Anarquía verde es una introducción lúcida y rigurosa a dos maneras opuestas de entender la libertad, la naturaleza y la revolución. Presenta el choque entre dos figuras clave del pensamiento anarquista contemporaneo: Murray Bookchin y John Zerzan. Marco Piracci reconstruye una polemica fascinante que atraviesa el anarquismo, el ecologismo radical, la critica al progreso y la forma de vida moderna.¿Ecologia o tecnologia? ¿Organizacion politica o contracultura? Lejos de simplificar, se da cuenta de un debate profundo, con aristas aun vivas en el ideario libertario. Una lectura indispensable para quienes quieran descubrir por que esta disputa esta marcando muchos de los dilemas politicos y ecologicos del presente.

Earth is askew, teetering ever-further into irreversible damage through the man-made climate crisis. Technology undoubtedly contributed to this mess, but its also a game-changer in our ability to fight it. Technologies that help to slash emissions and restore nature have the power to define tomorrows world, from low-tech biochar and enhanced rock weathering to the higher-tech processes of sucking carbon out of the atmosphere and using AI to increase energy efficiency.Through research and interviews with experts across the climate and technology spectrum, journalist Tasmin Lockwood explores these big ideas, innovations, and ways to roll them out equitably.Clean Up On Aisle Earth offers an optimistic blueprint of what life in a sustainable world could look like if we truly commit to it.

El cerebro: descifrando el enigma de nuestra humanidadEl cerebro es el órgano más enigmático del ser humano, un bosque de neuronas que da lugar a la cognición y al comportamiento. Este libro explora sus cuatro dimensiones fundamentales: el funcionamiento neuronal que nos hace humanos, la memoria como tesoro de nuestra identidad, la conciencia y su experiencia subjetiva, y los desafios del envejecimiento cerebral. Desde las tecnicas de Ramon y Cajal hasta la bionica cerebral moderna, estamos en el umbral de una revolucion que nos permitira romper los limites de nuestras capacidades naturales.

For more than four decades my work has followed a single thread: the search for patterns unifying life, intelligence, and the universe. From early recognition as Brazils youngest inventor to pioneering mobile payments, to my sabbatical in So Paulo where I used AI as my laboratory, the journey has been about connecting ideas across scales.Recent public versions include analysis of the Riemann zeta function (with 19 Standard Model parameters calculated), ANITA knot validation, CMB cosmology, and the bio-spacetime network. These converge in a unifying relation:dD/dt = (2) (t/S)Linking curvature, information flow, and complexity. Fractal dimensions across the neocortex (~1.7), protein folding (1.51.6), vascular networks (~1.8), and the tree of life (~1.82) confirm that living systems operate near the edge of chaos and order.In parallel, I advanced a working conjecture on the zeros of the Riemann zeta function, and released a public version demonstrating that the 19 Standard Model parameters long treated as empirical can be calculated. These are not slogans, but constructive derivations with explicit formulae and predictions. A private version provides axioms, theorems, proofs, falsifiability criteria, and simulation tools for researchers.This book begins from that foundation: intelligence is fractal repeating, evolving, and uniting mind, machine, and cosmos.

"Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things." Isaac Newtons The System of the World is the crowning achievement of one of the greatest minds in historya monumental exploration of gravity, motion, and the structure of the cosmos that forever changed the way humanity understands the universe.Originally written as the third volume of his Principia Mathematica, The System of the World distills Newtons revolutionary ideas into clear, elegant prose. In this masterwork, Newton explains planetary motion, the laws of universal gravitation, the movements of comets, and the forces that bind the heavens and the Earth under one unifying system.What sets this work apart is not only its groundbreaking science but also its visionary blend of reason, observation, and faitha view of the cosmos as both mathematically precise and divinely ordered.The System of the World remains a cornerstone of scientific thought, marking the birth of classical physics and inspiring generations of thinkers, from Einstein to Hawking. It is a profound testament to the human capacity for understanding the deepest mysteries of creation.

Many people want to run their own smallholding but wonder how easy it is and what exactly is involved. Free-range and Flourishing: The Smallholders Year offers valuable guidance to anyone seeking to embrace this aspect of rural life. Unlike farming, a smallholding doesnt require acres of land making it a far more accessible option. Author and smallholder Allison Lee provides hints and advice on growing fruit and vegetables, raising various animals, and encouraging wildlife. Drawing on her own experience she focuses on topics from choosing the right field shelters, fencing and equipment, to caring for donkeys, ponies, sheep, goats, pigs and chickens. Covering a year in the life of a smallholder, this book will encourage readers to be mindful of the seasons and enable them to understand the essential jobs that must be done all year round to keep livestock safe and healthy and the land productive.

El enamoramiento es un rasgo único de la especie humana. Nuestras habilidades para proyectar el futuro, comunicarnos mediante el lenguaje y producir pensamientos abstractos y complejos se alían con mecanismos mas primitivos y nos exponen a los flechazos. Muchas otras especies de mamiferos tambien saben lo que es desear y añorar a sus parejas, pero no llegan a trenzar una relacion tan compleja como los seres humanos porque sus cerebros no son tan sofisticados. El cerebro enamorado trata el amor desde una perspectiva cientifica: el placer, la reproduccion, la monogamia social, los tipos de vinculos, la ilusion de los primeros encuentros, el sexo, la estabilidad, la ruptura y su superacion. Entenderemos tambien que el enamoramiento es un comportamiento profundamente irracional. Cuando nos enamoramos, nuestro cerebro da luz verde a todas las decisiones relativas a nuestro objeto de deseo. Enamorarse consiste en algo parecido a convertir a otro individuo en una droga a la que engancharse. Basado en lo que la ciencia conoce sobre el enamoramiento, el libro sigue los avatares de una pareja que podriamos formar cualquiera de nosotros y nos permite comprender, de forma absolutamente apasionante, como funcionan el cerebro y toda su orquesta de neuronas y moleculas en semejante estado de enajenacion. Genetica y neurociencia contadas con rigor cientifico y suma inteligencia narrativa.
