Dear Colleagues and Students,

I enjoyed my visit to Arizona very much.  Thank you for the warm welcome and for being so receptive to the material I presented. 

Below you will find links to the transparencies I used during the talks at Phoenix College's Mathapalooza, and the ArizMATYC Conference. I have also included links to some of the sites I showed or mentioned during the presentations.  I hope you will try some of the transparencies in your classes, and that you give yourself permission to use five minutes of any class period for whatever you find interesting in, and around, mathematics.

Links to Other Sites

Postage Stamps of Mathematicians This page contains postage stamps involving mathematics.  You will find many things here that you can use in class.

Sierpinski Zoom Movie   This page has the zoom movie of the Sierpinski triangle.

Fractal Zoom Movies  Toward the bottom of this page is the free movie player that you can download to play the other fractal zoom movies the were shown in the presentation.

Merriam-Webster Online Dictionary  This is the Merriam-Webster online dictionary.  If you have on-line access in your classroom, this is a good place to go to look up definitions during class.  For example, look up the definition for scientific notation.  I think you will like it.

Stages of the Sierpinski Triangle   This site will let you see each stage of the Sierpinski triangle with a few clicks of your mouse.
