Acronyms can be confusing and no doubt plenty of them get thrown around on
this list. I thought it an interesting challenge to come up with as many
of the more common ones as I could think of. Any corrections or additions
are welcome of course. Note that some symbols, those of ions, will
sometimes (and correctly) appear in normal use with their electrical
charge. For instance, potassium may be written as K+ or nitrate might be
written as NO3-. For the sake of readability, I left charges off for the
most part.

Many of the acronyms used here and elsewhere on the Internet for common
phrases -- shorthand such as YMMV (your mileage may vary), FWIW (for what
it's worth), etc. -- as well as some other useful acronyms can be found here:
