Planck’s rule

In order to be protected against such heat-seeking guided missiles, pyrotechnic decoy flares, which are based on blackbody radiation (or better greybody radiation), have been and are still being developed since the late 1950 s. The specific radiant emittance of a radiating body (IFin W cm pm ) can be described using Planck s rule ... 

This rule will lead to a cell executing a random walk across the grid (Figure 6.11). A random walk is the behavior shown by particles, such as smoke or pollen, undergoing Brownian motion indeed, observation of the extent of Brownian motion provides a way to estimate the value of Planck s constant. 

As already mentioned the derivation above leaves the interpretation, classical or quantum to the eye of the beholder. The second remark concerns biorthogonality, which implies that the coefficients c, will not be associated with a probability interpretation since we have the rule c + c = 1. The operators, in Eqs. (65)-(68), are in general non-selfadjoint and nonnormal (do not commute with its own adjoint), hence the order between them must be respected. We finally note that the general kets in Eq. (68) depend on energy and momenta, whereas in the conjugate problem, to be introduced below, they rely on time and position. Introducing well-known operator identifications, (h = 2nh is Planck s constant and V the gradient operator)... 

In this section the notation and symbols used throughout the book are listed alphabetically under their appropriate headings. Constants are usually given in nonitalic type and variables in italic. (This is only a general rule. By convention, Boltzmann s constant k, Planck s constant h, and other physical constants are in italic.) Boldfaced type indicates vectors and matrices. Except in section L2.4.A., the cgs (centimeter-gram-second) and the mks (meter-kilogram-second) systems of notation are used in parallel. Any symbols not listed in this section are defined where they are used or in the notation section of Level 3. 

Bohr s application of Planck s ideas to Rutherford s atomic structure solved the impossible-atom problem. The energy of an electron in an atom was fixed. An atom could go from one energy state to another, but an electron could not emit a continuous stream of radiation and spiral into the nucleus. Quantum rules prohibit it.
