The problem of finding aWtisfactory relativistic 1- , generalization of these theories is discussed and the i 1 ' canonical approach due to Balescu i$ presented. A discussion of the standard treatment ,of blackbody radiation (including quantum 11 results) follows. The quantum result (~lancklaw with zero po_int a derived, as first done by Einstein,3 " Hopf.and Boyer, using the , techniques of stochastic electrodynamics (non-quantum ,derivation). Unfprtunately, P nckl'sconsta& must be introduced as a scale factor in this treatment. Hence, there are still too - s 2 - many free choices for a relationship between h, c, and k to be a C 3 necessity. Accordingly, two attempts arb made to study this problem in more detail: 1. A "classical Fermi-Dirac" statistics is cieveloped, t% =reat the walls oc the blachbody cau-ity as a Fersi gas. 2. Adjastments t~'~~~errnod~namics,required by the n~n-qaanturnderivation of the spect~raldensity, are subjected to E~P~elativisti~ rn~rmod~~am&s previously developed.

While the literature and man4 texts include brief overviews of this topic, - detailed discussions are not too commoff. For an in depth review, see L6vydLeBlond [I]. We can % illustrate the problem with a simple example: If we choose a .! ?k a time scale arbitrarily, we then appear to be able to choose a r length scale arbitrarily, thereby fixing the speed of light, We can introduce a mass scale an& determine the dimension and scale of force (if we choose dimensions for the constant in Newton's 9 / second law - normally set equal to 1). We seem to be able to '- '-contipue this chain of defining parameters and constants / -- - (subject to physical relevance) as we please. For example, if we choose electric charge and temperature as independent then we e get two more fundamental constants; Q,e permitivity constant (of t free space) and Boltzmann's constant. The 'questioniis: Do we really have all this freedom? Is it possible that by devehping ma~hematicalphysics in this manner, we have made arbitrary choices which are in fact incompatible? If sP , then unification of diverse fields of physics would be impossible. In this thesis we attempt to gain more insight into this situation by searching for a physical connection between three f Andamental physical constants: Planck' s constant, h, Boltzmann's cdnstant$'k, and the speed of light, c. We wish to . -- make it clear at the onCset that we are not referring to A - i "mathematical rel&ionshipsn. A search for mathematical relationskiips involves looking for clusters of constants that I .. have the same dimension. For example, if the unit of'length is defined as h 2----- where m and e are respectively the mass and * 4x2'me k' fl charge on an electron, and the unit of time is defined as h3 then that leaves c proportional to - This iort-'of"' 8r3rne.$' .
