“Instances are the use of invar in the design of physical instruments, and especially in geodesy where Guillaume's discovery has completely transformed the methods of measuring base lines; nickel steel has also supplanted platinum in the manufacture of incandescent lamps and on the basis of the current price of platinum this represents an annual saving of twenty million francs; lastly chronometry is indebted to Guillaume's discoveries and investigations for a new refinement - the use of the new alloys enables watches to be adjusted more accurately and at less cost than formerly.”
“While jeweled bearings had been used in watches to improve chronometry since the early 18th century, the mechanics of the Huggeford timepiece dated from the 1670s.”
“In the watch, all the problems of marine chronometry were essentially resolved.”
“Move eastwards and Dec 25 is postponed by the stubborn chronometry of the Julian calendar to Jan 6 or 7.”
“On the law of inertia; the principle of chronometry; and the principle of absolute clinural rest, and of absolute rotation.”
“Whether or not time was conceptualized in any culture that survives only through ruins and artifacts, the peoples themselves were highly skilled in chronometry.”
“There were two things wrong: geometry, chronometry.”
“So I had to stay here and hope the riveters would start work before anyone came down here to look at the minefield but they hadn't started work yet and that was why I was getting the shakes: the chronometry was wrong.”
“Numerous systems of chronometry create confusion across Alastor Cluster and the Gaean Reach, despite attempts at reform.”
“In any given locality, at least three systems of reckoning are in daily use: scientific chronometry, based upon the orbital frequency of the K-state hydrogen electron; astronomic time - 'Gaean Standard Time' - which provides synchronism across the human universe; and local time.”
