Sometimes our understanding of our universe is given a huge boost by one insightful thinker. Such a boost came in the first half of the 20th century, when an obscure Belgian priest put his mind to deciphering the nature of the cosmos. The Day Without Yesterday covers the modern history of an evolving universe, and how Georges Lemaître convinced a generation of thinkers to embrace the notion of cosmic expansion and the theory that this expansion could be traced backward to the cosmic origins, a starting point for space and time that Lemaître called "the day without yesterday".

The foundations of modern knowledge - philosophy, math, astronomy, geography - were laid by the Greeks, whose ideas were written on scrolls and stored in libraries across the Mediterranean and beyond. But as the vast Roman Empire disintegrated, so did appreciation of these precious texts. Christianity cast a shadow over so-called pagan thought, books were burned, and the library of Alexandria, the greatest repository of classical knowledge, was destroyed. Yet some texts did survive and The Map of Knowledge explores the role played by seven cities around the Mediterranean....

The sheer importance of Sumerian culture in regards to world culture as a whole is impossible to overstate. This civilization is single-handedly responsible for some of the most major innovations in nearly every field relevant to maintaining a civilized society - this includes religion, lawmaking, architecture, schooling, art, literature, and even entertainment. Naturally, most of what we see as negative aspects of society were established in ancient Sumer as well. There wasn’t an aspect of Sumerian life that wasn’t plagued with corruption or devastation of one form or another.

The Vikings maintain their grip on our imagination, but their image is too often distorted by medieval and modern myth. It is true that they pillaged, looted, and enslaved. But they also settled peacefully and developed a vast trading network. They traveled far from their homelands in swift and sturdy ships, not only to raid, but also to explore. Despite their fearsome reputation, the Vikings didn’t wear horned helmets, and even the infamous berserkers were far from invincible.

Why didn't the Chinese discover America? Why were people so slow to learn the earth goes around the sun? How and why did we begin to think of "species" of plants and animals? How, when, and why did people begin digging in the earth to learn about the past? How did the study of economics begin? These are but a few of the fascinating questions answered by Dr. Boorstin, Librarian of Congress Emeritus.

The Arabic legacy of science and philosophy has long been hidden from the West. British-Iraqi physicist Jim Al-Khalili unveils that legacy to fascinating effect by returning to its roots in the hubs of Arab innovation that would advance science and jump-start the European Renaissance.

Here is the remarkable story of how medieval Arab scholars made dazzling advances in science and philosophy, and of the itinerant Europeans who brought this knowledge back to the West. For centuries following the fall of Rome, Western Europe was a benighted backwater, a world of subsistence farming, minimal literacy, and violent conflict. Meanwhile, Arab culture was thriving, dazzling those Europeans fortunate enough to catch even a glimpse.

An illuminating guide to the scientific and technological achievements of the Middle Ages through the life of a crusading astronomer-monk.

Whether it is Plato's lost city of Atlantis, a technological advanced utopia that sank into the ocean "in a single day and night of misfortune"; the colony of Roanoke, whose early American settlers were swallowed up in the wild forest lands of the unexplored continent, or the Ancient American Explorers, who managed to arrive to the New World 2,000 years before Columbus, the disappearance of these societies is as cryptic as it is implausible. This book will look at cultures of the 10 greatest lost civilizations in history.

Founded by Alexander the Great and built by self-styled Greek pharaohs, the city of Alexandria at its height dwarfed both Athens and Rome. It was the marvel of its age, legendary for its vast palaces, safe harbors, and magnificent lighthouse. But it was most famous for the astonishing intellectual efflorescence it fostered and the library it produced. If the European Renaissance was the "rebirth" of Western culture, then Alexandria, Egypt, was its birthplace.

If you were taught that the Middle Ages were a time of intellectual stagnation, superstition, and ignorance, you were taught a myth that has been utterly refuted by modern scholarship. As a physicist and historian of science James Hannam shows in his brilliant new book, The Genesis of Science: How the Christian Middle Ages Launched the Scientific Revolution, without the scholarship of the "barbaric" Middle Ages, modern science simply would not exist. The Middle Ages were a time of one intellectual triumph after another.
