About Platonic Realms

Originally with a URL of mathacademy.com, this website came online in 1997 as a project of graduate students at the University of Colorado, Boulder. Maintained and expanded by B. Sidney Smith, Platonic Realms grew into a destination for math students at the high school and undergraduate levels, offering an encyclopedia, articles, and special downloads. After languishing for many years the site is now being renewed and expanded using up-to-date technology to serve the interests of all who love mathematics.

We are always delighted to hear from our visitors, whether corrections, suggestions, or just a comment.

About Cookies

Cookies are essential to the successful operation of this web site. A functional shopping cart application, for instance, is all but impossible without them. Platonic Realms additionally uses Google Analytics to track site usage, and consequently users will have cookies placed and tracked by Google. (Some such tracking cookies will appear on any professionally maintained website—we are not unusual in this regard.) Also, Platonic Realms allows our sponsors to track ad-views with cookies. However, sponsors are forbidden from using any third-party tracking cookies. If any of our visitors become aware that third-party cookies are being placed, we would appreciate being notified so that we may enforce this policy. Finally, users who make purchases on this site may expect cookies to be placed by PayPal. Platonic Realms itself uses only session cookies, which are automatically deleted when you close your browser.
