Understanding the concepts of quantum mechanics has always been a challenge for undergraduate students. This is especially so because many of the introductory (analytically solvable) systems and problems discussed in textbooks are seemingly abstract. Using approximate experimental demonstrations of such systems and problems have been shown to be…

Explored is the role of thought experiments in the development of physical theories. Drawing examples from quantum theory it asks how a method that generates no new empirical data can nonetheless exert an influence upon a subject defined by its empiricism. (Author/KR)

Discusses the future of chemical research in the 1980s and the important improvements that will probably occur, particularly in the chemical industry. (SA)

Describes an interactive computer program which allows students to perform simulated quantum measurements on a one-dimensional harmonic oscillator. (SL)
