125353D Simulations of Interacting Particles
http://www.compadre.org/psrc/items/detail.cfm?ID=7402
At the Institute for Science Education, a simulation program named xyZET has been developed and combined with an introductory course in mechanics to demonstrate its usefulness in teaching and learning physics. One of its distinct features enables the visualization of the movement of interacting particles in 3D. It adds value to teaching and learning complex processes, where visualization can help reduce cognitive load. The program can be used during lectures, where a simulation can often speak for itself in place of verbal explanation. The program also supports the development of exercise material for individualized learning. Such material in the form of Web pages can be combined with xyZET simulations, controlled by applets. Its basic features are discussed.General Physics/Computational Physicshttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=7402Mon, 31 Aug 2015 14:46:53 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=7402Something Wonderful This Way Comes [Bootable Cluster CD]
http://www.compadre.org/psrc/items/detail.cfm?ID=7368
Clusters dedicated exclusively for educational purposes are rare, yet most educational institutions have an abundance of PC and Macintosh laboratories. The suggestive name bootable cluster CD (BCCD) offers hope. Indeed, at the BCCD's core is a bootable image that runs completely off dedicated media, which lets us use the BCCD to convert, within minutes, practically any room of Intel- or PowerPC-based workstations into a potent parallel computing environment. What we have here is a comprehensive framework for high-performance computing education, and that, my friends, is the opposite of a failure to communicate. This article elaborates on what lies under the BCCD hood, some uses of the BCCD, and future directions.General Physics/Computational Physicshttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=7368Mon, 31 Aug 2015 14:41:19 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=7368PASCO

http://www.compadre.org/psrc/items/detail.cfm?ID=8662
Nano-science is one of the fastest growing fields in both physics and engineering. It is now possible to design and fabricate devices whose physical dimensions are on the nanometer scale and whose quantum properties can be tuned as desired. In this notebook we will study the quantum mechanics of what are known as reduced dimensional structures. A structure is said to have reduced dimensionality if one or more of the dimensions is on the order of the De Broglie wavelength of the particles confined to the structure. An ordinary wire for example, has no reduced dimensionality since both its length and its radius are large compared to the De Broglie wavelength of room temperature electrons.Quantum Physics/Bound State Systemshttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=8662Tue, 25 Aug 2015 10:48:42 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=8662Understanding the nature of programming, development, and runtime environments
http://www.compadre.org/psrc/items/detail.cfm?ID=8199
This report concerns programming and/or development environments for producing applications, or any application intended only for use in a runtime environment. It provides information about the character of these three environments (programming, development, and runtime) including comparison and contrasts among their "costs" and "benefits." We mean these terms apply to the task of delivering applications to conduct numerical scientific computations.General Physics/Computational Physicshttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=8199Tue, 25 Aug 2015 10:40:37 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=8199Two Approaches to Teaching Computational Physics
http://www.compadre.org/psrc/items/detail.cfm?ID=7403
We can easily argue that all graduates of science and engineering degree programs should have the opportunity to develop good computing skills by the time they complete their studies. However, the depth and range of skills needed varies considerably-even in a single discipline such as physics. Moreover, the interests, backgrounds, and abilities of students taking physics courses vary widely, whereas the number of teachers with scientific computing skills is often limited. Providing appropriate courses for such diverse student groups is thus a challenge.General Physics/Computational Physicshttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=7403Tue, 25 Aug 2015 10:37:29 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=7403Using Computational Methods to Reinvigorate an Undergraduate Physics Curriculum
http://www.compadre.org/psrc/items/detail.cfm?ID=7369
The increased importance of computational methods in physics has made it a must-have skill for undergraduate physics majors. The Austin Peay State University (APSU) Department of Physics and Astronomy has recently reinvigorated its program with the help of the Department of Mathematics by adding small computational components to classes across our curricula, as well as adding a single, required Computational Methods class to the physics major. In addition, we now emphasize a front-to-back problem management approach within our classes; this has required a significant change in the way in which we assess our students performance.General Physics/Computational Physicshttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=7369Tue, 25 Aug 2015 10:35:41 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=7369Portland State Biomedical Physics: Computed Tomography
http://www.compadre.org/psrc/items/detail.cfm?ID=13719
This laboratory exercise uses standard physics laboratory equipment to create an analogy to image formation in Computed Tomography. Objects are placed in an enclosure that is largely opaque in the visible spectrum but mostly transparent to the near infrared light. The enclosure is scanned with a photogate using a rotating platform and an image of the contents is formed. This experiment conveys how an image is formed during a CT scan and highlights the important physical and imaging concepts behind CT such as electromagnetic radiation, the interaction of light and matter, image artifacts, and windowing. Resources provided include learning goals, an assessment, software for creating images, and instructions for assembling the equipment.
