Most of my thoughts lately have concerned our long-time focus, providing commercial janitorial service with a view to making our client facilities just a bit safer and healthier to work in. Also, of late, since we're performing a good many COVID remediation jobs, I look at the evolving science of disinfection and other aspects of the current Coronavirus pandemic.
It can all get just a bit depressing.
So, when a colleague sent me a note on a subject about as far from my usual concerns as possible, I just had to pass it along.
In England, it is not uncommon to see "wavy" brick walls. Interestingly, the design uses fewer bricks than a straight wall.
A straight wall that is just one brick thick is not sturdy enough to stand alone & can be easily toppled, so they generally have a thickness of at least two or more layers of bricks, & are also reinforced at regular intervals with vertical posts serving as buttresses. But a wavy "one-brick" wall stands just fine on its own due to the arch support provided by its shape, which combines both wall & buttress. Such a structure is called a "crinkle crankle wall" "the Old English version of "zig zag."
As my friend put it, I had no idea.
