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. Este segundo tomo incluye los libros V-IX, en los cuales se trata la teoria generalizada de la proporporcion y la teoria aritmetica.

La historia del conocimiento humano está repleta de nombres, acontecimientos e ideas increíbles, y nunca más cierto cuando hablamos de una de las disciplinas que más han revolucionado el mundo científico en los ultimos siglos: la biologia. Consuelo Cuevas da cuenta de las disputas que esta ciencia suscito en Mexico, tanto en los laboratorios como en las aulas, las principales figuras que intervinieron en su desarrollo, sus centros de investigacion en el pais y muchas de las grandes aportaciones que la biologia ha hecho al pueblo mexicano desde la epoca del Porfiriato hasta finales del siglo xx.

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.

Leyendo a Euclides fue escrito en 1947 con el objetivo de atraer la atención de lectores no matemáticos hacia el estudio de conceptos fundamentales de la geometría y la filosofía. Tras analizar el pensamiento socratico y deducir interesantes conclusiones de tipo filosofico, Levi introduce al lector en el analisis exhaustivo de los inmortales Elementos. La presente edicion incluye el ensayo biografico "Beppo Levi, Italia y Argentina en la vida de un matematico", de Laura Levi, hija de Beppo."La logica de la geometria de Euclides, en particular su sistematicidad y coherencia, sigue suscitando admiracion. No debiera extrañar entonces que un matematico moderno como Beppo Levi le haya dedicado un estudio profundo, aunque sin la pesada carga erudita habitual. Ni es de extrañar que, a su vez, este libro del matematico italoargentino despierte la curiosidad de lectores contemporaneos. ¿Que resulto del encuentro de Euclides con Levi a la vuelta de veintidos siglos? Lo averiguaran quienes lean este libro tan original como claro. Aprenderan a ver a Euclides, e incluso a su posible maestro, Platon, con ojos modernos. Y aprenderan, si no lo saben ya, los deleites de la conversacion con muertos sin recurrir a trucos espiritistas". Del prologo de Mario Bunge

Cerrad los ojos. Imaginad un espacio sin límites. Imaginad los movimientos de una partida de ajedrez perfecta. Imaginad que el número 4 pudiera decirse de muchas maneras diferentes. Imaginad los acontecimientos infinitesimales que pueden conducir a que estalle la revolucion en un pais. Imaginad una tribu que, por no saber contar, no planea nada que se prolongue mas de un dia. Imaginad a Shakespeare descubriendo el numero cero y las dimensiones de una ausencia. Imaginad que pudierais leer un libro de una infinidad de maneras distintas.Me llamo Daniel Tammet, y soy sinestesico: percibo los numeros con colores y siluetas. En mi cabeza, contar es como pasear por un bosque. Tengo diagnosticado, ademas, el sindrome del sabio: puedo aprender un idioma en una semana, y recitar decimales del numero pi durante cinco horas (por eso me dieron un Guinness). De pequeño resolvi que, si conseguia reunir suficientes recuerdos y someterlos a un patron estadistico, podria predecir el comportamiento de mi madre. Los numeros primos poseen para mi la belleza de la poesia. No entendi lo que me sucedia hasta que conoci a Rain Man (al de verdad). Cada mañana me siento en mi escritorio y me pregunto: ¿y si...?

It is a masterful example of how education can be seamlessly integrated with entertainment and play.

On average, a human being blinks between 15 and 20 times a minute. While we assume this rapid closure of the eyelids is merely a mechanical reflex to lubricate the cornea and clear away dust, the math doesnt add up; we blink far more frequently than physiology requires.Neuroscientists have uncovered a profound hidden function: the blink is a cognitive punctuation mark. Rather than blinking randomly, our brains subconsciously time our blinks to occur at the precise end of sentences while reading, or during the cut-away of a film scene. During those split milliseconds of darkness, the brains default mode network briefly activates, allowing the mind to dump working memory and refocus attention.This book explores the fascinating neurological machinery behind this involuntary reflex. You will discover how the timing of blinks reveals hidden fatigue, why psychopaths blink less frequently, and how magicians and filmmakers expertly manipulate your blink rate to hide their illusions in plain sight.Realize the power of the dark spaces between your vision. By understanding the neuroscience of the blink, you will uncover how your brain constantly edits reality to keep you focused.

We are taught that the human senses are outward-facing tools: sight, sound, touch, taste, and smell exist to navigate the external world. However, there is a hidden internal sense that dictates our emotional states and decision-making processes far more profoundly than our eyes or ears. It is called interoception.Interoception is your brains continuous, subconscious perception of your internal organsthe subtle shift in your heart rate, the microscopic tension in your gut, or the shallowing of your breath. Long before your conscious, logical brain can process a complex threat or an opportunity, your interoceptive network generates "somatic markers." These are physical sensations that guide your intuition. When you say you have a "gut feeling" about a bad investment, it is not a metaphor; it is your vagus nerve aggressively signaling danger based on pattern recognition faster than conscious thought.This book breaks down the biology of intuition. You will discover why people with poor interoceptive awareness struggle with debilitating indecision, how chronic anxiety is often a misinterpretation of normal internal signals, and how you can actively train your brain to "listen" to your bodys precognitive warnings.Stop treating your body merely as a vehicle for your brain. Learn to read your internal telemetry and harness the rapid-fire intelligence of your somatic markers.

