Progressive depth

Read the essentials first

Essential remains visible as the starting point. Open Understand, Deepen, and Explore when you need application, formalization, or connections for the same concept.

  1. EssentialA correct, self-contained minimum idea.
  2. UnderstandPhysical interpretation and connections.
  3. DeepenDerivations, conditions, and rigour.
  4. ExploreExtensions for further study.

Academic scope

Sources and models

The official syllabus governs the stable curricular scope, and the unit sequence organizes the course's order and depth. The examples, exercises, and diagrams in this implementation are original.

Equations are presented with their conditions of application. A mathematical relation does not replace an explicit choice of model.
