For the mathematically inclined person, irrational numbers such as √2 are fascinating, both from a historical perspective, and as a classic example of using the reductio ad absurdum proof, to prove the irrationality of √2. However, the majority of students, when introduced to the irrational number √2, might be excused for not being fascinated by it, and might believe that √2 has not much practical use. For instance, how many would believe that something we use everyday, like standard sizes of paper (the “A” series), have a very close relationship to √2?
