In every way a beautiful book. Sebastian FaulksWhen novelist Anuradha Roy and her husband stumble upon a derelict cottage in the hill station of Ranikhet, they decide it is where they will now live. After the frenetic city of Delhi, Roy is initially bemused by the gentle pace of life in the mountains but then won over: spellbound by the landscape, taken to the heart of their sometimes recalcitrant neighbours and adopted by four mountain dogs and counting. Over twenty-five years, as she becomes accustomed to living among forests where leopards roam freely, she will come to encounter nature at its most fierce, captivating and vulnerable and bear witness to the destructive impact of global warming on the alpine ecosystem.Written with unsentimental clarity, humour and poignancy, Called by the Hills: A Home in the Himalaya is a tender and intimate portrait of a home, a community and a rugged, extraordinary landscape.

Hemos complicado demasiado el estudio del Pasado, dando mayor importancia a puntos de vista, intereses nacionalistas, religiosos y morales, que colocan el hecho histórico en segundo lugar, subordinado al interes del sistema que pretende educarnos. Llego la hora de simplificar y demostrar respeto hacia nuestros ancestrales, esforzandonos en conocer lo que realmente sucedio en el pasado, y no apenas aquello que el sistema pretende informarnos. Despues de tantos años estudiando Historia, llegue a la conclusion de que la mejor forma de conocer el pasado es a traves de una Cronologia imparcial, objetiva, que se limite a colocar cada acontecimiento en su exacto lugar en el tiempo, revelando la Historia sin manipulaciones ni medias verdades. Esta Cronologia constituye un completo material de consulta, no apenas con hechos puramente politicos, como fundacion de ciudades, nacimiento de reinos e imperios, descubrimientos cientificos y geograficos, desastres naturales y epidemias, sino tambien conteniendo informaciones sobre los mas diferentes campos de la actividad humana: quimica, astronomia, geografia, matematicas, etc. De forma paralela, la obra es complementada por datos que no pertenecen a una fecha determinada, sino a toda una epoca, son generalidades de cada sociedad, curiosidades, costumbres, la religion de cada civilizacion, inventos sin fecha exacta, etc. El resultado de todo este conjunto es una de las mas completas cronologias existentes, periodicamente actualizada con los ultimos descubrimientos arqueologicos y cientificos. Una obra de esta magnitud no podria ser publicada en un unico libro, por eso la he dividido en varias colecciones, y los originales en español estan siendo traducidos para frances, ingles, aleman, italiano y portugues. La cronologia transcurre año a año, dentro de lo posible, desde la prehistoria hasta la actualidad. Para aquellos que prefieren un estudio mas profundo y detallado, he preparado una segunda cronologia, dia a dia, que abarca desde 1789 hasta 1946, dividida en cuatro colecciones.

"The book that defined how the world works."In The Mathematical Principles of Natural Philosophy, Isaac Newton didnt just explain how things move; he provided the mathematical proof for the mechanics of the entire universe. Moving beyond the speculative theories of his predecessors, Newton used rigorous geometric proofs to establish his Three Laws of Motion. From the falling of an apple to the orbits of the planets, he demonstrated that the same physical forces apply everywhere. This masterwork transformed the study of nature from a branch of philosophy into the modern discipline of physics, forever changing our understanding of space, time, and force.The Law of Universal Gravitation: Newtons most famous contribution within these pages is the derivation of the inverse-square law of gravity. He proved that every mass in the universe attracts every other mass, providing the first coherent explanation for why the moon orbits the Earth and why the planets remain in their paths around the sun.A Triumph of Mathematical Logic: Though Newton had developed calculus (which he called "fluxions"), he wrote the Principia using classical geometric proofs to ensure his contemporaries could follow his revolutionary logic. The result is a work of staggering intellectual density that remains the gold standard for scientific inquiry.Why It Is Essential: To own the Principia is to own the spark of the Scientific Revolution. It is the bridge between the ancient world and the space age, a testament to the power of the human mind to decode the hidden laws of nature.Own the foundation of modern science.

