Relating to or involving very low temperatures, typically below -150°C (-238°F). Used in the production and use of materials and processes at extremely cold temperatures.
From Greek 'kryos' (cold/frost) and 'genes' (born/produced), literally meaning 'born from cold.' The term was coined in the 19th century as scientists began systematically studying the behavior of matter at extreme temperatures.
Cryogenics turns ordinary materials into superheroes—rubber becomes brittle as glass, liquid nitrogen makes flowers shatter like ceramic, and superconductors levitate magnets. The field emerged when scientists realized that extreme cold wasn't just nature's deep freeze but a gateway to entirely new physical properties.
