In July, Craig and I presented to the PCMI SSTP (Park City Mathematics Institute Secondary School Teachers Program) during one of the afternoon sessions. I brought him a Math Forum t-shirt (limited edition!) so that we could wear matching outfits.

Craig recently wrote me:

I wore the “What do you notice? What do you wonder?” t-shirt you gave me to school today. Several students in the hallway were intrigued by the fractal dragon (I told them to ask their Geometry teacher about it). The students in my Calculus class noticed the noticing/wondering wording on the shirt and asked me “if I had the shirt specially made.” They thought I came up with the noticing/wondering strategy! I answered them that no, neither did I have the shirt custom-made, nor was I the author of the noticing/wondering… that both shirt and idea came from the Math Forum. I took it as a very high compliment that they would attribute noticing and wondering to me!

Craig’s comment reminded me that we have an activity that we give to teachers who want to show students how to generate the fractal dragon part of our logo.

If you try this activity with your students, let us know how it went! I’m also curious to know if any of them have heard of the book* Jurassic Park* — it’s fun to look at how they used the fractal on the chapter pages. I just found it on Amazon.com and if you use the “Look Inside” feature, view the First Pages, and scroll some you’ll see what I mean.

If you’re wondering about Michael Crichton’s naming convention, you might find Cynthia Lanius’s page interesting: Is It Really The First Iteration? Check out the links in the left sidebar on her page, too. There’s a fun Java applet to try.
