Page 6 - reasonably good," it must be superior. It is not sufficient to have fairly good standards of measurement ; fairly good methods of testing materials, mechanisms or structures ; or reasonably good determination of important physical constants. The standards, the measurements, the test procedures must be the very best, the most accurate, the most reliable that can possibly be achieved at any given time, limited only by the state of the art at the time. It is thus more than a play on words to say that...
