For the Maya, astronomy was not a purely scientific pursuit, but intimately linked to religious, mythological, and ideological elements that were of the highest importance. The celestial realm held a sacred nature, as did the many gods and goddesses that dwelt there, so for all Mesoamerican cultures, astronomy was a fundamental part of their everyday lives. Thus, astronomy was present in their calendars, religion, and even agriculture, and in close relation to astronomy, the concept of time was also an essential part of their worldview.

When most people think of “ancient American civilizations,” the Aztec, Maya, or Inca cultures probably come to mind immediately, because the societies in Mesoamerica have left behind permanent structures for millions of visitors from around the world to see each year. At the same time, however, from about 1000-1500 CE, an equally complex culture formed along the banks of the Mississippi, Missouri, and Ohio Rivers.

Much has been written about Western intervention during the breakup of Yugoslavia, and whether it made matters worse, prevented worse atrocities, or was simply ineffective. In early 1992, however, what was clear was that Europe was hopelessly divided over the best course of action to take towards Yugoslavia, and after several years of fighting, the Bosnian War was one of the most violent conflagrations in Europe since the end of World War II.

Virtually everyone in America is familiar with theories about UFOs, or “flying saucers” as they were often called then, but even this name dates back only to 1947. Before that time, they were called “ghost rockets” or “ghost airplanes” or “ghost airships.” Before the age of flight, the flying objects were called various things such as “flying chariots.” No matter what terminology is used, every generation has clearly had its own belief that mankind is not alone.

People have always been fascinated with the hidden, the mysterious, and the unexplained. Every society has its tall tales and ghost stories, its odd legends, and heroes. Also, every society has its stories of strange beasts, dangerous or benign, that live in the twilight world between the everyday and the legendary.

Naval combat underwent a significant metamorphosis during World War II. Nazi Germany and Imperial Japan launched some of the most powerful battleships ever to sail the world's oceans, yet the conflict witnessed the emergence and triumph of the aircraft carrier as the 20th century's true monarch of the seas.

The early history of Earth covers such vast stretches of time that years, centuries and even millennia become virtually meaningless. The first four billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life in Earth. Then the first single-celled life-forms, early bacteria and algae, began to emerge. We don’t know where they came from or even if they originated on this planet at all.

The social importance placed on food and wine in the Greek world was even more pronounced, with profound consequences for the rest of the world.

The fur trade had its tensions, but for many years, traders and natives worked out their own systems, times, and traditions, allowing many different groups to interact and even compete without issues that led to war. Though native groups sometimes found themselves in conflicts based on long-standing rivalries or relations with the Europeans, most of the fur traders, the trappers, the Indians, and Hudson’s Bay Company officials lived peaceably.

In the wake of taking Constantinople, the Ottoman Empire would spend the next few centuries expanding its size, power, and influence, bumping up against Eastern Europe and becoming one of the world’s most important geopolitical players. It was a rise that would not truly start to wane until the 19th century.

Without question, the most famous battle of the American Civil War took place outside of the small town of Gettysburg, Pennsylvania, which happened to be a transportation hub, serving as the center of a wheel with several roads leading out to other Pennsylvanian towns.

The concept of international trade was born in the ancient Mediterranean, which provided the perfect set of circumstances needed to produce an intricate trading system whose influence can still be seen in present-day economic practices.

The 17th century in Europe, particularly its latter years, is often considered the beginning of the Enlightenment, as nations across the continent experienced a surge in innovation and scientific progress, a period also commonly referred to as the Age of Reason. There was English natural philosopher, Francis Bacon, whose book Novum Organum challenged Aristotelian philosophy and stressed the significance of inductive reasoning.

Rome faced many formidable enemies over the course of nearly 1,000 years, but perhaps none were as enigmatic and forgotten as King Mithridates VI of Pontus. Despite numerous ancient sources detailing the life of the foreign monarch and his wars with Rome, and despite being an interesting character who endured years as a fugitive in his youth, enjoyed a fascination with poisons, and held mercy and pragmatic ruthlessness in a delicate balance, very few scholarly books and works have been produced about the king.

It is something of a cliché to say that an actor’s life was like a movie he or she might have starred in, but in the case of Myrna Loy, the cliché is true. It is easy to picture her as a little girl, riding the range with her rancher father, sitting around the table and participating charmingly in family discussions of current events.

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.

In 1940, the 4th most popular star in the US was a foreign actor from Australia, and unlike other movie stars, he was more notorious for his pursuits off the screen than on it. In an era long before social media, Errol Flynn represented the epitome of a swashbuckling playboy, with enough mystery and intrigue surrounding him and his background to fascinate even those who didn’t see his movies.

Though the importance of hats is easy to overlook, it was deadly serious in more ways than one, impacting the beavers and birds used to make fashionable hats, the environment of the region, and the people fighting over the resources. Beaver hats put the Dutch, British, and French in conflict, and later the Americans and Canadians.

By the time the Hubble telescope reached orbit, it was already the world’s most famous telescope, but it was also the most scorned. The telescope cost nearly two billion dollars more to complete than anticipated, and to make matters worse, the first images it sent back were skewed. However, within about a year of fixing it, the telescope captured images of a major event in the solar system.
