We have Mindstorms to thank for that. In this book, pioneering computer scientist Seymour Papert uses the invention of LOGO, the first child-friendly programming language, to make the case for the value of teaching children with computers. Papert argues that children are more than capable of mastering computers, and that teaching computational processes like de-bugging in the classroom can change the way we learn everything else. He also shows that schools saturated with technology can actually improve socialization and interaction among students and between students and teachers.

    Who thought up paper money? What was the secret element that made the Gutenberg printing press possible? And what is the connection between The Da Vinci Code and the collapse of Lehman Brothers? Fifty Inventions That Shaped the Modern Economy paints an epic picture of change in an intimate way by telling the stories of the tools, people, and ideas that had far-reaching consequences for all of us. From the plough to artificial intelligence, from Gillette’s disposable razor to IKEA’s Billy bookcase, bestselling author and Financial Times columnist Tim Harford recounts each invention’s own curious, surprising, and memorable story. Invention by invention, Harford reflects on how we got here and where we might go next. He lays bare often unexpected connections: how the bar code undermined family corner stores, and why the gramophone widened inequality. In the process, he introduces characters who developed some of these inventions, profited from them, and were ruined by them, as he traces the principles that helped explain their transformative effects. The result is a wise and witty book of history, economics, and biography.

    The event remains one of mankind’s greatest achievements and was witnessed by the largest worldwide television audience in history. In the years since, millions more have had their Earth-centric perspective unalterably changed by the iconic photograph of Aldrin standing on the surface of the moon, the blackness of space behind him and his fellow explorer and the Eagle reflected in his visor. Describing the alien world he was walking upon, he uttered the words “magnificent desolation.” And as the astronauts later sat in the Eagle, waiting to begin their journey back home, knowing that they were doomed unless every system and part on board worked flawlessly, it was Aldrin who responded to Mission Control’s clearance to take off with the quip, “Roger. Understand. We’re number one on the runway.”The flight of Apollo 11 made Aldrin one of the most famous persons on our planet, yet few people know the rest of this true American hero’s story. In Magnificent Desolation, Aldrin not only gives us a harrowing first-person account of the lunar landing that came within seconds of failure and the ultimate insider’s view of life as one of the superstars of America’s space program, he also opens up with remarkable candor about his more personal trials–and eventual triumphs–back on Earth. From the glory of being part of the mission that fulfilled President Kennedy’s challenge to reach the moon before the decade was out, Aldrin returned home to an Air Force career stripped of purpose or direction, other than as a public relations tool that NASA put to relentless use in a seemingly nonstop world tour. The twin demons of depression and alcoholism emerged–the first of which Aldrin confronted early and publicly, and the second of which he met with denial until it nearly killed him. He burned through two marriages, his Air Force career came to an inglorious end, and he found himself selling cars for a living when he wasn’t drunkenly wrecking them. Redemption came when he finally embraced sobriety, gained the love of a woman, Lois, who would become the great joy of his life, and dedicated himself to being a tireless advocate for the future of space exploration–not only as a scientific endeavor but also as a thriving commercial enterprise.These days Buzz Aldrin is enjoying life with an enthusiasm that reminds us how far it is possible for a person to travel, literally and figuratively. As an adventure story, a searing memoir of self-destruction and self-renewal, and as a visionary rallying cry to once again set our course for Mars and beyond, Magnificent Desolation is the thoroughly human story of a genuine hero.
