Inventions of Archimedes
Archimedes area of expertise was inventions and coming up with great ideas. He was a very smart person, and had invented some useful inventions for human kind for what is still used today. BC. He was a physicist, engineer, inventor, astronomer and a Greek mathematician. Archimedes is one of the greatest math mathematicians of all time. He has been given credit for the invention of the lever even though it was used thousand of years before his time despite the fact that he did not invent it. He only gave an explanation of the principal involved in his work. Once He had made the statement “If I were to have a place to stand, I would be able to move the entire earth”. Another invention Archimedes had invented was the Archimedes screw. This invention helps to bring water from lower areas to higher grounds by a rotating screw inside a tube constantly. The water is forced out the tube even though the water is at lower ground. This invention is also used today. Also an interesting invention Archimedes invented was the Heat Ray. This was used to destroy enemy ships by catching a part of the ship on fire then having it burn all the way down. People have tested this invention out to see if it was true for example, in 1973 a Greek scientist Ioannis Sakkas but had failed. In 2006 the Mythbusters had tested out this invention but also failed, while in 2005 a group of students had a small flame on a wooden ship they made. Archimedes childhood

Archimedes was born in the seaport city of Syracuse, Sicily on c. 287 BC and since there are little records on his birth people don’t know very much about his childhood. He was related to King Hiero II, the ruler of Syracuse by “parallel lives” which was stated by Plutarch, a Greek historian. Apart from where Archimedes had lived, there is not very much information about his childhood....

...Archimedes Background/Upbringing
Archimedes was one of the most known and respected mathematicians of ancient Greece. He was born between the years of 290 and 280 BCE in Syracuse, Sicily which is currently known as Italy. His death took place in Syracuse, Sicily between the years of 212 and 211 BCE. In autumn of 212 or the spring of 211 Syracuse was taken over by Roman General Marcus Claudius Marcellus (Encyclopedia Britannica, n.d). It was during the cities take over that Archimedes was killed. There is rumors about what lead up to a Roman solider killing him. Some historians believe his death was due to Archimedes not willing to give up his mathematical diagrams of mirrors that would burn the Roman ships. The exact years of his birth and death are uncertain, but Greek historian John Tzetes believes he lived to be 75 years old (“Archimedes”, n.d). Archimedes father was named Phidias who was an astronomer. His mother’s name is unknown, but there is belief that Archimedes is related to the Ruler of Syracuse King Hiero II. There are currently not many documents of Archimedes upbringing. In fact there is only one record of his life that was written by his friend Heracleides. Unfortunately this biography was lost.

The Life of ArchimedesArchimedes was a Greek mathematician, a scientist, and a skilled inventor who was born around 287 B.C. in the seaport city of Syracuse, Sicily. It has been said that since his father was an astronomer, Archimedes inherited his fathers interest for mathematics, science, and inventions, however his biggest interest was in Geometry. In his lifetime not only was he was able to create a ton of helpful inventions, he also discovered how to find the volume of a sphere, determine the exact value of Pi, created the Principle of Buoyancy, and also created Scientific Notation (Powers of Ten). He took great pride in his work and there were times where he became so in depth with his work, he often forgot to bathe or eat and some would say his real hunger was to learn! Archimedes became famous for many things and he has come to be known as one of the biggest contributors to today's mathematics. He was often called “the wise one”, “the master”, and also “the great geometer” by his peers.
One of Archimedes' many accomplishments was “The Archimedes Screw” which was created to fulfill the needs of his king and good friend, King Hieron II. Archimedes was his military adviser and his job was to create useful tools as well as build things. One day King Hieron commissioned Archimedes to design a luxury ship of sorts which came to be known as “The...

...Archimedes’ Principle
Abstract
The purpose of this experiment was to investigate the Archimedes’ Principle for objects of different densities and use the principle to determine the density of a golf ball. The weight of rubber stopper and the wood cube were measured in the air by using the force sensor. When the objects were submerged in the water, the apparent weight of the objects was measure with the force sensor and the volume of the displaced water were measure with a graduated cylinder. These same procedure was used to obtain weight and apparent weight of the golf ball. The weight of the displaced water when the rubber stopper was submerged was 1.94 N. Buoyant force obtained was 1.96 N and 2.14 N with a percent discrepancy of 0.97% and 9.30% respectively. The weight of the displaced water by the object was 1.14 N. The buoyant force was 1.14 N and 1.24 N with a percent discrepancy of 0.0% and 8.39%, respectively. The density of the golf ball was 1201.50 kg/m3. The theoretical values of the golf ball was 1130 kg/m3. The percent discrepancy was 6.19%. The percent discrepancy between the predicted mass and the experimental mass of the beaker, water, and golf ball was 0.056% which indicates an accurate prediction. The objective of the experiment was successfully met, investigators were able to confirm that the object is buoyed up by a force equal to the weight of the water displaced by the object.

