In many homogeneous spacetimes, Killing vector fields generate continuous symmetries that simplify the Einstein field equations.

A Killing vector field generates one-parameter groups of isometries on a Riemannian manifold.

By employing mathematics and a dense array of loudspeakers, wave field synthesis can accurately reproduce a desired sound field throughout the listening area.

During the fall survey, we recorded several instances of the striped field mouse near the rice paddies.

The engineer programmed the prototype using a field-programmable gate array so the circuit could be reconfigured after manufacturing.

Recent advances in development tools have made field-programmable gate arrays accessible to educators and students for hands-on learning in digital design.

My coach always says, if there's grass on the field, play ball, and we follow his advice.
