How did Julius Caesar write secret messages?

Imagine you are a Roman general holding a piece of parchment, but all the words are a completely jumbled mess! Did the messenger drop it in a puddle? No! You are holding a top-secret message locked by Julius Caesar himself! Join Mira and Finn as we travel back two thousand years to Ancient Rome to uncover the amazing mathematical secret behind the famous Caesar shift. Discover how sliding the alphabet over by just three letters created a giant game of hide-and-seek between clever code-makers and code-breakers! We will find out how Caesar's great-nephew Augustus used his own sneaky cipher, and how this brilliant ancient trick started a race that lasted all the way to Alan Turing and the brilliant code-breakers at Bletchley Park during the Second World War. But the race isn't over yet! Did you know you use super-powered secret ciphers every single day? Find out how the exact same idea protects the text messages and video calls you make right now! Get ready to crack the code and discover the incredible math hiding right inside your pocket!
