The canonical originals of “Wakaru” (“It Clicks”) — a reading series for physics-loving high-schoolers and undergraduates. Every series is managed here from now on. Each episode is a self-contained HTML page (serif type + MathJax + live canvas figures + print/PDF ready; the only external dependency is the MathJax CDN).
➡ https://yomei-o.github.io/wakaru_all/
On GitHub’s file pages (github.com/…) the HTML shows up as source. To actually read it and play with the live figures, open the published site (GitHub Pages) above. The links in the tables below also point to the published (rendered) site.
| Series | About | Read (published site) |
|---|---|---|
| Cosmology That Clicks | Read the universe through the speed of light, the fine-structure constant, and gauge symmetry | open |
| Relativity That Clicks | Divide everything by c. β · γ · spacetime interval · E=mc² · simultaneity · gravity = curvature · variable-c ≡ curvature (7 episodes, complete) | open |
| Quantum That Clicks | The story of ℏ. S/ℏ separates classical from quantum: grain & wave, wave function, sum over paths, Schrödinger, uncertainty, measurement (6 episodes + bonus, complete) | open |
| Fields That Click | Why forces travel at the speed of light. Reading fields as “dimensionless ratios” (8 episodes, complete) | open |
| Black Holes That Click | The diagonal of the cube (c · ℏ · G), read through information and bits: horizon · entropy = bit count · Hawking temperature · fastest computer · holography · information paradox (6 episodes + 2 bonus, complete) | open |
| Force That Clicks | Peel back what “force” really is — down to fields, geometry, and symmetry | open |
| Mass That Clicks | What mass actually is | open |
| The Universe Is a Computer | Read the cosmos through the lens of computation | open |
| Learning That Clicks | Evolution, learning, and consciousness read through one and the same gradient | open |
| A History of UNIX That Clicks | The history of UNIX | open |
★ Map of the whole collection: The Physics Cube ── take in every series at a glance along the three axes c · ℏ · G.

Start from the contents page of the published site above and go to each episode. Every individual HTML file just works when opened in a browser (the only external dependency is the MathJax CDN). To print, use each page’s “Print → Save as PDF.”
wakaru-ba-en/ → ../wakaru-chikara-en/index.html), so keep each series in its sibling folder directly under the root.
