Uranium is best known for the destructive power of the atom bombs, which ushered in the nuclear era at the end of World War II, but given the effectiveness of nuclear power, nuclear power plants were constructed around the developed world during the second half of the 20th century. While nuclear power plants were previously not an option and thus opened the door to new, more efficient, and more affordable forms of energy for domestic consumption, the use of nuclear energy understandably unnerved people living during the Cold War and amidst ongoing nuclear detonations.

It takes a special type of person to serve in a nation’s navy, especially on long voyages that separate men and women from their loved ones, and no service is both loved and hated as that aboard submarines, for very few people ever serve on them on a whim. For one thing, the psychological impact of being trapped for long periods underwater in tight, cramped quarters is more than many people can stand.

During the Late Bronze Age, from about 1500-1200 BCE, the Near East was a time and place where great kingdoms and empires vied for land and influence, playing high stakes diplomatic games, trading, and occasionally going to war with each other in the process. The Egyptians, Hittites, Babylonians, Assyrians, and several smaller Canaanite kingdoms were all part of this system, which was one of the first true “global” systems in world history and also one of the most materially prosperous eras in antiquity.

Freedom of the press isn’t just a fundamental right in America but a key part of the democratic process. When the United States secured its independence against Britain in the War of Independence in 1783, there was no certainty about what the new country would look like in terms of national governance. In 1787, delegates from the various states convened in Philadelphia to draft a constitution that would define this.

Of the many campaigns during the Middle Ages, few are as remarkable or seemingly impossible to win at the start as the First Crusade (1095-99), and the true crowning achievement of that crusade, which resulted in two centuries of Western European Christian states in the Middle East and the permanent firing of the European imagination, was the conquest of Jerusalem on July 15, 1099 after three weeks of siege.

Since the early days of human warfare, which may date back to the Stone Age, combatants have sought to gain an advantage through the acquisition of secret information. With the growth of technology, a parallel advantage was sought through the application of numerous types of torture. In the 19th century, the concept of manipulation was added to military tactics, an attempt to influence the minds of assassins, double agents, and world leaders alike to act against their natures.

Nikola Tesla was one of history’s greatest scientists, and though he is best known for his pioneering work with electricity, the fact that he is mostly remembered solely for that actually does a disservice to his legacy.

For nearly a thousand years following its foundation, there was only one Christian Church. Centered in the city of Rome, the Church expanded and grew until it became the dominant religion in Europe and beyond. The early growth of the Church had been suppressed by the Romans until the Emperor Constantine became the first to convert the empire to Christianity, and from that point forward, the growth of the Church was inextricably linked with the Roman Empire, the most powerful military, economic, and political force in the ancient world.

What happens when you put good people in a bad place? That was the question that an experiment in 1971 set out to answer when Stanford University professor and psychologist Philip Zimbardo used funding provided by the U.S. Office of Naval Research to create a make-believe prison in the basement of a university building. Male students were offered the chance to take part in the two-week experiment (and to make $15 per day). All applicants were carefully screened to ensure that they were healthy, emotionally and psychologically stable. 24 men were selected out of 75 that had applied.

Germany's North African defeat opened up the possibility of taking the war in the West to the European continent for the first time since France's lightning conquest by the Wehrmacht in 1940. The British and Americans debated the merits of landing in France directly in 1943, but they ultimately opted against it. The Soviets railed at the Westerners as “bastards of allies”; but a 1943 “D-Day”-style landing in France might have proven a strategic and logistical impossibility.

During the first half of the 1st millennium CE, an empire arose in Persia that extended its power and influence to Mesopotamia in the east, Arabia in the south, the Caucasus Mountains in the north, and as far east as India. This empire, known alternatively as the Sasanian Empire or Sassanid Empire, was the last of three great dynasties in Persia—the Achaemenid and the Parthian being the first two dynasties—before the rise of Islam.

Among all the Native American tribes, the Spanish, Mexicans, and Americans learned the hard way that the warriors of the Apache were among the fiercest in North America. Based in the Southwest, the Apache fought all three in Mexico and the American Southwest, engaging in seasonal raids for so many centuries that the Apache struck fear into the hearts of all their neighbors. Given the group's reputation, it's fitting that they are inextricably associated with one of their most famous leaders, Geronimo.

In their long history of suffering, nothing was ever so terrible as what the Irish endured during the Great Potato Famine that struck the country in the 1840s. It produced massive upheaval for several years. While countless numbers of Irish starved, the famine also compelled many to leave. And all the while, the British were exporting enough food from Ireland on a daily basis to prevent the starvation.

As a basic definition, it may be said that an Ice Age is simply a period of time during which thick ice sheets cover vast areas of land. These sheets have advanced and retreated, at times taking over the entire planet, and conversely disappearing nearly altogether. Glacial ice formed by this regularly occurring process does not sit in a state of inertia, but moves dynamically, reshaping the geological features of the continents.

In World War II, hundreds of thousands of American soldiers were killed across the world, whether in Japanese jungles, North African deserts, or European beaches. Given that backdrop and the sheer magnitude of the war, people understandably became desensitized to incidents and tragedies that cost hundreds of lives. This was undoubtedly the case with the notorious Port Chicago disaster, a munitions explosion in July 1944 that killed over 300 people and injured over 300 more, many of them navy sailors.

Scotland is a fascinating and ancient land filled with history. Not everything in Scotland is as it appears, however. Some Scots say this is a land haunted by spirits, a place of strange disappearances and unexplained phenomena. The Ghosts of Scotland: A Collection of Ghost Stories Across the Scottish Nation is a collection of such tales, just a few among the thousands of local legends and modern sightings that make Scotland one of the most haunted countries in the world.

Theologian and reformer John Wycliffe never had the opportunity to take his doctrines outside of his native England, but he could never have imagined that his teachings would one day travel as far as 920 miles east to Bohemia. One curious mind, however, was supposedly so inspired by Wycliffe that he was at once galvanized into action. Instead of simply parroting Wycliffe's seditious ideas, he launched an entire movement and remained fervidly true to his cause, even when his own life was at stake.

Yuri Bezmenov was among the first Soviet whistleblowers to attract attention on a global scale, and interest in his story has recently been revived thanks to his surprising cameo in the teaser trailer for Call of Duty Black Ops: Cold War in August 2020. This came despite the fact he was far from the first ex-KGB agent or Russian to pull back the curtains on the Russian government and reveal the harrowing “truths” they were once sworn to harbor.

Set in the northeastern corner of Spain and nestled next to France is the autonomous region of Catalonia. More than seeing themselves as Spaniards, Catalonian people see themselves as Catalan first and foremost, and they all are natively fluent in the language, Catalan. After a tumultuous history during which it bounced back and forth in terms of its political status and relationship to Spain’s central government, Catalonia was granted its autonomy on December 18, 1979. In 2006, it came close to acquiring its total independence, but that status is still being hotly contested.

As technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. It would hardly be groundbreaking for scientists in the 20th century to have a lunchtime discussion in which the search for extraterrestrial life arises, and the question of where it might reside is innocuous enough. However, a furor was created somewhat innocently when physicist Enrico Fermi voiced his “casual lunchtime remark” in the presence of colleagues in 1950.
