A atual crise ambiental e social demanda uma reflexo a respeito do estado vigente do mundo. Nosso atual modelo economico, caracterizado pelo uso indiscriminado de recursos, em um processo constante de extraço, produço, uso e descarte, se mostrou ineficiente, trazendo consequencias diretas a vida no planeta. A sociedade, ao passo que esta interligada a natureza, tem o poder de modifica-la, gerando impactos que podem ser encarados como problemas sociais. Este livro, partindo de uma perspectiva teorica da economia ecologica, buscou discorrer sobre a economia circular, apontando-a como um movimento economico alternativo, que pode contribuir para a reduço dos impactos ambientais e sociais, possibilitando um cenario de mais equidade e bem-estar social.

Un viaje esperanzador por la capacidad de la naturaleza para adaptarse que nos enseña a enfrentar los desafíos actuales. Durante casi cuatro mil millones de años, la vida en la Tierra ha encontrado nuevas formas de adaptarse, reproducirse y prosperar, transformandose para responder a las condiciones de cada epoca. Pero el impacto humano sobre el planeta y la amenaza potencialmente devastadora del cambio climatico han puesto a prueba esa capacidad de adaptacion como nunca antes. Aun asi, la vida siempre encuentra un camino. Animales, plantas e insectos siguen afrontando el desafio y continuan adaptandose, reproduciendose y prosperando incluso en un entorno en rapida transformacion. En su ejemplo quiza encontremos tambien nosotros las claves para cambiar, para detener la destruccion que estamos causando al planeta.En El ingenio de la naturaleza, David Farrier nos invita a un viaje profundo por este mundo natural en constante cambio. Lo que descubrimos en el podria transformarnos. Las formas en que los animales se ajustan al paisaje urbano pueden ayudarnos a diseñar ciudades sostenibles. El estudio de otras inteligencias puede inspirarnos a reinventar nuestras economias. La evolucion bacteriana puede ofrecer soluciones al problema de los residuos. La biologia sintetica podria rescatar especies al borde de la extincion. Y pensar en las escalas de tiempo de la naturaleza puede guiarnos hacia un futuro mejor.La vida en la Tierra esta cambiando; la pregunta es si nosotros seremos capaces de cambiar con ella. ¿Podremos reconstruir el mundo para que toda forma de vida vuelva a prosperar?

¿Que sintieron los grandes cientificos de la historia en el momento en que alcanzaron sus grandes descubrimientos? ¿Como llegaron al instante magico en el que sus predicciones se hicieron realidad? Este increible viaje de la prediccion a la prueba nos transporta desde laboratorios ubicados en Paris y Cambridge hasta el frente ruso devastado por la guerra, pasando por bunkeres construidos bajo reactores nucleares y enormes tuneles subterraneos en la frontera suizo-francesa. Desde el electromagnetismo hasta las ondas gravitacionales de Einstein y el escurridizo neutrino de Wolfgang Pauli, el aclamado escritor y cientifico Marcus Chown nos acompana en un recorrido impresionante por los avances de la fisica moderna, deteniendose en ese instante magico en el que las matematicas y la fisica, de la mano de sus mas brillantes representantes, cambiaron para siempre la historia de la ciencia.

