Adventure Games, Permutations and Spreadsheets  Puzzles have long been a source of motivation for the exploration of mathematical concepts, theory, and computation. Multimedia adventure games with creative storylines, movies, sophisticated graphics, and sound, are the modern context for both new and classic puzzles. We will show how some of these puzzles can be modeled with directed graphs and the resulting mathematical work can be carried out with nothing more than a computer spreadsheet.

The Diet Problem  The goal of the diet problem is to find the cheapest combination of foods that will satisfy all the daily nutritional requirements of a person. The problem is formulated as a linear program where the objective is to minimize cost and meet constraints which require that nutritional needs be satisfied. We include constraints that regulate the number of calories and amounts of vitamins, minerals, fats, sodium and cholesterol in the diet. The diet problem case study is part of the NEOS Guide, an online book about optimization. The Optimization Technology Center (Argonne National Lab and Northwestern University) seeks to make optimization information available through the NEOS Guide and the NEOS Server.

Famous Nonmathematicians  We often tell our students that there are many things besides teaching and actuarial work that they can do with a degree in mathematics, but I don't think they believe us. Over the years, I've put together a list of wellknown people who were math majors (or some equivalent in other countries and times), although not all of them completed their degrees.

Fields Prizes  At the 1924 International Congress of Mathematicians in Toronto, a resolution was adopted that at each ICM, two gold medals should be awarded to recognize outstanding mathematical achievement. Professor J. D. Fields, a Canadian mathematician who was secretary of the 1924 Congress, later donated funds establishing the medals which were named in his honor. The Fields prizes can be considered as the Nobel Prizes in Mathematics.
