Restored and Annotated — 2026 Edition
A note about this edition
The original manual is preserved substantially as it was written in the late 2000s — voice, jokes, strange capitalization, iPods, movie references and all.
The annotations are new.
They come in four flavors:
2026 CORRECTION — something in the original is factually wrong.
2026 CAVEAT — the intuition is useful, but the literal explanation goes too far.
2026 UPDATE — the technology, history or context has changed.
2026 ASIDE — present-day Omar cannot resist interrupting younger Omar.

A pedagogy of curiosity, agency, productive struggle, and understanding through direct encounter with the world
1. Purpose
Reality-First Pedagogy is an approach to learning built around a simple premise:
People understand deeply when they first encounter a meaningful problem, feel the need to solve it, and then acquire the knowledge, tools, language and abstractions required to make sense of it.
Instead of beginning with terminology, theory, definitions, or a prescribed sequence of content, the learner begins with something real:
Driving Toward Infinity
Drive Toward Infinity
What if singularities aren’t failures of physics, but clues about what comes next?
So apparently I wasn’t finished.
I published a piece about the recent Navier–Stokes singularity result and ended up going down a particular rabbit hole.
The basic thought was this:
If an extraordinarily successful physical theory predicts infinity, perhaps the interesting question isn’t:
How do we get rid of the infinity?
Maybe it’s:
What assumption broke immediately before we got there?
