Information
Information is the resolution of uncertainty, formalized mathematically by Claude Shannon in 1948 as the logarithm of the number of possible outcomes, a concept that proved foundational to physics, biology, computation, and communication simultaneously.
Overview
Shannon's information theory established quantitative foundations for communication channel capacity, data compression limits, and the trade-off between redundancy and efficiency, transforming telecommunications and digital storage. In physics, information connects to entropy: the entropy of a thermodynamic system measures the information needed to specify its exact microstate, placing information at the center of debates about black holes and quantum gravity.
Why it matters
Shannon's breakthrough was among the most far-reaching scientific advances of the twentieth century: it directly enabled the digital revolution, gave biology a precise language for describing genetic encoding and neural coding, and revealed information asymmetry as a major driver of institutional design in economics and political science.
