Centuries ago, Spanish conquistadors searching for gold and new lands encountered a group of independent city-states in Mesoamerica. Sophisticated beyond the Spaniards' wildest imaginings, these people were the Aztecs, the Maya, and related cultures that shared common traditions of religion, government, the arts, engineering, and trade. In many ways more advanced than European nations, these societies equaled the world's greatest civilizations of their time.

The Knights Templar were the wealthiest, most powerful - and most secretive - of the military orders that flourished in the crusading era. Their story - encompassing as it does the greatest international conflict of the Middle Ages, a network of international finance, a swift rise in wealth and influence followed by a bloody and humiliating fall - has left a comet's tail of mystery that continues to fascinate and inspire historians, novelists and conspiracy theorists. Unabridged edition read by Dan Jones.

Touched off by a terrorist act in Bosnia and spreading all too quickly beyond the expectations of those who were involved, World War I was an unprecedented catastrophe with a ghastly cost. After this first "total war"-the first conflict involving entire societies mobilized to wage unrestrained war, devoting all their wealth, industries, institutions, and the lives of their citizens to win victory at any price - the world itself would never be the same.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

The Tao of Seneca (volumes 1-3) is an introduction to Stoic philosophy through the words of Seneca. If you study Seneca, you'll be in good company. He was popular with the educated elite of the Greco-Roman Empire, but Thomas Jefferson also had Seneca on his bedside table. Thought leaders in Silicon Valley tout the benefits of Stoicism, and NFL management, coaches, and players alike - from teams such as the Patriots and Seahawks - have embraced it.

In an exciting partnership with the Smithsonian, The Great Courses presents these 24 lectures that offer an unforgettable tour of Japanese life and culture. Professor Ravina, with the expert collaboration of the Smithsonian's historians, brings you a grand portrait of Japan.

At the dawn of the last millennium in the year 1000, Europe was one of the world's more stagnant regions-an economically undeveloped, intellectually derivative, and geopolitically passive backwater, with illiteracy, starvation, and disease the norm for almost everyone. Yet only three centuries later, all of this had changed.

The science fiction genre has become increasingly influential in mainstream popular culture, evolving into one of the most engaging storytelling tools we use to think about technology and consider the shape of the future. Along the way, it has also become one of the major lenses we use to explore important philosophical questions. The origins of science fiction are most often thought to trace to Mary Shelley's novel Frankenstein, a story born from a night of spooky tale-telling by the fireside that explores scientific, moral, and ethical questions that were of great concern in the 19th century - and that continue to resonate today.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity. He was trying to find an equation that explained all physical reality - a theory of everything. Experimental physicist and award-winning educator Dr. Don Lincoln takes you on this exciting journey in The Theory of Everything: The Quest to Explain All Reality. Suitable for the intellectually curious at all levels and assuming no background beyond basic high-school math, these 24 half-hour lectures cover recent developments at the forefront of particle physics and cosmology.

Look beyond the abstract dates and figures, kings and queens, and battles and wars that make up so many historical accounts. Over the course of 48 richly detailed lectures, Professor Garland covers the breadth and depth of human history from the perspective of the so-called ordinary people, from its earliest beginnings through the Middle Ages.

Alexander was born into the royal family of Macedonia, the kingdom that would soon rule over Greece. Tutored as a boy by Aristotle, Alexander had an inquisitive mind that would serve him well when he faced formidable obstacles during his military campaigns. Shortly after taking command of the army, he launched an invasion of the Persian Empire, and continued his conquests as far south as the deserts of Egypt and as far east as the mountains of present-day Pakistan and the plains of India.

The Blind Watchmaker, knowledgably narrated by author Richard Dawkins, is as prescient and timely a book as ever. The watchmaker belongs to the 18th-century theologian William Paley, who argued that just as a watch is too complicated and functional to have sprung into existence by accident, so too must all living things, with their far greater complexity, be purposefully designed. Charles Darwin's brilliant discovery challenged the creationist arguments; but only Richard Dawkins could have written this elegant riposte.

No Stone Unturned recreates the genesis of NecroSearch International: a small ,eclectic group of scientists and law enforcement personal, active and retired, who volunteer their services to help locate the clandestine graves of murder victims and recover the remains and evidence to assist with the apprehension and conviction of the killers.
