Perfect for people with busy lives who still want to discover-or rediscover-just how transformative an act of reading can be, these 36 lectures range from short stories of fewer than 10 pages to novellas and novels of around 200 pages. Despite their short length, these works are powerful examinations of the same subjects and themes that longer "great books" discuss.

For the past few hundred years, most of what we’ve been taught about the native cultures of North America came from reports authored by the conquerors and colonizers who destroyed them. Now - with the technological advances of modern archaeology and a new perspective on world history - we are finally able to piece together their compelling true stories. In Ancient Civilizations of North America, Professor Edwin Barnhart, Director of the Maya Exploration Center, will open your eyes to a fascinating world you never knew existed - even though you’ve been living right next to it, or even on top of it.

To better put into perspective the various issues surrounding energy in the 21st century, you need to understand the essential science behind how energy works. And you need a reliable source whose focus is on giving you the facts you need to form your own educated opinions.

"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these 24 lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics.

Nothing has had a more profound impact on the development of modern civilization than thermodynamics.

In The Butchering Art, the historian Lindsey Fitzharris reveals the shocking world of 19th-century surgery on the eve of profound transformation. She conjures up early operating theaters - no place for the squeamish - and surgeons, working before anesthesia, who were lauded for their speed and brute strength. They were baffled by the persistent infections that kept mortality rates stubbornly high. A young, melancholy Quaker surgeon named Joseph Lister would solve the deadly riddle and change the course of history.

In this illuminating audiobook, Tyson and coauthor James Trefil, a renowned physicist and science popularizer, take on the big questions that humanity has been posing for millennia - How did life begin? What is our place in the universe? Are we alone? - and provide answers based on the most current data, observations, and theories.

Consider these commonly held scientific beliefs: Planetary orbits are fixed ellipses; we only use 10 percent of our brains; nothing travels faster than light; a thrown object’s trajectory is a parabola. They seem correct, but they’re all misconceptions that aren’t entirely accurate. There’s much more to the story than you think.
