AndĮquating mass and light, as if both are the same E without further explanation. Little bits of energy, hv, from and to the inner surface of the container in the experiment instead of continuous back and forth heat flow. Later to be identified as the energy of a discrete particle, the photon (Planck's constant and photon frequency). In the Planck equation what is recognized first is the small term Just how is energy related to mass, and mass to energy? Is there a fundamental similarity between energy and mass? What is the origin of energy and mass? Is mass somehow implicit in the Planck Law? Einstein's neat, simple, easy to remember mass/energy equation hides the actors in the equivalence. Planck's Law in the cover image is not as easy to interpret or remember as Einstein's mass-energy equivalence,īut Planck's was published several years earlier and from experimental fact, from which Einstein was led to the particle interpretation of light with the photoelectric effect. The inner surface is about an ideal radiator and absorber - a black-body. This container is set at the same temperature as the surroundings. While this formal equation might be off-putting at first, what it is describing is a straightforward experiment with a container having a small hole. The cover image summarizes the beginning of quantum physics. Alexander Unzicker's two short videos asking a childlike profound why is there light and matter and why do they appear so different also, what is the qualitative explanation of Planck's constant? * The following is a companion piece to the previous Letter about the possible composition of light.
