You have in your hands the most rigorous, complete and readable book ever written about the fascinating science of human sexuality. This book goes beyond the well-worn sexual education advice and the usual evolutionist psychology. After The Brain Snatcher, Pere Estupinyà comes back with the first popular science book on sex aimed at a wide audience. While there are some tips for the more adventurous, there is also a wealth of new information to be discovered. Distancing himself from the many books on advice or techniques, Estupinyà brings sex to another dimension by combining popular beliefs and science. Do you want proof that our decision-making in the “heat of the moment” is less rational than we think? Did you know that mind and vagina each go their own way? Are you interested in learning about the effects of yoga on sexual pleasure? Did you know about the attempts in the 60s to “cure” homosexuals with electric shock therapy, the chemical analysis of female ejaculation, or the fundamental relationship between the sympathetic and parasympathetic nervous system? The author has spoken directly with asexual and intersexual individuals, fetishists, multi-orgasmic women, women who never have orgasms through penetration, and men who have no refractory period. He has also participated in sadomasochistic events; learned tantric techniques with a couple of coaches, spoken with porn performers at Barcelona’s Bagdad, and attended workshops in which a woman teaches how to have orgasms with your mind and breathing. The result is an incredible miscellany of information that appeals to both the scientific community and the curious.

Outstanding text by one of the 20th century's foremost physicists dramatically explains how the central laws of physical science evolved, from Pythagoras' discovery of frequency ratios in the 6th century BC to today's research on elementary particles. Includes fascinating biographical data about Galileo, Newton, Huygens, Einstein and others. 136 illustrations.

Esta es la primera edicion critica en espanol del Tratado sobre la redondez de la Tierra, ensayo cosmologico y geografico nacido de la "ciencia infusa" (conocimento transmitido por la divinidad), atribuido a Sor Maria de Jesus de Agreda (Agreda, Soria, Espana, 1602-1665). Maria Coronel de Arana es posiblemente una de las figuras mas misteriosas y controvertidas de la Edad Moderna. No solo como personaje historico o literario, su vida y su obra reunen numerosos aspectos aun por descifrar que han dado lugar a una sugerente mitologia cultural de dimension transatlantica, abierta a sumar nuevas interpretaciones y significados. Figura politica, teologica y legendaria, Sor Maria de Jesus de Agreda se transforma en un significante cultural que no deja de acumular capas de sentido. Una de ellas, todavia poco explorada, es la atribucion del Tratado sobre la redondez de la tierra. Este volumen indaga en las razones para la atribucion a Sor Maria de Jesus, considerando su dimension de imagen cultural y transoceanica que rebasa la individualidad concreta. Tratamos diferentes aspectos de la vida, la obra, el contexto cultural y la tradicion desde la que se la leyo y puede leerse tambien en el siglo XXI. El Tratado se enmarca en el espacio de produccion cultural femenina conventual, sin el que no puede entenderse la figura de la autora, ni la escritura de mujeres en la epoca, no solo observando los generos mas conocidos del convento, sino una tradicion todavia por recuperar: la del conocimiento cientifico, que, aunque presente entre sus muros, apenas ha recibido atencion critica.

A fascinating tour of particle physics from Nobel Prize winner Leon Lederman. At the root of particle physics is an invincible sense of curiosity. Leon Lederman embraces this spirit of inquiry as he moves from the Greeks' earliest scientific observations to Einstein and beyond to chart this unique arm of scientific study. His survey concludes with the Higgs boson, nicknamed the God Particle, which scientists hypothesize will help unlock the last secrets of the subatomic universe, quarks and all--it's the dogged pursuit of this almost mystical entity that inspires Lederman's witty and accessible history.
