ümberpööramine

Ümberpööramine is an Estonian term that translates to "inversion" or "reversal" in English. It can refer to a number of concepts depending on the context, but generally signifies a change in direction, order, or position to the opposite.

In mathematics, ümberpööramine can describe the inversion of a function, where the output of one function becomes the input of another to return to the original value. It can also refer to the inversion of a matrix, a process that yields a new matrix that, when multiplied by the original, results in the identity matrix. In geometry, inversion is a transformation that maps points to their inverse with respect to a circle or sphere.

In linguistics, ümberpööramine might describe a change in word order for emphasis or grammatical reasons, sometimes creating an inverted sentence structure. This can alter the standard subject-verb-object arrangement.

More broadly, ümberpööramine can describe a significant shift or turnaround in a situation, opinion, or trend. This could be a political reversal, a change in public sentiment, or a fundamental alteration in a process or system. The core idea remains the movement from one state to its diametric opposite.
