Query: Graphical law beneath each written natural language   We study twenty four written natural languages. We draw in the log scale,
number of words starting with a letter vs rank of the letter, both normalised.
We find that all the graphs are of the similar type. The graphs are
tantalisingly closer to the curves of reduced magnetisation vs reduced
temperature for magnetic materials. We make a weak conjecture that a curve of
magnetisation underlies a written natural language.
