Ongoing project: Organizing web pages. To the skeleton was added the javaview applet and Bricard's octahedron.
Other: Backup of work on zip drive and unix.

In the morning I was creating the unfolded figure of a cone, with a geodesic line. I enlarged it, printed it out and made a paper model out of it.It might be an interesting idea to insert a disk into the mathematica model at an angle and see how it slices.
Worked with Joe in Mathematica on the 3D cone figure. Now I need the angle measure of one of the things I drew in Illustrator. How does that measuring tool work...

The measure tool is under the eyedropper tool. Worked with Joe in Mathematica on the cone, this time with the intention of adding the geodesic lines. The morning was filled with my attempts to make the geodesic line computations correct on the circle correct, which did not happen until Joe arrived. The rest of the day was spent using Mathematica to try and create the line on the curved surface of the cone. The biggest obstacle was that it was hard to visualize the unfolded cone angles in correspondense to the Mathematica3D cone base circle. I might want to make a model.

My morning was spent making paper models, trying to get a visualization of how the cone folds, and the relations between the angles. Then the coordinates were plugged into Mathematica. This time, the dots do look like they are in the correct place. I might get the figure done by sometime tomorrow.
For the afternoon, everyone spent time making questions relating to folding and unfolding, of varying difficulty, for 6th graders, that might be used in the eventual class. I worked with Beenish on an unfolding tetrahedra model, first in Mathematica to get the images, then in Illustrator to manipulate it on a page.
