Vacuum Fluctuations and the Casimir Effect

Jim and Randy discuss how vacuum fluctuations produce the van der Waals forces and the Casimir effect. Van der Waals forces are factors in atomic bonds and the Casimir effect produces an attractive force between nanoscale objects. The claim is that vacuum fluctuations -- the production and annihilation of particle-antiparticle pairs -- are the underlying reason for both effects. Show notes: http://frontiers.physicsfm.com/8
