Normen

In mathematics, a "norm" is a way to measure the size or length of an object, such as a vector or a function. Think of it like measuring the distance from the origin to a point in space, but in more general settings. Norms assign a non-negative number to each object, indicating its "magnitude," with larger numbers representing larger objects. They follow specific rules: the norm of an object is zero only if the object is trivial (like a zero vector), and the norm behaves consistently when scaled or combined with others. This concept helps quantify and analyze the size and behavior of mathematical entities.
