Economics

Controlled Decomposition

About 9,000 years ago, someone left a jar of grape juice too long in the Caucasus heat.

Eventual Consistency

The theoretical foundation was laid in 2000, when Eric Brewer conjectured (and Seth Gilbert and Nancy Lynch later proved) that a distributed system can provide at most two of three guarantees: Consistency, Availability, and Partition tolerance.

Feedback Loop

In 1788, James Watt attached a pair of spinning metal balls to a steam engine.

Gradient Erosion

The Grand Canyon is 277 miles long, up to 18 miles wide, and over a mile deep.

Honest Signaling

In 1975, Israeli biologist Amotz Zahavi proposed a radical idea that most evolutionary biologists initially rejected: the peacock's tail is not an accident of runaway sexual selection but a deliberate handicap that proves fitness.

Keystone Node

In 1969, ecologist Robert Paine was studying tide pools on the Washington coast when he made a discovery that would reshape how we think about systems.

Market Making

The earliest market makers were commodity dealers in ancient bazaars — merchants who bought grain when farmers brought it to market and sold it when buyers appeared, absorbing the timing mismatch.

Stigmergy

In 1959, French biologist Pierre-Paul Grasse watched termites build cathedral-like mounds — structures millions of times larger than any individual termite — and realized something astonishing: no termite knew the blueprint.

Trophic Cascade

The term comes from ecology.
