Archimedes was born c. 287 BC in the seaport city of Syracuse, Sicily, at that time a self-governing colony in Magna Graecia.The date of birth is based on a statement by the Byzantine Greek historian John Tzetzes that Archimedes lived for 75 years before his death in 212 BC. In the Sand-Reckoner, Archimedes gives his father's name as Phidias, an astronomer about whom …
Not only was that his role in history, but that was how he saw himself: like virtually all great thinkers of the Greek and Roman worlds, he viewed the role of the practical scientist as on a level with that of the artisan—and since most artisans were slaves, he considered applied science as something infinitely less noble than pure science. This is of course an irony, given his great …
In it Archimedes determines the different positions of stability that a right paraboloid of revolution assumes when floating in a fluid of greater specific gravity, according to geometric and hydrostatic variations. Archimedes is known, from references of later authors, to have written a number of other works that have not survived.
His method is called the method of exhaustion, developed rigorously about a century earlier by one of Archimedes’ heroes, Eudoxus of Cnidus. Archimedes imagined a circle, and in his mind drew an equilateral triangle inside it, with each point of the triangle touching the circle.
In the 3rd Century BC, Archimedes: invented the sciences of mechanics and hydrostatics. discovered the laws of levers and pulleys, which allow us to move heavy objects using small forces. invented one of the most fundamental concepts of physics – the center of gravity.
The story goes that Archimedes stepped into the bath and caused it to overflow. This made him think. The water that had splashed out of the tub when he stepped in was equal to the volume taken up by his body. It was this discovery that provided Archimedes with the solution to King Hiero's gold crown problem.
The Archimedes screw was soon also used to transport water from low-lying areas up to irrigation ditches. The design is so effective that it is still being used today. For instance, it is used to lift wastewater in water treatment plants and even to lift water in some amusement park rides.Jul 11, 2019
Archimedes is especially important for his discovery of the relation between the surface and volume of a sphere and its circumscribing cylinder. He is known for his formulation of a hydrostatic principle (known as Archimedes' principle) and a device for raising water, still used, known as the Archimedes screw.
Archimedes was the greatest mathematician of his age. His contributions in geometry revolutionised the subject and his methods anticipated the integral calculus. He was a practical man who invented a wide variety of machines including pulleys and the Archimidean screw pumping device.
That Archimedes discovered his principle when he saw the water in his bathtub rise as he got in and that he rushed out naked shouting “Eureka!” (“I have found it!”) is believed to be a later embellishment to the story. Learn more about the life of Archimedes.
An Archimedes' screw is a simple machine (a type of pump) which lifts water up when it is turned. It has been used since ancient times. It is used mainly for lifting water from a lower to higher level, such as rivers or lakes, to irrigate fields, and also for draining water out of mines.
The Archimedes screw is a machine that carries water upward from one level to another. It is believed to have been invented more than 2,000 years ago by the ancient Greek mathematician Archimedes. The device is still used today.

Again, Archimedes perfected the existing technology, creating the first fully realized block-and-tackle system using compound pulleys and cranes. This he demonstrated, according to one story, by moving a fully loaded ship single-handedly while remaining seated some distance away.
Despite these novel inventions, Archimedes devised defensive devices to counter the Roman efforts including a huge crane operated hook – the Claw of Archimedes – that was used to lift the enemy ships out of the sea before dropping them to their doom.

Archimedes’ legacy: inventions and discoveries. Look no further than Archimedes for the embodiment of a man ahead of his time. Even among his peers, who practiced philosophy, arts and established democracy more than two thousand years ago, Archimedes of Syracuse outshined them all. by Tibi Puiu. January 29, 2021.
Archimedes was so proud of this achievement that he left instructions for his tomb to be inscribed with “a sphere inscribed in a cylinder.”. Marcus Tullius Cicero (106–43 bce) found the tomb, overgrown with vegetation, a century and a half after Archimedes’ death.
Archimedes found a way to approximate it with a method called “squaring the circle”. He first created a square inscribed inside of the circle (inscribed means that it exactly fits inside, with its vertices just touching the edge of the circle). Since he knew the area of the square is (the product of two sides), it was clear that the area of the circle is bigger than the area of that inscribed square. He then fitted a polygon with six sides instead of four within the circle and computed its area; he gradually worked his way up with more complex polygons to get even closer to the circle’s true area.

Even amongst peers that practiced philosophy and the arts as well as established democracy, Archimedes of Syracuse outshined them all.A true polymath, Archimedes was active in the fields of astronomy, geometry, logic, physics, and mathematics, and was recognized as ...
It was, in effect, the first odometer,” according to Encyclopedia Britannia. This mechanism is said to have been invented by Archimedes during the First Punic War. It seems to have been used until the time of Emperor Commodus (192A.D.) and then was lost in Europe until the middle of the fifteenth century.
According to the Roman architect Vitruvius, the Syracusan king Hiero II commissioned a gold crown shaped like a laurel wreath to be placed in a temple. 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.
Archimedes' law of the lever. Equal weights at equal distances are in equilibrium, and equal weights at unequal distances are not in equilibrium but incline towards the weight which is at the greater distance. If, when weights at certain distances are in equilibrium, something is added to one of the weights, they are not in equilibrium ...
As a young man, Archimedes may have studied in Alexandria with the mathematicians who came after Euclid. It is very likely that there he became friends with Conon of Samos and Eratosthenes of Cyrene. Eratosthenes. Learn how Eratosthenes measured Earth’s size.

