Book excerpt: This book studies the transition from local to national timekeeping, a process that led to Standard Time--the world-wide system of timekeeping by which we all live. Prior to the railroads' adoption of Standard Railway Time in 1883, timekeeping was entirely a local matter, and America lacked any uniform system to coordinate times and public activities. For example, in the middle of the nineteenth century, Boston had three authoritative times, which differed by seconds and minutes. The story begins in the 1830s with the building of the first railroads. Since railway safety depended upon maintaining the temporal separation of trains through precise timing, railroads were the first to establish time standards to govern their operations. The railroads' switch to five time standards indexed to the Greenwich meridian inaugurated the modern era of public timekeeping and led directly to cities adopting Greenwich-indexed civil time zones. Central to the story are those college and university astronomers who, starting in the 1850s, sold time signals to nearby cities and railroads. From the start, they competed with other entrepreneurs trying to make money by selling time. Decades of negotiations, government lobbying, and battles over customers followed, all in the name of "public service." Improvements by a host of clockmakers, civil and electrical engineers, telegraph and railway technicians, and instrument makers finally changed the market for accurate time. Public timekeeping became the realm of business investors. Despite the efforts of astronomers and various of their Congressional supporters, who argued for the necessity of a national system of time authorized by the federal government, the railroads' success with their own system blocked legislation for a national system of time until the First World War. By then, a single source for correct time dominated the public's timekeeping: the U.S. Naval Observatory's noon signal. In this first comprehensive, scholarly history of timekeeping in America, the author has drawn upon a rich, untapped archival record, municipal and legislative documents, newspapers, and science and engineering journals to challenge several myths that have grown up around the subject.

Book excerpt: The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem." Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.

Available in PDF, EPUB and Kindle. Book excerpt: What do Scientists Say About Time Travel? It's fair to say that most scientists today will tell you that time travel is impossible. Three of today's top physicists - Charles Liu, Brian Green and Michio Kaku - all hold that time travel is, if not impossible, unlikely in the extreme. However, one of the most brilliant minds of our time, physicist Stephen Hawking, disagrees - although only partially. He believes that time travel is theoretically possible, but only into the future. …. But What Do Real People Experience? The opinion of science, however, has never stopped thousands of people around the world from reporting what they firmly believe are actual experiences of spontaneous time travel! Still others insist that time travel is not only possible, but they have already done it as part of top secret government programmes. Claims for time travel range from the highly flaky to the astoundingly believable. They are especially difficult to dismiss when time travel reports come from absolutely ordinary, rock-solid people who have nothing to gain by proclaiming they travelled in time. Many people who report time travel experiences don't necessarily believe it themselves. What happened to them was so strange, so unexpected, yet so real; they simply have no other good explanation for their experience. You will meet a number of such individuals in this book, most of their stories straight out of the headline of local newspapers. No doubt, a story or two will strike the reader as pure balderdash. On the other hand, some of these cases of time travel are tantalizing and unexplainable. They also come with a certain amount of solid evidence, such as stopped clocks, frozen machines and electromagnetic devices acting in inexplicable ways. Physicist and NASA scientist Tom Campbell said that scientific advances always 'come from the fringe.' Thus, even if you consider some of these stories stepping dangerously 'out there' onto that fringy edge, remember that many of yesterday's fringe theories are today's scientific fact. At the very least, it doesn't hurt to approach the idea of time travel with an open mind and a sense of wonder.

Although time is a feature of the natural world, it is at the same time not natural, but given its meaning by human action and, in our contemporary world, primarily through the law. Rakoff argues that legal regulation of the law has become weaker, with unfortunate results for both individuals and families.

Available in PDF, EPUB and Kindle. Book excerpt: As one of the oldest scientific institutions in the United States, the US Naval Observatory has a rich and colourful history. This volume is, first and foremost, a story of the relations between space, time and navigation, from the rise of the chronometer in the United States to the Global Positioning System of satellites, for which the Naval Observatory provides the time to a billionth of a second per day. It is a story of the history of technology, in the form of telescopes, lenses, detectors, calculators, clocks and computers over 170 years. It describes how one scientific institution under government and military patronage has contributed, through all the vagaries of history, to almost two centuries of unparalleled progress in astronomy. Sky and Ocean Joined will appeal to historians of science, technology, scientific institutions and American science, as well as astronomers, meteorologists and physicists.
