Archimedes is known as one of the three greatest mathematicians of all time, along with Newton and Gauss. He was known by many as "the wise one." Others referred to him as "the master." However, he was most well known as "the great geometer."

Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.

he discovery of which Archimedes claimed to be most proud was that of the relationship between a sphere and a circumscribing cylinder of the same height and diameter. He calculated the volume of a sphere as ⁴⁄₃πr ³, and that of a cylinder of the same height and diameter as 2πr ³. The surface area was 4πr ² for the sphere, and 6πr ² for the cylinder (including its two bases). Therefore, it turns out that the sphere has a volume equal to two-thirds that of the cylinder, and a surface area also equal to two-thirds that of the cylinder. Archimedes was so pleased with this result that a sculpted sphere and cylinder were supposed to have been placed on his tomb of at his request.

Archimedes’ most sophisticated use of the method of exhaustion, which remained unsurpassed until the development of integral calculus in the 17th Century, was his proof - known as the Quadrature of the Parabola - that the area of a parabolic segment is ⁴⁄₃that of a certain inscribed triangle. He dissected the area of a parabolic segment (the region enclosed by a parabola and a line) into infinitely many triangles whose areas form a geometric progression. He then computed the sum of the resulting geometric series, and proved that this is the area of the parabolic segment.

Archimedes produced formulas to calculate the areas of regular shapes, using a revolutionary method of capturing new shapes by using shapes he already understood. For example, to estimate the area of a circle, he constructed a larger polygon outside the circle and a smaller one inside it. He first enclosed the circle in a triangle, then in a square, pentagon, hexagon, etc, etc, each time approximating the area of the circle more closely. By this so-called “method of exhaustion” (or simply “Archimedes’ Method”), he effectively homed in on a value for one of the most important numbers in all of mathematics, π. His estimate was between 3¹⁄₇ (approximately 3.1429) and 3¹⁰⁄₇₁ (approximately 3.1408), which compares well with its actual value of approximately 3.1416.

Archimedes found a way to measure volume of irregular objects. This was important in the calculation of their density. The story goes that Archimedes was asked by the ruler of Greece to see if his new crown was properly made. The king wanted to see if the crown that was made for him was all gold or had been mixed with other worthless materials. He found the volume of the crown and discovered that it's density was not what it should have been. He made his discovery in the bathtub, realizing he displace his volume in water. He ran along the streets of Greece naked yelling "Eurika", or "I found it!". It turns out that the goldsmith who made the crown lied to the king, and the king had him beheaded.
