The four-color theorem, “states that any map in a plane can be colored using four-colors in such a way that regions sharing a common boundary (other than a single point) do not share the same color” (Weisstein, n.d.) . The objective of The Four Color Theorem is to use fewer colors without making the same colors attach. “The Four Color Theorem is important to the mathematical field considering it was first stated in 1852, but was not proved until 1976. For over one hundred and twenty years some of the best mathematical brains in the world were unsuccessful in proving one of the simplest theorems in mathematics” (Pierce 2011). The four color theorem was not proved until Appel and Haken used a computer to prove the theorem and many mathematicians believed it was cheating to let the computer do all the work and not by hand. The major parts of the four color theorem can be broken down into three parts that help us learn about its background, the use of four color theorem, and the benefits we use in today’s world.
The four color theorem came into play, when mathematicians searched for ways to see the boundaries between each region or area. Author of the four color theorem, Francis Guthrie was a student at University College London where he tried to find ways to use only four colors to color the map of counties in England without making the same color attach. Guthrie was a student of Professor Augustus De Morgan when he needed to know if the theorem can be proven, but after he graduated he studied law until his brother became a student under Professor De Morgan. Later on, “He asked his brother Frederick if it was true that any map can be colored using four colors in such a way that adjacent regions (i.e. those sharing a common boundary segment, not just a point) receive different colors. Frederick Guthrie then communicated the conjecture to DeMorgan” (Robertson et al.

331 Words | 2 PagesOnly certain type of numbers showed the error, while most users would never encounter the flaw. On June 13, 1994, Dr. Thomas Nicely discovered that some of his calculations done on a computer with the new Pentium chip came back incorrect. He only discovered this because of earlier calculations done on other computers resulted in different amounts. He was only able to deduce that it was something wrong with the new Pentium chip by eliminating all other factors, such as the motherboard chipset or programming errors. On October 24,1994, Dr. Nicely notified Intel about his findings.

Flaws are not uncommon in complicated integrated circuits, and most of them go unnoticed by the user, however, the Pentium flaw was very different. The nature of the flaw was in the floating point math subsection of the Pentium microprocessor, it caused incorrect answers when preforming double-precision arithmetic. In October of 1994 a man named Thomas Nicely, a mathematics professor at Lynchburg collage in Virginia was the first to notice this flaw. He found that the results of some of his calculations were incorrect.

There is little doubt that the biblical calculations came from crude measurements but there is strong support that the Babylonians and Egyptians found π by using mathematical equations. The Greeks first focus on π was around 434 BC when mathematician Anaxagor made an unsuccessful attempt at finding π which he called squaring the circle. It took the Greeks over 100 years of study to find a value for π. In 240 BC, Archimedes of Syracuse concluded his study of π with 223/71<π<22/7.
