Discusses new experiments that are being designed to solve the solar neutrino problem and determine the power source of the sun. (HM)

Discusses the use of laser spectroscopy in determining the presence of specific gaseous constituents. Three of currently used modes for laser detection of pollution are reviewed; (1) long-path measurements; (2) laser raman (differential absorption) measurements; and (3) optoacoustic detection. (HM)

Describes a currently used picosecond spectroscopy system capable of reliably recording picosecond events. Two areas of picosecond research are discussed: one concerns the interaction of electrons in fluids; the second, the primary events in vision. (Author/HM)

Surveys new laser techniques and a variety of spectroscopic experiments that can be used to detect, measure and study very small numbers of atoms on molecules. The range of applicability of these techniques is also included. (HM)

This article describes the distribution of mass in a hand-held object as a fundamental but unrecognized contributor to the sensation one receives from the object. Experiments producing fractions for human sensitivity are given. (SA)

Thermal features of and beneath the surface of a sample can be detected and imaged with a thermal-wave microscope. Various methodologies for the excitation and detection of thermal waves are discussed, and several applications, primarily in microelectronics, are presented. (Author)

Describes the use of atomic spectra that are excited in inductively coupled plasmas for the simultaneous or sequential determination of the elements at all concentration levels. (HM)
