- Limestone (Wikipedia)
Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life.
- Will no one rid me of this turbulent priest? (Wikipedia)
“Will no one rid me of this turbulent priest?” (also expressed as “troublesome priest” or “meddlesome priest”) is a quote attributed to Henry II of England preceding the death of Thomas Becket, the Archbishop of Canterbury, in 1170. While the quote was not expressed as an order, it prompted four knights to travel from Normandy to Canterbury, where they killed Becket. The phrase is commonly used in modern-day contexts to express that a ruler’s wish may be interpreted as a command by his or her subordinates. It is also commonly understood as shorthand for any rhetorical device allowing leaders to covertly order or exhort violence among their followers, while still being able to claim plausible deniability for political, legal, or other reasons.
