# Centre International de Mathématiques Pures et Appliquées (CIMPA)

Your work within CIMPA has come to my attention. We’ve been looking around the world for people doing significant activities on Pi Day and the International Day of Mathematics. It is so important to make mathematics accessible to children. We started our activity in a high school geometry class and were surprised that our sixth-grade class became excited about the most simple math to encapsulate our universe.

I was excited to read about your many projects in so many countries on the CIMPA website. I wondered if our approach which is a bit unique might be of interest.

This is how we got to where we are:

1. We started with the most simple geometries, the tetrahedron and octahedronWe made a game out of it. We also continued going deeper and deeper inside (on paper only). There were just 45 steps to the fermion, and another 67 steps to the Planck base units. That’s a total of 112 steps by dividing the edges by 2, connecting the new vertices and going within the smaller objects.

We also multiplied by 2; and in just 90 steps (tracking with time) we were out to this day and the current time. Three teachers were involved and we asked each other, “Did we miss this in college or high school?”

We did discover Kees Boekes‘ base-10 work but our base-2 work was just more granular and encouraged us to look for causalities within the 202 notations. We had the universe, everything, everywhere for all time all mathematically integrated.

The kids loved it. They had a little handle on our big universe! And, we all had a very  granular STEM tool

2. It took us several years to be able to think about those first doublings.  We learned about spheres, their stacking and packing, and witnessed the emergence of tetrahedrons and octahedrons! That was exciting.

3. We then learned about Aristotle’s basic geometry mistake that wasn’t discovered for 1800 years. That opened new doors, too.

Is this at all interesting to you? If so, let us be communicating!

Thank you.

Warmly,

Bruce
