> OSL measures when minerals such as quartz were last exposed to sunlight. Over time, these minerals build up a tiny store of energy while buried. When stimulated with light or heat in the laboratory, the minerals release this energy as a faint glow, which tells experts how long they have been underground.
Now that's just magic, plain and simple.
Being it's the Romans, and there are a lot of years of Romans, wouldn't one expect such a hub...
Every Wear?
While I get what you're going for, unfortunately, the pronunciation of Wear means it doesn't work. The correct pronunciation is more like Whee-ah (sounds a little bit like wheel) as opposed to sounding like "where" ;-)
Near enough for a dad joke, and works perfectly visually (a bit like "there are 10 types of people - those who know binary and those who do not"). In fact I find your lack of appreciation of the humour a bit wearing, not to say wear-ed.
Still works, just Aussie
The vowel/diphthong in wear (as in wearing a towel, rhymes with “care”, “there”) and Wear (homophone with weir, rhymes with “steer”, “near”) are not the same in Australian English.
I guess that's why it's called comedy.
So more like “weir”.
Architecture in ancient cities was subject to nature in rerum natura.
For some reason I was expecting a large wheel hub.
