MATH.1:3 - Forces
| Force | Tension |
| Finite description and unbounded reuse | A few generators can produce arbitrarily long paths; listing all paths is usually impossible. |
| Keeping distinctions and economical reasoning | Remembering the generators preserves information, while a later question may need only a quotient or a numerical value. |
| Local compatibility and later use | An endpoint sufficient for today’s composition may hide a condition needed by a changed continuation. |
| Composition and interpretation | Concatenation has laws by construction; a physical or computational interpretation has further conditions of its own. |
