Field Notebook
My working notes in classical mechanics, 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.
Amicus Plato amicus Aristoteles magis amica veritas.
Plato is my friend; Aristotle is my friend; but truth is my greater friend.

Study Regions
Current Branches
Three branches organize the notebook: classical mechanics for motion and variational structure; quantum information and computation; and general relativity for geometry, gravity, collapse, and horizons.
Motion
Classical Mechanics Newtonian dynamics, variational principles, symmetry, and the phase-space description of motion.- forces, conservation laws, and constrained motion
- Lagrangian mechanics and the principle of stationary action
- Hamiltonian flow, phase space, and canonical structure
Computation
Quantum Computing Amplitude, interference, measurement, and the conceptual basis of quantum information.- history and foundational concepts
- state evolution and formal structure
- what quantum mechanics lets a computer do
Gravitation
Relativity and Gravitation Classical spacetime geometry, exact solutions, black holes, cosmology, and the threshold of semiclassical gravity.- general relativity as a structured lecture sequence
- collapse, Kerr geometry, and Hawking radiation
- where the classical theory starts to run out

Problemata
Short qualitative questions asked on top of the notebook — read one, commit to an answer, then open the fold. Each solution links back down to the notes where the machinery lives. The collection holds thirteen questions so far — ten from relativity, three from mechanics.
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.
What convinces me is the chain of steps, so I write that down before the conclusion.
Every simplification should say what it drops and why that is allowed.
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.
For motion, symmetry, and variational reasoning, begin with classical mechanics. For states, amplitudes, and algorithms, enter quantum computing. For spacetime, curvature, and horizons, continue to relativity and gravitation.