O livro busca dar suporte ao trabalho do professor que ensina matemática para os anos iniciais. Trazendo experiências em que as representações concretas das quatro operações fundamentais são tratadas

You see someone yawn. Within seconds, your jaw stretches, your eyes water, and you are forced to do the exact same thing. Contagious yawning is one of the most universal and uncontrollable human behaviors, yet for centuries, medical science dismissed it as a simple reflex for oxygen intake. Today, neurologists recognize it as a profound window into the evolution of human empathy.Studies show that contagious yawning is deeply linked to the brains mirror neuron systemthe same network responsible for our ability to feel compassion and understand the emotions of others. Psychopaths and those with severe antisocial disorders are notably immune to it. Furthermore, the yawn acts as an evolutionary thermoregulator, cooling the brain to maintain peak alertness within a social group during times of shared fatigue.This fascinating exploration blends evolutionary biology and modern neuroscience to decode the hidden language of the body. It reveals how an involuntary physical spasm serves as an invisible thread binding our social groups together, proving that our capacity to connect with one another is hardwired into our most primal reflexes.

For over a century, the neuron has been the undisputed star of neuroscience. Every textbook taught that these electrical wires were solely responsible for our thoughts, memories, and consciousness. Meanwhile, glial cellswhich make up more than half of the human brainwere dismissed as mere "glue" (the literal translation of glia), serving only as passive support structures for the much more important neurons.Recent breakthroughs in cellular biology have shattered this dogma. We now know that glial cells, particularly astrocytes, are the active architects of our cognitive network. They do not just support neurons; they direct them. Glial cells decide which synaptic connections are strengthened during learning, which are pruned away, and how the brain repairs itself after physical trauma. They are the chemical conductors of the electrical symphony of the mind.This groundbreaking book journeys into the forgotten half of the human brain. It explores how shifting our focus from neurons to the glial network is revolutionizing our understanding of memory, learning, and neurological diseases like Alzheimers, proving that the brains true genius lies in its quietest cells.

Look at a map of global conflict zones, critical mineral deposits, and primary shipping routes. What seems like modern political strategy is actually a script written hundreds of millions of years ago. The wealth of modern nations was predetermined by the violent tearing apart of the ancient supercontinent known as Gondwana.Fractured Earth bridges the massive gap between prehistoric geology and modern geopolitics. The book explains how the specific ways tectonic plates ripped apart left massive, uneven deposits of oil, lithium, copper, and rare earth metals. These geological lotteries created the foundation for 21st-century economic dominance and supply chain vulnerabilities.Through deep geological history, you will understand why certain South American and African coastlines are mirror images rich in identical resources, and how the ancient collisions that formed the Himalayas are directly linked to todays semiconductor manufacturing constraints.Uncover the ultimate root cause of global wealth disparity. By understanding the deep mechanics of continental drift, you will never look at a world map, a geopolitical crisis, or the battery in your smartphone the same way again.

When we look at a globe, we see seven distinct landmasses. But geography holds a massive, hidden secret. Just beneath the turbulent waves of the Pacific Ocean, surrounding the islands of New Zealand and New Caledonia, lies an enormous, fully recognized eighth continent, 94 percent of which is completely submerged.Submerged Zealandia tells the thrilling scientific detective story of how geologists spent decades proving the existence of a landmass half the size of Australia. This wasnt a mythological Atlantis, but a massive chunk of continental crust that violently broke away from the supercontinent Gondwana and slowly sank beneath the sea over millions of years.The book details the extreme challenges of deep-sea bathymetry and satellite gravity mapping required to chart this invisible world. It uncovers what Zealandias fossilized drowned valleys and submerged mountain ranges tell us about the earths violent tectonic history and the ancient flora and fauna that once thrived there.Expand your understanding of the planet you live on. This geological expedition proves that the map of the world is far from finished, and that entire continents can still be hiding right beneath our feet.

Society frequently frames crying as a loss of emotional control, a sign of weakness, or a useless biological reflex. We are taught to hold our tears back, apologizing when they spill over, completely misunderstanding the brilliant biochemical mechanism occurring in our bodies.Science reveals that not all tears are created equal. While basal tears lubricate the eye and reflex tears flush out dust, emotional tears contain a radically different chemical composition. When we cry from grief or joy, our bodies physically excrete massive amounts of stress hormones and natural painkillers, literally weeping away physiological anxiety.The Chemical Release explores the unique evolutionary biology of human crying. It explains how shedding tears is not a breakdown, but rather a highly sophisticated somatic healing process designed to rapidly down-regulate the nervous system and trigger deep social bonding among humans.Change the way you view your own emotions. Learn how suppressing tears actively harms your physical health, and discover why embracing this powerful biological release valve is the key to restoring internal balance and overcoming intense psychological stress.

Close your eyes and touch your nose. You can do it because of proprioceptionthe bodys internal sense of position. But at age 19, Ian Waterman lost this sense completely due to a rare viral infection. He became a "rag doll," unable to stand, sit, or even hold a cup, despite having healthy muscles. He had lost his body.In the tradition of Oliver Sacks, this book tells the inspiring story of how Ian taught himself to move again by using his eyes to replace his nerves. He has to consciously watch every limb to move it. It is a profound exploration of the "sixth sense" that grounds us in reality, and what happens when the connection between mind and flesh is severed.

On August 21, 1986, the farmers around Lake Nyos in Cameroon went to sleep in a silent valley. By morning, every living thing1,746 people, 3,500 livestock, even the flieswas dead. There was no fire, no flood, and no violence. The killer was the lake itself.This book investigates the terrifying phenomenon of a limnic eruption, where a lake "burps" a massive cloud of carbon dioxide, displacing oxygen and drowning a valley in invisible gas. It follows the scientific detective story to understand the event, the race to degas the lake before it strikes again, and the geological ticking time bombs hiding in crater lakes around the world. A gripping look at how the earth breathes, and sometimes, holds its breath too long.

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.
