Journal ArticleDOI
TL;DR: In this paper, the authors discuss the classical axiomatic systems of Euclid and Hilbert, axiom systems for three and four dimensional absolute geometry and Pieri's system based on rigid motions.
Abstract: Discusses such topics as the classical axiomatic systems of Euclid and Hilbert, axiom systems for three and four dimensional absolute geometry and Pieri's system based on rigid motions. Models, such as Taxicab Geometry, are used to illustrate theory.

Journal ArticleDOI
TL;DR: The Lady or the Tiger? game as mentioned in this paper is a series of logic puzzles, ranging from the simplest problems to the most complex, where an array of imaginary characters pose questions to the players.
Abstract: \"The Lady or the Tiger?\" is a series of logic puzzles, ranging from the simplest problems to the most complex. An array of imaginary characters -- sane and insane vampires, psychiatrists, dreamers, hermits, kings, knights, knaves -- pose questions.
