Research Reconstruction
Dirac's corpus is unusually concentrated: the 1924-1948 collected works cover his most productive period, while The Principles of Quantum Mechanics turns research discoveries into a compact symbolic system. This reconstruction extracts recurring work algorithms: q-numbers, transformation theory, bra-ket syntax, spectral observables, relativistic square roots, spinor covariance, field quantization, constrained Hamiltonian dynamics, large-number speculation, and mathematical beauty as a selection rule.
The 300 cases combine early collected papers, later publications and lectures, textbook sections, archive notes, correspondence-style material, and public foundational statements. The strategy tags are intentionally overlapping: one Dirac case can simultaneously use symbolic algebra, Lorentz covariance, and a beauty/unification criterion.

Percentages mean case prevalence: a method used in 180 of 300 cases is shown as 60%. Because each case may use several methods, totals are not expected to sum to 100%.
