In this intriguing business novel, which illustrates state-of-the-art economic theory, Alex Rogo is a UniCo plant manager whose factory and marriage are failing. To revitalize the plant, he follows piecemeal advice from an elusive former college professor who teaches, for example, that reduction in the efficiency of some plant operations may make the entire operation more productive. Alex's attempts to find the path to profitability and to engage his employees in the struggle involve the listener; and thankfully the authors' economic models.

Using the unique business-novel format, It's Not Luck continues the story of The Goal protagonist Alex Rogo as he navigates a new set of challenges facing the now over-diversified and under-profitable UniCo, where he has risen to the rank of division manager.

Since it was first introduced in the multi-million-copy best seller The Goal, Dr. Eliyahu Goldratt's Theory of Constraints (TOC) has emerged as one of the most flexible and effective approaches to management and problem solving in the corporate world.

Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves. Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes "backwards" sometimes; how to turn the tide in the fight against AIDS.
