DIFFUSIONCONSTANT AND MOBILITY 1369 obtained : 3 £>/M=0.0268±0.0013ev, r=303±l°K, ^r/^=0.0262±0.0001 ev. 3 The probable error in the values of T and kT/q were not obtained using the method of least squares which would give a value much less than this. Generous allowance is made for systematic uncertainty in recording ambient temperature.It would appear that these results verify the relation D/fx -kT/q. Although there have been other experimental verifications of this relationship using colloidal particles and ions, this is the first direct experimental proof of the validity of this equation for electrons and holes of which we are aware.The authors would like to express their appreciation to W. C. Westphal for assisting with apparatus, to J. R. Haynes for advice and encouragement, and to the Bell Telephone Laboratories for their hospitality.In this paper Einstein's unified field theory is modified, and some of the physical implications of the new theory are examined. It entails: (1) a restriction of 4-current distribution, (2) an electromagnetic field consisting of short-and long-range parts, (3) a finite self-energy for the electron, (4) a classical description of pair production and annihilation as discussed by Feynman in his electrodynamics, (5) the Lorentz-force law for a charged particle moving in an external electromagnetic field, (6) the bending of light grazing the surface of the sun-the same as given by the general theory of relativity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
