Novedades del último mes en ebooks de ciencias

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 ultimo tomo se reunen los libros X-XIII, que tratan la inconmensurabilidad, las rectas irracionales y la geometria de los cuerpos solidos.

When astronauts reach orbit and look back at the Earth, they frequently experience a profound and permanent psychological shift. This phenomenon, known as the Overview Effect, instantly dissolves national borders, political ideologies, and earthly anxieties. The human mind is suddenly forced to comprehend the fragility of a glowing blue sphere suspended in an infinite void.This reaction is not merely poetic; it is a violent cognitive restructuring. For our entire evolutionary history, the human brain has been calibrated to understand the world from a grounded, horizontal perspective. Being thrust into an omniscient vantage point overloads the brains spatial and philosophical frameworks. Astronauts return to Earth with rewired priorities, struggling to communicate a state of planetary awareness that the terrestrial mind is literally unequipped to grasp."Orbital Epiphany" dives into the psychological ramifications of leaving the planet. It analyzes the specific training protocols designed to handle this cognitive overload and questions how the commercialization of space travel will alter global consciousness.Step outside the horizontal limits of human perspective. Understand the profound fragility of our planetary ecosystem, and discover how a single change in vantage point can permanently rewrite your entire belief system.

When we bite into a potato chip, we believe we are evaluating its quality based on taste and texture. However, the food industry knows that the most critical metric for perceived freshness is hidden in the auditory cortex. The sensation of crunchiness is not just a physical force; it is a meticulously engineered acoustic event designed to trigger a primal neurological reward.Food scientists utilize specialized microphones and pressure sensors to calibrate the exact decibel level and frequency pitch of a breaking chip. If the snap is too quiet or the frequency too low, the brain immediately registers the food as stale and unappetizing, regardless of its actual chemical composition. By optimizing the sonic amplitude of our food, corporations hijack our evolutionary association between loud, crisp sounds and nutrient-dense, fresh vegetables."Acoustic Appetites" uncovers the bizarre intersection of psychoacoustics and culinary chemistry. It reveals how multi-national snack conglomerates manipulate the physics of sound to maximize cravings, bypass our satiety mechanisms, and enforce habitual consumption.Listen closely to the hidden engineering on your plate. Recognize the auditory manipulation governing your dietary choices, and reclaim your autonomy from the highly calculated sonic architecture of modern junk food.

Our brain is divided into two distinct hemispheres, each with its own specialized processing capabilities. The left side handles logic and language, while the right side interprets spatial relationships and emotion. The only reason we do not experience reality as two completely different people is a thick, fibrous bundle of two hundred million nerve fibers known as the corpus callosum.This vital neurological bridge acts as a high-speed data cable, synchronizing our thoughts in milliseconds. When this connection is surgically severedoften to prevent severe epileptic seizuresthe results are terrifying and profound. Patients exhibit "split-brain" syndrome, where one hand might attempt to button a shirt while the other actively tries to unbutton it. The two hemispheres become completely isolated, trapped in a single skull, proving that our sense of a unified "self" is a fragile biological illusion."Split Decisions" explores the fascinating mechanics of this central neural highway. By examining extreme medical cases, the narrative reveals the deeply fragmented nature of human consciousness and how the brain seamlessly covers up its own internal divisions.Understand the biological architecture of your own identity. Learn how heavily you rely on this invisible neurological bridge, and discover the shocking truth about how your brain constructs a single reality.
