The energy losses and output of a modern power plant using coal and fuel oil are quantitatively presented. (CP)

Presents some ideas about teaching electromagnetic induction at sixth form level, including educational objectives, learning difficulties, syllabus requirements, selection of unit system, and sequence of material presentation. Suggests the Education Group of the Institute of Physics hold further discussions on these aspects before including the…

Discusses different kinds of material presentation in the teaching of electromagnetism at the university level, including three "classical" approaches and the Keller personalized proctorial system. Indicates that a general introduction to generators and motors may be useful in an electromagnetism course. (CC)

Summarizes the activities undertaken in the 1973 annual conference of the Education Group of the Institute of Physics, including discussions on effective teaching and exhibits brought by member participants. Included are descriptions of the Keller instruction system and the small group method. (CC)

Discusses the procedures of conducting skill sessions in the teaching of physics to undergraduates. Indicates that the interim method can help students in acquiring necessary skills to solve problems but needs further improvement to become more useful. (CC)

Discusses the use of programmed scripts, textbooks, films, and cassette tapes to conduct a self-instruction laboratory course. Indicates the presence of marked positive effects on the development of the students' ability to plan their own experiments. (CC)

Discusses the procedures of using operational amplifiers to conduct student projects and teach physical phenomena such as oscillation, radioactive decay, terminal velocity, projectile and ball bouncing. (CC)

Discusses the flow characteristics of thixotropic and negative thixotropic fluids; various theories underlying the thixotropic behavior; and thixotropic phenomena exhibited in drilling muds, commercial paints, pastes, and greases. Inconsistencies in the terminology used to label time dependent effects are revealed. (CC)

Discusses three experiments, respectively, relating to electricity, optics, and electronics, which provide both the experienced and weaker students with a high interest in determining unknowns from a limited amount of information. (CC)

Summarizes the Darwin theory of x-ray diffraction in thin crystals or crystals with a mosaic texture and its modified application to crystals with three-dimensional electrostatic dipoles. Indicates that the dynamical theory is brought into its present relevance by the improvement of single crystal growth techniques. (CC)

A study of the extent to which Henry was affiliated with the Society and its influence on his work including his evolving relationship with the Society in the scope of the changing nature of American scientific institutions. (DF)
