Resultados para "man" en Ciencia e ingeniería

Estamos frente a una revolución como nunca antes había sucedido, un cambio profundo que no solo transforma lo que hacemos sino también lo que somos. Hoy resulta esencial reconocer qué es aquello que nos hace humanos, cuáles son los lazos que nos sostienen como especie y nos alejan de nuestras zonas oscuras, individualistas, menos gregarias.

Hablar de microbiología a los agricultores, y especialmente a los campesinos de bajos recursos, ha sido un tema vedado en la actualidad. Si queremos comprender a fondo las relaciones de nutrientes del suelo con las plantas y los minerales que por acción de los microorganismos se disuelven para ser tomados por las plantas, la microbiología del suelo es un tema fundamental.

When published in 1981, The Mismeasure of Man was immediately hailed as a masterwork, the ringing answer to those who would classify people, rank them according to their supposed genetic gifts and limits. Yet the idea of of biology as destiny dies hard, as witness the attention devoted to The Bell Curve, whose arguments are here so effectively anticipated and thoroughly undermined.

While hiking on a solo vacation in a remote, uninhabitable region of Arizona, Zachary Anderegg happened upon Riley, an emaciated puppy clinging to life, at the bottom of a 350-foot canyon. In a daring act of humanity that trumped the deliberate savagery behind Riley’s presence in such a place, Zak single-handedly orchestrated a rescue. What didn’t come out in the initial burst of publicity this story received is that Zak and Riley’s destinies were intertwined long before they improbably found each other.

En Una científica saltando vallas, Laura M. Lechuga hace un repaso de su carrera, ahondando en los problemas a los que se enfrenta el género femenino en el ámbito científico, tanto académico como profesional, con el propósito de orientar y dar una valiosa lección a las mujeres que desean desarrollar una carrera científica, clave para el progreso científico y técnico de la sociedad.

Getting ready for the Journeyman Electrician Exam can feel overwhelming—so much material, constant NEC code updates, and the pressure of exam day. This audiobook makes the process simple, clear, and achievable.

The Man Who Mastered Gravity is an intimate profile of Thomas Townsend Brown, a little-known scientist whose unorthodox ideas about electricity and gravity have made him the subject of decades of speculation and intrigue. Brown developed his novel concepts while serving in the U.S. Navy through the 1930s. In the first months of World War II he was abruptly discharged–despite his expertise in radio, radar, and mine sweeping.

In How Car Engines Work, you’ll journey step by step through the fascinating science and engineering behind internal combustion. From the spark that ignites the fuel-air mixture to the smooth coordination of pistons, valves, and crankshafts, this guide explains it all—clearly, simply, and with real-world examples that bring each concept to life.

Perhaps the greatest physicist of the second half of the 20th century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits.

Mental health can be a serious health issue, but is often not treated as one because of the social stigma associated with it.

Focusing on the author’s tiger-hunting exploits, Man-Eating Tigers of India includes a detailed description of the tiger’s habits and instructions on how to organize and conduct a safe and successful hunt. This chore of putting an end to man-eating tigers seems to have been the burden of Baker. The work concludes with a riveting narrative of an actual case of hunting and eliminating a troublesome tiger.

In 1929, a 22-year-old maverick named Frank Whittle - a self-taught aeronautical obsessive and risk-takingly brilliant RAF pilot - presented a blueprint for a revolutionary, jet-powered aircraft engine to the Air Ministry. His idea had the potential to change the course of history, but it was summarily rejected. In this meticulously researched biography, Duncan Campbell-Smith charts Whittle's stoic efforts to build his jet engine in the interwar years.

We are all familiar with the "march of progress," the representation of evolution that depicts a series of apelike creatures becoming progressively taller and more erect before finally reaching the upright human form. Its emphasis on linear progress has had a decisive impact on public understanding of evolution, yet the image contradicts modern scientific conceptions of evolution as complex and branching.

Original stories of mountain men between 1833 and 1837 traveling from the Missouri River, through the plains and Rocky Mountains, to the Pacific and back, with all the different Indians and Indian wars they observed from the opposite point of view - from Indians themselves, like Zitkala-Sa, in American Indian Stories and Old Indian Legends.

C. S. Lewis is best known for his Narnia tales and Christian apologetics, works that have sold more than 100 million copies. But Lewis was also a trained philosopher and a professor at Cambridge and Oxford. An intellectual giant, he fiercely and extensively critiqued the fashionable dogma known as scientism - the idea that science is the only path to knowledge, and matter the fundamental reality.

To live in a pristine land unchanged by man... to roam a wilderness through which few other humans have passed... to choose an idyllic site, cut trees and build a log cabin... to be a self-sufficient craftsman, making what is needed from materials available... to be not at odds with the world but content with one's own thoughts and company. Thousands have had such dreams, but Richard Proenneke lived them.

The first operational military jet in the world, toward the end of the Second World War, the Me 262 was to be the German "miracle weapon". Mano Ziegler was involved from its inception and contributed to the design, testing, training, and even served in it operationally. Could the Me 262 have broken the Allied supremacy in the air? Hitler's Jet Plane fills an important gap in the history of the Luftwaffe and of aviation in general with new research which discloses how the first military jet plane failed to make its mark on World War II.

By the end of World War I, Albert Einstein had become the face of the new science of theoretical physics and had made some powerful enemies. One of those enemies, Nobel Prize winner Philipp Lenard, spent a career trying to discredit him. Their story of conflict, pitting Germany's most widely celebrated Jew against the Nazi scientist who was to become Hitler's chief advisor on physics, had an impact far exceeding what the scientific community felt at the time.

To solve one of the great mathematical problems of his day, Alan Turing proposed an imaginary computer. Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide.

Before there was Steve Jobs, there was Norman Bel Geddes. A ninth-grade dropout who found himself at the center of the worlds of industry, advertising, theater, and even gaming, Bel Geddes designed everything from the first all-weather stadium to Manhattan's most exclusive nightclub to Futurama, the prescient 1939 exhibit that envisioned how America would look in the not-too-distant 1960s.
