We take time for granted as it passes during every moment of our existence. Other things may change, but time remains constant and predictable. The past, the present, and the future exist within a harmonious, reliable, and never-changing system. Or at least that’s how it seems. It was Albert Einstein who, in 1905, first theorized that time might not be quite as straightforward as that. In one of the most influential papers on physics ever published[1], he proposed something called “time dilatation.”

In 1494, there were five sovereign regional powers in Italy: Milan, Venice, Florence, the Papal States, and Naples. In 1536, only one remained: Venice. These decades of conflict precipitated great anxiety among Western thinkers, and Italians responded to the fragmentation, forevermore, of Latin Christendom, the end of self-governance for Italians, and the beginning of the early modern era in a myriad of ways. They were always heavily influenced by the lived experience of warfare between large Christian armies on the peninsula.

The man known to most of the world as Emperor Hirohito ruled during some of the most tumultuous years in Japanese history. When he came to the throne in 1926, he inherited control of a country which had only recently emerged as a major industrial and world power. Through the aggressive expansion and wars of the 1930s, Hirohito was at the head of one of the world’s foremost powers. Throughout the maelstrom of World War II, he remained in power, a distant and, to most outsiders, inscrutable factor in the rise of the Japanese Empire.

The US Naval Station Argentia, located in Placentia Bay, a sheltered harbor on Newfoundland Island, was the unlikely setting for one of the most pivotal summit meetings of the 20th century. The meeting took place on August 9, 1941. World War II was in its second year, the British had won the Battle of Britain, but were still encircled by German U-boats, and the British fleet was being decimated in the North Atlantic.

In 1977, two spacecraft were launched from Earth to explore the outer Solar System, and incredibly, the now-ancient technology from the 1970s is still working, sending daily reports back to the planet that sent the two robotic envoys on their way, over 40 years ago. Voyager 1 and 2 have done far more than accomplish their original missions. In fact, they are now exploring interstellar space, far beyond the outer planets, in the cold wasteland between the stars.

The Transcontinental Railroad, laid across the United States during the 1860s, remains the very epitome of contradiction. On the one hand, it was a triumph of engineering skills over thousands of miles of rough terrain, but on the other hand, it drained the natural resources in those places nearly dry.

Welcome to the Middle East conflict, a conflict that is technically 63 years old and counting but has its roots in over 2,000 years of history. With so much time and history, the peace process has become laden with unique, politically sensitive concepts, like the right of return, contiguous borders, secure borders, demilitarized zones, and security requirements, with players like the Quartet, Palestinian Authority, Fatah, Hamas, the Arab League, and Israel. Over time, it has become exceedingly difficult for even sophisticated political pundits and followers to keep track of it all.

Over 1,100 years before William the Conqueror became the King of England after the Battle of Hastings, Julius Caesar came, saw, and conquered part of “Britannia”, setting up a Roman province with a puppet king in 54 BCE. In the new province, the Romans eventually constructed a military outpost overlooking a bridge across the River Thames. The new outpost was named Londinium, and it covered just over two dozen acres.

"A long time ago, when all the grandfathers and grandmothers of today were little boys and little girls or very small babies, or perhaps not even born, Pa and Ma and Mary and Laura and Baby Carrie left their little house in the Big Woods of Wisconsin." So begins the first of a series of primarily autobiographical books for children that would give 20th century America a look at what it was like when the country was still young and the West was a largely empty, untamed wilderness.

The United States has one of the most technically sound criminal justice systems in the world. Mostly derived from English common law, the U.S. Constitution explicitly lays out when and how a citizen can be searched and arrested, as well as their other rights to trial. But, as with many of the Constitution’s powers, the experiences of the colonists at the hands of the British shaped our legal system’s criminal procedure laws.

Heinz Wilhelm Guderian was one of the most respected commanders and theoreticians of World War II. An innovative tank commander, he was a pioneer of German Blitzkrieg tactics and therefore a hugely influential figure in the way the war was fought. Guderian's profile was not always what might have been expected for a man of his abilities and influence, due to the shape of his career.

One of the most influential Native American tribes on the Great Plains was the Arapaho, a group so renowned among neighboring Native Americans that it's believed their name came from a Pawnee word for "trader. Like other notable Plains tribes, the Arapaho split off from other groups around the 16th-17th centuries and shifted from a sedentary agricultural society to the kind of nomadic group many envision when thinking of groups on the Plains.

Since the first contact between natives and settlers, tribes like the Sioux, Cherokee, and Navajo have both fascinated and perplexed outsiders with their history, language, and culture. In Charles River Editors' Native American Tribes series, readers can get caught up to speed on the history and culture of North America's most famous native tribes in the time it takes to finish a commute, while learning interesting facts long forgotten or never known.

Start a sentence with "Get your kicks on..." and most Americans will immediately complete the sentence with "Route 66". Route 66 conjures up visions of a fun road trip across the United States, whether it was a bird's eye view from a snappy convertible or from a station wagon hauling a trailer. There was fun to be had around every turn. For thousands, Route 66 was far from fun. Route 66 was the way to a better life.

Moses Ben Maimon, frequently called Maimonides, was a medieval philosopher who revolutionized thinking about ethics, reason, and the Jewish Torah through his emphasis on reason and evidence. His works were broadly accepted by the Sephardi Jewish community and spread across the medieval world. St. Thomas Aquinas is known as one of the most important medieval philosophers and in many respects a harbinger of the Renaissance that began to flourish across Europe in the centuries that followed his life.

Portuguese Macau examines how this tiny foothold managed to last as a European possession for so long, and the dynamics that led to China establishing sovereignty over it at the end of the 20th century.

Of all the things that a nation, or even an individual, need to survive a crisis, none is perhaps as necessary as hope. That feeling that somehow one can survive, win even, though the odds are stacked against them and the outlook is grim. Throughout its history, the United States has been blessed, often when most needed, with hope from a strange place.

Today the Space Race is widely viewed poignantly and fondly as a race to the Moon that culminated with Apollo 11 “winning” the Race for the United States. In fact, it encompassed a much broader range of competition between the Soviet Union and the United States that affected everything from military technology to successfully launching satellites that could land on Mars or orbit other planets in the Solar System. The notion that America “won” the Space Race at the end of the 1960s overlooks just how competitive the Space Race actually was in launching people into orbit.

Though scarcely mentioned in the world of early 21st century politics, Manchuria represented a key region of Asia during the first half of the 20th century. Once the heartland of the fierce Manchu empire, this northeastern Chinese region's rich natural resources made it a prize for nations in the process of entering the modern age, and three ambitious nations in the midst of such a transformation lay close enough to Manchuria to attempt to claim it: Japan, Russia, and China.

Over the course of its history, England has engaged in an uncountable number of battles, but none of her military heroes has had a greater military legacy than Admiral Lord Horatio Nelson, 1st Viscount Nelson, 1st Duke of Bronté. Whether traveling to Trafalgar Square or one of the hundreds of pubs named after him, seemingly it becomes easy to believe that no Briton has cast as long a shadow.
