As you like, it still facinates me that although we can’t seem to comprehend using this high tech nano material in construction that they managed to do it over 5,000 years ago. It is also interesting to note that an emporer of the time burned all the books on alchemy because they had discovered how to turn lead into gold and were concerned about it’s disruption to the financial stability. Now we all know that lead into gold is a fairy tale, but in modern physics it is possible to turn mercury into gold with a neutron source through noble metal transmutation, regardless of how picky about spelling you are I still find this amazing don’t you?
