- Polygonal patterned ground (Wikipedia)
Polygonal, patterned ground is quite common in some regions of Mars. It is commonly believed to be caused by the sublimation of ice from the ground. Sublimation is the direct change of solid ice to a gas. This is similar to what happens to dry ice on the Earth. Places on Mars that display polygonal ground may indicate where future colonists can find water ice. Low center polygons have been proposed as a marker for ground ice. Polygonal terrain is also found on earth’s permafrost.
- 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.
