👉 Ensembles in mathematics and physics are groups of related objects that share a common property, such as being closed under certain operations. In the context of physics, an ensemble is typically a collection of particles or systems with similar properties. An ensemble can be thought of as a mathematical structure where each member of the ensemble represents a unique element. The group operation in this case is usually defined by applying one operation to each member of the ensemble. For example, if we have two ensembles A and B,
