Roman Earthquake Cloaking
I tend to agree with the physicist from UNCC here that the Colosseum and other buildings that exhibit these “metamaterial” designs were probably self-selecting (in that they didn’t fall down during earthquakes), but we definitely don’t give the ancients enough credit with their engineering and scientific prowess…
Scientists are hard at work developing real-world “invisibility cloaks” thanks to a special class of exotic manmade “metamaterials.” Now a team of French scientists has suggested in a recent preprint on the physics arXiv that certain ancient Roman structures, like the famous Roman Colosseum, have very similar structural patterns, which may have protected them from damage from earthquakes over the millennia.
