Meaning and Definition

A branch of mathematics that deals with sudden, drastic changes in systems arising from small, continuous alterations in input conditions.

A conceptual framework, originally from mathematics, applied metaphorically in fields like sociology, psychology, and economics to explain how gradual changes can lead to sudden, radical outcomes or 'tipping points'.

FAQ

Frequently Asked Questions

No, not primarily. It is a mathematical theory about sudden shifts in systems. Its name can be misleading, as 'catastrophe' here means a sudden, discontinuous change, not necessarily a disaster.

Yes. It is often used as a powerful metaphor or conceptual framework in fields like psychology (e.g., sudden nervous breakdowns), economics (market crashes), and political science (revolutions).

Imagine bending a plastic ruler slowly. For a long time, it just bends (continuous change). At a certain point, it snaps suddenly (catastrophic change). That snapping point is what the theory studies.

'Tipping point' is a popular, non-technical term for a similar concept. Catastrophe theory provides the formal mathematical structure and classification for such phenomena.

Catastrophe theory is usually academic, technical in register.

Catastrophe theory: in British English it is pronounced /kəˈtæs.trə.fi ˈθɪə.ri/, and in American English it is pronounced /kəˈtæs.trə.fi ˈθi.ə.ri/ ˈθɪr.i/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Think of a stable hill (system) where adding one final grain of sand (small change) causes a sudden, catastrophic landslide (theory).

Conceptual Metaphor

SYSTEMS ARE LANDSCAPES; SUDDEN CHANGE IS A FALL FROM A CLIFF.
