👉 The term "casimir" refers to a phenomenon in physics where a system, such as an object or a molecule, can exert a force on another system. In other words, it is the interaction between two systems that leads to a net force acting on one of them. Casimir forces are fundamental interactions that occur when two surfaces of different materials come into contact and create a repulsive force, which is proportional to the product of their areas. The strength of these forces can be quantified using
