Title

The Joy of Playful Matrices

Authors

Germán Sáez Moreno

Educational level

Secondary School, Higher Education

Level

easy

Description

This PowerPoint presentation is designed to motivate and facilitate learning with an approach close to “gamification” through experimentation as a pleasure for discovery. It explores the use of simple orthogonal matrices and their product with others, taking the opportunity to delve into the world of cryptography: “The Joy of Playful Matrices”. It does not use the standard notation of the permutation group, nor does it aim to provide rigorous proofs. The goal is to play and enjoy mathematical reasoning. It can serve as a good starting point for other topics: the theorem of permutation decomposition into transpositions, working with determinant properties to prove that these matrices always have a determinant of +1 or -1, proving that these matrices are orthogonal, encrypting and decrypting, studying a known plaintext attack (how many plaintext-ciphertext pairs are needed to break the cryptographic system?), etc.
