Many high school mathematics students unrealistically believe that if they can just finish one more general mathematics course, they will never again have to face mathematics. They realize that they must know how to write checks and are quite eager to learn about managing a checking account. Other than this banking activity, they are quite sure that only engineers and mathematics teachers use mathematics on a daily basis. When asked about such items as taxes and insurance, the stock answer is, “Oh, I'll just let my accountant take care of things like that!”

Now… John Snyder has always loved maps, beginning with his elementary school days in Indianapolis. Everyone who knew John identified him with the maps he loved. Oftentimes the greeting cards he received carried a map motif. When John reached high school, his interest in maps was further developed as he studied trigonometry, calculus, and algebra and could apply the concepts developed in those courses to map projection, the science of transforming the earth's spherical surface to a flat, two-dimensional piece of paper. After high school, John's avid interest in chemistry, coupled with World War II's push for more scientists and engineers, helped him choose a career path as a chemical engineer.

Now… Shreveport is a large town in Northwest Louisiana. A state that is classified as a severe-weather area. Northern Louisiana is often hit by thunderstorms and tornadoes. Southern Louisiana, on the Gulf of Mexico, is susceptible to hurricanes during late summer. When the manager of television station KSLA in Shreveport began looking for a person to fill the weather-news slot a few years ago, he did not want someone who could just point to a weather map. He wanted a good meteorologist. In regions that have invariant weather, those people who give the weather are usually actors or actresses who read the predictions prepared by someone else. The study of weather, however, is called meteorology, and a professional meteorologist is someone who has a degree in weather study. Even in area with severeweather conditions, some television stations do not hire a professional meteorologist but hire a broadcast meteorologist instead. A broadcast meteorologist is a journalist who has taken general courses in meteorology while studying for a communications or journalism degree.
