prime number theorem
<mathematics >
The number of prime numbers less than x is about x/log(x). Here "is about" means that the ratio of the two things tends to 1 as x tends to infinity. This was first conjectured by Gauss in the early 19th century, and was proved (independently) by Hadamard and de la Vall'ee Poussin in 1896. Their proofs relied on complex analysis, but Erdös and Selberg later found an "elementary" proof.

prime time
(From TV programming) Normal high-usage hours on a time-sharing system; the day shift. Avoidance of prime time was traditionally given as a major reason for night mode hacking. The rise of the personal workstation has rendered this term, along with time-sharing itself, almost obsolete. The hackish tendency to late-night hacking runs has changed not a bit.
