Where is PI on the Number Line?

[Run the Applet]
Note:  This applet uses a farily recent version of Java. As many browsers are not yet up to date, it is set up to use
         Sun's Plug-in for Java (and will prompt you with how to install it if you don't already have it).

Note to Students and Teachers:
This applet was motivated by a discussion on LinkedIn and extends a model of the geometric "rolling circle" approach (implemented in Geogebra by Sanjay Gulati for example) with the additional capacity for zooming in on the exact location to show that, no matter how closely we look,  it never exactly matches any exact decimal value.

Note to Developers: The applet linked to above was built with the  GeX component library which is intended to support the quick construction of demonstration tools for mathematics instruction.
