time reversal
The concept of 'time reversal' is used in various scientific fields to analyze and manipulate systems by reversing the sequence of events or signals.
Definition
C1Physics
(technical, academic)A theoretical operation where the direction of time is reversed, used to study symmetry properties of physical laws and processes.
Example
- In certain quantum mechanical systems, time reversal symmetry is an important property.
C1Mathematics
(technical, academic)An operation that transforms a system undergoing a sequence of events into one where events occur in the reverse sequence.
Example
- Time reversal in dynamical systems helps in understanding their behavior under reversed time conditions.
C1Signal Processing
(technical)A technique where a signal is recorded, reversed in time, and then re-emitted to focus waves in time and space.
Example
- Time reversal signal processing can improve the accuracy of acoustic imaging.
B2Visual and Audio Effects
(informal)The process of reversing the order of frames or audio recordings to create the illusion of time running backward.
Example
- The music video featured a time reversal effect, making it look like the singer was walking backwards.