Zetetic Astronomy: Earth Not a Globe! assembles experiments, anecdotes, and vignettes to argue that Earths surface is planar, circled by an Antarctic ice barrier, and roofed by a nearby, circling sun and moon. Written in forthright Victorian prose, the treatise privileges everyday sight over mathematical abstraction, invoking canals, horizons, and perspective to counter Newtonian cosmology. Interleaving diagrams with courtroom-like cross-examinations of navigators and astronomers, it positions its zetetic method - inquiry before hypothesis - within the bustling culture of nineteenth-century popular science and public lecturing. Parallax was the pen name of Samuel Birley Rowbotham, an itinerant English lecturer and autodidact whose observations along the Bedford Level fens convinced him that orthodox astronomy misstated observable reality. Moving among working-class debating societies and dissenting circles, he cultivated suspicion of elite expertise and a zeal for repeatable demonstrations, which shaped both his teaching and this defiantly empirical book. Recommended to readers of the history and sociology of science, this volume is a primary source in the rhetoric of counter-science. Read it alongside contemporary astronomical manuals: its provocations illuminate how authority, evidence, and spectacle intertwined in the Victorian marketplace of ideas, and still animate public reasoning today.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

Submerged Forests distills coastal observation into a rigorous synthesis, tracing drowned tree stumps and peat beds that fringe Britains shores. From case studies of rooted stumps in situ within peat and estuarine silts, Reid reconstructs post-glacial shoreline migration and sea-level change, using stratigraphic sections, plant macrofossils, and occasional artefacts to date phases from late Pleistocene to early Holocene. Written in measured, lucid field prose, it situates coastal peats within debates on eustasy, isostasy, and marine erosion. Clement Reid, geologist and palaeobotanist with the Geological Survey of the United Kingdom, brought a rare synthesis of botanical acuity and coastal mapping to the subject. Collaboration with Eleanor Mary Reid on fossil seeds honed his capacity to read peat deposits as time-series. Years on the Cromer Forest-bed and receding shores supplied the empirical foundation, and his interest in Britains former land connections framed the books broader inferences. This classic rewards geologists, archaeologists, and environmental historians seeking a clear, data-rich account of Holocene shoreline change. It remains an exemplary model of how to build large narratives from humble evidence. Read it for its method: a concise, lucid lesson in making landscapes speak across deep time.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

First published in 1876, this two-volume treatise codifies the worlds fauna into six zoogeographic realms: Palearctic, Nearctic, Neotropical, Ethiopian, Oriental, and Australasian, and explains their boundaries through geology, climate, and barriers to dispersal. Wallace integrates exhaustive catalogues with interpretive chapters, using maps, synoptic tables, and bathymetric clues such as shallow seas to infer past connections. Extending P. L. Sclaters avian scheme to vertebrates, his methodical prose offers a Darwinian, historical account that makes biogeography a synthetic science. Wallaces argument grows from lived experience. Years in the Amazon and the Malay Archipelago, where he traced the Wallace Line between Bali and Lombok, gave him intimate knowledge of island faunas, endemism, and migration barriers. As co-formulator of natural selection and an indefatigable collector for museums, he turned field notes, specimen lists, and correspondence with Darwin, Huxley, and Sclater into a principled framework for why species occur where they do. Scholars of evolution, macroecology, and the history of science will find this foundational synthesis indispensable; conservationists and systematists will value its durable logic and global scope. Read it for empirical rigor and conceptual clarity: a master class in converting natural history into theory, and in learning to read the map of life.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

In Pursuit of Spring (1913) follows Edward Thomass bicycle ride from London to the Quantock Hills of Somerset as winter loosens. In lucid, finely cadenced prose, he records lanes, hedgerows, inns, birdsong, weather, and place-names, blending topographical exactitude with lyrical restraint. Set within the English peripatetic tradition of Cobbett, Borrow, and Jefferies, the book also registers the modernroads, telegraph wires, the bicycle itselfwith poised ambivalence, reading the countryside as both archive and living present. Thomas (18781917), a London-born critic of Welsh parentage, had long written about the countryside while burdened by hackwork. Walking and cycling were his release; soon after this journey, friendship with Robert Frost would usher his turn to poetry. His love of maps and place-names, and his minute knowledge of birds and rural labor, shape the books inquiry into language, memory, and belonging. For readers of nature writing, travel literature, and the environmental humanities, this is a quietly bracing companion: attentive, unsentimental, and restorative. Whether cyclist, walker, or armchair traveler, you will find a luminous meditation on how to see a landscape in time, and why such seeing matters.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

