An interview with the award winning author can be found in About us at Phet VideoPhET provides fun, interactive, research-based simulations of physical phenomena for free. We believe that our research-based approach- incorporating findings from prior research and our own testing- enables students to make connections between real-life phenomena and the underlying science, deepening their understanding and appreciation of the physical world. To help students visually comprehend concepts, PhET simulations animate what is invisible to the eye through the use of graphics and intuitive controls such as click-and-drag manipulation, sliders and radio buttons. In order to further encourage quantitative exploration, the simulations also offer measurement instruments including rulers, stop-watches, voltmeters and thermometers. As the user manipulates these interactive tools, responses are immediately animated thus effectively illustrating cause-and-effect relationships as well as multiple linked representations (motion of the objects, graphs, number readouts, etc.) PhET Interactive Simulations, University of Colorado, http://phet.colorado.edu http://www.merlot.org/merlot/viewMaterial.htm?id=88586 An effective tool to help students learn about all aspects of the ideal gas law. One of the best web gas law simulations. http://www.merlot.org/merlot/viewMaterial.htm?id=90161 This applet presents a simulation of four simple transformations in a contained ideal diatomic gas. The user chooses the type of transformation and, depending on the type of transformation, adds or removes heat, or adjusts the gas volume manually. The applet displays the values of the three variables of state P, V, and T, as well as a P-V or T-V graph in real time. http://www.merlot.org/merlot/viewMaterial.htm?id=75146 This calculator is designed to replace tables (e.g. NACA 1135) in performing basic compressible aerodynamics calculations. It is designed for those learning, teaching or using compressible aerodynamics. It computes (both forward and backward) isentropic flow, normal shock and oblique shock relations. It also has a scratch pad for doing the additional arithmetic usually needed to solve compressible aero problems. http://www.merlot.org/merlot/viewMaterial.htm?id=74345 A simulation of the kinetic theory of gasses. Students can study the dependence of the mixing of two gasses on temperature and pressure. This material includes several virtual labs for students to perform. http://www.merlot.org/merlot/viewMaterial.htm?id=90443 Physlet for demonstrating black body radiation. http://www.merlot.org/merlot/viewMaterial.htm?id=90210 This online tutorial explains the theory of Brownian motion. Illustrations of this motion are provided by both a movie and a java animation. http://www.merlot.org/merlot/viewMaterial.htm?id=647878 Interactive tutorials based on simulations involving all topics in introductory physics. This is developed to support the 11th edition of Young and Freedman's calculus-based physics textbook. http://www.merlot.org/merlot/viewMaterial.htm?id=90425 The motion of an object placed in a fluid is simulated. The densities of the block and fluid, and the coefficient of friction between the block and fluid, can be changed. Oscillatory motion is seen as the block comes to rest, in cases where it can float. http://www.merlot.org/merlot/viewMaterial.htm?id=90625 Illustration of the concepts of the Fermi Level, Density of States, and carrier concentrations in semiconductors. Includes both applet and tutorial, including worksheet, references, quiz, and SPICE model.
