This book reinterprets Leonardo da Vinci's mechanical design work, revealing a new level of sophistication not recognized by art historians or engineers. The book reinterprets Leonardo's legacy of notes, showing that apparently unconnected fragments from dispersed manuscripts actually comprise cohesive designs for functioning automata. Using the rough sketches scattered throughout almost all of Leonardo's notebooks, the author has reconstructed Leonardo's programmable cart, which was the platform for other automata. Through a readable, lively narrative, the author explains how he reconstructed da Vinci's designs.

Revered today as, perhaps, the greatest of Renaissance painters, Leonardo da Vinci was a scientist at heart. The artist who created the Mona Lisa also designed functioning robots and digital computers, constructed flying machines and built the first heart valve. His intuitive and ingenious approach--a new mode of thinking--linked highly diverse areas of inquiry in startling new ways and ushered in a new era. In Leonardo's Legacy, award-winning science journalist Stefan Klein deciphers the forgotten legacy of this universal genius and persuasively demonstrates that today we have much to learn from Leonardo's way of thinking. Klein sheds light on the mystery behind Leonardo's paintings, takes us through the many facets of his fascination with water, and explains the true significance of his dream of flying. It is a unique glimpse into the complex and brilliant mind of this inventor, scientist, and pioneer of a new world view, with profound consequences for our times.

Nick and Tesla return in an all-new, robot-filled adventure! When a rash of robberies hits the town of Half Moon Bay, 11-year-old sleuths Nick and Tesla are determined to catch the criminals—but to do so, they'll have to build a host of new gadgets and gizmos! In this robot-themed follow-up to Nick and Tesla's High-Voltage Danger Lab, the brother-and-sister duo build four different droids out of ordinary household objects—and illustrated instructions are included throughout the story, so you can build them, too! Make bristlebots that buzz, hoverbots that float above the ground, battlebots that duke it out, and more! Can Nick and Tesla catch the criminal mastermind—and foil his army of rampaging robots—before it's too late?

Kylie Jean joins the school's robotics team. It's a new challenge, and Kylie has a lot to learn about building robots. She even has to learn how to code. Soon her team enters a big competition. Will Kylie Jean's hard work pay off?

"Padura’s Heretics spans and defies literary categories . . . ingenious." —Maureen Corrigan, Fresh Air A sweeping novel of art theft, anti-Semitism, contemporary Cuba, and crime from a renowned Cuban author, Heretics is Leonardo Padura's greatest detective work yet. In 1939, the Saint Louis sails from Hamburg into Havana’s port with hundreds of Jewish refugees seeking asylum from the Nazi regime. From the docks, nine-year-old Daniel Kaminsky watches as the passengers, including his mother, father, and sister, become embroiled in a fiasco of Cuban corruption. But the Kaminskys have a treasure that they hope will save them: a small Rembrandt portrait of Christ. Yet six days later the vessel is forced to leave the harbor with the family, bound for the horrors of Europe. The Kaminskys, along with their priceless heirloom, disappear. Nearly seven decades later, the Rembrandt reappears in an auction house in London, prompting Daniel’s son to travel to Cuba to track down the story of his family’s lost masterpiece. He hires the down-on-his-luck private detective Mario Conde, and together they navigate a web of deception and violence in the morally complex city of Havana. In Heretics, Leonardo Padura takes us from the tenements and beaches of Cuba to Rembrandt’s gloomy studio in seventeenth-century Amsterdam, telling the story of people forced to choose between the tenets of their faith and the realities of the world, between their personal desires and the demands of their times. A grand detective story and a moving historical drama, Padura’s novel is as compelling, mysterious, and enduring as the painting at its center.

From everyday apps to complex algorithms, Ruha Benjamin cuts through tech-industry hype to understand how emerging technologies can reinforce White supremacy and deepen social inequity. Benjamin argues that automation, far from being a sinister story of racist programmers scheming on the dark web, has the potential to hide, speed up, and deepen discrimination while appearing neutral and even benevolent when compared to the racism of a previous era. Presenting the concept of the “New Jim Code,” she shows how a range of discriminatory designs encode inequity by explicitly amplifying racial hierarchies; by ignoring but thereby replicating social divisions; or by aiming to fix racial bias but ultimately doing quite the opposite. Moreover, she makes a compelling case for race itself as a kind of technology, designed to stratify and sanctify social injustice in the architecture of everyday life. This illuminating guide provides conceptual tools for decoding tech promises with sociologically informed skepticism. In doing so, it challenges us to question not only the technologies we are sold but also the ones we ourselves manufacture. Visit the book's free Discussion Guide here.
