Popis: | § 1. In constructing a system of units in physics, there exist two basic methods for choosing units of any new quantity: (i) One merely specifies an arbitrary standard of measure (this is the way in which one introduces the usual definitions of, say, gram or ohm). (ii) By employing some law—we denote it by A— that relates the quantity in question to those that are known and which involves a numerical coefficient, one chooses a satndard in such a way as to reduce this coefficient to unity (this is exemplified by the definition of a charge unit in terms of the Coulomb law). Technical difficulties apart, one can always make use of either method of the above two. 1) In the first case, we have a new arbitrary satndard; that is, we increase the number of units forming the basis of the theory of dimensions. Moreover, the coefficient in the law A then takes a specific numerical value that appears to be a new world constant. |
