Proof by Picture

The video discusses a picture proof of a simple number theory theorem, which states that the sum of numbers from 1 to N equals (N^2/2) + (N/2). The speaker explains how a diagram visually represents this theorem, making it understandable for any number N. Despite traditional views that pictures aren't real proofs, the speaker argues that this visual method is as convincing as mathematical induction. The video emphasizes the power of visualization in understanding mathematical concepts.
