Drawing Theories Apart

The Dispersion of Feynman Diagrams in Postwar Physics

David Kaiser

University of Chicago Press, 2005

Winner of the 2007 Pfizer Prize from the History of Science Society.

Feynman diagrams have revolutionized nearly every aspect of theoretical physics since the middle of the twentieth century. Introduced by the American physicist Richard Feynman (1918-88) soon after World War II as a means of simplifying lengthy calculations in quantum electrodynamics, they soon gained adherents in many branches of the discipline. Yet as new physicists adopted the tiny line drawings, they also adapted the diagrams and introduced their own interpretations. Drawing Theories Apart traces how generations of young theorists learned to frame their research in terms of the diagrams—and how both the diagrams and their users were molded in the process.

Drawing on rich archival materials, interviews, and more than five hundred scientific articles from the period, Drawing Theories Apart uses the Feynman diagrams as a means to explore the development of American postwar physics. By focusing on the ways young physicists learned new calculational skills, David Kaiser frames his story around the crafting and stabilizing of the basic tools in the physicist's kit—thus offering the first book to follow the diagrams once they left Feynman's hands and entered the physics vernacular.

Faith in a Seed

The Dispersion Of Seeds And Other Late Natural History Writings

Henry D. Thoreau; Edited by Bradley P. Dean; Foreword by Gary Paul Nabhan; Introduction by Robert D. Richardson

Island Press, 1993

Faith in a Seed contains the hitherto unpublished work The Dispersion of Seeds, one of Henry D. Thoreau's last important research and writing projects, and now his first new book to appear in 125 years.

With the remarkable clarity and grace that characterize all of his writings, Thoreau describes the ecological succession of plant species through seed dispersal. The Dispersion of Seeds, which draws on Charles Darwin's theory of natural selection, refutes the then widely accepted theory that some plants spring spontaneously to life, independent of roots, cuttings, or seeds. As Thoreau wrote: "Though I do not believe a plant will spring up where no seed has been, I have great faith in a seed. Convince me that you have a seed there, and I am prepared to expect wonders."

Henry D. Thoreau's Faith in a Seed, was first published in hardcover in 1993 by Island Press under the Shearwater Books imprint, which unifies scientific views of nature with humanistic ones. This important work, the first publication of Thoreau's last manuscript, is now available in paperback. Faith in a Seed contains Thoreau's last important research and writing project, The Dispersion of Seeds, along with other natural history writings from late in his life. Edited by Bradley P. Dean, professor of English at East Carolina University and editor of the Thoreau Society Bulletin, these writings demonstrate how a major American author at the height of his career succeeded in making science and literature mutually enriching.

Skull Shapes and the Map

Craniometric Analyses in the Dispersion of Modern Homo

William White Howells

Harvard University Press, 1989

In this sequel to his Cranial Variation in Man, William White Howells surveys present-day regional skull shapes by a uniform method, examining the nature and degree of cranial differences discernible between recent Homo sapiens populations around the world.
