 Accident Reconstruction Specialist use complex formulas and advanced mathematics to find out the series of events leading up to, during, and after a traffic accident. Their opinions and findings are used as influential evidence in court. Applications of Integers Integers are everywhere. Negative integers, which may be less obviously seen, can be found on thermometers, in hockey, when measuring altitude, and in banks. Carbon 14 Dating Carbon 14 Dating is an example of how specialists use exponential decay to find dates of death for various organic organisms. CAT Scans CAT scans use tomography, which is the detailed imaging of sections, to find a more in depth, three-dimensional view of an internal organ, most commonly the brain. The Challenger Rocket The devastating explosion of the Challenger rocket in 1986 led to an important investigation to understand the cause of the failure. Probability aids in explaining the malfunction of the shuttle. Chess The game of chess has many mathematical applications, other than the obvious concepts of problem solving and logic. Construction and Design Architects, engineers, design professionals, and everyday people use math in construction and design. Math can be seen in architecture and design through symmetry, frieze patterns, bridges, and construction problems that are encountered by people everyday. Cooking Conversions When working with recipes, it is important to understand how to convert temperatures and imperial/metric units. Cooking - Weights and Proportions Using proportions, weight, and time while cooking a turkey. Creative Cooking Learning how to manipulate recipes using math. Epicenter of an Earthquake The epicenter of an earthquake is located by using circle geometry and special devices called seismometers. Expected Value of an Outcome Expected value is an estimate of how much a player can expect to win or lose when placing the same bet over and over again. Exponential Decay Exponential Decay describes a rapid decrease. Exponential decay can be seen in a variety of places, including radiocarbon dating and the decay of dangerous chemicals. Gambling and the Odds Mathematics explains why casinos and lotteries make money. Math also enables players to make bets based on probability and numbers. Games of Strategy The strategy behind particular games, such as chess, sudoku, or mancala, can be mathematically analyzed as Combinatorial Game Theory. The Global Positioning System and Circles The Global Positioning System is based on common mathematical equations of distance and speed. Trilateration enables GPS receivers to find the latitude, longitude, and altitude of a receiver, anywhere on the earth. Knowledgeable Gambling: Independent vs Dependent Events Math allows players to make knowledgeable bets when playing games of dependent events, such as Poker or Blackjack. Independent events remind gamblers that there is no guarantee of winning. Leonardo DaVinci and the Golden Section Leonardo DaVinci created many masterpieces that depicted the golden ratio and other elements of mathematics. Long Range Navigation System Three stations, located along the coast, use hyperbolics branches to locate ships at sea. This system is known as Long Range Navigation (Loran).
