Dear Prof. Dr. Geraint F. Lewis:

I sent you a tweet, but whoever sees those tweets? I’ve been reading about your work and now I am reading your work! I’ll be capturing more from your 400 articles, especially those in ArXiv, but I’ll also peruse your books, especially The Cosmic Revolutionary’s Handbook… just what I need!

We are a high school class of geometers who followed a base-2 path down inside the tetrahedron and its octahedron. In 45 steps going deeper and deeper inside, we passed the fermions; and, in another 67 steps, we were in the Planck base units. 

We decided for consistency to multiply the base units by 2, and in 112 jumps, we were back in the classroom and another 90 out to the current expansion and age of the universe. 

We thought it was pretty neat. Nobody else did. Well, Frank Wilczek and Freeman Dyson did until we got serious. Freeman died on us. Wilczek became a god!

I’ll start a page tonight, https://81018.com/geraint-lewis/. At my age, I need as many memory props as it takes! Thanks for all that you have done and all that you are doing. I think the magic of numbers and geometries and their functions will begin to flourish!

Best wishes,

Geraint F. Lewis, @Cosmic_Horizons @Sydney_Uni Go inside the tetrahedron (divide the edges by 2, connect new vertices) and in 45 steps you’ll be among the particles and in another 67 steps you’ll be at the Planck base units. Now multiply those Planck units by two over and over again, 202 times and you have the universe: https://81018.com A little math and geometry go a long way!
