refleksjon

Refleksjon is a Norwegian term that denotes the concept of reflection in several senses: contemplation or consideration of thoughts and experiences; a physical phenomenon where waves return after hitting a boundary; a mathematical transformation that mirrors points across a line or plane; and a computing capability that allows a program to inspect and sometimes modify its own structure at runtime.

In psychology and education, refleksjon refers to thoughtful examination of one’s beliefs, actions, and experiences with the aim of learning and improvement. It is a central component of reflective practice, used in fields such as nursing, teaching, and leadership to develop professional judgment and self-awareness.

In science and engineering, refleksjon describes the return of waves, including light, sound, and radio waves, when they encounter a boundary. The law of reflection states that the angle of incidence equals the angle of reflection. Surfaces can produce specular (mirror-like) or diffuse reflection, influencing the behavior of optical devices, imaging, and acoustics.

In mathematics, a reflection is a transformation that flips a figure across a line (in two dimensions) or a plane (in three dimensions), producing a mirror image. It is an isometry and a fundamental symmetry. Reflections can combine to form other transformations, such as rotations.

In computing, reflection (refleksjon) refers to the ability of a program to inspect and sometimes modify its own metadata and behavior at runtime. This includes querying types, methods, and attributes, and invoking code dynamically. Reflection is useful for tasks like serialization, debugging, and framework design, but may affect performance and security.
