World History Philosophy

Kristie Macrakis combines a storyteller's sense of drama with a historian's respect for evidence in this pause-resisting history of intrigue and espionage, love and war, magic and secrecy. From the piazzas of ancient Rome to the spy capitals of the Cold War, Macrakis' global history reveals the drama and importance of invisible ink. From Ovid's advice to use milk for illicit love notes, to al-Qaeda's hidden instructions in pornographic movies, this book presents stories of secret messaging that chart its evolution in sophistication and its impact on history.

Vitamin C begins with scurvy, which afflicted Europe for four hundred years and killed millions. The reasons that a disease whose cure was known from the outset persisted over that time are at once baffling and familiar, and these trials eventually lead to invention of the science of epidemiology. Author Stephen M. Sagar MD then chronicles the discovery of vitamins at the beginning of the twentieth century, a story that encapsulates the rise of a scientific approach to nutrition but with surprising twists and turns.

Civilization and Its Enemies is an extraordinary tour de force by America's reigning philosopher of 9/11, Lee Harris. In it, Harris focuses on the next great conflict: the war between the civilized world and the international terrorists who wish to destroy it.

The Pleistocene spans a period from around 2.5 million years ago (mya) to just over 12,000 years ago, and it was an epoch of enormous change on Earth, mainly characterized by climate changes involving fluctuations between periods of extreme heat and long periods of glaciation. This period is commonly known as the Ice Age, despite the fact there were actually a number of separate periods of cold. The Pleistocene Era: The History of the Ice Age and the Dawn of Modern Humans looks at the development of the era, what life on Earth was like, and the origins of archaic humans.

This audiobook will trace Western civilization back to its roots. In this epic quest, we head all the way back to Greece when Greek philosophers like Socrates and Plato pondered the very meaning of life. Explore the depths of knowledge that were probed by Greek schools of thought, such as the Stoics and the Cynics.

On August 10, 1632, five men in flowing black robes convened in a somber Roman palazzo to pass judgment on a deceptively simple proposition: that a continuous line is composed of distinct and infinitely tiny parts. With the stroke of a pen the Jesuit fathers banned the doctrine of infinitesimals, announcing that it could never be taught or even mentioned. The concept was deemed dangerous and subversive, a threat to the belief that the world was an orderly place, governed by a strict and unchanging set of rules.

This work covers Darwin's part in the second survey expedition of the ship HMS Beagle. It is both a travel memoir and a scientific field journal of anthropological, biological, and geological interest. Darwin conveys his fascination with the natural world in an engaging writing style.

This riveting audiobook takes the listener around the globe and through the centuries to discover how different cultures have sought to combat and treat physical pain. With colorful stories and sometimes frightening anecdotes, Dr. Thomas Dormandy describes a checkered progression of breakthroughs, haphazard experiments, ignorant attitudes, and surprising developments in human efforts to control pain.

An unbelievable series of events led to the establishment of the Northwest Electro-development Laboratory, later the U.S. Bureau of Mines Albany Research Center. Though the fledgling lab had difficulty securing staff due to World War II, world-renown metallurgist William J. Kroll was hired early on as a consultant after fleeing Nazi occupation. Kroll, who had pioneered a method for producing commercial titanium, worked with his core group of associates to develop malleable zirconium, just as a need arose for the little-known metal.

Tim Koeth peered into the crumpled brown paper bag; inside was a surprisingly heavy black metal cube. He recognized the mysterious object instantly—he had one just like it sitting on his desk at home. It was uranium metal, taken from the nuclear reactor that Nazi scientists had tried—and failed—to build at the end of World War II. This unexpected gift, wrapped in a piece of paper inscribed with a few cryptic but crucial lines, would launch Koeth, a nuclear physicist and professor, and his colleague Miriam Hiebert, a cultural heritage scientist, on an odyssey to trace the tale of these cubes.

