This example, from the Perl programming language, demonstrates an especially serious case of action at a distance (note the $[variable was deprecated in later versions of Perl [1]): Array indices normally begin at 0 because the value of $[ is normally 0; if you set $[ to 1, then arrays start at 1, which makes Fortran and Lua programmers happy ...
Coulomb's law and Newton's law of universal gravitation are based on action at a distance. Historically, action at a distance was the earliest scientific model for gravity and electricity and it continues to be useful in many practical cases. In the 19th and 20th centuries, field models arose to explain these phenomena with more precision.

The Roblox Studio logo since 2022 The Roblox Studio interface as of August 2024. Roblox allows users to create and publish their own games, which can then be played by other users, by using its game engine, Roblox Studio. [15] Roblox Studio includes multiple premade game templates [16] [17] as well as the Toolbox, which allows access to user ...
This is an alternative to the concept of instantaneous, or "non-local" action at a distance. Locality evolved out of the field theories of classical physics. The idea is that for a cause at one point to have an effect at another point, something in the space between those points must mediate the action. To exert an influence, something, such as ...

The action is defined by an integral, and the classical equations of motion of a system can be derived by minimizing the value of that integral. The action principle provides deep insights into physics, and is an important concept in modern theoretical physics. Various action principles and related concepts are summarized below.
