Kosmos 954 and Operation Morning Light: The History of Efforts to Contain Radioactive Debris Spread Across Canada by a Soviet Satellite examines how the satellite malfunctioned, the disastrous results, and efforts to clean up the radioactivity.

At the start of the 1840s, the Oregon Country had no political boundaries or effective government. The only administrative organization in the territory was the Hudson’s Bay Company, which applied only to British subjects, and aside from natives, the region was populated by a handful of independent traders, hunters, and prospectors, as well as those employed in the various company depots.

All Americans are familiar with the “day that will live in infamy”. At 9:30 a.m. on Sunday, December 7, 1941, Pearl Harbor, the advanced base of the US Navy’s Pacific Fleet, was ablaze. It had been smashed by aircraft launched by the carriers of the Imperial Japanese Navy. All eight battleships had been sunk or badly damaged, 350 aircraft had been knocked out, and over 2,000 Americans lay dead. Indelible images of the USS Arizona exploding and the USS Oklahoma capsizing and floating upside down have been ingrained in the American conscience ever since.

Men from more than two dozen tribal peoples actively participated in the Civil War by fighting for one side or the other. Recent estimates are that more than 28,000 Indians served as Civil War soldiers. Native Americans in the Civil War: The History and Legacy of Various Indian Tribes’ Participation in the War Between the States explains the various roles played by Native Americans in America’s deadliest war.

Americans have long been fascinated by the Civil War, marveling at the size of the battles, the leadership of the generals, and the courage of the soldiers. The North managed to have spectacular success jointly coordinating operations between the Army and Navy, thanks in large measure to the leadership of officers like David Farragut. While generals like Ulysses S. Grant and William Tecumseh Sherman received the lion’s share of the credit for Union victories, naval forces were instrumental, and Farragut was immediately recognized for his service.

Americans have long been fascinated by the Civil War, marveling at the size of the battles, the leadership of the generals, and the courage of the soldiers. The battles have been subjected to endless debate among historians and the generals themselves. David Farragut and David Dixon Porter: The Lives and Careers of the Adoptive Brothers Who Became the U.S. Navy’s First Admirals chronicles their backgrounds, and how they gained the experiences that proved so critical for the Civil War. You will learn about Farragut and Porter like never before.

Given the passage of time, people tend to debate how good Ruth would be today, including most recently a current MLB reliver, Adam Ottavino, who claimed he would strike out Ruth every time. That claim became even more controversial when Ottavino joined none other than the Yankees ahead of the 2019 season, which led to the reliever walking back some of the comments. But even as far back as 1929, Bucky Harris may have foreseen debates of this kind by pointing out, “These other home run hitters are neck and neck. When the Babe was doing his stuff, he was miles ahead of his field."

Gilgamesh, Hercules, Aeneas, and Lancelot are instantly recognized as mythological heroes in the West, evoking visions of Persian monsters, ghastly labors, and the founding and glorification of cities, but the name Quetzalcoatl is as mysterious as its spelling. Even those who have come across his name when learning about the history of Mesoamerica - particularly the Aztec and the god’s role in the Spanish conquest of their empire - are often unaware that the Mesoamerican deity has tales that equal any of those in the repertoire of the mythological figures mentioned above.

Gunsmiths in early 19th-century America were helped along by noted artisans from Germany, Switzerland, and other European powers, but despite advances made in the European and American musket, the requirement of an exterior spark and percussion to ignite powder for a single-shot discharge remained the paradigm. Similarly, the era was unable to move past the cumbersome weapon that required at least half a minute to reload. The military compensation for such an ungainly and vulnerable process was the alternation of troop lines, in which one fired while the other reloaded from behind.

The Vietnam War could have been called a comedy of errors if the consequences weren’t so deadly and tragic. In 1951, while war was raging in Korea, the United States began signing defense pacts with nations in the Pacific, intending to create alliances that would contain the spread of Communism. As the Korean War was winding down, America joined the Southeast Asia Treaty Organization, pledging to defend several nations in the region from Communist aggression. One of those nations was South Vietnam.

Given his legacy, many Americans today believe Jackie Robinson was the first black man to play in Major League Baseball, but that answer is wrong. As far back as the late 19th century, there had been professional baseball leagues that were every bit as segregated as any other aspect of society, but before that, there were, for a brief shining moment, there were teams of black and white men playing with and against each other.

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 it might be hard to believe, the Americans did not have a covert operations organization when they joined the war, and like the British, it took them some time to realize it could be a powerful tool. As a result, the Office of Strategic Services (OSS) was not established until June 13, 1942, six months after the attack on Pearl Harbor. And of course, it would all chart a path for the early days of America’s most famous intelligence agency, the CIA.

A trip to Havana, Cuba, otherwise known as the “City of Columns”, tops many bucket lists for good reason. The mere mention of this once-hidden gem of a city, situated on the western part of the largest Caribbean island nation, evokes the breathtaking imagery of sun-soaked streets and sprawling, golden-sand beaches surrounded by twinkling, almost impossibly crystalline waters, reminiscent of pastel sapphires.

The Wright Brothers initially underestimated the difficulties involved in flying, and they were apparently surprised by the fact that so many others were working on solving the “problem of human flight” already. Decades before their own historic plane would end up in the National Air & Space Museum, Wilbur and Orville asked the Smithsonian for reading materials and brushed up on everything from the works of their contemporaries to Leonardo Da Vinci.

Few people need to be reminded in the 21st century of the cost of European imperialism and colonization on indigenous and native cultures around the world. The increasingly controversial view of Columbus Day, still represented on the United States commemorative calendar, attests quite clearly to an ambiguous modern view of early European encounters with Native Americans. Slavery, disease, land and resource appropriation, and the rapid disintegration of indigenous societies are all characteristics of European global expansion.

The Soviet Nuclear Weapons Program: The History and Legacy of the USSR’s Efforts to Build the Atomic Bomb examines the Soviets’ race to reach the ultimate goal during and after World War II, and how they went about their objectives. You will learn about Nazi Germany’s nuclear weapons program like never before.

Dirigibles proved popular in a variety of different ways throughout the 20th century, and they continued to be complements, even as airplane technologies rapidly advanced. Modern Balloons and Airships: The History and Legacy of Dirigibles During the 20th Century looks at the development of balloons and airships during the 20th century and the innovative ways they were used.
