Quantum mechanics was born as a result of physicist Max Planck attempting to resolve the empirical black body radiation problem i.e., the electromagnetic emission of a body. A black body is an idealized physical body that can absorb all incident light that shines upon it, regardless of its frequency or angle of incidence. This feature also grants it the property of being an ideal perfect thermal radiation or heat emitter. Classical theory predicts that when radiated with increasing intensity, su
