What was Archimedes's invention?
Archimedes was born in Syracuse, which was very prone to attack from the Romans. He tried to invent some instruments based on mathematical principles that would help people of Syracuse fight against the Romans. One of them was the Death Ray, which was made up of a number of parabolic mirrors. These mirrors were made up of highly polished bronze and copper metals. They are placed in such a way that the sun rays falling on the mirror converge to a particular point. Any enemy ship arriving at that point will get burn by the strong sun rays reflected by the mirror, and the ship will eventually sink into the sea.
What did Archimedes do?
Not only Mathematics, he made many valuable inventions in the field of Physics as well. Apart from being a mathematician, he was also an astronomer and made many significant contributions in the field of astronomy. In the life span of 75 years, he introduced various laws and theories related to mathematics. Today, we all are able to measure area and volume of different shapes with the help of relevant laws, theorems, and formulae, but we don’t know from where all these laws and formulae came. Area and volume of different 3D and 2D shapes were given by Archimedes. We can not think of mathematics without him and his inventions. Many more inventions made by him are there that we still have to acknowledge. Let us briefly discuss his inventions one by one.
What is Archimedes best known for?
Archimedes is best known for his ‘EUREKA’ moment when he came up with the concept of ‘buoyancy’ which is considered one of the most valuable findings in the field of physics. With the help of buoyancy, he was able to calculate the volume of irregular objects. One day, he stepped into a bathtub full of water up to the edge. He noticed that as he stepped inside, some water was displaced from the bathtub. It was then that he realized that the volume of the body inside the water is equal to the volume of water displaced by it, which can be easily calculated.
Who invented integral calculus?
Archimedes was the first who invent integral calculus, i.e., around 2000 years before Newton and Leibniz. Infinitesimal is that quantity that tends to infinity, means it tends to something that does not usually exist or is unreal.

Who came up with the ratio of volume and surface area of a sphere and a cylinder?
Archimedes was the first who came up with the ratio of volume and surface area of sphere and cylinder. This is considered one of the most significant contributions of Archimedes to mathematics, and even Archimedes himself considered it to be his most valuable contribution to this field as he established a relationship between a cylinder and a sphere (enclosed in cylinder) having same height and diameter. He proved that volume and surface area of a sphere is 2/3rd of that of a cylinder. He was so influenced by this discovery that he requested to built his tomb in the shape of a cylinder having a sphere circumscribed in it .

How many works of Archimedes are there?
There are nine extant treatises by Archimedes in Greek. The principal results in On the Sphere and Cylinder (in two books) are that the surface area of any sphere of radius r is four times that of its greatest circle (in modern notation, S = 4π r2) and that the volume of a sphere is two-thirds that of the cylinder in which it is inscribed (leading immediately to the formula for the volume, V = 4/3 π r3 ). Archimedes was proud enough of the latter discovery to leave instructions for his tomb to be marked 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.

According to Vitruvius, a votive crown for a temple had been made for King Hiero II of Syracuse, who had supplied the pure gold to be used; Archimedes was asked to determine whether some silver had been substituted by the dishonest goldsmith. Archimedes had to solve the problem without damaging the crown, so he could not melt it down into a regularly shaped body in order to calculate its density .

What is the claw of Archimedes?
The Claw of Archimedes is a weapon that he is said to have designed in order to defend the city of Syracuse. Also known as "the ship shaker", the claw consisted of a crane-like arm from which a large metal grappling hook was suspended. When the claw was dropped onto an attacking ship the arm would swing upwards, lifting the ship out of the water and possibly sinking it. There have been modern experiments to test the feasibility of the claw, and in 2005 a television documentary entitled Superweapons of the Ancient World built a version of the claw and concluded that it was a workable device.
