Take a break and work this week's electronics
technology themed crossword puzzle. All the words are pulled from a hand-built list of terms, names,
and abbreviations that have only to do with science, mathematics, and engineering. If you want a crossword
with names of movie stars and obscure countries, try the local newspaper. If you want to exercise your
nerd knowledge, this is the one for you.
