For centuries, while men led governments and wrote political philosophy, women had little influence in democratic practice or thought. Starting in the 1980s, feminist ideas began to take center stage in the emerging debate about the nature of democratic politics. Models drawn from women's experiences and feminist thinking now constitute one of the most persistent and controversial themes in democratic theory. This volume brings together a selection of essential texts on the issue of feminism and democracy, written by the renowned American political scientist over the last four decades and edited by the specialist in her work, Felipe Rey Salamanca.

"I like amateur sports because it socializes, moralizes, produces human relationships, and brings forth an epic." With his characteristic benevolence, Boris Cyrulnik talks to us about the human condition through the lens of sports. As a major social phenomenon of the 20th century, he considers sports to be a magnificent field of reconstruction in which resilience, a concept popularized by the French neuropsychiatrist, finds an exemplary application. His anthropological approach leads him to hypothesize that the conventions of games were born with the advent of a child's awareness of others and the pleasure they would derive from measuring themselves against them. This form of "proto-sport" would be at the root of our evolution since the dawn of humanity.

After the flood ended and the water level dropped, all the animals had to be dispersed throughout the world. Noah stopped at the top of Mount Ararat and caused half of all the beasts plus one to disembark. He then headed for Everest, where he left half of his remaining animals plus one. He then arrived at Popocatépetl, at the summit of which he left half of the animals that remained on board plus one. He did the same on Kilimanjaro and left the last 10 on Mont Blanc. How many species of animals did he manage to save? This is a book to play while you learn to solve problems and do mathematical calculations or, if you prefer, to learn mathematics while you play. If you think that your knowledge is insufficient or that you have forgotten it over time, you are wrong! The purpose of Marie Berrondo Agrell lies in highlighting the playful part of solving any riddle and in infecting you with her foolproof enthusiasm.

How much mathematical knowledge can be stored inside a cube? Can we get an artistic work from any cube? Many researchers throughout history have been eagerly trying to find out. That mystery hides another mystery directly related to mathematics and the art of construction. We refer to the so-called golden number, section or golden ratio. Thanks to Doctor Matrix you will learn that from any two cubes it is possible to create a scale model of the Great Pyramid. It's amazing what can be salvaged from the seemingly dry mathematical science when a writer of the stature of Gardner motivates you to make works of art or teaches you how to cut three identical warped pyramids out of a simple cube. In this volume, the great popularizer creatively covers many other aspects of mathematics, such as Wizard's alphabetic symmetry (referring to The Wizard of Oz) or Alan Wayne's arithmetic cryptograms. Your reading will forever change the reserved attitude that we generally show towards this discipline.

Few things have stimulated the imagination as much as infinity! It has all sorts of curious properties that at first seem paradoxical, but later turn out not to be. As such, it provides material for a book of brain teasers and paradoxes. The Witcher and his two young apprentices Annabelle and Alexander offer you a guided excursion through infinity here. They will visit, for example, an island where talking robots create other intelligent robots and program them to create more robots, which in turn create new intelligent robots and so on, ad infinitum. Through stories like this one, in addition to entertaining yourself with mathematical challenges, you will be able to learn about the pioneering discoveries of the great German mathematician and philosopher Georg Cantor. The Sorcerer, in typical humorous style, ends with a delightful tale of how Satan himself was tricked by a cunning student of Cantor. Even the neophyte will be able to understand the nature of infinity, Cantor's astonishing contribution (he was the first to put the subject of infinity on a logically sound footing), and a description of what might be the greatest mathematical problem of all time that, even today, still no solution!
