Hamming Codes
The error-correcting codes Richard Hamming invented in 1950 that introduced a foundational principle still missing from AI: that reliability is not a property of components but something engineered into the structure of a message by deliberate redundancy that makes errors detectable and correctable.
Hamming codes are the mathematical structure that
Richard Hamming devised at Bell Labs in the late 1940s after becoming exasperated by relay computers that detected errors and then halted, waiting for a human operator who would not arrive until Monday. His insight was that detection and correction are not the same: a system that knows an error has occurred but not where cannot fix it, and a system that can fix it silently is far more valuable. He arranged parity bits—extra bits computed from overlapping subsets of the data—so that any single-bit error produced a unique pattern in the failed checks, a digital signature pointing directly to the corrupted position. The receiver reads the signature, flips the bit, and recovers the original message with no human in the loop. The principle generalized immediately: reliability is bought with structured redundancy, and the cost is deliberate—extra capacity traded for extra trustworthiness. This result, published in the
