SICM — An Executable Reading Edition

Read Structure and Interpretation of Classical Mechanics where its central claim can run in the browser. This shelf begins with the complete preface and Chapter 1, in the English source text and a Korean reading translation.

Every reading page names the exact upstream revision and exposes both its corresponding Org source and adaptation status. The prose, translation, and Homepage computation are distinct evidence layers.

One sentence, one calculation

“Classical mechanics is deceptively simple.”
— Gerald Jay Sussman and Jack Wisdom, Structure and Interpretation of Classical Mechanics, 2nd edition

Harmonic-oscillator Lagrange residual READY

(do
  (require '[emmy.env :as e])
  (defn L-harmonic [m k]
    (fn [local]
      (let [q (e/coordinate local)
            v (e/velocity local)]
        (e/- (e/* (e// 1 2) m (e/square v))
             (e/* (e// 1 2) k (e/square q))))))
  (e/simplify
   (((e/Lagrange-equations (L-harmonic 1 1)) e/cos) 't)))

For the path q = cos(t) with m = k = 1, the Euler–Lagrange residual evaluates to exactly zero. Chapter 1 continues from this scalar receipt to a computation-derived view of Figure 1.1.