Esta "Breve historia del mundo" no es un manual al uso: es una epístola-diálogo en un tono llano y accesible, sin los formalismos y las rigideces de los textos académicos, pero también sin el barniz de aparente pedagogía que da una voz de falsete a tantos audiolibros infantiles y juveniles. La perspectiva y el género elegidos por Gombrich convierten su libro en el antecesor moderno de otros tratados, como "El mundo de Sofía" de Jostein Gaarder o "Ética para Amador" de Fernando Savater.

Eine epische Geschichte der großen Zeit der Physik und ihrer leuchtenden Gestalten. Sie waren intellektuelle Abenteurer, Dandys oder Nerds, die tiefe Freundschaften und erbitterte Feindschaften miteinander verbanden. Die bedeutendsten Physiker und Physikerinnen des 20. Jahrhunderts haben einen ungeahnten wissenschaftlichen Schub ausgelöst, der zu einem neuen Weltbild der Physik führte, welches sich uns bis heute nicht vollständig erschließt. Doch das Zeitalter der Relativitätstheorie und der Quantenmechanik war auch das Zeitalter von Kriegen und Revolutionen.

The wonders of the universe never seemed so close. Who named the planets? Why isn't Pluto a planet? And what's the future of space? From ancient cave paintings to flying drones on Mars, humanity's relationship with the skies has changed dramatically. Gazing at the Night Sky looks back at over 5,000 years of history, from ancient Mesopotamian astronomers to the next horizons in space travel.

The sublime evokes our awe, our terror, and our wonder. Applied first in ancient Greece to the heights of literary expression, in the 18th century the sublime was extended to nature and to the sciences, enterprises that viewed the natural world as a manifestation of God's goodness, power, and wisdom. In The Scientific Sublime, Alan Gross reveals the modern-day sublime in popular science. He tells how the great popular scientists of our time evoke the sublime in response to fundamental questions: How did the universe begin? How did life? How did language?

In her graceful, compelling style, Dava Sobel chronicles the history of the Copernican Revolution, relating the story of astronomy from Aristotle to the Middle Ages. In its midst will be her play, And the Sun Stood Still, imagining the dialogue that would have transpired between Rheticus and Copernicus in their months together. As she achieved with her bestsellers Longitude and Galileo's Daughter, Sobel expands the bounds of science writing, giving us an unforgettable portrait of scientific achievement.

A squared plus b squared equals c squared. It sounds simple, doesn’t it? Yet this familiar expression opens a gateway into the riotous garden of mathematics, and sends us on a journey of exploration in the company of two inspired guides, Robert and Ellen Kaplan. With wit, verve, and clarity, they trace the life of the Pythagorean theorem, from ancient Babylon to the present, visiting along the way Leonardo da Vinci, Albert Einstein, President James Garfield, and the Freemasons - not to mention the elusive Pythagoras himself.

In a world rife with willful chaos, how can order be restored? Philosopher Thomas Hobbes’s answer, composed amid the violence of the English Civil War, revolutionized political thought. His solution was a commonwealth, or Leviathan, a body politic ruled and protected by an absolute sovereign. Its power would be dependent on the people to exchange their freedom for the security and order of a common law. Only with this social contract, Hobbes argued, can civil peace be established.

How did the ancient Egyptians travel in this quaint old land thousands of years ago? What sort of transportation did they use? For how long did they go? What destinations did they visit? For which purposes did they travel? Is it correct to describe the ancient Egyptian travels as "tourism" or not? According to our current perceptions of tourism, if the Egyptians had tourism in ancient times, did they understand it as such? Which varieties of tourism did the ancient Egyptians have compared to what mankind has today?

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.

Air pollution prematurely kills seven million people every year, including more than one hundred thousand Americans. It is strongly linked to strokes, heart attacks, many kinds of cancer, dementia, and premature birth, among other ailments. In Choked, Beth Gardiner travels the world to tell the story of this modern-day plague, taking listeners from the halls of power in Washington and the diesel-fogged London streets she walks with her daughter to Poland’s coal heartland and India’s gasping capital.
