Un testimonio que, desde la mirada de un veterinario, nos muestra cómo los animales dan sentido a nuestras ciudades...y a nuestras vidas.En teoría, las ciudades somos nosotros: humanos acelerados, con ojeras de mapache y el movil pegado a la mano. Pero si afinamos un poco la mirada, como haria un pajaro al posarse en la rama de un arbol, descubrimos algo evidente y a la vez olvidado: no estamos solos.Entre el asfalto y las prisas viven millones de criaturas. Y, en medio de todas ellas, hay un veterinario que convive cada dia con historias pequeñas y enormes a la vez: esas en las que los animales no solo comparten piso, sino que rescatan vidas, calman ansiedades y sostienen duelos con una lealtad que no entiende de etiquetas.Las familias que llenan nuestros hogares ya no son exclusivamente humanas, no, son multiespecie. Humanos, gatos, perros, periquitos, tortugas y hasta ratas con mas habilidades sociales que muchos de nuestros vecinos.Con humor y emocion, Animales de ciudad te invita a adentrarte y explorar la diversidad de la vida, recordandote lo que intuias pero no decias en voz alta: la sociedad no la formamos solo los humanos... y menos mal.Una celebracion del caos urbano, de sus habitantes peludos, emplumados y escamosos, y de como, cuando todo se tambalea, a veces quien te salva la vida ni siquiera sabe hablar.

A NEW, FULLY ILLUSTRATED EDITION OF ANDREW MAYS ILLUMINATING GUIDE TO LIFE NOT ON EARTHThe possibility that alien life exists in the universe is among the most profound of human conjectures, which today is being investigated not just by science-fiction writers but by scientists.Astrobiology presents an expert guide to this compelling field of science. It shows how the tell- tale signatures of life on Earth might hold the key to detecting life beyond our planet; explores the many planets beyond our Solar System discovered by NASAs Kepler and TESS missions; and explains alien- hunting touchstones such as Fermis Paradox, the Drake Equation, and the Wow signal.As NASAs rovers burrow into Mars and its probes peer ever further into the cosmos, this illustrated edition combines deep space images with infographics to cast a scientific eye over the most significant of scientific treasure hunts.

Nature artist Jane Smith has been fascinated by wildlife communities and ecosystems her whole adult life. Starting from her own garden in Argyll, she travels to ten locations in the west of Scotland - from the towering cliffs of St Kilda and the peatlands of Lewis to the Solway estuary and the urban sprawl of Glasgow - to explore the interaction of people and wildlife in a variety of diverse settings. On her journey she discovers a number of communities who are taking on the job of regenerating their own landscapes and meets a host of fascinating people whose lives are inextricably bound up with questions of sustainability, conservation and landownership. Contents Includes: Western Isles (peatlands) * North Uist (machair) * Islay (farmland) * Loch Arkaig (woodland) * Knapdale (wetland) * Dumfries and Galloway (river and estuary) * Jura (coast) * St Kilda archipelago (sea) * Glasgow (urban landscapes) *Eigg (community ownership)

Un enfoque fresco y divertido para entender cómo la física puede salvarnos del fin del mundo.¿Y si el fin del mundo no es una metáfora, sino un problema físico?¿Y si la solución no es solo política, sino cientifica?¿Y si entender como funciona el universo es nuestro mejor plan de supervivencia?La vida en la Tierra es, seamos sinceros, una rareza estadistica de proporciones galacticas. Habitamos una roca que flota en la nada, calentada por una bola de fuego a la que no podemos acercarnos y gobernada por leyes fisicas que no descansan ni en festivo. Y, aun asi, este absurdo cosmico es precisamente lo que podria ayudarnos a evitar nuestro propio fin del mundo.Porque antes de preocuparnos por lo que viene, necesitamos entender el escenario en el que todo ocurre: que fuerzas sostienen el universo y que sucede cuando las ignoramos.Esto no es un sermon ecologista ni una profecia apocaliptica. Es una invitacion a mirar nuestro planeta -este improbable oasis azul- con nuevos ojos. Y a entender que, si queremos tener un futuro, antes debemos comprender el tablero en el que jugamos.Leo Olivares, creador de la cuenta @ciencia_radiactiva, y Marc Mesa, experto en fisica, nos guian en un recorrido desde el Big Bang hasta el cambio climatico, explorando los limites mas incomodos de la energia y la materia a traves de paradojas cotidianas y las grandes crisis que definiran nuestro destino.La buena noticia: tenemos el conocimiento.La mejor noticia: aun estamos a tiempo.La fisica ya nos señala el camino. Solo falta que aprendamos a seguirlo.

