The following are links to Mathematica notebooks. To use them
bird.nb (the z.gif animation it produces)
An abstract bird-like thing "flying".birthday.nb
In a group of 23 people, odds are a little better than 50-50 that two or more people will have the same birthday.sc.nb
The odds of guessing which atom in the universe I'm thinking of now are far better than finding a group of 365 random people (from an infinite number of people) who have different birthdays.
One hour short course.SlideShow.nb
probability (one 12-sided vs. two 6-sided dice)
An overview of Mathematica including very a simple comparison of Maple, MATLAB, and Mathematica symbolic math.SurfaceOfRevolution.nb
This uses the SurfaceOfRevolution.m Mathematica Add-On. The notebook is already evaluated. Do not do Kernel => Delete All Output or Kernel => Evaluation => Evaluate Notebook unless you have the Add-On installed.Show curve in 2D, show curve in 3D, show animation of rotating curve around line to make a surface of revolution.
surface of revolution
Needs more work, in particular I want to remove mesh, add line that curve is rotated around, and put curve in red so it wan be seen as it rotates around.
