Dear Prof. Dr. Vladislav Yakovlev:

I am now making my way through your 16 articles posted in ArXiv. Formidable.

I have written about the work of your institute in many places within our website, but only as a footnote! Today, I opened this page to be able to quickly access my notes about your research and the work of your team, and to see copies of my notes to you. I am ever so grateful for your special calculation in November 2017 that placed the attosecond within Notation-84; I noted it here: https://81018.com/a84/

Of course, your work begs the question, “What is the Planck Time?” Our first personal encounter with it was as a secondary benchmark. In 2011 we began following Planck Length and had read that nothing can “logically” be smaller given the very nature of the dimensionless constants, especially pi, and the speed of light. In 2015 we ventured into Planck Time. Gerardus t’Hooft and Stefan Vandoren did a base-10 book about it; we wanted the granularity of base-2 to follow with our path down to Planck Length. There are well over 64 base-2 notations from where you measure in attoseconds and there are around 64-notations from where CERN measures its fermions, quarks and neutrinos. Each of those 64 steps is waiting for us to impute the mathematics of Langlands programs, strings, supersymmetry, loop quantum gravity (LQG), causal dynamical triangulation (CDT), causal set theory (CST), field theories, spectral standard model (SSM), and all the hypothetical particles. It is time to fill in the gap between particle physics and cosmology and quantum physics. So, “What is space?” and “What is time?’ — the two seemingly impossible questions to answer definitively, have blocked us. The really smart people among us tend to argue about it all. Einstein, Newton, Hawking… and now Carlos Rovelli, Nima Arkani-Hamed, and so many others have ideas.

We are simple high school folks who have reverted to an old favorite, pi! I think pi tells us more about what we are missing than anything else. I think it also tells us where we’ve gone off track.

Your comments would be very much appreciated.

Also, do you have any interest in the ISO-naming those intervals down to Planck Time? It seems if left to the *de facto* consensus driven by web usage we may end up with xonosecond, vecosecond, mecosecond, duecosecond, trecosecond, and tetrecosecond.

Thank you, thank you, thank you.

Warmly,

Bruce
