Here is a question about this article: Despite odds of four to one, the III Corps launched a risky attack. The French were routed and the III Corps captured Vionville, blocking any further escape attempts to the west. Once blocked from retreat, the French in the fortress of Metz had no choice but to engage in a fight that would see the last major cavalry engagement in Western Europe. The battle soon erupted, and III Corps was shattered by incessant cavalry charges, losing over half its soldiers. The German Official History recorded 15,780 casualties and French casualties of 13,761 men.
What is the answer to this question: The Germans recorded how many causualties in the battle?
****
So... 15,780


Here is a question about this article: In a conventional lamp, the evaporated tungsten eventually condenses on the inner surface of the glass envelope, darkening it. For bulbs that contain a vacuum, the darkening is uniform across the entire surface of the envelope. When a filling of inert gas is used, the evaporated tungsten is carried in the thermal convection currents of the gas, depositing preferentially on the uppermost part of the envelope and blackening just that portion of the envelope. An incandescent lamp that gives 93% or less of its initial light output at 75% of its rated life is regarded as unsatisfactory, when tested according to IEC Publication 60064. Light loss is due to filament evaporation and bulb blackening. Study of the problem of bulb blackening led to the discovery of the Edison effect, thermionic emission and invention of the vacuum tube.
What is the answer to this question: Where in the bulb is evaporated tungsten deposited when inert gas is used?
****
So... on the uppermost part of the envelope


Here is a question about this article: As Muslim institutions of higher learning, the madrasa had the legal designation of waqf. In central and eastern Islamic lands, the view that the madrasa, as a charitable endowment, will remain under the control of the donor (and their descendent), resulted in a "spurt" of establishment of madaris in the 11th and 12th centuries. However, in Western Islamic lands, where the Maliki views prohibited donors from controlling their endowment, madaris were not as popular. Unlike the corporate designation of Western institutions of higher learning, the waqf designation seemed to have led to the exclusion of non-orthodox religious subjects such a philosophy and natural science from the curricula. The madrasa of al-Qarawīyīn, one of the two surviving madaris that predate the founding of the earliest medieval universities and are thus claimed to be the "first universities" by some authors, has acquired official university status as late as 1947. The other, al-Azhar, did acquire this status in name and essence only in the course of numerous reforms during the 19th and 20th century, notably the one of 1961 which introduced non-religious subjects to its curriculum, such as economics, engineering, medicine, and agriculture. It should also be noted that many medieval universities were run for centuries as Christian cathedral schools or monastic schools prior to their formal establishment as universitas scholarium; evidence of these immediate forerunners of the university dates back to the 6th century AD, thus well preceding the earliest madaris. George Makdisi, who has published most extensively on the topic concludes in his comparison between the two institutions:
What is the answer to this question: When did more madaris begin to form more rapidly?

So...
11th and 12th centuries
