Abstract
Abstract Electromagnetism and electrodynamics—studies of electricity, magnetism, and their interactions—are viewed as a pillar of classical physics. In the 1820s and 1830s, Ampère founded electrodynamics as the science of mechanical forces associated with electric currents, and Faraday discovered electromagnetic induction. By the mid-19th century, Neumann, Weber, and others in Germany had established an electrical science that integrated precision measurements with a unified theory based on mathematical potential or forces between electrical corpuscles. Meanwhile, based on Faraday’s findings in electrolysis, dielectrics, diamagnetism, and magneto-optic rotation, Faraday and Thomson in Britain explored a theory of the electromagnetic field. In the 1850s and 1860s, Maxwell further developed the Faraday–Thomson field theory, introduced the displacement current, and predicted the existence of electromagnetic waves. Helmholtz’s reworking of these Maxwellian insights led to Hertz’s discovery of electric waves in 1887.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
