2. What Do Universities Really Owe Industry? The Case of Solid State Electronics at Stanford (EJ797121)
Lecuyer, Christophe
Minerva: A Review of Science, Learning and Policy, v43 n1 p51-71 Mar 2005

Information Analyses; Journal Articles
Descriptors: Electronics; Industry; War; Innovation; Computers; Research Universities; Institutional Role; Public Agencies; Public Policy
Abstract: It is widely argued that, in the United States, the Department of Defense dictated the intellectual contours of academic science and engineering during the Cold War. However, in important ways, American science was also deeply influenced by industry. Between 1955 and 1985, Stanford University embraced three waves of industrial innovation in solid state technology (transistors, integrated circuits, and VLSI systems). As this essay shows, it was these transfers that enabled Stanford engineers to make significant contributions to the expanding fields of microelectronics and computing.

Abstract: This is the second document on the teaching of electronics to appear as part of UNESCO's science and technology education program. An introductory section describes the role that electronics plays as part of the physics curriculum. The following section outlines the content of the electronics course. The outline includes guidelines for determining the course content. The remainder of the document is divided into two parts that present the nine sections of the course. The theme of the three sections in the first part is switching. The theme of the six sections in the second part is integrated circuits. The nine section topics are: (1) useful electronic components; (2) switches; (3) logic circuits; (4) logic gates; (5) bistable circuits; (6) drivers; (7) coding; (8) the pulser, the astable, and the clocked bistable; and (9) counting circuits. Each section contains experiments related to the topic that include investigation questions and notes about the experiment. An attached workbook at the back of the document contains student worksheets for the experiments in each of the sections. Two appendices provide a bibliography and technical details for the electronic modules involved in the experiments.
