«Saborea laexperiencia dequeteestalle la cabeza sinnecesidad dealucinógenos».The GuardianEn octubre de 1927, veintinueve de los científicos más brillantes del mundo se reunieron en el Quinto Congreso

Desde la Grecia clásica hasta las investigaciones más punteras, esta es la apasionante historia de uno de los mayores misterios del universo: el vacío.Los descubrimientos más recientes han transformado nuestra comprension del vacio y del universo. A lo largo de la historia, la ciencia y la filosofia lo imaginaron como una nada absoluta, pero hoy sabemos que el vacio es un campo vibrante, pleno de energia y origen de todo lo existente. Con rigor y sensibilidad, Guido Tonelli nos guia por un viaje que une fisica, filosofia y cosmologia para mostrarnos como el vacio, lejos de ser ausencia, es la fuerza que da forma al cosmos y a nuestra propia existencia.

Una serie de encuentros estelares especiales que se entrelazan para contar la historia de las numerosas formas y encarnaciones que adoptan las estrellas. Tanto si quiere conocer el origen de las galaxias como si aspira a entender la complejidad del firmamento nocturno, esta es la guia perfecta no solo para saber que son las estrellas, sino tambien para conocerlas de verdad. Ademas de las estrellas, se incluye la informacion sobre las galaxias en las que residen y el cosmos que iluminan. La humanidad ha observado el final explosivo y devastador de algunas estrellas tanto en tiempos de civilizaciones antiguas como con tecnologias modernas. A traves de las observaciones y los modelos mas avanzados de estos cataclismos, hemos aprendido a interpretar que queda despues de estos estallidos, si es que queda algo; como se formaron los elementos quimicos de este planeta, y cuanto le deben el oro y la plata de la Tierra al final de las estrellas.Hay estrellas que cambian de brillo con el paso del tiempo, algunas a intervalos tan predecibles que hemos logrado utilizarlas como indicadores de distancias dentro de un universo que, gracias a ellas mismas, se nos ha revelado mucho mas grande de lo que creiamos. Las estrellas nos han enseñado que el universo contiene componentes invisibles mucho mas abundantes que los que logramos ver, y su brillo nos ha desvelado como se formaron las galaxias y como han ido cambiando con el paso del tiempo cosmico.

This cosmological work presents a geocentric model of the universe, dividing the cosmos into the sublunary sphere of change and the eternal, unchanging celestial realm. Aristotle argues for the spherical shape of the earth and the circular motion of the heavenly bodies, composed of a unique fifth element called aether. The text explores the nature of weight, movement, and the finite structure of the universe. It represents a comprehensive attempt to map the physical architecture of the heavens and the laws that govern them.

"The Nuclear Scout The teenager who built a nuclear reactor in his shed" recounts the terrifying true story of David Hahn. In the mid-1990s, this Michigan teenager, obsessed with chemistry and earning his Boy Scout merit badge, decided to build a breeder reactor in his mothers potting shed. He didnt have a lab; he had household items.Science writer David Core details how Hahn sourced radioactive materials: americium from smoke detectors, thorium from camping lantern mantles, and radium from antique clocks. He posed as a physics teacher to get advice from government agencies. He actually succeeded in creating a neutron source that irradiated his neighborhood, leading to a massive EPA Superfund cleanup."The Nuclear Scout" is a story of unguided potential. It illustrates the thin line between genius and madness, showing what happens when intelligence and determination are applied without safety, ethics, or adult supervision.

This cosmological study presents a universe composed of concentric spheres, with the earth fixed at the center and the heavens moving in eternal circles. Aristotle differentiates the corruptible matter of the earth from the incorruptible "aether" of the stars, establishing a dual physics for the cosmos. The text argues for the finiteness of the universe and explores the properties of heavy and light bodies. It is a grand attempt to systematize the physical structure of the entire universe based on observation and logical deduction.

"One law to rule the stars, the tides, and the falling apple."In The System of the World, Isaac Newton takes his rigorous mathematical proofs and applies them to the vast canvas of the cosmos. This is the work where the abstract becomes tangible. Newton explains with startling clarity how the same force that pulls an object to the ground keeps the Moon in its orbit and the planets in their dance around the Sun. He demystifies the movement of comets, the bulging of the Earth at its equator, and the rhythmic pulling of the tides. It is a foundational text of the Scientific Revolution, representing the moment humanity finally grasped the invisible threads that hold the physical world together.The Unity of the Heavens and Earth: Before Newton, many believed the laws of Earth and the laws of the Heavens were entirely separate. The System of the World shatters this divide. Newtons "Universal Law of Gravitation" proves that the universe is a unified system, predictable and governed by elegant, unchanging laws.A Blueprint for Modern Astronomy: Newton uses this work to calculate the masses of planets and explain the perturbations in their orbits. His insights into the "Great Comet of 1680" proved that even these seemingly chaotic visitors follow the same elliptical paths as the planets, bringing order to the last frontier of the night sky.Why It Is a Scientific Landmark: The System of the World is more than a physics book; it is the birth of the modern world. It moved humanity away from superstition and toward a universe that could be measured, understood, and explored. It is essential reading for anyone who wants to understand the origins of the mechanical age and the leap in logic that allowed us to eventually reach the stars.Witness the logic of the cosmos.

Com uma narrativa ilustrada magnífica, o astrofísico mais célebre do mundo, Neil deGrasse Tyson, se junta a Lindsey Nyx Walker em Ao infinito e além para explicar o universo inteiro, do sistema solar aos confins do espaço, com autoridade e humor. Neste livro cativante, o renomado astrofisico e autor best-seller Neil deGrasse Tyson se une a produtora senior do StarTalk, Lindsey Nyx Walker, para conduzir os leitores em uma odisseia interestelar, combinando ciencia, humor e algumas cutucadas sutis em Hollywood pela forma como o espaço sideral e retratado nos filmes.A viagem começa nos arredores da Terra e avança ate exoplanetas, nebulosas e galaxias. Quanto mais longe nos aventuramos, mais instigantes as perguntas se tornam, pois e quando a teoria desafia o senso comum: Qual e a forma do universo? O que acontece quando dois buracos negros se fundem? Nasceram outros mundos a partir do Big Bang e podemos visita-los?Ao longo do livro, a ciencia abraça a cultura pop a medida que Tyson e Walker vibram com os genios dos efeitos especiais quando eles acertam e no hesitam em apontar as imprecises quando erram. Da franja de Sandra Bullock em Gravidade ao Gargantua de Interestelar, eles navegam por filmes de sucesso, separando a "ciencia" da "ficço".Para os apaixonados por ciencia e para os curiosos que se encantam com os enigmas que desafiam os astrofisicos, este livro esclarecedor e uma divertida aventura rumo aos recantos mais remotos do cosmos.

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.

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.
