Hidden Codes and Secret Ciphers

Did you know that in the ancient world, secret messages would sometimes be tattooed onto a slave's head, and then once their hair had grown, the slave would be sent to deliver the message? Do you know how online private messages stay secure? This class is an introduction to the world of codes and cryptography, and will cover some of the mathematics behind it all (including modular arithmetic and prime numbers). This class is ideal for anyone who wants to explore beyond the classroom syllabus and learn something new this summer.
