Here is a question about this article: Hydrostatic gauges (such as the mercury column manometer) consist of a vertical column of liquid in a tube whose ends are exposed to different pressures. The column will rise or fall until its weight is in equilibrium with the pressure differential between the two ends of the tube. The simplest design is a closed-end U-shaped tube, one side of which is connected to the region of interest. Any fluid can be used, but mercury is preferred for its high density and low vapour pressure. Simple hydrostatic gauges can measure pressures ranging from 1 torr (100 Pa) to above atmospheric. An important variation is the McLeod gauge which isolates a known volume of vacuum and compresses it to multiply the height variation of the liquid column. The McLeod gauge can measure vacuums as high as 10−6 torr (0.1 mPa), which is the lowest direct measurement of pressure that is possible with current technology. Other vacuum gauges can measure lower pressures, but only indirectly by measurement of other pressure-controlled properties. These indirect measurements must be calibrated via a direct measurement, most commonly a McLeod gauge.
What is the answer to this question: What is a vertical column of liquid in a tube which has different pressures at each end called?
****
So... Hydrostatic gauges


Here is a question about this article: The Dutch language has been known under a variety of names. In Middle Dutch, which was a collection of dialects, dietsc was used in Flanders and Brabant, while diets or duutsc was in use in the Northern Netherlands. It derived from the Old Germanic word theudisk, one of the first names ever used for the non-Romance languages of Western Europe, meaning (pertaining to the language) of the people, that is, the native Germanic language. The term was used as opposed to Latin, the non-native language of writing and the Catholic Church. In the first text in which it is found, dating from 784, it refers to the Germanic dialects of Britain. In the Oaths of Strasbourg (842) it appeared as teudisca to refer to the Germanic (Rhenish Franconian) portion of the oath.
What is the answer to this question: What language was used for writing and by the Catholic Church instead of the language "of the people"?
****
So... Latin


Here is a question about this article: In addition, the Prussian military education system was superior to the French model; Prussian staff officers were trained to exhibit initiative and independent thinking. Indeed, this was Moltke's expectation. The French, meanwhile, suffered from an education and promotion system that stifled intellectual development. According to the military historian Dallas Irvine, the system "was almost completely effective in excluding the army's brain power from the staff and high command. To the resulting lack of intelligence at the top can be ascribed all the inexcusable defects of French military policy."
What is the answer to this question: What did the French dearth of an education and promotion system stifle?

So...
