Field Notebook

My working notes in general relativity and quantum computing. I write the derivations out in full and keep them, so the reasoning stays recoverable when I come back to a topic.

Plato is dear, but truth is dearer.

Study Regions

Current Branches

Two areas are developed enough to be worth reading. One is quantum information and computation; the other is general relativity — geometry, gravity, collapse, and horizons.

Method

How the notebook works

These notes try to keep the working visible — the definitions, the assumptions, and the places where the reasoning jumps — so I can check them again later.

Derive first

What convinces me is the chain of steps, so I write that down before the conclusion.

Name the approximations

Every simplification should say what it drops and why that is allowed.

Write for return

I expect to come back and correct these, so I write them to be reopened.

Suggested Entry

Start from whichever branch you want to think with.

If the question is about states, amplitudes, and algorithms, start in quantum computing. If it is about spacetime, curvature, or horizons, start in relativity and gravitation.
