In his Introduction to Arithmetic, Nicomachus of Gerasa (c 100 A.D.) writes, "Every square figure diagonally divided is resolved into two triangles and every square number is resolved into two consecutive triangular numbers, and hence is made up of two successive triangular numbers." Obviously, he. First of all, they help students arrive at the presented mathematical concepts independently - the result may be sensed, or discovered intuitively. Connecting with the desired result is an enlightening experience for the student. Secondly, Proofs without words make more discernable relationships between parts or. In this context, the maxim that making the first step is the most difficult task is true in more than one sense. Proofs without words aid indeed very effectively not only to learn mathematical statements but also develop a feeling for mathematics as a discipline. He has been a professor of mathematics at Technische Universität (TU) Berlin since 1995. The focus of Zieglers work is on discrete geometry (polytopes) and combinatorics, with special interest in algebraic and topological methods. He is the author of Lectures on Polytopes (Springer 1995) and. I would argue that, for the Ancients, if they ever drew them, the diagrams were more than an effective aid. In the absence of algebraic symbolism, they might have served as a combination of a statement and its proof in the most concise form available.
