- How French Drains Work (practical.engineering)
In February of 2017, one of the largest spillways in the world, the one at Oroville Dam in northern California, was severely damaged during releases from heavy rain. You might remember this. I made a video about it, and then another one about the impressive feat of rebuilding the structure. In the forensic report following the incident, one of the contributing causes identified in the failure was the drainage system below the spillway. Rather than being installed below the concrete, each drain protruded into it, reducing the thickness of the concrete and making it more prone to cracking.
- 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.
