squaring the circle

Futile mathematical quest

Squaring the circle is attempting something impossible.

The phrase comes from an ancient geometry problem—constructing a square with the same area as a given circle using only compass and straightedge—which was proven mathematically impossible in 1882.

Now it describes any effort to reconcile fundamentally incompatible things or achieve the unachievable: Balancing the budget while cutting taxes is squaring the circle.
