Book excerpt: The national laboratories have occupied a central place in the landscape of American science for more than fifty years. Deeply researched and lucidly written, The National Labs is the first book to trace the confluence of diverse interests that created and sustained this extensive enterprise. Westwick takes us from the origins of the labs in the Manhattan Project to their role in building the hydrogen bomb, nuclear power reactors, and high-energy accelerators, to their subsequent entry into such fields as computers, meteorology, space science, molecular biology, environmental science, and alternative energy sources.
