Dear Prof. Dr. Annalisa Guerri:

This letter will undoubtedly be among the most naive that you receive today!

We all know that Max Planck’s four basic units were ostensibly ignored by the scientific community for over 100 years. A notable attempt to engage the Planck Length was by a University of Minnesota chemistry professor, C. Alden Mead. I’ll include my overview below.

My interest is in finding a crystallographer who is comfortable within the Planck scale and who has a deep appreciation for the simple interior definition of the octahedron and the tetrahedrons within it.

With all your involvement in the international school and conferences, I thought perhaps somebody would quickly come to mind. I will continue my best efforts by continuing to do online searches today. Thank you.

Most sincerely,

Bruce

**Quick Summary**: These dynamics are our platform to re-engage the Planck Scale.

**The Planck Scale**

Max Planck introduced his fundamental units within his 1906/1914 book, the *Theory of Heat Radiation*.^{a} In 1964 C. Alden Mead finally had an article published that used the Planck Length. Titled *Possible Connection Between Gravitation and Fundamental Length (*Phys. Rev. **135**, B849, August 1964),^{b} it had been held up in peer review for over five years. Nobody quite understood the Planck base units. Mead’s article is the first-known to be published to use the Planck Length. In 1982 John D. Barrow wrote an article, *Natural Units Before Planck*,^{c} mostly a quick study of George Stoney’s work as a precursor for Max Planck’s work to define basic units. In 1985 Thanu Padmanabhan, wrote *Physical significance of planck length *^{d} (Annals of Physics, Volume 165, Issue 1, November 1985, Pages 38-58). In 1992, John Archibald Wheeler compiled *Physics at the Planck Length,*^{e} International Journal of Modern Physics A, Vol. 08, No. 23, pp. 4013-4018 (1993). In 1998 Joseph Polchinski published *Quantum Gravity at the Planck Length*. ^{f} And, in 2001, Frank Wilczek ^{g} wrote a series of three articles for *Physics Today* (*Scaling Mount Planck, I, II, and III* ) about the Planck units and finally the rest of the scientific community really began to take note.

**Platform for the Planck Scale**: Since 2011 we have explored the Planck scale. Since 2016 this exploration has been compiled within this 81018.com website. This is the first time to consider the possible concresence and transformations that could be occurring with cubic close packing, sphere stacking, the Fourier transform, and period doubling. These dynamics raise rather unusual questions about this scale that began with Max Planck’s *Theory of Heat Radiation *^{a}which was followed by the work of these key scholars:^{b} C.
