Projects! This book culminates with a chapter containing fifteen projects of varying difficulty. Each project has a guided portion and an unguided portion. The titles in the table of contents indicate what each project is about. We encourage you to discuss these projects with your friends at your next party. We would. In the spotlight Hilbert’s Seventh Problem we learn about Hilbert’s speech to the International Congress of Mathematicians in Paris in 1900. We learn how one of these famous problems is connected to the question of when a transcendental number to a transcendental power can possibly be algebraic—a question discussed in one of the projects.
