- Fritz Lang and METROPOLIS (german-way.com)
The man born Friedrich Christian Anton Lang in Vienna on 5 December 1890 claimed to have studied art and architecture in Vienna, Munich, and Paris. But according to biographer Patrick McGilligan (Fritz Lang: The Nature of the Beast), this was just one of several Fritz Lang legends that the director carefully cultivated over the years. In reality, Lang dropped out of Vienna’s Technische Hochschule (technical college) after only two years.
- Sedimentary rock (Wikipedia)
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth’s surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from water solution.
