The site is organised into five parts: mechanics, thermodynamics, electrostatics and circuits, waves, twentieth-century physics. Each part gathers numbered chapters that close with the exercises. The order is designed for a linear reading, but the links between atoms let you jump freely from one topic to another: many ideas (energy, the oscillator, fields) run across several parts.
Each page is an atom — a short note on a single concept — linked to the others. To move around you have several tools, all reachable from the top bar or the sidebar.
- Sidebar (on the left): the tree of chapters and sections, to navigate at a glance; it can be collapsed to read full-page.
- Search (at the top): search by keyword across all the atoms — it replaces the printed analytic index.
- Knowledge graph: eight cross-cutting dimensions — Concepts, Methods, Objects, Skills, Topics, People, Simulations and Video — that link the atoms beyond the order of the chapters. In particular the Methods collect the standard solving procedures (free-body diagram, dimensional analysis…), and the People add a historical dimension with the scientists’ profiles.
- Tags: every atom carries clickable labels (topic, concept…) that open the list of all the related pages.
- Backlinks and mini-graph: at the bottom of each page you find which other atoms refer to it and a local map of the links.
- Add to PDF: assembles on the fly a printable handout with the atoms you need.
- IT/EN language, light/dark theme and reader mode: in the top bar.
There is no single formulary: the key formulas by area are collected in the exam (maturità) appendix, and the recurring numerical values in the Quick reference page of this guide.
