Airlines and Linear Programming 

Airlines use linear programming to maximize profits on ticket sales, organize pilot schedules, and to make money! 

Cooking  Weights and Proportions 

Using proportions, weight, and time while cooking a turkey. 

Creative Cooking 

Learning how to manipulate recipes using math. 

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. 

Gambling and the Odds 

Mathematics explains why casinos and lotteries make money. Math also enables players to make bets based on probability and numbers. 

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. 

Leonardo DaVinci and the Golden Section 

Leonardo DaVinci created many masterpieces that depicted the golden ratio and other elements of mathematics. 

Linear Programming 

Linear Programming is using linear equations and inequations to maximize profits and minimize costs. Linear Programming is an important part of operations research. 

Making Enough: Working with Recipes 

Working with recipes and fractions to produce just the right amount of food. 

The Manufacturing Industry 

The manufacturing industry relies heavily on advanced mathematics and linear programming. This is a small listing of the many industries that use linear programming in their operations research. 

The Mathematics of Art 

The link between mathematics and art can be realized by considering artists like Leonardo DaVinci and M. C. Escher, as well as through the golden ratio and the Fibonacci sequence. 

Math in the Kitchen 

The mathematics involved in cooking is very broad and includes making conversions, working with numbers in recipes, operations with fractions, and estimating time and cost, among other things. 

Math in the Squad Car 

While on patrol, police officers need to apply their math skills for a variety of tasks. 

Medicine and Math 

Doctors and nurses use math every day, doing routine tasks such as writing prescriptions or administering medication to patients. Math can also be seen in more advanced medical procedures such as CAT scans and the treatment of kidney stones. 

Moored Ships 

Mooring large ships both in open water and at port is an issue of safety. The problem finds how to safely constrain a ship at dock, minimizing it’s movement to ensure that it can safely be loaded and unloaded. 

Music, Math, and Patterns 

We use math to read music, to describe and define music, and to create beauty witin music. Math and music relate through patterns. 

Navigation 

Two successful navigation systems known as Loran (Long Range Navigation) and GPS (Global Positioning System) are based on the principles of the hyperbola and the circle, as well as the idea of trilateration. 

Piped Water Cooling of a Concrete Slab 

Concrete is the most widely used building material in the world. Through a process called mineral hydration, the cement bonds the other components together and forms a rock like structure known as concrete. The reaction between cement and water is highly exothermic so if the hydration process occurs too quickly the concrete will not form strong bonds. It is desirable to slow down the reaction by cooling so the structure of the concrete will not be compromised. 

The Police 

Officers in the Royal Canadian Mounted Police (RCMP) use a variety of math concepts everyday in their line of work. They use math while on patrol and more specifically in accident reconstruction and crime scene investigation. 

Ratios and Proportions Used in Medicine 

Nurses particularly use proportions on a regular basis when following doctor's orders.
