by Professor John Frohliger, St. Norbert College

"The Golden Ratio"

Past Lectures: "Finding the Odd Weight", "Worms, Blocks, and Harmony", "Honey, Where Shall We Sit?" and "One Potato, Two Potato, ..."

Abstract: Originally the Golden Ratio was used to describe a relationship between the sides of a particular type of rectangle. Like many concepts, however, the ratio may have started in one corner of mathematics but it branched out to others. We will look at the ratio in its original definition and discover how it can be found in other areas of math including, not only geometry, but sequences and even peg-jumping puzzles.
