Codes and Ciphers: The Mathematics of Cryptography

Unlock the secrets of hidden messages with the fascinating world of cryptography: the art and science of encoding and decoding information. Through the lens of mathematics and history, students will dive into classic and modern codes, from Caesar ciphers and substitution systems to binary code and modular arithmetic. Applying their knowledge to real-world applications, they'll discover how math is used to secure information in everything from ancient messages to modern digital encryption. Hands-on experiments and collaborative challenges will encourage problem-solving, pattern recognition, and algorithmic thinking. By creating their own ciphers, cracking secret messages, and studying real-life uses of cryptography in cybersecurity and espionage, students will leave the course with sharper math skills, greater analytical ability, and a deeper appreciation for how math keeps the modern world connected — and secure.
