This is the EggMath version 1.5, a collection of web modules (including many interactive applets) covering different topics in mathematics related to eggs; it is intended for use in K-12 classrooms, as in the Chickscope project at the Beckman Institute.

The current modules deal with:

• The Shape of an Egg, which includes discussions of surfaces of revolution and methods for drawing ovals in the plane:

  • Symmetry and Cross-Sections (starting page)
  • Surfaces of Revolution
  • Ellipses with Pins and String
  • Equations for an Ellipse
  • Cartesian Ovals
  • Cassini Ovals

• The White/Yolk Theorem (usually known as the ham sandwich theorem), which shows how any two regions in the plane can be equally divided:

  • Dividing White and Yolk Fairly (starting page)
  • Examples of the White/Yolk Theorem
  • The Borsuk-Ulam Theorem
  • Proof of the Borsuk-Ulam Theorem

• Spherical Geometry, which demonstrates the intrinsic curvature of a spherical surface

• Embryo Calculus, which examines exponential growth, and the number e:

  • Understanding Exponential Growth (starting page)
  • Tangents and Slopes
  • The Number e

EggMath was created by Professors Steve Bradlow and John Sullivan of the UIUC Math Department, with Stuart Levy of the NCSA, and Brian Klamik.

NEW! A version of the EggMath web pages for local installations. Designed for people with slow or unreliable Internet connections, the Standalone Edition combines all the interesting text and applets into one container for easy installation on remote systems. Currently available versions:

.zip file (467K)

For Windows '95/'98/NT, but also expanable by many UNIX systems, and Macintosh systems running Stuffit Expander 5.1.3. We do not support Windows 3.1/DOS systems.

.sea file (474K)

Self-extracting archive for Macintosh systems only.

.hqx file (662K)

Binhexed version of the .sea file. For Macintosh systems only.

.tar.gz file (412K)

GZIP-ed TAR file for UNIX systems. Requires the GNU gzip utility.

Possibilities for future additions include adding more to the section on non-Euclidean geometry (including how to compute surface area of surfaces of revolution), and adding a module on topology (how to distinguish an egg from a donut or a pretzel).

We're always open to other suggestions. Send in your EGGcelent ideas for future modules by email to the development team. Of course, you can always visit the original EggMath website!
