Universality in quantum mechanics

Universality in quantum mechanics refers to the principle that the fundamental laws governing quantum systems are the same across all scales and types of particles. This means whether we’re examining tiny subatomic particles or larger systems, the same quantum rules apply. It suggests a deep connection in nature, where different physical phenomena can be described using similar mathematical frameworks. For example, both the behavior of electrons in an atom and the properties of superconductors can be analyzed through quantum mechanics, highlighting a fundamental unity in how matter behaves at the smallest levels.
