Pulsars are rapidly spinning neutron stars, the collapsed cores of once massive stars that ended their lives as supernova explosions. In this book, Geoff McNamara explores the history, subsequent discovery and contemporary research into pulsar astronomy. The story of pulsars is brought right up to date with the announcement in 2006 of a new breed of pulsar, Rotating Radio Transients (RRATs), which emit short bursts of radio signals separated by long pauses. These may outnumber conventional radio pulsars by a ratio of four to one. Geoff McNamara ends by pointing out that, despite the enormous success of pulsar research in the second half of the twentieth century, the real discoveries are yet to be made including, perhaps, the detection of the hypothetical pulsar black hole binary system by the proposed Square Kilometre Array - the largest single radio telescope in the world.

Of Clocks and Time takes readers on a five-stop journey through the physics and technology (and occasional bits of applications and history) of timekeeping. On the way, conceptual vistas and qualitative images abound, but since mathematics is spoken everywhere the book visits equations, quantitative relations, and rigorous definitions are offered as well. The expedition begins with a discussion of the rhythms produced by the daily and annual motion of sun, moon, planets, and stars. Centuries worth of observation and thinking culminate in Newton's penetrating theoretical insights since his notion of space and time are still influential today. During the following two legs of the trip, tools are being examined that allow us to measure hours and minutes and then, with ever growing precision, the tiniest fractions of a second. When the pace of travel approaches the ultimate speed limit, the speed of light, time and space exhibit strange and counter-intuitive traits. On this fourth stage of the journey, Einstein is the local tour guide whose special and general theories of relativity explain the behavior of clocks under these circumstances. Finally, the last part of the voyage reverses direction, moving ever deeper into the past to explore how we can tell the age of "things" - including that of the universe itself.

In a world obsessed with the virtual, tangible things are once again making history. Tangible Things invites readers to look closely at the things around them, ordinary things like the food on their plate and extraordinary things like the transit of planets across the sky. It argues that almost any material thing, when examined closely, can be a link between present and past. The authors of this book pulled an astonishing array of materials out of storage--from a pencil manufactured by Henry David Thoreau to a bracelet made from iridescent beetles--in a wide range of Harvard University collections to mount an innovative exhibition alongside a new general education course. The exhibition challenged the rigid distinctions between history, anthropology, science, and the arts. It showed that object-centered inquiry inevitably leads to a questioning of categories within and beyond history. Tangible Things is both an introduction to the range and scope of Harvard's remarkable collections and an invitation to reassess collections of all sorts, including those that reside in the bottom drawers or attics of people's houses. It interrogates the nineteenth-century categories that still divide art museums from science museums and historical collections from anthropological displays and that assume history is made only from written documents. Although it builds on a larger discussion among specialists, it makes its arguments through case studies, hoping to simultaneously entertain and inspire. The twenty case studies take us from the Galapagos Islands to India and from a third-century Egyptian papyrus fragment to a board game based on the twentieth-century comic strip "Dagwood and Blondie." A companion website catalogs the more than two hundred objects in the original exhibition and suggests ways in which the principles outlined in the book might change the way people understand the tangible things that surround them.
