Mac Onscreen Demo

OnScreen Particle Physics simulates a particle-detection chamber, the device used by researchers at facilities such as Fermilab. By enabling students to carry out simulated experiments, it presents modern physics as a human activity, not just a set of facts. The software is mainly aimed at teachers wanting to teach modern physics from a "how we know" perspective, but it is well suited to individual study. No advanced mathematics required. A particle chamber appears on the screen in 3D perspective. Particle decay events, generated in accordance with the real physics, appear as charged-particle tracks, curved by the simulated magnetic field. Users can rotate the chamber to view tracks from different perspectives and can re-play the event, thus obtaining a vivid picture of it. On-screen tools allow users to solve the puzzle of particle identification exactly as real particle physicists do. Trackmaker, a gamelike, interactive simulation of the motion of a charged particle in a magnetic field is included. This demo version limits user to a single particle event to observe and analyze, but the toolset its complete. Trackmaker is limited to three particles per session. Runs on any Mac with 68020 or greater and system 7.0 or greater.
