The Infinite Sum

Challenging the Greeks: Can infinity have a final total?

  1. The Logical Gap

    Summing the Unstoppable

    Zeno argued that since there are infinite steps to any destination, the travel time must be infinite. Mathematicians began to wonder if a total could exist.

  2. Ancient Logic

    The Greek Rejection

    Classical thinkers generally believed that adding an infinite number of positive values would always result in an infinite sum.

  3. Geometric Progress

    The Halfway Trail

    Consider a sequence: 1/2, 1/4, 1/8, and so on. Each step is smaller, but the list of steps never ends.
