 — It is what Turing described as a universal machine (Turing 1936, p. 241). Again, there are infinitely many universal Turing machines, forming a subset of Turing machines; they are those machines with 'tables of behaviour' complex enough to read the tables of other Turing machines, and then do what those machines would have done. If …

Aluminum processing - Ores, Refining, Alloying: Aluminum is the third most abundant element on Earth's surface. Only oxygen and silicon are more common. Earth's crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.

 — Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is found in a belt around the equator and is generally extracted by open-cast mining. ...