Los Elementos de Euclides es una de las escasísimas obras antiguas que puede presumir de haber constituido, casi de golpe, la base sobre la que se ha levantado toda una ciencia, en este caso la geometria y la aritmetica, al menos desde el siglo III a. C. hasta el siglo XIX. La razon de su prolongado exito radica en sus grandes virtudes expositivas y didacticas, asi como en su afan de sistematizacion deductiva.Gredos publica esta obra completa de Euclides en tres volumenes y en una exhaustiva edicion critica. En este primer tomo (libros I-IV), el matematico griego desarrolla la teoria de la geometria plana.

La historia íntima de cómo un joven científico cambió para siempre nuestra forma de conectarnos al mundoEn 1989, en una pequeña oficina del CERN, un joven científico británico concibió una nueva forma de compartir informacion. Se llamaba Tim Berners-Lee, y de aquella intuicion nacio la World Wide Web, una herramienta que transformo para siempre la manera en que trabajamos, nos comunicamos y nos relacionamos con el mundo.En estas paginas, Berners-Lee cuenta por primera vez, de forma intima y directa, como se gesto la web: desde el primer servidor improvisado hasta la expansion mundial de una idea que hoy sostiene la vida cotidiana de miles de millones de personas.Sin embargo, este libro es mucho mas que unas memorias: es tambien un lucido analisis de los dilemas a los que se enfrenta internet en un presente marcado por la concentracion del poder en manos de unas pocas plataformas, la explotacion a gran escala de nuestros datos personales y la irrupcion de la inteligencia artificial.Con la autoridad de quien estuvo en el origen de todo, Berners-Lee advierte de los riesgos de un futuro gobernado por algoritmos opacos y corporaciones sin control democratico. Al mismo tiempo, nos propone una hoja de ruta para recuperar la web como un espacio de creatividad, colaboracion y libertad, fiel al espiritu que la inspiro.

An island without a harbour, encircled by perilous cliffs and rising high above the wild Atlantic ocean, farmed by the same family for eight generations. What is it like to live at the edge of the world?In this marvel of quiet reflection and keen observation, Tim Ecott takes the reader to Stora Dimun - an isolated island farm in the Faroe Islands with only two permanent residents. He finds a remarkable way of living; one where youre isolated but never truly alone, surrounded by remarkable wildlife and an ever-changing landscape. On the island, every day is spent breathing fresh air, managing your livestock and continuing the work begun by your forebears hundreds of years ago. Here, time blurs - technology may encroach, but traditions are engrained.Tracking the rhythm of the year and the challenges of life on this island, this book is a celebration of both the human spirit and our relationship with the natural environment. It is about sustainability, resilience and how to survive and adapt when the world is rushing headfirst into a digital future of artificial intelligence and anonymous food chains. Evas Island is a call to anyone who has ever dreamt of a life on an island of ones own.

