Discussed are two contrasting views about the nature of scientific thinking including Pearson's and Collingwood's. The contexts of questions, methods, problems, experiments, and history are described as contexts of inquiry. The physical thoughts of scientists from pre-Aristotelian times to the present are outlined in relation to contexts of…

Proposes a simple procedure based on an expansion of the exponential terms of Raoult's law by applying it to the case of the benzene-toluene mixture. The results with experimental values are presented as a table. (YP)

Discusses the use of logarithm and reciprocal graphs in the college physics classroom. Provides examples, such as electrical conductivity, reliability function in the Weibull model, and the Clausius-Clapeyron equation for latent heat of vaporation. Shows graphs with weighting of points. (YP)

Suggests that educated persons should be exposed to a body of conceptual knowledge which includes basic principles of the biological and physical sciences. Practical examples involving force, sound, light, waves, and density of water are cited. A lesson on animal tracks using principles of force and pressure is also described. (DH)

Various phenomena in chemistry and biology can be understood through Gibbs energy utilization. Some common phenomena in chemistry are explained including neutralization, hydrolysis, oxidation and reaction, simultaneous dissociation equilibrium of two weak acids, and common ion effect on solubility. (Author/SA)

Describes Bernoulli's equation and Poiseuille's equation for fluid dynamics. Discusses the application of the combined Bernoulli-Poiseuille equation in real flows, such as viscous flows under gravity and acceleration. (YP)

Four questions related to rain concerning aerodynamic drag force, pressure from the impact of raindrops, impact of wind on the pressure, and stopping force extended on the car by the water are proposed. (YP)

Describes an application of methodology based on the Information Integration Theory to study intuitive mastery by 13-14 year-olds of Archimedes' Effect in physics. (Author/YP)

The impact of science on society is examined in this publication's coverage of a series of public lectures that commemorated the 25th anniversary of the National Aeronautics and Space Administration. Edited versions of four speeches are presented which address the impact of science on society from the time of humanity's first significant…

Numerous science and mathematics activities which can be performed with sporks (plastic spoon-forks) that are packaged in cellophane with a napkin and a straw and distributed with school lunches are described. (CP)

Sources for everyday problems are suggested and examples from newspapers are given. Also included are a sample role-playing situation and six other suggested activities. (MK)

Described is the use of an interactive terminal-oriented computing system that has access to files of thermodynamics data. (Author/SA)

Discussed are several topics on medical imaging including x-rays and Computer Assisted Tomography (CAT) scans, magnetic resonance imaging, fiber optics endoscopy, nuclear medicine and bone scans, positron-emission tomography, and ultrasound. The concepts of radiation dosage, electrocardiograms, and laser therapy are included. (YP)

Activities involving concave rubber disks are utilized to illustrate the scientific principles of kinetic and potential energy. Provides teacher instructions and questions related to the activity. (MDH)

Proposes a mathematical computer model for the behavior of liquids using the classical dynamic principles of Sir Isaac Newton and the molecular dynamics method invented by other scientists. Concludes that other applications will be successful using supercomputers to go beyond simple Newtonian physics. (CW)
