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.
