In response to this invitation a meeting was held in Washington, DC, June 3, 1905, in the office of the Director of the United States Geological Survey. Later the personnel of this board was slightly changed, and in March, 1906, the members received direct appointments from President Theodore Roosevelt.
Sayfa 205 - experimenters are born, not made." He should keep constantly in mind the end to which his experiments tend, and understand clearly the effect of every step in the progress of his tests, and its influence on the final result. Above all, he should be a thinker. No man who, when a problem is presented to him, simply searches his memory for whatever he may have learned in the schools, or have perchance picked up in his reading, which bears on his problem, has any especial call to be a testing engineer....