Un alegato brillante contra el antropocentrismo que revela un planeta lleno de inteligencias y culturas más allá de la humana.Darwin consideraba que los seres humanos formamos parte de la red de la vida, no la cuspide de una jerarquia natural. Sin embargo, hoy muchos siguen convencidos de que somos la especie mas inteligente, virtuosa y exitosa que ha existido. Este pensamiento erroneo nos permite explotar la Tierra en beneficio propio, llevandonos a un peligroso desequilibrio planetario. Pero ¿es inevitable esta vision y forma de vida? El mono arrogante demuestra que el excepcionalismo humano es una ideologia que depende mas de la cultura que de la biologia, mas de la ilusion y la fe que de la evidencia.Christine Webb, primatologa de Harvard, lleva años investigando las ricas vidas sociales, emocionales y cognitivas de nuestros parientes mas cercanos. Pone al descubierto los sesgos con que muchas investigaciones cientificas juzgan a otras especies y revela la complejidad a menudo ignorada del mundo no humano: desde el lenguaje de los pajaros cantores y los perritos de las praderas hasta las culturas de los chimpances y los peces de arrecife, o la sorprendente inteligencia de las plantas y los hongos. Con relatos fascinantes y nuevas investigaciones, nos ofrece una perspectiva transformadora para comprender a otros seres vivos en sus propios terminos, una vision que esta revolucionando nuestra manera de entender tanto a los demas como a nosotros mismos.Las criticas al excepcionalismo humano suelen centrarse en nuestra obligacion moral hacia las demas especies, pero olvidan lo que tambien podriamos ganar si desmontamos nuestras ilusiones de singularidad y superioridad. Este cambio de perspectiva nos llena de asombro y satisface uno de nuestros deseos mas profundos: el de pertenecer al gran conjunto del que formamos parte. Lo que esta en juego es una forma de vida mejor y sostenible, con el potencial de sanar y regenerar nuestro planeta comun.

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.

Energy is Life: Why Environmentalism Went Nuclear follows Zion Lightss personal and powerful journey: from grassroots green activism to becoming one of the UKs leading advocates for nuclear energy. In a time of climate crisis, energy poverty and growing demand for clean power, she examines why long-established environmentalists like herself once feared nuclear energy, why many have since come to embrace it, and makes a compelling case for why nuclear energy must be part of the solution. Accessible, evidence-based, and deeply human, this book challenges common myths and invites readers to rethink what it really means to care for people and planet alike. If you believe in a greener, fairer future, this book just might change your mind and give you hope.

"De cegueira em cegueira, eliminamos tanta vida do nosso horizonte intelectual que, no fim, ficamos sozinhos." Em Fitópolis, o neurobiólogo e botânico italiano Stefano Mancuso propõe uma transformaçã

Exceptional intellectual and creative achievement has often coexisted with psychological distress, but the relationship between genius and mental illness is more complex than romantic narratives suggest. This comprehensive examination explores how historical figures of extraordinary accomplishmentscientists, artists, composers, writers, and mathematiciansnavigated mental health challenges while producing transformative work, analyzing both the biographical evidence and the cultural myths surrounding creative genius.Drawing on personal correspondence, medical records, biographical accounts, and psychological research, this book reveals how individuals managed depression, anxiety, bipolar disorder, and other conditions within their historical contexts. It explores how mental distress sometimes influenced creative work, how social isolation enabled or hindered productivity, and how contemporary understanding of mental illness shaped how genius was perceived and treated. The narrative examines support systems that enabled continued work, the role of institutions in helping or harming exceptional individuals, and how economic security affected outcomes.Each profile analyzes the specific nature of their achievements, the documented evidence of mental health struggles, and how later generations romanticized or stigmatized their conditions. It addresses the myth that suffering produces genius, the reality that many struggled despite their talents rather than because of them, and how better mental health support might have extended productive lives. This work provides rigorous analysis grounded in historical evidence rather than mythology about tortured genius.

In 1991, eight "biospherians" were sealed inside a three-acre glass terrarium in the Arizona desert. Biosphere 2 contained a rainforest, an ocean, and a savannah. It was meant to prove that humans could colonize Mars. Instead, it proved how little we understand Earth. Oxygen levels plummeted, crops failed, the crew split into warring factions, and crazy ants exterminated the other insects."The Glass World" documents the most ambitious ecological experiment in history. It details the scientific hubris, the psychological strain of isolation, and the humbling realization that we cannot engineer a replacement for nature. A crucial read for the climate change era, showing that "Planet B" is much harder to build than we think.
