从直觉到方程 · From Intuition to Equation
English
Physics asks the most elementary and most elusive questions: why does something move? What is light? What is heat? It took millennia to turn the answers into equations. This column does not catalogue formulas. It tracks the moments when the question itself was replaced.
Before Newton, motion required a continuous push; after Newton, rest and motion were merely two states of the same thing. The thread continues through energy, electromagnetism, and the discovery of fields.

物理学追问最朴素、也最难回答的问题：东西为什么会动？光是什么？热是什么？人类用了数千年，才把答案从直觉变成方程。这个栏目不罗列公式，它追踪那些「整个提问方式被换掉」的时刻。
牛顿之前，运动需要持续的推力；牛顿之后，静止和运动只是同一事物的两种状态。线索还在延伸——能量、电磁学、场的发现，每一步都在重写「力」的定义。