Electricity and Magnetism, a volume in Elisha Grays Natures Miracles series, offers a lucid, apparatus-centered tour of charge, current, induction, and magnetic action. Interweaving historical vignettesVolta, Faradays lines of force, Maxwells field picturewith plainspoken demonstrations and crisp woodcuts, Gray moves from benchtop effects to power stations. Eschewing heavy mathematics, he shows how dynamos, transformers, telegraph circuits, and early telephones enact the same field laws, exemplifying late nineteenthcentury popular science at its best: empirical, practical, and democratically didactic. An accomplished electrical engineer and prolific inventor, Gray co-founded the firm that became Western Electric, created the harmonic telegraph and telautograph, and famously contested priority in the invention of the telephone. Trained at Oberlin and seasoned in shop and laboratory, he writes with a practitioners economy and a teachers patience, translating workshop intuitions into household-scale experiments. The books emphasis on applications and on FaradayMaxwell concepts betrays a life spent bridging patent office, factory floor, and lecture hall, and a desire to make the new electric age intelligible to non-specialists. Recommended to general readers, educators, and historians seeking a clear, context-rich primer that complements mathematical treatises and captures electrification at the moment it entered everyday life.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

Micrographia (1665) opens a vast new world by recording, in crystalline prose and sumptuous copperplates, the textures and structures of minute bodiesflea and louse, bee-sting and feather, mold, needle point, and the honeycombed cork in which Hooke first named the cells. Organized as a sequence of observations with reflective Inquiries, the book marries measurement with speculation, and sets the Baconian ideal of experiment within the visual rhetoric of the Scientific Revolution. Its dramatic fold-out plates and patient, calibrated descriptions forged a language and iconography for early microscopy. Robert Hooke, polymath Curator of Experiments to the nascent Royal Society and longtime collaborator of Robert Boyle, brought to this work a craftsmans intimacy with instruments and a philosophers appetite for causes. His refinements in lenses and illumination, his habit of daily experiments, and his duty to stage public demonstrations all fed the project; so too did his draughtsmans hand, which translated observation into authoritative image and argument. Readers of science, art, and intellectual history will find Micrographia indispensable: a foundational statement of modern empiricism and a gallery of the unseen. Approach it to witness method at work, to savor disciplined wonder, and to grasp how tools and images re-make knowledge.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

In Beaver World is Enos A. Millss intimate natural history of Castor canadensis, distilled from years of patient vigils beside mountain streams. Chapter by chapter he unfolds the beavers life cycle, social organization, and architectural craftdams, lodges, canalslinking each to seasonal rhythms and risk. His prose couples anecdote with measurement and plain exposition, situating the beaver as a keystone engineer whose hydrologic works expand wetlands and diversify habitat. The result is a narrative that anticipates ecosystem ecology while remaining rooted in vivid field scenes and the cadence of early twentiethcentury American nature writing. Mills, a Colorado naturalist, guide, and key advocate of Rocky Mountain National Park, wrote from a life embedded in the high country. Managing a lodge and leading expeditions, he kept notebooks on nearby colonies through droughts and wintersexperience that grounds his plea to recognize beavers as conservators of water and soil. Scholars of environmental history, field naturalists, and readers curious about nonhuman engineers will find the book instructive and restorative. It is recommended for those engaged in watershed restoration, rewilding, or climate adaptation, and for general readers seeking lucid, humane science writing with enduring practical relevance.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

The Natural History of Selborne (1789) assembles Gilbert Whites decades of field notes into an epistolary chronicle addressed to fellow naturalists Thomas Pennant and Daines Barrington. Through lucid, quietly lyrical prose, White records the seasonal pulse of a single English parishits birds, insects, plants, soils, and weathermarrying patient empiricism with pastoral attentiveness. His long-term observations on swallow migration, the habits of earthworms, and the harvest mouse exemplify a proto-ecological method grounded in place. Situated within Enlightenment natural history, the book helped pivot the discipline toward attentive, longitudinal, local study. A country clergyman educated at Oxford, White spent most of his life in Selborne, Hampshire, ministering to his parish while tending gardens and keeping meticulous journals. His correspondence with leading savants, daily walks and weather logs, and deep familiarity with the Hanger and Common fostered a modest, exact observer whose theology of creation harmonized with Enlightenment curiosity. Readers of natural history, Romantic literature, and environmental studies will find this classic both foundational and unexpectedly contemporary: a masterclass in noticing. For anyone seeking rigorous, humane observation and the pleasures of place-based inquiry, Selborne remains an indispensable companion in an age of ecological uncertainty.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.
