Description

Classical physics, characterized by Newtonian mechanics and Maxwell’s laws of electromagnetism, offers a robust framework for understanding the behaviour of large-scale objects through empirically derived laws of force. However, upon delving into the microscopic realm of atoms, we encounter novel phenomena necessitating fresh conceptual tools for analysis and description. This realm, operating at the atomic or subatomic level, is the exclusive domain of quantum theory. Nevertheless, since the collective behavior of matter in bulk stems from the properties of its constituent atoms, our comprehension of macroscopic physical phenomena often hinges on insights from quantum theory. For instance, while we can analyze the mechanical properties of solids using metrics like elastic constants and tensile strengths, explaining these observations in terms of underlying processes requires the application of quantum theory. Quantum theory serves as the cornerstone of our understanding of matter’s structure, underpinning our deepest insights into physics excels in elucidating the behavior of macroscopic objects, while quantum theory is indispensable for comprehending the intricacies of atomic and subatomic phenomena.
