SWhat changed
A compact deterministic model made sensitive, nonperiodic dynamics concrete.
Scientific scope
Lorenz's 1963 paper; later formal chaos theory and butterfly terminology not assigned wholesale.
Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1963 Journal of the Atmospheric Sciences paper and its model. Earlier nonlinear dynamics, later terminology such as the butterfly effect, strange-attractor theory and atmospheric predictability studies remain separate.
