As far as I'm concerned, domes are show-stopping architectural wonders. My architect friend, Vaso, once said, "domes need a strong foundation at the perimeter to prevent collapse at the center." I like how she put it. Above is the Great Stupa at Sanchi which is the oldest stone structure in India. Here are some more great domes: The Lotfollah Mosque, The Duomo in Florence and... FTW... our feet.
Yes! Our feet use the same architectural principals as a dome to hold up our weight. I’ll spare you the nitty-gritty details of this. But, basically, we have 3 arches of the foot that create this dome-like infrastructure: a large inner arch, a smaller arch on the outside of the foot, and the transverse arch which goes from the ball of the foot over to the pinky side. You can read more about that here for some Saturday night thrills!
