Descriptive Reinterpretation of the Equivalence Principle: Weightlessness as an Index-Cancellation Operation

This upload contains a series of research papers providing a "descriptive-engineering" reinterpretation of Albert Einstein’s equivalence principle (1907–1911). The core theoretical framework, based on TASI (Time as Index), formalizes the equivalence principle not as a discovered physical law, but as an index-cancellation operation (\Delta I = 0). By analyzing Einstein’s shift in vocabulary from "interpretation" (Interpretieren) to "essential equivalence" (Wesensgleichheit), these works demonstrate how a descriptive synchronization between an object and a reference frame is eventually relabeled as an ontological property (weightlessness). Key Concepts: 1. Index-Cancellation: Modeling free fall as the synchronization of update sequences to neutralize descriptive differentials. 2. Update Authority: The jurisdiction to select reference frames and control the indexing of traces. 3. Sealing: The external fixing of indices that produces a decoupling between ongoing trace updates and frozen records—a structure isomorphic to both physical systems and contested historical narratives. Beyond physics, this framework functions as an analytical device for Descriptive Engineering, providing "legibility" for domains such as history, politics, and sovereignty. It aims to expose where operational layers have been naturalized into properties and where labels have hardened into apparent ontological facts.
