What We Are Reading Today: Trigonometric delights by Eli Maor

Trigonometry has a reputation as a dry, difficult branch of mathematics, a glorified form of geometry complicated by tedious computation. 

In Trigonometric Delights, Eli Maor dispels this view. Rejecting the usual descriptions of sine, cosine, and their trigonometric relatives, he brings the subject to life in a compelling blend of history, biography, and mathematics. 

From the proto-trigonometry of the Egyptian pyramid builders and the first true trigonometry developed by Greek astronomers, to the epicycles and hypocycles of the toy Spirograph, Maor presents 

both a survey of the main elements of trigonometry and a unique account of its vital contribution to science and social growth. 

A tapestry of stories, curiosities, insights, and illustrations, Trigonometric Delights irrevocably changes how we see this essential mathematical discipline.

What We Are Reading Today: Playbooks and Checkbooks by Stefan Szymanski

What economic rules govern sports? How does the sports business differ from other businesses? Playbooks and Checkbooks takes a fascinating step-by-step look at the fundamental economic relationships shaping modern sports. 

Focusing on the ways that the sports business does and does not overlap with economics, the book uncovers the core paradox at the heart of the sports industry. Unlike other businesses, the sports industry would not survive if competitors obliterated each other to extinction, financially or otherwise — without rivals there is nothing to sell. Playbooks and Checkbooks examines how this unique economic truth plays out in the sports world, both on and off the field.

Noted economist Stefan Szymanski explains how modern sporting contests have evolved; how sports competitions are organized; and how economics has guided antitrust, monopoly, and cartel issues in the sporting world. Szymanski considers the motivation provided by prize money, uncovers discrepancies in players’ salaries.