Archimedes Principle
-------------------------------------------------
Abstract:
* -------------------------------------------------
Sophomore students from Occupational Therapy in De La Salle Health Sciences Institute had conducted an experiment concerning Archimedes’ Principle to determine the density of solids and liquids usingArchimedes’ Principle. For the density of solids, they had made use of spring balance to measure the mass of the metal samples, which were tied via string, in air and when immersed inside a 2000mL beaker, where H2O lies. They had computed the density of each sample metal using the formula: ϱs = maϱw / ma - mw and computed a percentage error. As for the density of liquids, they had filled a graduated cylinder with 250mL liquid sample and had immersed a hydrometer. They had immersed a sample metal in the liquid sample and had measured its mass in air and beneath the liquid. They also had measured the volume of displaced liquid as the metal sample is immersed in the liquid and had computed the density using the formula: ϱL = WaWL / gV, and the percentage error after. They had been successful to support the theory of Archimedes and had came up with percentage error ranging from 5.76% to 9.91%.

...the water back into the sea.
It is unclear whether or not Archimedes designed this pump for the use on the ship but it is widely thought that the great mathematician invented such a tool to help Egyptians maneuver water from lower land to higher for watering the fields.
This invention has survived the winds of time and is still used today,most recently applyed at draining parts of land in the Netherlands that were underwater and also for stableizing the tower of Pisa in 2001.
According to information from Arab sources noted by A.Favaro, Archimedes probably made another trip to Egypt, during which he designed and executed several projects on water management of the river Nile, projects which are reported by Arab authors. Beyond these signs though,essentially we know that Archimedes travelled to Alexandria only once and no other time, since, according to all sources the greatest part of his life he spent in his hometown of Syracuse, where he came up with all his theoretical or mechanical discoveries.
On the return to his homeland Archimedes made another very important discovery.Hiero wanted a golden crown to be made for him so he asked a goldsmith and gave him 772 grams of gold with a mandate to fulfill his wish.And so, the goldsmith made the crown for the tyrant. But Hiero was worried that that the crown wasn't produced from just gold but had another material inside.
This is when Hiero,called...

..."Give me a lever long enough and a place to stand, and I will move the world."
Archimedes
By Alex Christopher
Archimedes was a mathematician, physicist, engineer, inventor and astronomer in ancient Greece. He was born in 287 BC and lived until 212 BC in Syracuse, Sicily where he lived his whole life, except for when he went to school. Archimedes father was an astronomer and the family was related to the king of Syracuse. His family had money so they were able to afford to send him to school. When he became a teenager, he studied in Alexandria, Egypt in school that was run by students of Euclid. Euclid was known as the father of geometry which helped Archimedes learn about how to calculate angles for his inventions. There is not a lot of information about Archimedes personal life, like whether he was married or had children. He was killed during the battle of Syracuse when the Romans invaded. Even though there were orders to not kill Archimedes, he was killed by a soldier who didn’t know him.
Archimedes made a lot of contributions and is considered one of the greatest mathematicians of all times. He invented machines to protect Syracuse, pulley systems, the Archimedean screw, the planetariums and Archimedes mirror. The Archimedes mirror is also called the Death Ray and is supposed to have caught passing Roman ships on fire during...

...Title:
Archimedes principle
Objective:
To use Archimedes Principle to determine the density of an object more dense than water.
Introduction:
Archimedes' principle is a law of physics stating that the upward force (buoyancy) exerted on a body immersed in a fluid is equal to the weight of the amount of fluid the body displaces. In other words, an immersed object is buoyed up by a force equal to the weight of the fluid it actually displaces. Hence, the buoyant force on a submerged object is the same with the weight of the fluid displaced. The weight of the displaced fluid is directly proportional to the volume of the displaced fluid (if the surrounding fluid is of uniform density). In simple terms, the principle states that the buoyant force on an object is going to be equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational constant, g. Thus, among completely submerged objects with equal masses, objects with greater volume have greater buoyancy. In this experiment, to calculate the density, we can use two methods:direct and indirect measurement. Direct measurement is used to calculate the mass and volume of object eg. magnet bar, pendulum bob and marble by using vernier calipers. By finding the density, we could determine the specific gravity of the object(the ratio of its density versus that of water, ρwater=1000kg/m3).
