Announcing Euclid's Muse: a new way to Share Mathematics
Geometry Expressions 3.0 can export powerful, interactive HTML5 apps that can be viewed in web browsers. And now, there's a web site where you can upload and share these apps.

Euclid's Muse is to Geometry Expressions what YouTube is to your video camera.

In addition to interactive apps, you can also upload animations and static images exported from Geometry Expressions. Uploads can be public or private, and you can provide them under two flavors of the Creative Commons License.

Check out what's already up on Euclid's Muse, share your favorites, then create a free account and upload some of your own apps!

How to... Export Apps for Euclid's Muse

Problem of the Month
trammel foci problem   
Pictured are two different ways of drawing the same ellipse, one using Archimedes Trammel, and the other using two pins and a piece of string.
Can you relate the distance between the two pins to the length of the trammel handle AB and the distance between the sliders AC?
And how long is that piece of string?

An interactive app which lets you play with this problem is  here on Euclid's Muse.
