# Looking for Math Around the World

As I mentioned already, we are on a math scavenger hunt spree. Last weekend we went to the annual International Festival and searched for math there. Here’s what happened.

Every year we go to the festival. Every year I make a plan to “get some food and watch the dance performances”. And every year I end up walking around, from booth to booth, helping my kid collect country stamps for his passport. Oh, and I get these little puppies, called oliebollen or Dutch doughnuts (so delicious!!!)

This year was no exception… the first day. We went, we saw, we got the stamps, we ate. And then next morning I was like “no, I am marching back and getting my dance performances after all!” Surprisingly, my son was thrilled to go back. I suspect it was the “Japan and 30 years of video games” booth that did it.

Anyway, we got there just in time for the tea ceremony. And because it was early morning and not crowded, we got to taste the tea and the traditional sweets. And then the Rocket boy said that he didn’t get to collect all the country stamps the day before. So he wanted to walk around some more. And I said that it was a good idea, but that maybe we should do something else as well. That’s when he pitched the “let’s look for math” idea. Yep, he knows me really well by now.

We decided that we will walk around and take pictures of anything that is beautiful and mathematical. And these are some of the pictures of math we found over the next 4 hours:

Beautiful symmetries here.

Could this entire pattern be laid out with just one length of braid without doubling up on itself?

Integration and geometry.

One of the many musical instruments we saw (and tried). Math in music is something we haven’t explored… yet.

Symmetry.

Square numbers.

Droste effect.

More patterns.

Patterns, symmetry, frieze math.

Symmetry, Fibonacci numbers.

Geometry, integration, symmetry, and multiplication.

Symmetry, geometric tiling.

Pikachu!!!

Also, we ate some delicious food (Laotian, French, and Greek) and, of course, got some more oliebollen.
