"The contributors explore two main themes: the challenge of remaining innovative and the necessity of managing institutional boundaries in doing so. The book is organized into four parts, which move outward from individual firms; to networks or clusters of firms; to consultants and other intermediaries in the private economy who operate outside of the firms themselves; and finally to government institutions and politics. "--Editor.
A survey of advances in the field of control engineering from 1930 to 1955, which traces the development of servomechanisms and the electronic negative feedback amplifier, and describes organizations which were developed during World War II to deal with industrial applications.
Recollection by pioneers in radio astronomy, to mark the fiftieth anniversary of extraterrestrial radio emission in 1933.
The invention of the telephone is a subject of great controversy, central is which is the patent issued to Alexander Graham Bell on March 7, 1876. Many problems and questions surround this patent, not the least of which was its collision in the Patent Office with a strangely similar invention by archrival Elisha Gray. A flood of lawsuits followed the patent's issue; at one point the government attempted to annul Bell's patent and launched an investigation into how it was granted. From court testimony, contemporary accounts, government documents, and the participants' correspondence, a fascinating story emerges. More than just a tale of rivalry between two inventors, it is the story of how a small group of men made Bell's patent the cornerstone for an emerging telephone monopoly. This book recounts the little-known story in full, relying on original documents (most never before published) to preserve the flavor of the debate and provide an authentic account. Among the several appendices is the "lost copy" of Bell's original patent, the document that precipitated the charge of fraud against the Bell Telephone Company.
This landmark work chronicles the origin and evolution of solid state physics, which grew to maturity between 1920 and 1960. The book examines the early roots of the field in industrial, scientific and artistic efforts and traces them through the 1950s, when many physicists around the world recognized themselves as members of a distinct subfield of physics research centered on solids. The book opens with an account of scientific and social developments that preceded the discovery of quantum mechanics, including the invention of new experimental means for studying solids and the establishment of the first industrial laboratories. The authors set the stage for the modern era by detailing the formulation of the quantum field theory of solids. The core of the book examines six major themes: the band theory of solids; the phenomenology of imperfect crystals; the puzzle of the plastic properties of solids, solved by the discovery of dislocations; magnetism; semiconductor physics; and collective phenomena, the context in which old puzzles such as superconductivity and superfluidity were finally solved. All readers interested in the history of science will find this absorbing volume an essential resource for understanding the emergence of contemporary physics.
