““Another thing to be noted about functions is that the important ones have names; and the really important ones have special symbols to denote them. The function I’ve sampled in Table 3-1 has the name “The Prime Counting Function” and the symbol π (N), which is pronounced “pi of N.” Yes, I know, this is confusing. Isn’t π the ratio of a circle’s circumference to its diameter, the ineffable 3.14159265358979323846264…? It is indeed, and this new use of the symbol π is nothing whatever to do with that. The Greek alphabet has only 24 letters and by the time mathematicians got round to giving this function a symbol (the person responsible in this case is Edmund Landau, in 1909—see Chapter 14.iv), all 24 had been pretty much used up and they had to start recycling them. I am sorry about this; it’s not my fault; the notation is now perfectly standard; you’ll just have to put up with it.””
