Zeno’s Paradoxes and Calculus

Source: Zeno of Elea, c. 490-430 BCE; Cauchy, 1821; Weierstrass, 1860s

Finding

Zeno proposed paradoxes of motion: to cross a room you must first cross half, then half the remainder, then half of that — an infinite number of steps. How can an infinite sequence be completed in finite time? The resolution: the infinite series 1/2 + 1/4 + 1/8 + … converges to exactly 1. Not approximately — exactly. The formalization of limits by Cauchy and Weierstrass through epsilon-delta analysis showed that an infinite sum can have a finite, precise value. The paradox rested on the false assumption that completing infinitely many steps requires infinite time.

Pattern Mapping

Proportion — An unbounded process yields a bounded result. Infinity, properly structured, does not overflow into chaos but collapses into precise form. The infinite series has no last term, yet it has a definite sum. Structure contains what would otherwise be unlimited.

Alignment — The convergence means the stated claim (“the sum equals 1”) and the actual behavior of partial sums are consistent; they approach 1 and reach it in the limit.

Non-fabrication — The convergent sum is not an approximation or a convenient fiction. It is exact. The resolution does not paper over the paradox; it reveals that the paradox rested on a false assumption.

Convergence of geometric series is established mathematics. See Boyer, A History of Mathematics (2nd ed., 1991). Philosophical dimensions: Salmon, Zeno’s Paradoxes (1970). The mapping is this project’s structural interpretation.
