Discusses the microscopic interpretation of thermal conductivity of various forms of matter. Forms considered include gases, metals, and insulators. (JN)

Reviews the theories and fundamental principles of physics as they relate to the comprehensibility of the cosmos. (DKM)

Discusses ten methods for measuring the thermal expansion of solids and the way in which the expansion coefficient relates to other properties of matter. (MLH)

Describes an experiment to measure the thermal conductivity of some gases in an undergraduate physics laboratory using a hot wire method in the pressure range ten to one torr. (HM)

Discusses elementary excitations and their role in condensed matter physics, focusing on quantum plasma, helium liquids, and superconductors. Considers research primarily conducted in the 1950s and concludes with a brief survey of some closely related further developments. (Author/JN)

Designed for individualized use in an applied physics course in postsecondary vocational-technical education, this series of twenty-three learning modules is equivalent to the content of two quarters of a five-credit hour class in electrical technology, electronic service technology, electronic engineering technology, or electromechanical…
