Hartshome's fantastic book Geometry: Euclid and Beyond, and can be considered as a careful exposition of most of chapter II of that book. It must be remarked that non-euclidean geometries, i.e. geometries not satisfying the fifth postulate of Euclid, enter the scene, in a natural way, from the very beginning. The vast majority of plane geometry texts are only concerned with euclidean geometry, loosing the oportunity of not only teaching rigorous reasoning to freshmen, but at the same time exposing...

Si un gorila saltase de pronto a una cancha de baloncesto, te darías cuenta, ¿verdad? Si junto a ti se produjese un crimen violento, lo recordaría, ¿no es así? El gorila invisible es una apasionante, amena, rigurosa y muy divertida indagación en los increíbles pero cotidianos trucos que tu cerebro te engaña habitualmente.

This books objective is to facilitate the knowledge of the basic operations and to convert the immediate reference to understand and learn everything related to Algebra. Based on the fundamentals that the person that learns Mathematics thinks, analyzes, reasons, and, acting with logic, the book develops a practical 100% focus, that is to say, it approaches the theory with simplicity, and puts a greater emphasis on solving examples and verifying his learning by consulting the respective answers at the end of the book. You will also find a series of application problems that link mathematics...
