_____ In appreciation for Abner Shimony, 2015
Dear Prof. Dr. Gregg Jaeger:
Just now finishing my first read of your most-wonderful tribute to Abner Shimony, let me say as warmly as possible, “Thank you.” Though I thoroughly enjoyed Shimony and learned more than I know, I found him to be a bit aloof, somewhat condescending, and a bit defensive. I think he felt a bit tainted by his close encounters with the people of Maharishi University.
I began attending lectures of the Boston University Center for Philosophy and History of Science in 1971 and got to know Bob Cohen and Marx Wartofsky and some of the other regulars. Because I made an effort to study the work of the scholar who was about to be skewered and sometimes politely shredded, Bob Cohen noticed the most-deferential quality of my rather timid questions. Though an associate within a Cambridge think tank (Synectics Education Systems), my scholarship was weak and here was my new sanctuary for learning from the insiders. Plus, I had begun researching what I called “perfected states in spacetime” and most of my questions had to do with that peculiar combination of concepts.
You have given me a fair amount of work to do! I am now working through all the articles and books you have written on entanglement! So, I thank you again for your scholarship.
PS. A sweet moment in time:
“Shimony is best known for his work in developing the CHSH inequality, an empirically testable form of the Bell inequality, also known as Bell’s theorem. Since 1992, he proposed a geometric measure of quantum entanglement and, along with Gregg Jaeger and Michael Horne, discovered two novel complementarity relations involving interferometric visibility in multiparticle quantum interferometry.”

Dear Prof. Dr. Gregg Jaeger:
I studied with Cohen, Wartofsky and Shimony in the 70s. My last gasp for air was at the Institut Henri Poincaré (1980) with JP Vigier and Costa de Beauregard. My focus was the EPR and Bell. Facing too much headwind, I went back into a business I started in 1972 and eked out a living.
You, on the other hand, are a real scholar and I congratulate you on all that you have done and are doing. Very impressive.
In December 2011, after putting my professional work up on the shelf, I began to pick up on some of those earlier unconstructed ideas while helping a nephew with his high school geometry classes. I had to re-engage Zeno, learn about Max Planck’s base units, then I slowly started reading the latest-and-greatest on entanglement.
Quick question: Do you think that the mathematical-and-dimensionless constants that define the Standard Model are all a little like pi and Euler’s equation in that they are never ending and never repeating? I can’t seem to find a simple answer anywhere. Thanks.
P.S. An Update: At about the same time of this email, another went to Simon Plouffe, the mathematician in Montreal responsible for algorithmically-defining over 11.3 billion irrational numbers. He gave us what seems to be a very reasoned answer.
