Physics Derivation from Primary Literature
8 weeks · 0 milestones
Select a named primary physics paper (arXiv, Physical Review, Nature Physics, or equivalent) and work through a key derivation from that paper step by step — filling in all algebraic and physical reasoning steps that the authors compressed or omitted. Document every step with physical justification, identify approximations and their domain of validity, and write a brief assessment of what the derivation assumes and therefore cannot claim. This is fully accessible — arXiv (free), Physical Review Letters open access, and many Nature Physics papers are freely available. Reviewed by a physicist who selects a second related paper during the review session and asks you to identify the key step in a derivation you have not previously seen — requiring you to demonstrate that you understand the methodology, not just the specific paper you prepared.

Choose a specific physics result from primary scientific literature — a paper on arXiv, Physical Review, or an equivalent peer-reviewed source — and identify the key derivation you will work through. The derivation must be non-trivial: a result that requires multiple steps, connects two physical concepts, or involves a technique not taught at introductory level. Map the structure of the derivation at a high level before working through it in detail, so that the overall logical structure is understood before the algebra begins.
Proof required
Submit the full citation of the primary paper you have selected, a statement of the specific result or derivation within it that you will work through, and a high-level step map showing the key logical stages of the derivation (what physical assumptions are made, what mathematical technique is applied at each stage, and what the intermediate results are before the final result).
What gets checked
- The selected result is from an identifiable primary literature source — a published or preprint paper with authors, title, and journal or arXiv reference; not a textbook derivation
- The derivation is non-trivial — it requires more than three substantive steps and involves at least one technique above introductory-level physics (variational methods, perturbation theory, Green's functions, renormalisation group, tensor notation, or equivalent)
- The step map distinguishes physical assumptions from mathematical manipulations — the two are different and a physics derivation requires clarity about where each type of reasoning is applied
