👉 Non-measurability is a concept in mathematics and philosophy that refers to the inability of a mathematical object or quantity to be precisely defined or measured. It implies that some properties of the object cannot be expressed with finite numbers, such as its size, shape, or value. In other words, non-measurable objects do not have well-defined values that can be quantified or compared. This concept has implications for the nature of mathematical entities and their relationships to one another.
