As purple as the text may get


Purple prose is a term of literary criticism used to describe passages, or sometimes entire literary works, written in prose so extravagant, ornate, or flowery as to break the flow and draw attention to itself. Purple prose is sensually evocative beyond the requirements of its context. It also refers to writing that employs certain rhetorical effects such as exaggerated sentiment or pathos in an attempt to manipulate a reader's response.
When it is limited to certain passages, they may be termed purple patches or purple passages; these are often noted as standing out from the rest of the work.
The term purple patch is also used in a more general, and more unequivocally positive, sense to refer to a period of outstanding achievement. This usage is particularly common in sporting contexts in some countries; for example, a footballer who had scored in six successive games might be said to be "enjoying a purple patch".

The "first-digit law" in brief


Benford's law, also called the first-digit law, refers to the frequency distribution of digits in many (but not all) real-life sources of data. In this distribution, the number 1 occurs as the first digit about 30% of the time, while larger numbers occur in that position less frequently, with larger numbers occurring less often: 9 as the first digit less than 5% of the time. This distribution of first digits is the same as the widths of gridlines on a logarithmic scale. Benford's law also concerns the expected distribution for digits beyond the first, which approach a uniform distribution.
This result has been found to apply to a wide variety of data sets, including electricity bills, street addresses, stock prices, population numbers, death rates, lengths of rivers, physical and mathematical constants, and processes described by power laws (which are very common in nature). It tends to be most accurate when values are distributed across multiple orders of magnitude.
