In size and sophistication, the most impressive empire in the Americas was the Incas. Established in Peru in the twelfth century, the Incan empire united millions of people and dozens of distinct cultures under a single governing system. The Incas lacked what many assume are essential to empire-building: writing, the wheel, a favorable climate. Still, the Incas overcame these challenges with incredible science, technology, engineering, and math or STEM innovations. These included terrace agriculture, elaborate road systems, earthquake-proof buildings, a planned economy without money, and an elaborate mathematics communicated with textiles. Incan accomplishments show that technological developments take many unexpected forms and will inspire your readers to think outside of the box.

Over its 2,700-year history, the Maya became one of the most complex and dominant indigenous civilizations in pre-Columbian America. They became masters in science, technology, engineering, and mathematics or STEM, as evident through the archaeological remains that still excite and intrigue people today. The Maya built massive civilizations with temples, palaces, extensive highway networks, and some of the largest pyramids in the world. This splendid book explores all these innovations and more, explaining how, why, and when the Mayan empire's greatest minds came up with unique STEM solutions to everyday problems.

Mostly known today for its complex pantheon and religious rituals, the Aztec empire was also highly advanced in the fields of science, technology, engineering, and math or STEM. With the capital city of the empire built in the middle of a lake, the geographical, political, and economic needs of the Aztecs drove innovation for centuries. Massive construction projects, including ziggurats, causeways, and aqueducts demonstrated that the Aztecs had ambitious goals as well as the STEM knowledge to achieve them. Though much of its history was destroyed, the accomplishments of the Aztecs are an impressive reminder of history's ingenuity.

At the dawn of Europe's Scientific Revolution, China was a major world power. With million-person cities, vast navies, and a robust trade in luxury goods, China was a country of marvels. The "Central Kingdom" was also a country of invention. This fascinating resource explores the science and technology behind China's rise to power: the incredible scope, the unique traditions that supported it, and the reasons for the eventual decline of the dynastic era. Readers will learn of agricultural innovations, massive building projects, elaborate machines, and countless inventions that changed the way the world ate, drank, read, waged war, and traveled.

It's Not Rocket Surgery, It's Brain Science! If you have a brain (spoiler alert: if you're reading this, you do!), you've probably wondered how and why it works the way it does (and why it sometimes...doesn't). What do dreams mean? Why do we fall in love? Can doing brain-teasers make us smarter? What about "smart drugs"? Dr. Alison Caldwell, a neuroscientist and Micah Caldwell, a licensed clinical therapist (and, together, the hosts of the popular YouTube series Neuro Transmissions) are here to answer those questions, and hundreds more you never thought to ask, such as...does your cat really love you? What can therapists learn from TRON? Can my diet make me smarter? Why do some people really like feet? And much, much more. Book jacket.

"In these meditations upon Scripture, the author quickly, lightly opens up the sacred text to us in a way that--to my knowledge--has never been attempted in the entire history of the Christian faith. Through irony, pun, parody, spoof, and joke he reads Scripture with tongue in cheek, a rhyme in his pen, and a smile on his face. If you ever wondered what the Bible would sound like if it were written by Ogden Nash (and who hasn't?), here it is, Charlie Barrett's religious rhymes." --William H. Willimon, acclaimed author and Dean of the Chapel emeritus, Duke University
