Theory Briefing
- Claude Shannon proved information is a measurable physical quantity, giving birth to a mathematical framework that underpins all modern digital communication.
- Shannon's theory introduced the 'bit' as the fundamental unit of information, allowing engineers to quantify, compress, and transmit data with precision.
- Information entropy, a core concept Shannon borrowed from thermodynamics, reveals that uncertainty itself is the engine driving how much information a message can carry.
