This paper has two parts. In the first part, intended for physics students as well as for engineering students whose primary interest is not physics, a new lesson related to shadow properties is given as a part of lectures on light. The effects resulting from a shadow 'motion' observed on a screen were looked into. The relationship between the…

Infinite ladder circuits are often encountered in undergraduate electrical engineering and physics curricula when dealing with series and parallel combination of impedances, as a part of filter design or wave propagation on transmission lines. The input impedance of such infinite ladder circuits is derived by assuming that the input impedance does…

Advances in the biological sciences necessitate the training of chemical engineers to translate these fundamental discoveries into applications that will benefit society. Accordingly, Tulane University revised its core chemical engineering curriculum in 2005 to include a new introductory course in bioengineering and biotechnology for sophomores.…

Presented is a review of the literature on the development of university and industry research cooperation and conflict up to the early 1980's. The founding of both research universities and industrial America, two world wars, the space race, and protest movements provide points of reference for this period. (MVL)

Described are the essential elements of memos; suggested are a basic format for organization, and two problems to which technical specialists' memos seem particularly susceptible. Included is a memo assignment used in senior design classes and professional development seminars. (MVL)

Describes some of the features of Lehigh University's (Pennsylvania) process modeling and control program. Highlights the creation and operation of the Chemical Process Modeling and Control Center (PMC). Outlines the program's philosophy, faculty, technical program, current research projects, and facilities. (TW)
