: Proves that a straightedge alone is sufficient for these constructions, provided a single circle is already present on the plane.

: The book’s technical highlight is Carl Friedrich Gauss’s algebraic proof for constructing a regular 17-sided polygon using only a straightedge and compass—a feat that eluded mathematicians for two millennia.

The text extends beyond classical geometry to modern "recreational" mathematics that has evolved into rigorous fields: : Proves that a straightedge alone is sufficient

serves as a bridge between high-school level mathematics and the profound, often counterintuitive results that typically remain hidden within advanced textbooks. Written by Mordechai (Moti) Ben-Ari, a professor emeritus at the Weizmann Institute of Science, the book champions the idea that mathematics is not just a collection of rules, but a source of aesthetic delight and intellectual intrigue.

: Ben-Ari covers the Five-Color and Six-Color theorems, as well as Ramsey Theory, which investigates how large a system must be to guarantee a certain level of order. Accessibility and Pedagogy (PDF) Mathematical Surprises - ResearchGate
