Phi, Pi, e, and i - Spectrum David Perkins

Certain constants occupy precise balancing points in the cosmos of number, like habitable planets sprinkled throughout our galaxy at just the right distances from their suns. This book introduces and connects four of these constants (phi, pi, e and i). The authors discuss their properties, as a group, at a level appropriate for an audience armed only with the tools of elementary calculus.
