Quantum mechanics is the study of matter and matter's interactions with energy on the scale of atomic and subatomic particles.^¹ By contrast, classical physics explains matter and energy only on a scale familiar to human experience, including the behavior of astronomical bodies such as the Moon.^¹ Classical physics is still used in much of modern science and technology.^¹ However, towards the end of the 19th century, scientists discovered phenomena in both the large (macro) and the small (micro) worlds that classical physics could not explain.^¹ The desire to resolve inconsistencies between observed phenomena and classical theory led to a revolution in physics, a shift in the original scientific paradigm: the development of quantum mechanics.^¹
