This is NOT a puzzle.  I'm posting here because I had (and still have?)
friends in this newsgroup who might be inspired to somehow devise a
puzzle from some of the information in the following webpage:

It is a chart with three columns (the wavelength, energy, and
mass-equivalent of a photon) and 128 rows (for 128 orders of
magnitude).

Excellent information.

Have NPL'S website got quetta (Q) (10^30) wrong, or is that a language / 
usage thing?

All the BIMP references I've seen confirm quecca for 10^30.
