People are now exposed to more information than ever before, provided both by technology and by increasing access to every level of education. These societal gains, however, have also helped fuel a surge in narcissistic and misguided intellectual egalitarianism that has crippled informed debates on any number of issues. Today, everyone knows everything and all voices demand to be taken with equal seriousness, and any claim to the contrary is dismissed as undemocratic elitism.

Claude Shannon was a tinkerer, a playful wunderkind, a groundbreaking polymath, and a digital pioneer whose insights made the Information Age possible. He constructed fire-breathing trumpets and customized unicycles, outfoxed Vegas casinos, and built juggling robots, but he also wrote the seminal text of the Digital Revolution. That work allowed scientists to measure and manipulate information as objectively as any physical object. His work gave mathematicians and engineers the tools to bring that world to pass.

Nikola Tesla (1856-1943), credited as the inspiration for radio, robots, and even radar, has been called the patron saint of modern electricity. Based on original material and previously unavailable documents, this acclaimed book is the definitive biography of the man considered by many to be the founding father of modern electrical technology.

Before the internet became widely known as a global tool for terrorists, one perceptive US citizen recognized its ominous potential. Armed with clear evidence of computer espionage, he began a highly personal quest to expose a hidden network of spies that threatened national security. But would the authorities back him up? Cliff Stoll's dramatic firsthand account is "a computer-age detective story, instantly fascinating [and] astonishingly gripping" - Smithsonian.

Behind the familiar surfaces of the telephone, radio, and television lies a sophisticated and intriguing body of knowledge known as information theory. This is the theory that has permitted the rapid development of all sorts of communication, from color television to the clear transmission of photographs from the vicinity of Jupiter. Even more revolutionary progress is expected in the future.

Regarded as one of the brightest young scientists of his generation, Lewis Dartnell proposes that the key to preserving civilization in an apocalyptic scenario is to provide a quickstart guide, adapted to cataclysmic circumstances. The Knowledge describes many of the modern technologies we employ, but first it explains the fundamentals upon which they are built. The Knowledge is a brilliantly original guide to the fundamentals of science and how it built our modern world as well as a thought experiment about the very idea of scientific knowledge itself.

On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation's collective memory. In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.

The word spread through the hacking underground like some unstoppable new virus: Someone - some brilliant, audacious crook - had just staged a hostile takeover of an online criminal network that siphoned billions of dollars from the U.S. economy. The FBI rushed to launch an ambitious undercover operation aimed at tracking down this new kingpin. Other agencies around the world deployed dozens of moles and double agents.

Gene Kranz was present at the creation of America's manned space program and was a key player in it for three decades. As a flight director in NASA's Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race.

In this absorbing and frequently contentious book, Roger Penrose puts forward his view that there are some facets of human thinking that can never be emulated by a machine. The book's central concern is what philosophers call the "mind-body problem". Penrose examines what physics and mathematics can tell us about how the mind works, what they can't, and what we need to know to understand the physical processes of consciousness.

In The Poisoner's Handbook, Blum draws from highly original research to track the fascinating, perilous days when a pair of forensic scientists began their trailblazing chemical detective work, fighting to end an era when untraceable poisons offered an easy path to the perfect crime.

Who invented beds? When did we start cleaning our teeth? How old are wine and beer? Which came first: the toilet seat or toilet paper? What was the first clock? Every day, from the moment our alarm clock wakes us in the morning until our head hits our pillow at night, we all take part in rituals that are millennia old. Structured around one ordinary day, A Million Years in a Day reveals the astonishing origins and development of the daily practices we take for granted.

Before cell phones that fit in the palm of your hand and slim laptops that fit snugly into briefcases, computers were like strange, alien vending machines. They had cryptic switches, punch cards, and pages of encoded output. But in 1975, a young engineering wizard named Steve Wozniak had an idea: What if you combined computer circuitry with a regular typewriter keyboard and a video screen?

Now, in the first book ever written about this ultrasecretive department, the former director of OTS teams up with an internationally renowned intelligence historian to give listeners an unprecedented look at the devices and operations deemed "inappropriate for public disclosure" by the CIA just two years ago.

Increasing numbers of parents grapple with children who are acting out without obvious reason. Revved up and irritable, many of these children are diagnosed with ADHD, bipolar illness, autism, or other disorders, but don't respond well to treatment. They are then medicated, often with poor results and unwanted side effects. Based on emerging scientific research and extensive clinical experience, integrative child psychiatrist Dr. Victoria Dunckley has pioneered a four-week program to treat the frequent underlying cause, Electronic Screen Syndrome (ESS).

Blockchain technology could affect governance itself by supporting new organizational structures that promote more democratic and participatory decision making. Primavera De Filippi and Aaron Wright acknowledge this potential and urge the law to catch up. That is because disintermediation - a blockchain's greatest asset - subverts critical regulation. By cutting out middlemen, such as online operators and multinational corporations, blockchains run the risk of undermining the capacity of governmental authorities to supervise activities in banking, commerce, law, and other vital areas.

In the final decades of the 19th century, three brilliant and visionary titans of America's Gilded Age - Thomas Edison, Nikola Tesla, and George Westinghouse - battled as each vied to create a vast and powerful electrical empire. In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires.

The Victorian Internet tells the colorful story of the telegraph's creation and remarkable impact and of the visionaries, oddballs, and eccentrics who pioneered it, from eighteenth-century French scientist Jean-Antoine Nollet to Samuel F. B. Morse and Thomas Edison. The electric telegraph nullified distance and shrank the world quicker and further than ever before or since, and its story mirrors and predicts that of the Internet in numerous ways.

Recent years have seen a revival of the heated culture wars of the 1990s, but this time its battleground is the Internet. On one side the alt-right ranges from the once obscure neo-reactionary and white separatist movements, to geeky subcultures like 4chan, to more mainstream manifestations such as the Trump-supporting gay libertarian Milo Yiannopolous. On the other side, struggle sessions and virtue signaling lurk behind a therapeutic language of trigger warnings and safe spaces. The feminist side of the online culture wars has its equally geeky subcultures.
