An online version of this report is available here.

Here’s a pie chart representation of the time distribution.

Torque

· Latest Version

· Drag brake force character to apply brakes

· On radius graph, display (constant) brake radius

· Added a graph and type-in box for applied force radius application point

· Added record/playback for 4-dimensional applied force value

· Added type in text area for applied force

· Fixed: Can apply force to empty part of the empty ring merry-go-round

· Remaining Work

Lasers

· Latest Version

· Simulation model is paused when laser blows up, model restarts when the user changes the intensity of a beam or resets the entire simulation

· Fixed: "Laser blew up" message erroneously stays in front. Simulation is reset when the user changes a beam rate.

· Notes on last week’s requests

· New parameter settings/slider ranges?

· Results from profiling on slower machines?

States of Matter

· Collaborated with John to initialize States of Matter sim

Misc

· Code style – discussed & standardized style conventions

· Repository – cleaned up phetgraphics demo for future usage

· QM Paper – read and discussed Sam M’s paper

Upcoming Work

· Rotation/Torque

· Collaborate with John on States-Of-Matter

· Licensing issues/Meet with Kate Tallman

· GUI for translation system

· CCK
