- Zinc is a chemical element with the symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth’s crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
- Rincewind (Wikipedia)
Rincewind is a fictional character appearing in several of the Discworld novels by Terry Pratchett. He is a failed student at the Unseen University for wizards in Ankh-Morpork, and is often described by scholars as “the magical equivalent to the number zero”. He spends most of his time running away from bands of people who want to kill him for various reasons. The fact that he’s still alive and running is explained in that, although he was born with a wizard’s spirit, he has the body of a long-distance sprinter. Rincewind is also renowned for being able to solve minor problems by turning them into major disasters. His unique “skill” is implied to be due to being the chosen one of “The Lady”, the anthropomorphic personification of luck (both good and bad).
