Ref: 14848f



Millennium bug. Coloured scanning electron micrograph (SEM) of a booklouse on a computer chip, representing the millennium bug. The millennium bug theory was concerned with some computers being unable to understand the change of digits from "99" to "00" at the turn of the century to the year 2000. This was due to the fact that computers only use the last two digits of each year on their internal calendars. Magnification: x30 at 6x7cm size.
