Electrodynamics

ModelledLab two-seat table [E] under named hypotheses. Maxwell-as-ontology and ‘free of runaways’ are not public theorems. Hold OPEN.

Maxwell Limit

Laboratory two-seat force at O(v²/c²) is Darwin / Liénard–Wiechert, equal to Coulomb plus a constructed B. Historical Weber is not that table. Radiation and hold stay scoped.

Reading this entry

This entry states the slow laboratory limit as a locked identity: the one-sided map equals Darwin, and Darwin equals Coulomb plus a magnetic field constructed by boosting Coulomb. Historical Weber remains the packaging language of the one-seat hold channel rr̈.

What this is used for

Status and ontology notes use this identity when they need the scored two-seat response at order v²/c². Radiation and hold discussions take the same split, with Darwin and Liénard–Wiechert on the laboratory side and the Weber channel rr̈ kept as the one-seat hold packaging.

Walk through

Under the named hypotheses the locked line is OP-F12 = EM_lab at order v²/c² = DAR = Coulomb + B_boost, with B kept as bookkeeping from a Lorentz boost of Coulomb. Mutual order v/c on the Darwin and Liénard–Wiechert maps preserves Newton's third law for the pair. Bradley aberration sits on this page as the incoming-null relation Δθ=βsinθ. Historical Weber remains in service here as packaging for the one-seat hold book through the channel rr̈. The point Abraham–Lorentz expression is the runaway control carried with that slow-limit identity.

Structure package: Claims here are geometric/packaging results under named premises. They do not by themselves close absolute α, continuum hold, or the full SM mass spectrum. See /status.

Laboratory two-seat electrodynamics at slow speeds is standard relativistic electrodynamics. The scored table of the retarded Liénard–Wiechert force is the Darwin table, equal to Coulomb plus a magnetic field constructed from a Lorentz boost of Coulomb. It is not the historical Weber eight-number table.

Locked laboratory identity (ED-14). is bookkeeping, not a primitive.

Historical Weber is retained as packaging language for the one-seat hold book (the channel). It is not the scored two-seat laboratory force. Retarding Weber on the light cone does not recover Liénard–Wiechert.

Abraham–Lorentz point runaways exist as a control. Finite-size pair-sums need not exhibit that mode. That does not mean the framework is “naturally free of runaways,” and inserting jerk into Weber is not the radiation law.

Mutual keeps Newton’s third law in Darwin / Liénard–Wiechert. Bradley stellar aberration is incoming-null kinematics, — a different operator (DW-ABR). That coexistence does not promote Maxwell as ontology.

[M/O]

Coulomb pin and the Darwin table are scored. Continuum Maxwell PDE, complete-absorber cosmology, and continuum hold remain OPEN. See laboratory two-seat.
