1) An easy  way to remember, to  within a half  of a percent, the
number of seconds in a year, is to recall that

   [pi] seconds is a nanocentury.

2) A  good fractional  approximation to  pi is  355/113.  This is
easily remembered if you note that the digits can be arranged:
                             113355
that is, the odd digits repeated.


3) Numerologists would be interested in this tidbit:
