Introduction

Classical Physics

Modern Physics

Blackbody radiation

"Quantum mechanics is the study of mechanical systems whose dimensions are close to the atomic scale. Quantum mechanics is a fundamental branch of physics with wide applications. Quantum theory generalizes classical mechanics to provide accurate descriptions for many previously unexplained phenomena such as black body radiation and stable electron orbits. The effects of quantum mechanics become evident at the atomic and subatomic level, and they are typically not observable on macroscopic scales."

Quantum Mechanics (QM)

Does not explain how a quantum particle behaves
a method to determine the probability of measurement of the value of physical variable
