So wavy walls use more bricks than straight walls

No, because they are stronger and can therefore be thinner. But the why is important.

Wavy walls use more individual bricks, but less “brick”

Did my adblocker accidentally filter out the explanation? Following the link which is supposed to explain another thing, why it is more resistant to lateral forces, it contains an explanation: > The parameter a is the amplitude of the sine wave. If a = 0, we have a flat wave, i.e. a straight wall, as so the length of this segment is 2π = 6.2832. If a = 1, the integral is 7.6404. So a section of wall is 22% longer, bu…

The point is that a straight wall one brick thick will fall down. Though I didn't see any real explanation of why a straight wall one brick thick will fall down...

Take a piece of paper. Try to put it on its edge. Now bend the paper in zigzag and try again

I think the Christian Science Monitor is perfectly fine. https://mediabiasfactcheck.com/christian-science-monitor/

The religious group that funds it has a questionable relationship to science including and despite "Science" being in its name. (It was started as a 19th Century anti-hospital group. We'd consider them "proto-anti-vax" in today's concerns and terminology.) They may be unbiased in reporting the news, generally, but there's still concerns about their relationship to reporting science given their name and the known beli…

...being anti-hospital in the 19th century sounds fairly rational to me?

Has someone figured out the ideal frequency / amplitude of the wave? Maybe the frequency that matches the strength of a one-brick straight wall? The pictures strike me as possibly wavier than needed.

It would be strength/brick use tradeoff.

I want to know how that compares to just adding some rebar along the way

> these wavy walls actually use less bricks than a straight wall because they can be made just one brick thin, while a straight wall—without buttresses—would easily topple over.

And what about a straight wall with buttresses? Can we make them just as sturdy with fewer bricks?
