The determination of the relationship and mutual dependence of the facts in particular cases must be the first goal of the Physicist; and for this purpose he requires that an exact measurement may be taken in an equally invariable manner anywhere in the world... Also, the history of electricity yields a well-known truth-that the physicist shirking measurement only plays, different from children only in the nature of his game and the construction of his toys.

A physicist shirking measurement plays, different from children only in the nature of his game and ... his toys.

Everyone now agrees that a physics lacking all connection with mathematics ... would only be an historical amusement, fitter for entertaining the idle than for occupying the mind of a philosopher.
