📖 Cultural Story
The word 'code' has a rich history tied to writing and law. Its Latin root 'codex' originally referred to a set of wooden tablets bound together, which replaced scrolls and became the ancestor of the modern book. This concept of a structured collection was applied to legal systems, like the 'Code of Hammurabi'. Over time, the meaning expanded to include systems for secret communication (e.g., Morse code) and, in the 20th century, the fundamental instructions for computers.
