I am an independent IB and A-level physics teacher, software developer, and theoretical physics researcher.
Notes on learning and researching theoretical physics, especially gravity and cosmology.
This article introduces a stability-driven approach to constructing $F(R)$ dark energy models. By studying the functional properties of $F_R(R)$, this work identifies the sigmoid structure underlying the Appleby–Battye model, develops new globally stable model families, and discusses their implications for dark energy–inflation unification.
Why jerk and higher time derivatives are usually derived rather than independent variables in common mechanical models, with examples from field theory and engineering.
Definitions of mechanical motion and applicable frameworks: classical mechanics, thermodynamics, field theory, relativity, and quantum field theory.
How the role of time changes across classical mechanics, relativity, thermodynamics and cosmology, and quantum gravity.
Notes from IB and A-level Physics teaching: explanations, problem breakdowns, and learning paths that have held up in practice.
A chapter-by-chapter glossary of core IB Physics and mathematical terminology, with UK and US IPA pronunciations and precise English definitions.
An introduction to the command terms used in IB Physics examinations and the scientific investigation, with guidance on producing accurate, relevant and physically supported responses.
This article outlines core skills in experimental design, data collection, uncertainty propagation, graphical analysis, and evaluation for IB Physics.
A concise overview of DSE, IGCSE, A-Level, IB DP, and AP, plus differences among CIE, Edexcel, and Oxford AQA for A-Level/IGCSE.
Study notes on programming, plus personal projects such as plugins and desktop apps.
An Obsidian plugin for writing LaTeX with customizable chord shortcuts and a formula panel, plus live preview, display environments, and safe delimiter normalization.
A lightweight Windows diagnostics and real-time monitoring tool that brings network, audio, removable storage, Bluetooth, driver, blue-screen, and port troubleshooting into one clear workflow.
Local Astro commands, build output, and deployment to a personal server via GitHub Actions and rsync.
Git commands for repository setup, daily commits, branches, tag releases, undo, and conflict resolution.
