![]() ![]() By 1967, with the help of the computer age, the value of π was determined to have 500,000 decimal places. Then over the course of 200 years, the digits grew extensively. In 1797, Carl Friedrich Gauss determined π to 205 decimal places. In 1717, French mathematician De Lagny determined that π had 127 decimal places. In 1706, John Machin found π to one hundred decimal places. In the late sixteen hundreds, astronomer Abraham Sharp found π to seventy-two decimal digits. Using a polygon with this many sides, van Ceulen determined a value of π to twenty decimal places.Īnd so, the digits of π grew. Three years later, another Dutchman, Ludolph van Ceulen, also employed Archimedes’s methods and used a polygon with 6 x 2 29 sides. His calculation of π consisted of fifteen decimal places. However, Dutch mathematician Adrian Van Rooman outdid Viete by employing Archimedes’s methods by circumscribing and inscribing a circle with a polygon of 2 30 sides. In 1593, Francois Viete estimated π to an accuracy of nine decimal places. The accuracy of π and the number of digits slowly grew over the years. Then, 400 years later, around 150 CE, the astronomer Ptolemy used π to five digits, which was 3.1416. The Ostomachion is a puzzle that utilizes combinatorics to explain how many ways we can assemble fourteen different shaped pieces to form a square.Īrchimedes’s method of approximation of π with inscribed and circumscribed polygons – graphic by Gabrielle Birchak His work, The Ostomachion, is a dissection puzzle, which was part of the larger treatise called Archimedes Palimpsest. His process utilized values in base 100,000,000. As a result, he stated that we could define the amount of sand in our universe in vast numbers expressed in exponential form. He authored the book The Sand Reckoner to prove that the amount of sand in the universe is not infinite. However, Archimedes’s most significant contribution to science included his groundbreaking mathematics, a subject to which he devoted his life. He also designed his parabolic reflector, which the Sicilian military used to reflect the Sun and burn approaching enemy ships. ![]() One such tool included the claw of Archimedes, which was a giant iron claw attached to a pulley and lever that attempted to capsize approaching boats. The efficacious Archimedes screw, still used today, helps to pump rainstorm runoff and propel dry, bulk materials.ĭuring the siege of Syracuse, he designed military hardware.
