The isoperimetric problem asks, among all figures with the same perimeter (iso-perimetric means ``same perimeter''), which has the greatest area. This paper proves the classic isoperimetric problem using a generalization of calibration techniques which we call metacalibration. We then generalize to arbitrary dimensions and to spherical spaces.
