From the city sundials of ancient Rome to the era of the smartwatch, clocks have been used throughout history to wield power, make money, govern citizens and keep control. Sometimes, also with clocks, we have fought back. In About Time, time expert David Rooney tells the story of timekeeping, and how it continues to shape our modern world. In 12 chapters, demarcated like the hours of time, we meet the greatest inventions in horological history, from medieval water clocks to monumental sundials, and from coastal time signals to satellites in Earth's orbit.

In the years surrounding WWI, the basic models of many technologies we use today were invented and introduced en masse.

The iconic British television series Downton Abbey provides a glimpse into this period of societal change. Whether you are a fan of the television series or not, the examples in this audiobook provide practical advice to effectively manage technological and cultural change.

For most of human existence, people lived in a somewhat similar fashion. Everything that has been produced, from food and raw materials to clothing and other finished products, has been done either solely by hand or with some help of animal power. This was the same across the eras and throughout the world, no matter how advanced or backward the various civilizations were. Yet, our lives today couldn’t be more different.

Jay Gallentine delivers a quirky and unforgettable look at the lives and legacy of the Americans and Soviets who conceived, built, and guided those unmanned missions to the planets and beyond.

From the printing press to the television, social movements have leveraged communications technologies to advance change. In this moment of rapidly evolving communications, it's imperative to assess the role that the internet, mobile devices, and social media can play in promoting social justice.

De toute éternité, les communications à distance, les télécommunications, se sont avérées essentielles pour les humains. Selon les époques, elles ont fait appel à l'imagination ou à l'ingénierie, et toujours de manière industrieuse. Ainsi, les trompettes, les tambours, la fumée ou le langage sifflé transmettaient des messages aux populations locales bien avant l'avènement du télégraphe optique, du télex ou de la téléphonie.

Outposts on the Frontier reveals how the Soviets and the Americans combined strengths to build space stations over the past 50 years. At the heart of these scientific advances are people of both greatness and modesty. Jay Chladek documents the historical tapestry of the people, the early attempts at space station programs, and how astronauts and engineers have contributed to and shaped the ISS in surprising ways.

Homesteading Space is more than a story of technological and scientific success; it is also an absorbing, sometimes humorous, often inspiring account of the determined, hardworking individuals who shepherded the program through a near-disastrous launch, a heroic rescue, an exhausting study of Comet Kohoutek, and the lab's descent into the Indian Ocean. Featuring the unpublished in-flight diary of astronaut Alan Bean, it is replete with the personal recollections and experiences of the Skylab crew and those who worked with them in training, during the mission, and the return.

Brilliant offers a sweeping view of a surprisingly revealing aspect of human history - from the stone lamps of the Pleistocene to the LEDs embedded in fabrics of the future. Jane Brox plumbs the class implications of light - who had it, who didn't - through the many centuries when crude lamps and tallow candles constricted waking hours. Brillant is infused with human voices, startling insights, and - only a few years before it becomes illegal to sell most incandescent light bulbs in the United States - timely questions about how our future lives will be shaped by light.

The intercontinental ballistic missile (ICBM), designed to quickly deliver thermonuclear weapons to distant targets, was the central weapons system of the Cold War. ICBMs also carried the first astronauts and cosmonauts into orbit. More than a generation later, we are still living with the political, technological, and scientific effects of the space race, while nuclear-armed ICBMs remain on alert and in the headlines around the world. Christopher Gainor explores the US Air Force's decision, in March 1954, to build the Atlas, America's first ICBM.
