Dear Prof. Dr. Dorina Mitrea,
There were several visitors of our page about your work yesterday, so I reviewed and updated that page: https://81018.com/mitrea/ Since my last note in 2023, nobody protested about that geometric gap we uncovered created by five octahedrons — https://81018.com/15-1/ Should we claim it as our own? Then, in March 2025 in discussions with various AI tools, we reduced the four major irrational numbers to a geometry of hexagonals intrinsic to the octahedron. We could find no references to it when we did a literature search. Just recently, we’ve started naming it: ROSS. Grok proposed: Planck Polyhedral Core.
Would you have any advice for us? I hope you find it of interest and that you might comment on these developments. Thank you.
Most sincerely,
Bruce
P.S. If you would like any changes or additions to that page about your work, just say the word! -BEC

Dear Prof. Dr. Dorina Mitrea,
Email is such a poor medium. They get bumped and buried, then misinterpreted. Plus, life is complicated so we forgive and forget. I also review and sometimes revive. After reading your citation from the AMS and Baylor, I know as the department chair you are buried, especially at this time of year. I’ve created a page to remind me about your work and the work of others in the extended Mitrea family. Someday I would love to chat with you about my three questions below. Possible? I hope so.
Warmly,
Bruce
PS. May I add another question? Did pi (π) create number theory before there were numbers?

Dear Prof. Dr. Dorina Mitrea,
The sweet little article, The Magic and Mystery of π (Pi), inspired a look at your homepage, your Wikipedia entry, and your Google scholar docs. There was so much to absorb, I started a reference page for myself: https://81018.com/mitrea/ (that’s this page)
How very special to have three Mitreas… It is obvious why you all are so productive. Congratulations.
With your affections for those of us who got stuck in high school, thank you for all that extracurricular work. It is always thrilling to meet real scholars who are opening special doors to the unknown.
I have questions. Might you have the time for a few?*
Thanks again for all that you do and for the work of the others who inspire you!
Warmly,
Bruce
Editor’s Note at 9:25 AM:
Perhaps we’d start with these three.
1. Do the 100 trillion plus, never-ending digits of pi tell us that continuity is somehow both finite and infinite, a “particular-but-universal quality” of the universe?
2. Do the circle and sphere define a perfection (continuity and symmetry), and might that perfection just be a place where we do not find quantum fluctuations?
3. Does the 1820 work by Joseph Fourier open a third facet of pi, harmony, and might the three concresce to become the first infinitesimal sphere at the Planck scale?
