Dear Prof. Dr. Zeng-Bing Chen:

Today, I have engaged your 2015 ArXiv PDF,
An Informationally-Complete Unification of Quantum Spacetime and Matter,
and I wanted to write to thank you for your scholarship.

The focus of my work in 1972 was the EPR paradox.

Just about the time you were born, I was puzzling that work from 1935.
In 1976 Vicky Weisskopf (MIT) helped arrange for me to meet with J.S. Bell
at CERN.  Even at that time, it seemed that Newton-Leibniz debate was
incomplete and that Leibniz was correct and Newton’s absolute space and
time was not.  I held continuity and symmetry as penultimate.

Carlo Rovelli and Richard A. Muller address the issue of time symmetry
in different ways yet their conclusions are equally startling.  Leibniz
would be pleased.
