Stephen Hawkings worldwide bestseller, A Brief History of Time, has been a landmark volume in scientific writing. Its authors engaging voice is one reason, and the compelling subjects he addresses is another: the nature of space and time, the role of God in creation, the history and future of the universe. But it is also true that in the years since its publication, readers have repeatedly told Professor Hawking of their great difficulty in understanding some of the books most important concepts. This is the origin of and the reason for A Briefer History of Time: its authors wish to make its content more accessible to readers as well as to bring it up-to-date with the latest scientific observations and findings. Although this book is literally somewhat briefer, it actually expands on the great subjects of the original. Purely technical concepts, such as the mathematics of chaotic boundary conditions, are gone. Conversely, subjects of wide interest that were difficult to follow because they were interspersed throughout the book have now been given entire chapters of their own, including relativity, curved space, and quantum theory. This reorganization has allowed the authors to expand areas of special interest and recent progress, from the latest developments in string theory to exciting developments in the search for a complete unified theory of all the forces of physics. Like prior editions of the bookbut even more soA Briefer History of Time will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space.

A menudo tenemos la sensación de que el azar gobierna nuestra vida, pero nos sorprenderíamos al descubrir hasta qué punto las cosas que nos ocurren obedecen a patrones menos arbitrarios. A CARA O CRUZ, el extraordinario libro de JEFFREY S. ROSENTHAL, explora los llamativos puntos de contacto entre la ciencia de las probabilidades y las aparentes casualidades de nuestra existencia. En efecto, este libro, traducido a casi una decena de idiomas, demuestra no solo que el calculo matematico es imprescindible para la investigacion cientifica, sino que una comprension adecuada del mundo de las probabilidades puede ayudarnos a resolver numerosas situaciones cotidianas y a tomar las decisiones mas acertadas.El prestigioso matematico JEFFREY S. ROSENTHAL aplica el calculo de probabilidades al estudio de la genetica, el comportamiento de los virus y la propagacion de enfermedades, y explora las fascinantes perspectivas que abre la fisica cuantica; pero tambien nos enseña a interpretar con ojo critico una encuesta de opinion o una estadistica, analizar las perspectivas que se dibujan en un diagnostico medico o en un plan de seguros, encontrar la mejor estrategia en los juegos de azar, evaluar la atencion que debemos prestar a nuestros temores mas arraigados o descubrir que se esconde detras de las coincidencias mas extrañas. Un libro apasionante que demuestra que el razonamiento matematico puede poner la suerte de nuestro lado.

Que algú vulgui fer-se pastor en l'era de la tecnologia no deixa de ser un fet curiós, però és una realitat d'ençà que l'any 2009 va néixer l'Escola de Pastors de Catalunya on s'han anat formant diferents promocions de joves amb una nova consciència, preocupada i ocupada a fer possible la vida a la terra, una vida que es nodreix no només dels aliments sinó de ser qui som. L'autora ha fet una transhumància per les vides d'aquests joves per saber qui eren, què els impulsava a retornar a la terra, quines eren les seves motivacions i els seus projectes vitals, com vivien i com ho vivien. Aquest moviment de retorn a la terra dels joves pastors es troba en un context global que ens fa entendre que el canvi que plantegen no és una bogeria sinó un anhel emmarcat dins un nou paradigma agrosocial. Tots tenen una convicció profunda que els fa aguantar ferms: la certesa de ser el motor de canvi d'uns nous temps.

WINNER OF THE ROYAL SOCIETY TRIVEDI SCIENCE BOOK PRIZE 2024ONE OF THE TIMES, SUNDAY TIMES AND NEW SCIENTIST BEST SCIENCE BOOKS OF THE YEARA HUGO AWARD WINNER FOR BEST RELATED WORK 2024THE INTERNATIONAL BESTSELLERTHE #2 MOST GIFTED BOOK IN THE SOLAR SYSTEMFrom the bestselling authors of Soonish, a brilliant and hilarious off-world investigation into space settlementEarth is not well. The promise of starting life anew somewhere far, far away - no climate change, no war, no Twitter - beckons, and settling the stars finally seems within our grasp. Or is it? Bestselling authors Kelly and Zach Weinersmith set out to write the essential guide to a glorious future of space settlements, but after years of original research, and interviews with leading space scientists, engineers and legal experts, they aren't so sure it's a good idea. Space tech and space business are progressing fast, but we lack the deep knowledge needed to have space-kids, build space-farms and create space nations in a way that doesn't spark conflict back home. In a world hurtling toward human expansion into space, A City on Mars investigates whether the dream of new worlds won't create a nightmare, both for settlers and the people they leave behind.With deep expertise, a winning sense of humour and art from the beloved creator of Saturday Morning Breakfast Cereal, the Weinersmiths investigate perhaps the biggest questions humanity will ever ask itself - whether and how to become multiplanetary.

Arlene KlotzkoSomeday soon (if it hasn't happened in secret already), a human will be cloned, and mankind will embark on a scientific and moral journey whose destination cannot be foretold. In A Clone of Your Own?, Arlene Judith Klotzko describes the new world of possibilities that can be More... glimpsed over the horizon. In a lucid and engaging narrative, she explains that the technology to create clones of living beings already exists, inaugurated in 1996 by Dolly the sheep, the first mammal cloned from a single adult cell. Dolly was the culmination of a long scientific quest to understand the puzzle of our development from one cell into a complex organism -- the outcome of a ' fantastic experiment' envisioned six decades before her birth. Scientists have since cloned mice, cows, goats, pigs, rabbits, horses, rats, a cat and a mule. Using the same laboratory tools and techniques, other researchers are trying to grow embryos, cloned from a single cell of a human being. Their goal is not to make copies of existing people, but to derive stem cells, the infinitely malleable raw material from which they hope to design therapies for currently untreatable diseases and the afflictions of old age. Our fascination with cloning is about much more than science and its extraordinary medical implications. In riveting prose, full of allusions to literature, psychology, art, music, and the cinema, Klotzko shows why the prospect of human cloning triggers our dearest hopes and especially our darkest fears, forcing us to ponder anew what it means to be human. And what it would be like to have 'a clone of your own'.
