Physics Essay: The Nature of Charge, Principle of Charge Interaction and Coulomb's Law
Bibliographic record
Abstract
What is “electronic charge”? Why there are two kinds of charges? Why do the same charges repel, and dissimilar charges attract each other? Why does their behavior agree with Coulomb's Law? These are among the most basic questions of physics. Let us assume the existence of a kind of microparticle in the universe, which we can call an electon for our purposes here. Three situations are possible: if an object contains a surplus of electons, it will be positively charged; if a deficit of electons, it will be negatively charged; if an object contains electons equal to its expected value, in the saturated state, it is neutral. The charged objects, containing these electons, have the ability to exchange charged or uncharged microparticles in order to achieve a neutral state. The acting force between two charged objects comes from the exchange of charged and uncharged microparticles. The same charges repel, and dissimilar charges attract each other. The value of force is consistent with Coulomb's Law. The material homogeneous between two charged objects affects the value of the acting force between them, but does not affect the direction.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
