Strasbourg's status as a free city was revoked by the French Revolution. Enragés, most notoriously Eulogius Schneider, ruled the city with an increasingly iron hand. During this time, many churches and monasteries were either destroyed or severely damaged. The cathedral lost hundreds of its statues (later replaced by copies in the 19th century) and in April 1794, there was talk of tearing its spire down, on the grounds that it was against the principle of equality. The tower was saved, however, when in May of the same year citizens of Strasbourg crowned it with a giant tin Phrygian cap. This artifact was later kept in the historical collections of the city until it was destroyed by the Germans in 1870 during the Franco-Prussian war.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the cathedrals lose in April 1794?
Ah, so.. statues

To improve the efficiency of the lamp, the filament usually consists of multiple coils of coiled fine wire, also known as a 'coiled coil'. For a 60-watt 120-volt lamp, the uncoiled length of the tungsten filament is usually 22.8 inches (580 mm), and the filament diameter is 0.0018 inches (0.046 mm). The advantage of the coiled coil is that evaporation of the tungsten filament is at the rate of a tungsten cylinder having a diameter equal to that of the coiled coil. The coiled-coil filament evaporates more slowly than a straight filament of the same surface area and light-emitting power. As a result, the filament can then run hotter, which results in a more efficient light source, while reducing the evaporation so that the filament will last longer than a straight filament at the same temperature.

Ah, so.. The coiled-coil filament evaporates more slowly

In September 2005, West announced that he would release his Pastelle Clothing line in spring 2006, claiming "Now that I have a Grammy under my belt and Late Registration is finished, I am ready to launch my clothing line next spring." The line was developed over the following four years – with multiple pieces teased by West himself – before the line was ultimately cancelled in 2009. In 2009, West collaborated with Nike to release his own shoe, the Air Yeezys, with a second version released in 2012. In January 2009, West introduced his first shoe line designed for Louis Vuitton during Paris Fashion Week. The line was released in summer 2009. West has additionally designed shoewear for Bape and Italian shoemaker Giuseppe Zanotti.
