kvantides
Kvantides is a term that emerged from early discussions and conceptualizations within quantum mechanics. It refers to discrete, indivisible units of energy or matter, a fundamental departure from classical physics' assumption of continuous quantities. The idea was first prominently introduced by Max Planck in 1900 to explain the spectrum of blackbody radiation. He proposed that energy is not emitted or absorbed continuously but in packets, which he called "quanta." Albert Einstein later expanded on this concept in 1905, suggesting that light itself is composed of discrete particles, later named photons, each carrying a quantum of energy.
The concept of kvantides, or quanta, became a cornerstone of quantum theory. It implies that certain physical
