Archimedes’ ScrewĪrchimedes’ screw was more of a pump than a screw. A warship could easily be overturned by the claw as Archimedes had taken into account the buoyancy of the water. This was known as the Claw of Archimedes or “the iron hand.”Īrchimedes was an architect as well as a scientist, and the Claw of Archimedes was also a magnificent piece of architecture which allowed the people of Syracuse to defend themselves against Roman invasion by sea. To protect the city from enemies, Archimedes designed a hook that could latch on to an enemy ship and sink it. The Claw of ArchimedesĪrchimedes was from the coastal city of Syracuse in present-day Italy, then a Greek territory. Pi can also be used to calculate the area of a sphere as well as of a hemisphere. Various applications of Pi have been seen in mathematics, such as working out the area of a circle. Archimedes also circumscribed various shapes in the circle. Pi the ratio of the circumference of a circle to the diameter. Pi’s numerical value is approximately 3.14 which is calculated by dividing 22 by 7. Pi is a Greek symbol which is used in various formulae, and Archimedes was able to derive the value of Pi using his exceptional intellect.
Evaluation of Pi (π)Īrchimedes used the Hellenistic method of mathematics. The highest number ever counted is 8*1063, as demonstrated in Archimedes’ Sand Reckoner, where he estimated that it would take 8 *1063 grains of sand to cover the universe. Archimedes established a new theory in mathematics which could count numbers to an infinite value. Until that time, the Greeks had represented the number system using various symbols.

The Sand Reckoner is a work by Archimedes in which he attempts to count the number of grains of sand it would take to cover the universe.įirst, Archimedes had to work out how to count a number with a large base, leading him to take a major step in the field of mathematics. Imagine counting grains of sand! This is what Archimedes set out to do. The lactometer (an instrument used to measure the purity of milk) is also based on the above principle. This law has been instrumental in understanding maritime principles used by ships and submarines, all of which are designed using the buoyancy principle. The weight of the displaced liquid tells us if the object will float or sink. Archimedes’ principle also helps us to understand why something floats or sinks by showing that the amount of liquid displaced is the measure of the sinking or rising capability of the object. A variety of forces act on a body in any liquid. When a solid body falls into a liquid, it displaces the same amount of liquid as the volume of the body immersed in it. Archimedes principle is quite a challenging concept for many of us to grasp, but it basically concerns the theory of buoyancy.
