mechanics, n.All

Mechanics (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a mesh thrown over the world — square, triangular or hexagonal at our option — supplying the only bricks any building of science may use.

Mechanics (n.) that ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠can describe the world tells us nothing about the world; what tells us something is the precise way it can describe it, and that one system does so more simply than another.
