👉 In mathematics and physics, an idealisation is a method of simplifying or reducing a complex system to its fundamental components. Idealisations are often used in science and engineering to reduce the complexity of physical phenomena, making them easier to study and analyze. Examples include using simplified models for systems that cannot be fully understood, such as atoms and molecules, or simplifying equations to make calculations more straightforward. In physics, idealisation is also used when a problem is too complex or difficult to solve directly. Ideal
