Archimedes was born on 287 B.C in the seaside city of Syracuse. He was a celebrated Mathematician, Physicist, Engineer, Astronomer and Inventor. As a mathematician, Archimedes proved one of the most rigorous geometric theorems, including the area of a circle, surface area and volume of a sphere and the area under a parabola 1 . Though Archimedes was most well-known for his inventions, using his knowledge on Physics, astronomy, mathematics, engineering and his intellect, he created three of the most incredible weapons of war: The Archimedes Screw, The Claw of Archimedes and The Heat Ray. The Archimedes Screw:
The Archimedes Screw was an invention that allowed man to move water up. Archimedes invented the ‘Archimedes Screw’ when King Hiero the second commissioned Archimedes to build a huge ship, the Syracusia. It was said that the Syracusia was capable of carrying 600 people, it also has a gym, garden decorations and a temple dedicated to the goddess Aphrodite. For a ship this big the hull would leak a considerable amount of water, to solve this problem Archimedes created the ‘Archimedes Screw’ to move water out of the hull 2.

Due to the claws ability to lift boats it became known as ‘The Ship Shaker’. The consisted of a long crane-like arm from which a large metal grappling hook was suspended. When the claw is dropped on an enemy ship, the arm would swing upwards lifting the ship up and thus possibly sinking
In the American Revolutionary War, a manned underwater craft named the American Turtle (or the "water-machine") was used against the British Navy. David Brushnell designed this ingenious machine in 1771. The submarine was a one manned, egg-shaped vessel which was propelled by hand-operated screw-like devices. It was bottom-heavy in order for it to remain upright. The operator would plant a submersible mine that could be triggered by a simple clockwork mechanism. He could paddle away after he attached the magazine of gunpowder onto the enemy ship. The operator could stay under for about thirty minutes
cannons on one side of the ship to free them from the mud holding the ship.
Geometry, a cornerstone in modern civilization, also had its beginnings in Ancient Greece. Euclid, a mathematician, formed many geometric proofs and theories [Document 5]. He also came to one of the most significant discoveries of math, Pi. This number showed the ratio between the diameter and circumference of a circle.
...to the Second Punic War with the defense of Syracuse. He even made amazing engineering tools and machines that benefitted the community, like the Archimedes screw, which helped irrigation among other things. The Archimedes’ principle, which is said to of helped King Hiero ll, showed the different densities between objects using the buoyancy of the water. The findings in mathematics from Archimedes like The Quadrature of the Parabola and the Measurement of a Circle have greatly benefitted mathematics and are still helping now. Archimedes wrote a lot of different works, including his most famous Archimedes Palimpsest, which contained many more important writing like On Floating Bodies. With his amazing inventions, intricate ideas on science, intelligent theorems and principles in mathematics, and his life in general, Archimedes has greatly affected society in many ways
Archimedes. The first one is the Archimedean screw which supposedly could serve as a water pump. The second invention was the compound pulley. The third invention
He invented swim fins to increase his speed in the water. He invented these when he was only eleven! He made his fins about eleven inches tall and six inches wide. He put a hole for his thumb on the board too. “When I was a boy, I made two oval [palettes] each about 10 inches long and six broad, with a hole for the thumb in order to retain it fast in the palm of my hand. They much resembled a painter’s [palettes]. In swimming, I pushed the edges of these forward and I struck the water with their flat surfaces as I drew them back. I remember I swam faster by means of these [palettes], but they fatigued my wrists.”
Rime of the Ancient Mariner: Wrong Actions The idea of people making wrong actions and having to pay for them afterwards is not new. The Christian religion centers itself around the confession of sins done by men or women. Luckily, they have the power to repent and do penance to receive God’s forgiveness. God sends people this power and people around the world mimic this cycle of crime, punishment, repentance, and reconciliation in court systems and other penal codes.
Euthyphro by Plato, challenges the core ethics of belief and fact. Socrates the main character of this story is being tried by Meletus for inventing new Gods, rejecting the old ones, and corrupting the youth of Athens with his beliefs. Euthyphro the other main character who is a priest, is astonished a man such as Socrates would be tried for such a crime. For Euthyphro also often doubted for his unique beliefs of divine matters and his predictions of the future. The main point of the story however, is Socrates questioning of Euthyphro’s reasoning and claims for prosecuting his father; even though his crime was murder of a murderer. This short essay will highlight and analyze the main faults Socrates sees within Euthyphro’s reasoning for prosecuting
As it filled with water, the bow submerged, raising the stern out of water. When the stern reached an angle of about 45 degrees, the stresses in the ship's midsection (15 tons per square inch) caused the steel to fail and the bow to rip loose and sink [Gannon, 1995].
