Set in Edwardian London and on the stormy coasts of Cornwall, Cape Cod, and Nova Scotia, Thunderstruck evokes the dynamism of those years when great shipping companies competed to build the biggest, fastest ocean liners; scientific advances dazzled the public with visions of a world transformed; and the rich outdid one another with ostentatious displays of wealth. [Signature] Reviewed by James L. SwansonIn this splendid, beautifully written followup to his blockbuster thriller, Devil in the White City , Erik Larson again unites the dual stories of two disparate men, one a genius and the other a killer. Late in the 19th century, Europe's most brilliant theoretical scientists raced to unlock the secret of wireless communication.Guglielmo Marconi, impatient, brash, relentless and in his early 20s, achieved the astonishing breakthrough in September 1895. An alchemist and peddler of preposterous patent medicines, he killed his wife, a woman Larson portrays lavishly as a gold-digging, selfish, stage-struck, flirtatious, inattentive, unfaithful clotheshorse. It alternates the story of Marconi's quest for the first wireless transatlantic communication amid scientific jealousies and controversies with the tale of a mild-mannered murderer caught as a result of the invention. The eccentric figures include the secretive Marconi and one of his rivals, physicist Oliver Lodge, who believed that he was first to make the discovery, but also insisted that the electromagnetic waves he studied were evidence of the paranormal. As he and his unsuspecting lover attempted to escape in disguise to Quebec on a luxury ocean liner, a Scotland Yard detective chased them on a faster boat. In an era when wireless has a whole new connotation, young adults interested in the history of scientific discovery will be enthralled with this fascinating account of Marconi and his colleagues' attempts to harness a new technology.

The second genera­tion—powered by blockchain technology—is bringing us the Internet of value: a new, distributed platform that can help us reshape the world of business and transform the old order of human affairs for the better. Though it’s the technology that drives bitcoin and other digital cur­rencies, the underlying framework has the potential to go far beyond these and record virtually everything of value to humankind, from birth and death certifi­cates to insurance claims and even votes. For example, forty-two (and counting) of the world’s biggest finan­cial institutions, including Goldman Sachs, JPMorgan Chase, and Credit Suisse, have formed a consortium to investigate the blockchain for speedier and more secure transactions. Read Blockchain Revolution to understand its profound implications.” —Marc Andreessen , cofounder, Netscape and Andreessen Horowitz “The Tapscotts have written the book, literally, on how to survive and thrive in this next wave of technology-driven disruption. Team Tapscott has stepped up and written the book we’ve been waiting for.” —Dan Schulman , CEO, Paypal “Occasionally a book comes along that changes the global discourse. Blockchains are at the heart of the fourth industrial revolution and the Tapscotts lucidly explain why and how to capture the opportunity and avoid the dangers.” —Klaus Schwab , founder and executive chairman, World Economic Forum “A carefully researched and beautifully written book. “Father and son duo, Don and Alex Tapscott, have impeccable timing.”– Forbes Magazine “The Tapscotts’ make the bulls’ case in clear and compelling terms.” – Fortune Magazine “ Blockchain Revolution is a highly readable introduction to a bamboozling but increasingly important field.”– The Guardian “This is all very new and still unfolding but I recommend that you read Blockchain Revolution …it really is time to get with the global revolution.” – The Huffington Post “The Tapscotts have done a masterful job explaining why this is, truly, another revolution.”– The National Post “The Tapscotts present a mind-expanding perspective – and their enthusiasm makes you a believer in the revolution.” – Thomson Reuters Editor’s Choice: "The definitive, must-read book on a new revolution.”– 800-CEO-READ “This 368-page page-turner offers the first comprehensive look at the future of this emerging digital ecosystem.”– Comstock’s Magazine “Bitcoin is just the beginning.

Originally published in 1985, Neil Postman’s groundbreaking polemic about the corrosive effects of television on our politics and public discourse has been hailed as a twenty-first-century book published in the twentieth century. “I can’t think of a more prophetic, more thoughtful, more necessary – and yes, more entertaining – book about media culture.” –Victor Navasky, National Book Award-winning author of The Art of Controversy “All I can say about Neil Postman’s brilliant Amusing Ourselves to Death is: Guilty As Charged.” –Matt Groening, Creator of The Simpsons “As a fervent evangelist of the age of Hollywood, I publicly opposed Neil Postman’s dark picture of our media-saturated future.

This emerging science can translate myriad phenomena—from the price of airline tickets to the text of millions of books—into searchable form, and uses our increasing computing power to unearth epiphanies that we never could have seen before. It also poses fresh threats, from the inevitable end of privacy as we know it to the prospect of being penalized for things we haven’t even done yet, based on big data’s ability to predict our future behavior. A. Kenn has written about technology and business from Europe, Asia, and the US for The Economist , and is well-connected to the data community. Viktor had researched the information economy as a professor at Harvard and now at Oxford, and his book Delete had been well received. As we wrote the book, we had to dig deep to find unheard stories about big data pioneers and interview them. It is tempting to say that it was predicting exploding manholes, tracking inflation in real time, or how big data saves the lives of premature babies. But the biggest surprise for us perhaps was the very diversity of the uses of big data, and how it already is changing people’s everyday world. Big data improves economic efficiency, but that’s only a very small part of the story. We realized when talking to dozens and dozens of big data pioneers that it improves health care, advances better education, and helps predict societal change—from urban sprawl to the spread of the flu. We are very concerned about what we call in our book “the dark side of big data.” However the real challenge is that the problem is not necessarily where we initially tend to think it is, such as surveillance and privacy. We thought hard to suggest concrete steps that can be taken to minimize and mitigate big data’s risk, and came up with a few ways to ensure transparency, guarantee human free will, and strike a better balance on privacy and the use of personal information. Academic Mayer-Schönberger and editor Cukier consider big data the new ability to crunch vast collections of information, analyze it instantly, and draw conclusions from it.
