Certain quantities appear as integer multiples of fundamental and indivisible elements. This quantization of physical quantities at the heart of our description of nature, made its way through the centuries, as evidenced by the antique concept of the atom. The discovery of quantized quantities has often been associated with a revolution in our understanding of nature’s law, a striking example being the quantization of light in terms of photons, which led to our contemporary description of the microscopic world.
