"A captivating, pleasing, and instructive booklet …. The writing is outstandingly lucid, as within the author's prior books, … and the issues conscientiously chosen for max curiosity and elegance." — Martin Gardner.

This booklet is meant for those that cherished geometry after they first encountered it (and maybe even a few who didn't) yet sensed an absence of highbrow stimulus and puzzled what was once lacking, or felt that the play was once finishing simply whilst the plot used to be eventually changing into interesting.

In this magnificent therapy, Professor Ogilvy demonstrates the mathematical problem and delight available from geometry, the single specifications being basic implements (straightedge and compass) and a bit notion. fending off issues that require an array of recent definitions and abstractions, Professor Ogilvy attracts upon fabric that's both self-evident within the classical experience or really easy to turn out. one of the topics handled are: harmonic department and Apollonian circles, inversion geometry, the hexlet, conic sections, projective geometry, the golden part, and attitude trisection. additionally incorporated are a few unsolved difficulties of recent geometry, together with Malfatti's challenge and the Kakeya problem.

Numerous diagrams, chosen references, and thoroughly selected difficulties increase the textual content. furthermore, the valuable part of notes on the again offers not just resource references but additionally a lot different fabric hugely necessary as a operating remark at the text.

This publication is a consultant to the five Platonic solids (regular tetrahedron, dice, commonplace octahedron, common dodecahedron, and usual icosahedron). those solids are vital in arithmetic, in nature, and are the single five convex average polyhedra that exist.

issues coated contain:

- What the Platonic solids are
- The background of the invention of Platonic solids
- The universal beneficial properties of all Platonic solids
- The geometrical info of every Platonic good
- Examples of the place each one kind of Platonic sturdy happens in nature
- How we all know there are just 5 different types of Platonic good (geometric facts)
- A topological facts that there are just 5 different types of Platonic strong
- What are twin polyhedrons
- What is the twin polyhedron for every of the Platonic solids
- The relationships among every one Platonic strong and its twin polyhedron
- How to calculate angles in Platonic solids utilizing trigonometric formulae
- The courting among spheres and Platonic solids
- How to calculate the skin sector of a Platonic reliable
- How to calculate the amount of a Platonic strong

additionally integrated is a short advent to a couple different attention-grabbing different types of polyhedra – prisms, antiprisms, Kepler-Poinsot polyhedra, Archimedean solids, Catalan solids, Johnson solids, and deltahedra.

a few familiarity with easy trigonometry and intensely easy algebra (high college point) will let you get the main out of this e-book - yet so one can make this booklet available to as many of us as attainable, it does comprise a quick recap on a few worthy uncomplicated options from trigonometry.

This monograph goals to supply a sophisticated account of a few elements of dynamical structures within the framework of basic topology, and is meant to be used by means of graduate scholars and dealing mathematicians. even supposing many of the subject matters mentioned are particularly new, others should not: this e-book isn't a set of study papers, yet a textbook to provide contemporary advancements of the speculation that may be the principles for destiny developments.

This booklet includes a new conception built by means of the authors to accommodate difficulties happening in diffentiable dynamics which are in the scope of normal topology. To stick to it, the e-book offers an enough beginning for topological concept of dynamical structures, and comprises instruments that are sufficiently robust in the course of the book.

Graduate scholars (and a few undergraduates) with enough wisdom of easy basic topology, uncomplicated topological dynamics, and easy algebraic topology will locate little trouble in examining this publication.
