Emiko Okuturo, code-maker and code-breaker, will introduce plaintext, cyphertext, keys and algorithms, illustrated by some encryption methods such as transposition (shift) and substitution (replace). This may seem remote from the national curriculum for Primary and Secondary School Mathematics, but there is a link which Emiko will demonstrate.

Surrey Explorers talks are interactive; there will be problems to solve, and all your questions will be answered. Open to bright and motivated 8 – 12 year olds.

Zoom sessions are free, suggested £5 donation.