Archimedes wrote nine treatises that survive. In On the Sphere and Cylinder, he showed that the surface area of a sphere with radius r is 4π r 2 and that the volume of a sphere inscribed within a cylinder is two-thirds that of the cylinder. (Archimedes was so proud of the latter result that a diagram of it was engraved on his tomb.)
Almost nothing is known about Archimedes’ family other than that his father, Phidias, was an astronomer. The Greek historian Plutarch wrote that Archimedes was related to Heiron II, the king of Syracuse. As a young man, Archimedes may have studied in Alexandria with the mathematicians who came after Euclid.
One story told about Archimedes’ death is that he was killed by a Roman soldier after he refused to leave his mathematical work. However Archimedes died, the Roman general Marcus Claudius Marcellus regretted his death because Marcellus admired Archimedes for the many clever machines he had built to defend Syracuse.
On Spirals develops many properties of tangents to, and areas associated with, the spiral of Archimedes —i.e., the locus of a point moving with uniform speed along a straight line that itself is rotating with uniform speed about a fixed point.
Marcus Tullius Cicero (106–43 bce) found the tomb, overgrown with vegetation, a century and a half after Archimedes’ death. The volume of a sphere is 4π r3 /3, and the volume of the circumscribing cylinder is 2π r3. The surface area of a sphere is 4π r2, and the surface area of the circumscribing cylinder is 6π r2.

The mystery of Archimedes’ mathematics wasn’t solved until 1906, when Professor Johan Heiberg discovered a book in the city of Constantinople, Turkey. (The city is now, of course, called Istanbul.)
As a young man he spent time in the Egyptian city of Alexandria, where Alexander the Great’s successor, Ptolemy Lagides, had built the world’s greatest library. The Library of Alexandria, with its meeting rooms and lecture halls, had become the focal point for scholars in the ancient world.
We do not know what he really looked like. Archimedes was born in the Greek city-state of Syracuse on the island of Sicily in approximately 287 BC. His father, Phidias, was an astronomer.
His method is called the method of exhaustion, developed rigorously about a century earlier by one of Archimedes’ heroes, Eudoxus of Cnidus. Archimedes imagined a circle, and in his mind drew an equilateral triangle inside it, with each point of the triangle touching the circle.

It can be useful in measuring the volume of irregular objects, such as gold crowns, as well as explaining the behaviors of any object placed in any fluid.
One of his inventions was the Archimedes screw. This device uses a corkscrew with a hollow tube.
Many of his inventions, theories and concepts are still in use today. Perhaps his best-known achievement was his "Eureka" moment, when he discovered the principle of buoyancy.
Archimedes has gone down in history as the guy who ran naked through the streets of Syracuse shouting "Eureka!". — or "I have it!". in Greek. The story behind that event was that Archimedes was charged with proving that a new crown made for Hieron, the king of Syracuse, was not pure gold as the goldsmith had claimed.
These dips can then be used to derive the water volume that was displaced leading to the force used to keep the water-bugs afloat. The authors said there is a great deal of interest in understanding the physics behind the water-walking bugs in order to create biomimetic water-walking robots.
At that time, Syracuse was one of the most influential cities of the ancient world, according to Scientific American. Trading vessels from Egypt, Greece and Phoenicia filled the city-state's harbor. It was also a hub of commerce, art and science, according to the Archimedes Palimpsest. After studying geometry and astronomy in Alexandria, ...

Archimedes was one of the most prominent mathematicians of Ancient Greek. His inventions and theories have helped physicists, mathematicians, engineers and astronomers for more than two millennia.
1. Archimedes Theory. One of the greatest contributions of Archimedes was his theory that allows the measurement of the volume of an irregularly shaped object. This is today known as Archimedes’ Principle. If playback doesn't begin shortly, try restarting your device. An error occurred while retrieving sharing information.
Archimedes developed a process, which he called method of exhaustion , using which he could figure out the value of pi. Figuring out pi paved the way to measure the volume or area of circles, cones, pyramids, spheres or any shape and object that had irregular surfaces or curved lines.
His way of working with infinitesimal numbers was very similar to how calculus is done today. He had successfully figured out the square root of 3. Although he did not set the value at 1.7320508, he said that it would be between 1.7320261 and 1.7320512, which is extremely close.
If Syracuse or the king needed something, if the army needed help or if he had to defend his city , he would come up with unique solution. Such needs lead to the development of Archimedes’ screw, Archimedes’ claw and many other minor and major devices, as well as strategies, that were for the welfare of the city, the people and of course the king.
