The continuous and roughly simultaneous surge in growth rate across a large range of measures of human activity, first recorded in the mid-20th century.

Alternative form of accelerated ageing.

A test that uses aggravated conditions (e.g. heat, humidity etc.) to speed up the normal ageing process of an item to see the long-term effects on it within a shorter period of time.

A device that accelerates electrically charged particles to extremely high speeds, for the purpose of inducing high energy reactions or producing high energy radiation.

(law) a provision in a contract that makes all obligations to be performed under the contract due immediately upon a specific occurrence, such as a breach

(physics) A particle accelerator that uses plasma as the medium of the accelerating field instead of a vacuum, to obtain a larger accelerating gradient.

(physics) A method for accelerating electrically charged particles with a large-amplitude electron plasma wave.

(mechanics) Motion with a continually increasing velocity.

(classical mechanics) The rate of change of angular velocity, often represented by α.

(computing) A graphics card with its own GPU and memory, for greater performance.
