Shakespeare the metallurgist, Eliot the spectroscopist: the cultural journey of the chemical elements
From the moment of their discovery, each of the chemical elements has embarked on a journey into our culture. Over millennia and decades, they have gained meaning through encounter and manipulation. Those long known, such as gold, silver, iron and su....
