* Sabemos que utilizamos los números con bastante frecuencia. Algunos lo hacemos con seguridad, otros con cierta renuencia. Pero ¿somos conscientes de lo esenciales que resultan para casi todas las decisiones que tomamos? * Contar y medir cuando vamos de compras, viajamos, estudiamos o jugamos solo es el principio; las aplicaciones de los numeros son infinitas, desde la evaluacion de variables y el analisis de datos hasta las predicciones de la inteligencia artificial.* Este libro analiza las categorias de los numeros, la ciencia de la medicion, como funcionan las estimaciones y la visualizacion de numeros, acompañandole mas alla de los digitos hacia el mundo de la estadistica, la probabilidad, el riesgo y las ratios. Los numeros son nuestra manera de poner orden en el mundo, y cada uno de estos 50 temas solo utiliza 300 palabras y una ilustracion para darle una sensacion de control, ayudarle a comprender las tendencias en los datos estadisticos, como se utilizan los algoritmos y los metodos del aprendizaje automatico. Los numeros no le intimidaran nunca mas.

* Más de dos tercios de nuestro planeta están cubiertos de agua, pero ¿cuánto sabemos realmente sobre los océanos, su formación y su funcionamiento? * Sumérjase en este libro para descubrir por qué el mar es tan importante para la vida en la Tierra, ya que determina nuestro clima y acoge una abundante vida marina, y cual es el verdadero impacto de la contaminacion y el cambio climatico en este valioso recurso.* Se exploran los mares desde la superficie hasta el lecho marino, pasando por las olas, las plataformas continentales, los glaciares, los monzones y los arrecifes de coral. A lo largo de las paginas de este libro se abordan temas tan especificos como la radiacion solar, la contaminacion del mar, las peculiaridades de los principales oceanos del mundo y la amplia biodiversidad marina que albergan, desde el microscopico fitoplancton hasta la descomunal ballena azul. La acidificacion, la contaminacion plastica y el calentamiento global alteran y amenazan este ecosistema interconectado. De ahi la importancia de analizar la adaptacion que experimentan los procesos en el mar y como sera este en el futuro si no se detiene el cambio climatico.

Increasing numbers of urban dwellers has led to many of us feeling alienated from the natural world. This is not how we are meant to live, and we dont have to.

Green refuges and outdoor spaces are more important now than ever a break from our stressful, tech-consumed lives. It is well researched that being in nature radically improves our mental health, just minutes from your doorstep. Nature is waiting for us to discover it, even in the most urban environment. Go on a night safari, make a worm farm or create a one-pot allotment. With 200 smart illustrations, this practical and accessible guide will expand your horizons and increase your appreciation of wild spaces, whether on the street, in the park, or in nearby nature reserves. Chapters include: Be an Urban Naturalist: Go on a night safari, appreciate winter trees, spot moths or build a weathervaneEngage with the Elements: Wild swimming, mudlarking, barefoot walking and creating art with found natural objectsLook to the Skies: Cloudspotting, the dawn chorus and looking for murmurationsMake Space for Nature: Building for biodiversity, make a worm farm, green up all your spaceDig for Victory: Grow microgreens or create a one-pot allotmentFind Your Wild Tribe: Join a community garden, adopt a street tree or take a city hike

Death by Euphoria. Dysgenics. Population Death Spiral. Genetic Superhumans. Geomagnetic Reversal. Galactic Collision. Strangelets. Whether we like it or not, everythings going to come to a pretty unpleasant halt on our planet at some point in the future. What we dont know is what form our extinction is likely to take. In this accessible and entertaining book, acclaimed writer Alok Jha explains the head-spinning apocalyptic science behind 50 horrifying doomsday scenarios.

In a world where were bombarded with advice on going green, authors Mark Townsend and David Glick take a refreshing line and tell us how NOT to go green. Indeed, theyre here to help us f**k up the planet good and proper. And its easier than you think. An irreverent celebration of environmental doom and gloom, 50 Ways to F**k the Planet takes the eco-handbook in an outrageous new direction, exposing fifty very real and very scary threats facing the world today and showing just how entertaining and easy it is for us to make them worse. Forget the future. Why expend our energy on a lost cause? This is the defeatist (but not altogether unrealistic) stance taken by Townsend and Glick as they revel in the dire fate of our planet. Combining bleak facts with hilariously ironic commentary, the authors applaud our environmental incompetence and stick two fingers up at the whole damn thing. Punctuated with checklists and handy hints to f**k things up faster, this book is for those who want to stop pretending they are responsible world citizens and just get with the party. How much you get involved is up to you, but dont be fooled into thinking that doing nothing is any better. From the familiar honeybee, whose dwindling numbers have huge repercussions on our food chain, to the environmental implications of the smoking ban, the topics cover endangered species and declining terrain as well as social (mis)conduct and the devastating effects of commerce. Outspoken and unabashedly brazen, this is your ultimate countdown to the end of the world.

NASAs first successful mission to another planet, Mariner 2 to Venus in 1962, marked the beginning of what NASA Chief Scientist Jim Green describes in this volume as "a spectacular era" of solar system exploration. In its first 50 years of planetary exploration, NASA sent spacecraft to fly by, orbit, land on, or rove on every planet in our solar system, as well as Earths Moon and several moons of other planets. Pluto, reclassified as a dwarf planet in 2006, was visited by the New Horizons spacecraft in 2015. In this volume, a diverse array of scholars addresses the science, technology, policy, and politics of planetary exploration. This volume offers a collection of in-depth studies of important projects, decisions, and milestones of this era. It is not possible to foresee what the next 50 years of NASAs planetary exploration program will reveal. However, the 2020s are already looking promising. Planetary missions in recent years have focused more and more on exploring potentially habitable environments in our solar system and developing a more in-depth understanding of the evolution of planetary environments. It is safe to say that by 2062, our understanding of our solar system will be radically different than it is today. And we will look forward to it.

Este libro examina y discute los hallazgos más relevantes en biología de la reproducción en México. La biología de la reproducción es un campo extenso que estudia los procesos que regulan la generacion de nuevos seres vivos, la serie de cambios hormonales, conductuales y estructurales que acompañan a la diferenciacion sexual, a la pubertad, a la copula, al embarazo, la lactancia, al cuidado de las crias y al envejecimiento reproductivo. Ademas, esta disciplina examina las patologias asociadas con los procesos reproductivos, asi como los efectos de diversos contaminantes. En esta serie de trabajos se exponen temas muy variados que van de la anatomia, el desarrollo, los mecanismos implicados y las diferentes expresiones conductuales hasta la farmacologia, la toxicologia, el metabolismo y la regulacion neuroendocrina de la reproduccion. La Academia de Investigacion en Biologia de la Reproduccion (AIBIR) surge como respuesta a la necesidad de crear un organismo que estimulara y difundiera los hallazgos de investigaciones realizadas por cientificos mexicanos sobre este importante tema. La AIBIR, oficialmente constituida en 1975 por un grupo de expertos de renombre internacional, se ha mantenido vigente a lo largo de 50 años impulsando el conocimiento sobre la biologia de la reproduccion.