Furthermore, one of the best innovations, the Persian Empire invented was canal building. They built canals for various reasons: to have drinkable water, to water farms, and to dispose wastes. However, their greatest innovation came around in 525 BC. Now I ask you a question, where and when the Suez Canal was constructed? The Suez Canal lies between Middle East and Egypt and it was completed in 1869. But when European engineers were in the middle of constructing the canal they found a statue with some writing on it which said, “I, Darius the Great, King of Persia, King of Kings, King of the World, commanded my men to build a canal so that the East and West can easily trade with each other.” They constructed the canal around 525 BC but years later when the Persian Empire was gone, the climate changed therefore the canal was destroyed. This will always be remembered as the greatest innovation of Persian Empire.
Hipparchus of Nicaea (c. 190 – c. 120 B.C.) was a Greek astronomer, geographer, and mathematician of the Hellenistic period. Many credit him as the founder of trigonometry. Hipparchus was born in Nicaea, Bithynia (now Iznik, Turkey) and most likely died on the island of Rhodes. He flourished during 162 to 127 B.C. as a working astronomer and is considered by many to be the greatest ancient astronomical observer and, by some, the greatest overall astronomer of antiquity. Utilizing the observations and mathematical techniques accumulated over the centuries by the Babylonians and other Mesopotamians, he was the first person whose quantitative and accurate models for the motion of the Sun and Moon still survive to this day. He developed trigonometry, constructed trigonometric tables, and solved several problems of spherical trigonometry. He may have been the first to develop a reliable method to predict solar eclipses, compiled the first comprehensive star catalog of the western world, and possibly invented the astrolabe and armillary sphere. He is most famous for his incidental discovery and measurement of Earth’s procession (Wikipedia). It is also believed that Hipparchus introduced Greece to the concept of the division of a circle into 360 degrees and Theon of Alexandria credits Hipparchus with a twelve-book treatise on chords. However, this work has been lost to history. It is believed Ptolemy’s famous table of chords was based on a Hipparchus’ treatise (History of Mathematics 175-177).
Euclid and Archimedes are two of the most important scientists and mathematicians of all time. Their achievements and discoveries play a pivotal role in today’s mathematics and sciences. A lot of the very basic principles and core subjects of mathematics, physics, engineering, inventing, and astronomy came from the innovations, inventions, and discoveries that were made by both Euclid and Archimedes.
Carl Friedrich Gauss is revered as a very important man in the world of mathematicians. The discoveries he completed while he was alive contributed to many areas of mathematics like geometry, statistics, number theory, statistics, and more. Gauss was an extremely brilliant mathematician and that is precisely why he is remembered all through today. Although Gauss left many contributions in each of the aforementioned fields, two of his discoveries in the fields of mathematics and astronomy seem to have had the most tremendous effect on modern day mathematics.
Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist, and the first Greek philosopher. He was an astronomer, merchant and mathematician, and after visiting Egypt he is said to have originated the science of deductive geometry. He also discovered theorems of elementary geometry and is said to have correctly predicted an eclipse of the sun. Many of his studies were in astronomy but he also observed static electricity. Phythogoras was a Greek philosopher. He discovered simple numerical ratios relating the musical tones of major consonances, to the length of the strings used in sounding them. The Pythagorean theorem was named after him, although this fundamental statements of deductive geometry was most likely first an idea from Egyptian methods of measurements. With the help of his followers he discovered that the earth was a sphere, but he did not believe it revolved around the sun.
The history of warships goes back in history to the ancient Greeks and Romans. Their ships were called galleys. The galleys were powered by oarsmen. The galley had a sharp point in the front for ramming other ships. In the A. D. 700's, the Vikings invented the long ship. It weighed less than the galley and was stronger and more seaworthy. The Viking's controlled the seas until the 1000's. By the 1500's most warships carried guns, and later became heavily armed ships.
