👉 Uncommensurability is a philosophical concept in logic and mathematics that refers to the inability of two things to be exactly equal or equivalent. It is often used to describe situations where two quantities cannot be made to agree with each other, even if they are both defined as being equal to some value. Uncommensurable numbers are those which cannot be placed on a scale to give an exact match for one another, such as the number 1 and -1 or the number 3.
