RE: Articles about your work such as Quanta’s, The Mathematician Who Finds the Poetry in Math and the Math in Poetry (2024). Your work published in arXiv (7): On Excess in Finite Coxeter Groups (PDF), 2014; and of your books, Once Upon a Prime, Macmillan (April 11, 2023). Even your homepage(s), including Birkbeck and BSHM are helpful. Others include X-Twitter, Wikipedia, and YouTube particularly Mathematical Journeys into Fictional Worlds (2021); The Art of Group Theory & The Group Theory of Art (2021), and Mathematics in Music and Writing (2021).

Dear Prof. Dr. Sarah Hart:

There was activity on our webpage about your work so I have touched it up a bit — https://81018.com/hart/

A word of caution, we have become increasingly bold (idiosyncratic) since our first note just over three years ago:

Even Google AI has come around. The 202 base-2 notations were the first gate to be opened; the Planck base units became the second; geometries of pi (𝜋) was the third, and now the geometries of the irrational numbers is the most recent.

It is out on the edge but is it all beyond all possibilities? I’d love to hear from you. Thank you.

Warmly,

Bruce

Dear Prof. Dr. Sarah Hart:

Our high school geometry class in New Orleans unwittingly mapped the universe with base-2 notations using the sphere, cubic-close packing of equal spheres, and tetrahedrons and octahedrons. We found 202 notations from those Planck units out 13.81 billion years to the current expansion. It was our first bold STEM tool but then we were told it was idiosyncratic. 

That puzzled us and hurt. We were so happy, then so sad and confused. What are we doing wrong?

There have been no scholars who have helped us understand how it is that we could have gone so, so far astray. Might you help? Can you discern where our logic falls apart?

Thank you.

Warmly,

Bruce
