New: "The Primordial Mark" — one operation (drawing a distinction) generates the ultrametric tree underlying spin glasses, p-adic numbers, QCD jets, and the Classification of Finite Simple Groups.

The CFSG is exhaust. The engine is the Mark.

The Primordial Mark: From a Single Distinction to the Infinite Tree of Mathematics

This document presents a convergent synthesis across logic, number theory, geometry, and group theory, unified by a single primitive: the act of drawing a distinction, the Mark. Includes PDF version. License: https://github.com/QNFO/license/

It's almost 50 years now since I first encountered the volumes of Peirce's “Collected Papers” in the math library at Michigan State, and shortly afterwards a friend called my attention to the entry for Spencer Brown's “Laws of Form” in the Whole Earth Catalog and I sent off for it right away. I would spend the next decade just beginning to figure out what either one of them was talking about in the matter of logical graphs and I would spend another decade after that developing a program, first in Lisp and then in Pascal, that turned graph‑theoretic data structures formed on their ideas to good purpose as the basis of its reasoning engine.

I thought it might contribute to a number of long‑running and ongoing discussions if I could articulate what I think I learned from that experience.

So I'll try to keep focused on that.

#engineering #lawsofform

This thing all things devours:
Birds, beasts, trees, flowers;
Gnaws iron, bites steel;
Grinds hard stones to meal;
Slays king, ruins town,
And beats high mountain down.

— Tolkien • The Hobbit

Talking about time is a waste of time. Time is merely an abstraction from process and what is needed are better languages and better pictures for describing process in all its variety. In the sciences the big breakthrough in describing process came with the differential and integral calculus, that made it possible to shuttle between quantitative measures of state and quantitative measures of change. But every inquiry into a new phenomenon begins with the slimmest grasp of its qualitative features and labors long and hard to reach as far as a tentative logical description. What can avail us in the mean time, still tuning up before the first measure, to reason about change in qualitative terms?

Et sic deinceps … (So it begins …)

Two things impacting my studies of Peirce and Spencer Brown over the years were my parallel studies in mathematics and computer science. In the overlap between those areas came courses in logic, mathematical linguistics, and the theory of formal languages, grammars, and automata.

My intellectual wanderings over a nine‑year undergraduate career would take me through a cycle of majors from math and physics, to communication, psychology, philosophy, and a cross‑cultural liberal arts program, then back to grad school in mathematics.

The puzzles Peirce and Spencer Brown beset my brain with were a big part of what drove me back to math, since I could see I had no chance of resolving them without learning a lot more algebra, logic, and topology than I had learned till then.

Connections: All this RFK fluoridation talk resulted in me starting a re-read of "The Schrodinger's Cat Trilogy." That reminded me I have for decades meant to look into "Laws of Form." Suddenly I am confronted with the enormity of x-squared plus one equals zero and the need for imaginary numbers.

The...NEED...for imaginary numbers. That's as far as I've got:
