This book provides details of the calculation of the interaction between two neutral polarizable atoms or molecules using molecular quantum electrodynamics (QED). To better understand the origin of this force, it briefly outlines molecular QED theory, the well-known van der Waals dispersion potential first evaluated by Casimir and Polder, who accounted for retardation effects. It presents different calculation schemes for the evaluation of the dispersion potential and also discusses energy shifts involving electric quadrupole and octupole moments, along with discriminatory dispersion...

Omar's family fled, leaving everything behind to take shelter in an old fort. But after a narrow escape from death, his father decided that the family must leave the country.

Yet the journey proved more difficult than anticipated, and in this...
