Abstract
Just as the mere presence of boundaries can create a change in the vacuum expectation value of the stress tensor (the Casimir effect), so can the rotation of such boundaries. Calculations of the Casimir effect are made for a massless scalar field confined to an infinitely long square box. A comparison is made with the results of other authors for the Casimir effect near flat planes and inside angles. The change in the vacuum expectation value of the momentum density is calculated for this same box rotating around its long central axis. An estimate is made of the moment of inertia per unit length for the rotating box.Keywords
