Dear Prof. Dr. Ulrike Tillmann:

In 1961 when first studying geometry 101 (just 14 years old), I questioned the completeness of the definitions of points and vertices. What ties those endpoints together? Is there anything inside a point and/or a vertex? 

In 2011 my nephew asked if I would teach his high school classes about Plato’s solids. I had my own special models. By then, having spent time with folks like David Bohm and John Conway, I was still asking odd questions. We followed a Zeno-like path deeper and deeper inside the tetrahedron. Net-net, there were 202 base-2 notations from the first moment of time, Planck Time, to this very moment, right Now. The first 64 notations, below the thresholds of measurement (and perhaps below quantum fluctuations), were a mystery. Each notation had length, time, mass and charge. They also had all the mathematics that defined each Planck base unit. And, I believe they have the qualities of an infinitesimal sphere and the Fourier Transform. I concluded that these notations were not very good point particles and they were not even very good vertices… unless, of course, these were all part of a redefinition of points and vertices

What a strange place to find oneself.
Might you advise me?
Have you ever studied this infinitesimal scale down to the Planck base units?
Thank you.

Warmest regards,

Bruce
