that of the lump of gold which he had made sure weighed the same as the crownregardless of shape, and it would displace the same amount of water as the gold.

If the goldsmith had indeed cheated and replaced some of the gold with silver, then the volume of gold and silver would be greater, and thus the crown would displace more water. According to Vitruvius, Archimedes used this method and found the goldsmith had indeed cheated. As far back asGalileo wrote a short treatise called La Bilancetta, or The Little Balance, in which he argued this method could not be work because the differences in gold and silver volumes are too small.

Instead, he suggested Archimedes used a similar, but more crafty technique. In short, Archimedes probably suspended the gold crown on one end of a scale, and a lump of gold of equal mass on the other end.

The scale would have been then submerged in water, with both contents still on the ends of the scale. Since a body immersed in water is buoyed up by a force equal to the weight of the water displaced by the body, the denser body, which has a smaller volume for the same weight, would sink lower in the water than the less dense one.Archimedes, (born c.

bce, Syracuse, Sicily [Italy]—died / bce, Syracuse), the most-famous mathematician and inventor in ancient Greece. Archimedes is especially important for his discovery of the relation between the surface and volume of a sphere and its circumscribing cylinder.

The life of Archimedes impacted many people of his time because his inventions brought a new level to ancient warfare. He was also well known for being a mathematician and for his scientific writings, many of which still survive today.

Archimedes was born in Syracuse, Sicily, and . Archimedes is considered one of the greatest mathematicians of all time. He is also famed for his inventions and for the colorful—though unproven—ways he is believed to have made them.

Little is known about Archimedes's life. He probably was born in the seaport city of Syracuse, a Greek. The life and work of the ancient Greek mathematician, Archimedes, including Archimedes' life and studies, the library at Alexandria, Archimedes Principal, Archimedes relationship with Hieron, the siege of Syracuse, geometric studies, Archimedes screw and Archimedes death and tomb.

Archimedes lived in Syracuse almost all his life but he went to school in Alexandria, which was the intellectual capital of the world at the time. Archimedes was sent off to school and studied at the school of Euclid, the famous mathematician.

Archimedes of Syracuse was an outstanding ancient Greek mathematician, inventor, physicist, engineer and also an astronomer. Although not much is known about his life, he is considered as one of the most eminent scientists Place Of Birth: Syracuse.
