The book has three sections: The first deals with euclidean geometry and geometric constructions; the second covers noneuclidean geometry, including hyperbolic, elliptic, taxicab, and finite geometries; and the final section covers symmetry.
He then moves to applications in Fourier series, including strings and springs, and devotes the rest of the text to the calculus of variations, including Euler's Equation, harmonic functions, Hamilton's Action and Lagranges' Equation, finishing with nonEuclidean geometry and some fun with relativity.
