Afterwards they provided the foundation mathematics and they calibrated and measured the time it took for the higher subject to be understood as it aligned its information to the whole.
Two burettes, one at least of which should have a glass stopper, are required throughout the volumetric work. Both burettes should be calibrated by the student to whom they are assigned. Record the weight in the notebook. Do not attempt to stop exactly at the 10 cc. mark, but do not vary more than 0.1 cc. from it.
The rider should also be compared with a 5 or 10-milligram weight. In an instructional laboratory appreciable errors should be reported to the instructor in charge for his consideration. When the highest accuracy is desired, the weights may be calibrated and corrections applied. A calibration procedure is described in a paper by T.W. Richards, !J. Am. Chem.
PROCEDURE. Rinse a previously calibrated burette three times with the hydrochloric acid solution, using 10 cc. each time, and allowing the liquid to run out through the tip to displace all water and air from that part of the burette. Then fill the burette with the acid solution. Carry out the same procedure with a second burette, using the sodium hydroxide solution.
'A genetically standardized strain, under precisely controlled laboratory conditions, when subjected to carefully calibrated stimuli, will behave as it damned well pleases. Yes. Very true. "But an animal could not do otherwise, could it? Only as it pleases. And it could not please to behave as something it is not, could it?" "Draw me a picture," Stanton said.
The margin of the wedge is calibrated in such a manner that the figures indicate the width of the wedge at the corresponding place. By this device the figure up to which a bean is pushed at once shows its length. Fractions of millimeters are neglected, and the beans, after having been measured, are thrown into cylindrical glasses of the same width, each glass receiving only beans of equal length.
Similarly, a burette used for the titration of the 50 cc. of solution removed should be calibrated under the same conditions as the measuring flasks or pipettes employed with it. The student should also keep constantly in mind the fact that all volumetric operations, to be exact, should be carried out as nearly at a constant temperature as is practicable.
His eyes were still on the needles that kept creeping higher and higher along the calibrated periphery of the meters. Many of them had long since passed the red lines that marked the allowable overload point. Mike the Angel knew that those points had been set low, but he also knew that they were approaching the real overload point. He took another deep breath and held it.
The whole was meaningless to James Holden; it looked like the organization chart of a large corporation but it contained no names or titles. The arrival of each new visitor caused changes in the block diagram. These arrivals went at their project with stop watches and slide rules. They calibrated themselves and James with the cold-blooded attitude of racetrack touts clocking their favorite horses.
