How do pyramid scams work? Are reality television shows fair?
Why are sports so uncompetitive? Who really broke the bank in 2009?
Our world has become more complicated, and the notion of growth at any cost has led to constant economic uncertainty, a permanently stressed-out workforce, and everyday stories of government and corporate abuse. Author John K. White argues that a better knowledge of basic systems is needed to understand the world we live in, from pyramid scams to government bailouts, from sports leagues to stock markets, from the everyday to the seemingly complex.

The Mathematics of Change: A New World Model
What do Aesop's fable about a race between a tortoise and a hare, the Dow Jones industrial average, and a Formula 1 car have in common? They all deal with change—in the distance run by two animals in a storybook race, in a stock market index (a measure of the performance of a widely held group of stocks1), and in the speed of a car. Fortunately, to analyze the data in all three cases, the mathematics is the same.
3.1. The Measure and the Change in the Measure
Perhaps the most fabled race in all folklore is that of the tortoise and the hare. Aesop gives little information about the race, but ...
