Showing results for "Dark" in History & Philosophy

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

Throughout history, people have sought to reduce suffering, eliminate disease and enhance desirable qualities in their children. In the Victorian era eugenics, a full-blooded attempt to impose control over unruly biology, began to grow among the powerful and quickly spread to dozens of countries around the world. But these ideas are not merely historical: today, with new gene editing techniques, conversations are happening about tinkering with the DNA of our unborn children to make them smarter, fitter, stronger.

In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times best-selling author of Warped Passages and Knocking on Heaven's Door uses her research into dark matter to illuminate the startling connections between the farthest reaches of space and life here on Earth.

The medieval Catholic Church, widely considered a source of intolerance and inquisitorial fervor, was not anti-science during the Dark Ages - in fact, the pope in the year 1000 was the leading mathematician and astronomer of his day. Called The Scientist Pope, Gerbert of Aurillac rose from peasant beginnings to lead the church. By turns a teacher, traitor, kingmaker, and visionary, Gerbert is the first Christian known to teach math using the nine Arabic numerals and zero.

Instruments of modern physics can measure the energies of the electromagnetic spectrum, but these energies only account for roughly 4 percent of the total identifiable mass-energy of the universe. What makes up the remaining 96%? In this scientifically based yet accessible analysis, Yury Kronn, Ph.D., explores the nature of the remaining 96% of the universe’s mass-energies. Contemporary science calls this mass energy “dark matter,” and the ancients called it life force, prana, or chi.

Our insatiable demand for animals - for jewelry, pets, medicine, meat, trophies, and fur - is driving a worldwide poaching epidemic, threatening the continued existence of countless species. Rachel Nuwer, an award-winning science journalist with a background in ecology, takes listeners on a narrative journey to the front lines of the trade: to killing fields in Africa, traditional medicine black markets in China, and wild meat restaurants in Vietnam. Through exhaustive first-hand reporting that took her to 10 countries, Nuwer explores the forces currently driving the demand.

Sin tener en cuenta la ética ni el bienestar de hombres y mujeres, la historia de la ciencia acumula experimentos transgresores, crueles y con consecuencias irreparables para quienes participaron en ellos. Gabriel León nos presenta investigaciones médicas como las esterilizaciones forzadas, los experimentos dermatológicos en cárceles, la separación al nacer de gemelos idénticos y un largo y horroroso etcétera narrado con la claridad, potencia y los fundamentos que lo han convertido en uno de los autores best sellers de la divulgación científica en Chile.
