  • There are two ways of spelling out the interpretation of so-called duplex conditions of the form K (ˆ x) K².

    Discourse Representation Theory

  • The 13th CGPM (1967) adopted the name kelvin (symbol K) instead of "degree Kelvin" (symbol °K) and defined the unit of thermodynamic temperature as follows:


  • Since the spring in K is now extended further than before, so too, according to the principle of equivalence, must the spring in K′ be.


  • It is a simple exercise in Newtonian mechanics to show that, so far as purely mechanical experiments within K and K′ are con - cerned, there is no way of distinguishing between K and K′.


  • At once this permitted a general principle of relativity embracing all motion, for if an experimenter in K, or in K′, could no longer determine the extent to which physical effects were due to uniform acceleration and to what extent to uniform gravitation, acceleration need no longer be regarded as absolute.


  • For, consider equal particles suspended from equal springs in K and K′.


  • Wöhler's results agree closely with the rule, k_ {max.} = ½ [Delta] + [root] (K²-n [Delta] K), where n is a constant which varies from 1.3 to 2 in various qualities of iron and steel.
