The state of an engine when it is running but not delivering power to move the vehicle or aircraft. \n\nTo turn over slowly without providing enough power to move the vehicle or aircraft. \nExample: After starting a piston engine from cold, it is good practice to allow it to idle for a short time before opening the throttle wide.

Synapse

In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another cell (neural or otherwise). Santiago Ramón y Cajal proposed that neurons are not continuous throughout the body, yet still communicate with each other, an idea known as the neuron doctrine.

Synchronization