Gods Providential Work in Creation Before Life Began God has been present and active in creation from the moment he created it ex nihilo. Few Christians would question this claim, but its implications for ongoing theology and science dialogues have not been fully explored.In this pathbreaking and field-advancing work, Ross Hastings brings his expertise in both scientific and theological disciplines to bear on the topic of divine providence in chemical evolution. Based on the latest research in the developing field of chemical evolution and the work of theological giants such as Karl Barth, Hastings shows how God may have been providentially and non-competitively at work in the process by which simple prebiotic molecules gave rise to the complex molecules in the first living organisms.In God and Molecules, Hastings provides cutting-edge theological engagement with the developing scientific field of chemical evolution, advances the discussion in theology and science with this new integrative work, and offers a holistic alternative for thinking about chemical evolution that overcomes the binary of theology versus science. God and Molecules pushes toward new frontiers in theology and science and casts a compelling, integrative, and ultimately healing vision for how God has been lovingly involved in the developmental process of the earliest life on earth.

Excellent Aaron BastaniEvery leader comes to power promising growth: think back to the campaigns of Boris, Truss, Sunak, Starmer, Trump. Yet real-term income hasnt improved in the UK since 2008. Across the West, growth has stagnated for well over a decade, leading to cost of living crises, political instability and rising social tensions.Is real economic growth still possible? And with the climate emergency accelerating beyond repair, should we still be pushing for it?In Icarus Economics, acclaimed economist John Rapley argues that the problem of growth is inherently tied up with the climate crisis. We often assume that poor countries will bear the brunt of climate change, pandemics, and other exogenous shocks, but this book argues the opposite: western societies have more wealth and capital to lose and are less inherently resilient. In this book, he shows us how rich countries can grow their own economies by helping poor countries to decarbonise - and in the process, mitigate the effects of climate change.

What if the world around us is far richer than we can perceive? In Invisible Rainbows, astrophysicist and science communicator Dr Alfredo Carpineti reveals the extraordinary hidden universe beyond the limits of human vision and how we have learnt to harness it. From the emanations of powerful cosmic explosions in gamma-rays to galaxies glowing in radio waves, he shows how every colour we see is just one note in the vast symphony of light. Featuring conversations with LGBTQIA+ astronomers and scientists from around the world, Carpineti focuses on their pivotal but often invisible contribution to the evolving field of astronomy, and how our identities can shape the way we look at the universe. Blending awe-inspiring science with reflections on perception, diversity and wonder, Invisible Rainbows changes the way we see ourselves and the cosmos.

Una impactante colección de historias y personajes que se mueven en los límites del mundo y de la cordura.Antes de que su nombre se convirtiera en una referencia ineludible para pensar las grandes preguntas de la ciencia y sus relaciones con el vertigo, la destruccion y la locura, Benjamin Labatut escribio La Antartica empieza aqui, su primer libro, una coleccion de cuentos que contenia, en estado larvario, las obsesiones que iban a marcar su literatura posterior.Publicados originalmente en 2010, y revisados por el autor para esta nueva edicion, los cuentos presentan historias en las cuales la realidad se descompone y la experiencia humana se vuelve extraña. Seis narraciones atravesadas por una sensacion de amenaza difusa y de violencia latente en las que una decision minima lo puede trastornar todo. Algo se quiebra sin estruendo: una certeza, una relacion, una identidad. Aqui, la Antartica, mas que un lugar o un destino fisico, es una frontera: el limite tras el cual se encuentra la muerte o la revelacion, el umbral donde el lenguaje comienza a fallar y el ser humano se expone a su enorme fragilidad.Ya en su primer libro, Labatut demuestra una sensibilidad capaz de sugerir abismos sin necesidad de mostrarlos, y nos arrastra a una zona donde la amenaza del colapso es total. Leido hoy, este volumen adquiere un valor especial: no solo es el punto de partida de una de las voces mas singulares de la literatura actual, sino que permite conocer el mito de origen de un autor que interrogara, con una lucidez implacable, los bordes del mundo y de la mente. Porque en sus paginas late la pregunta que anima toda su obra: ¿que ocurre cuando el ser humano se aproxima demasiado a lo que no puede comprender?La Antartica empieza aqui no ofrece respuestas, pero deja una huella persistente: una sensacion de frio extremo que permanece en el lector mucho despues de haber alcanzado la ultima pagina.
