John Boslough Knihy

Presents forty-nine national parks, from Alaska's Denali to Wyoming's Yellowstone, including information on each park's appearance, location, date of founding, size, terrain, sights, wildlife, activities, services, and history

Here is an intimate glimpse of the greatest scientist of our day, the brilliant physicist confined to a wheelchair whose A Brief History of Time has become the first worldwide scientific bestseller of the century. The story of Stephen Hawking's relentless quest for the secret of the origins of the universe will change forever the way you look at the stars . . . and your place among them.

Masters of Time chronicles the sudden unraveling of modern cosmology from its heyday in the early 1980s, when the ultimate secret of the origin of the universe seemed all but in hand, to the confused scientific picture of the 1990s. By following each major theory from its origins to the point at which it is overtaken by contradictory or nonexistent evidence, Boslough offers the clearest explanation ever offered of what we know and still do not know about the origin and structure of the universe.
