x = sin(3ωt + δ)·y = sin(2ωt)·δ drifting
One beam · two frequencies · the figure closes only when they are rational
Part-time. Freelance. By engagement. I take a bounded problem and return a bounded answer — scope agreed first, then delivered. The current into the node equals the current out: nothing vague is billed, nothing billed is vague.
Remote, or in London. One consultant, the field theory and the soldering iron in the same pair of hands.
Mathematics
Pure and applied mathematics: modelling, proof, analysis, numerical methods — the algebra running under everyone’s code, inspected by someone who reads it fluently.
Physics
Physics at working depth, not survey depth: electromagnetism from Maxwell’s four lines up, quantum physics from the two slits in. The model, its limits, and what it predicts for your problem.
Electrical Engineering
Electrical engineering: circuits, signals, power, instrumentation. Design review, fault reasoning, and the difference between what the schematic says and what the bench does.
Science & Education
STEM and science education: curricula, courses and materials built from first principles — and the rare service of a difficult thing explained exactly.
Review & Audit
Designs, papers, courses, claims — read closely, faults returned in writing, with the reasoning shown.
Problem‑Solving Sprint
One hard, well-posed problem. Days, not months. If it is not well-posed, posing it properly is the first deliverable.
Education Design
Syllabi, materials, whole courses — built from first principles for schools, companies, or one determined person.
Expert Explanation
Briefings and second opinions: the difficult made exact, then made clear — in that order, never the reverse.

The brief comes by letter. State the problem, the field, and the deadline. If it is bounded, you will get a bounded answer — and if it is not, you will get the bound.
One letter, in your own words — the problem, the field, the deadline, and where to answer.

Rates are agreed per engagement, before any work begins. When they are agreed, payment travels one of three wires. The first is the default.
