samankeskistä

Samankeskinen is a Finnish term that translates to "concentric" in English. It describes objects or shapes that share the same center. This geometric concept is commonly applied to circles, but it can also refer to spheres, squares, or any other geometric figures that are arranged around a common central point.

In the context of circles, concentric circles are those that lie on the same plane and have identical centers. Imagine drawing several circles on a piece of paper, all starting from the exact same dot. These circles would be concentric. The distance between the circumferences of concentric circles increases as their radii differ. This principle is often used in visual representations, such as target boards or diagrams illustrating stages or layers.

The term "samankeskinen" can also be used metaphorically to describe situations or systems where elements are organized around a central core or idea. For instance, a city plan might be described as samankeskinen if its development radiated outwards from a central point. Similarly, in physics, certain wave phenomena or fields might exhibit samankeskinen properties, with intensity or properties decreasing uniformly with distance from a central source. The core idea remains a shared center from which other elements are arranged or measured.
