In this book, John Dvorak, the acclaimed author of Earthquake Storms, looks into the early years of volcanology and its "father", Thomas Jaggar.

Some events that transform a nation are frozen in time. Others pass with little public awareness and we only appreciate their momentous nature long after they occurred. Regardless, these events are few and - almost always - far between. But 50 years ago, in 1969, four such events took place within the span of only 100 days. In this book, cultural historian Harlan Lebo looks back at the first Moon landing, the Manson family murders, Woodstock, and the birth of the Internet to tell the story of how each event shaped the nation and how we perceive ourselves.

In Tin Cans and Greyhounds, author Clint Johnson brings listeners inside the quarter-inch hulls of destroyers to meet the men who manned the ships' five-inch guns and fought America's wars from inside a "tin can" - risking death by cannon shell, shrapnel, bomb, fire, drowning, exposure, and sharks.

The Civil War was the first "modern war." Because of the rapid changes in American society, Abraham Lincoln became president of a divided United States during a period of technological and social revolution. Among the many modern marvels that gave the North an advantage was the telegraph, which Lincoln used to stay connected to the forces in the field in almost real time. No leader in history had ever possessed such a powerful tool to gain control over a fractious situation. An eager student of technology, Lincoln had to learn to use the power of electronic messages.

From 1953 to 1969, the Supreme Court under Chief Justice Earl Warren brought about many of the proudest achievements of American constitutional law. The Warren Court declared racial segregation and laws forbidding interracial marriage to be unconstitutional; it expanded the right of citizens to criticize public officials; it held school prayer unconstitutional; and it ruled that people accused of a crime must be given a lawyer even if they can't afford one. Yet conservative critics have fiercely accused the justices of the Warren Court of abusing their authority....

Einstein's theory of gravity, as beautiful as it is, seems to be in direct contradiction with another theory he helped create: quantum mechanics. From the explosions of neutron stars and the collisions of black holes to the modern scientific process as a means to seek truth and understanding in the cosmos, this audiobook takes the listener on a journey of learning and discovery that has been 100 years in the making.

Leadership is not about position, it is about influence. You can be a leader no matter what your rank or position. It is not about power, it is about selflessness.

In American Patriots, historian Ralph Young chronicles the key role dissent has played in shaping the United States. Some of these protesters are celebrated heroes of American history, while others are ordinary people, frequently overlooked, whose stories show that change is often accomplished through grassroots activism.

American Patriots contrasts this attack with the history of American protest.
