Dear Prof. Dr. Jeffrey Lagarias,

I thank you again and again for your scholarly work. I endorse your work!

Yet, given our work is so idiosyncratic, you probably would prefer that I didn’t.

Notwithstanding, I am glad for *“Mysteries in Packing Regular Tetrahedra.”*

Each day, I wonder what 1800 years of being wrong did to our scholarship.

Best wishes,

Bruce

^{10} Geometric gap: 0.12838822+ radians and 7.35610317245345+° degrees. Even today, March 2020, this gap is little studied and less known. Our first encounter with it was in 2016 upon writing the article, “Which numbers are the most important and why?” At that time, it seemed like Chrysler Corporation had branded that geometry as the pentastar. And though it is a five-tetrahedral representation, they never looked uniquely at the gap of 7.35610317245345+° also defined by 0.12838822+ radians. Two chemists (Frank & Kasper) came closest to opening the discussion in the 1950s. Two academics (Lagarias and Zong) did a preliminary analysis that was a tremendous help; the relation of this gap to the deeper geometries of life remains as a challenge. Our modest start is here: https://81018.com/number/#Pentastar
Some people become larger than life within their own time. Three examples are Aristotle, Newton and Hawking. All three were wrong about one key impression about the nature of life, yet their egos and their position and their person were so illuminated, it became increasingly difficult to challenge their assumptions. Aristotle’s geometric gap, Newton’s absolute space and time, and Hawking’s infinitely hot big bang have each mislead scholarship and we all lost the scent and direction of the chase with its resultant discovery and creativity. Throughout our ever-so youthful human history, such people can readily continue to mislead us. We have to be vigilant to review and re-review all the concepts we hold dear and begin to adjust them appropriately. |

Just a terrific job. A wonderful read.

Thank you.

Coming up on two years now, we still do not know what to do with a simple

little construct: https://81018.com/planck-length-time/ The five tetrahedral construct plays a key role.

Your work gives me a wider and deeper perspective.

Thanks.

Warmly,

Bruce

PS. Long ago I studied with David Bohm, Phil Morrison, and so many others like them, but to make a living, I became a television producer! We had the longest-running television series on PBS stations in the USA and the Voice of America around the world about best business practices. http://smallbusinessschool.org/page18.html

1.** The universe is mathematically very small**. Using base-2 exponential notation from the Planck Length to the Observable Universe, there are somewhere over 202.34 notations, steps or doublings. NASA’s Joe Kolecki helped us with the first calculation and JP Luminet (Paris Observatory) with the second. Our work began in our high school geometry classes when we started with a tetrahedron and divided the edges by 2 finding the octahedron in the middle and four tetrahedrons in each corner. Then dividing the octahedron we found the eight tetrahedron in each face and the six octahedron in each corner. We kept going inside until we found the Planck Length. We then multiplied by 2 out to the Observable Universe. Then it was easy to standardize the measurements by just multiplying the Planck Length by 2. In somewhere under 205.11 notations we go from the smallest to the largest possible measurements of a length.

2. **The very small scale universe is an amazingly complex place**. Assuming the Planck Length is a singularity of one vertex, we also noted the expansion of vertices. By the 60th notation, of course, there are over a quintillion vertices and at 61st notation well over 3 quintillion more vertices. Yet, it must start most simply and here we believe the work within cellular automaton and the principles of computational equivalence could have a great impact. The mathematics of the most simple is being done. We also believe A.N. Whitehead’s point-free geometries should have applicability.

3. **This little universe is readily tiled by the simplest structures**. The universe can be simply and readily tiled with the four hexagonal plates within the octahedron and by the tetrahedral-octahedral-tetrahedral chains.

4. **And, the universe is delightfully imperfect**. In 1959, Frank/Kaspers discerned the 7.38 degree gap with a simple construction of five tetrahedrons (seven vertices) looking a lot like the Chrysler logo. We have several icosahedron models with its 20 tetrahedrons and call *squishy geometry*. We also call it quantum geometry (in our high school). Perhaps here is the opening to randomness.

**5. The Planck Length as the next big thing.** Within computational automata we might just find the early rules that generate the infrastructures for things. The fermion and proton do not show up until the 66th notation or doubling.

I could go on, but let’s see if these statements are interesting to you in any sense of the word. -BEC
