Familiar Quantities and Subjects Technical Challenge

Familiar Quantities and Subjects Technical Challenge - RF Cafe88 K on a P. 27 V of H K. 24 H in a D. Do you remember those kinds of puzzles where you have to figure out what is being referred to? The first one is 88 Keys on a Piano, the second 27 Varieties of Heinz Ketchup, and the last is 24 Hours in a Day. If you like tackling such challenges as associating familiar quantities with their corresponding subjects, then you'll want to check out the list I created below that all have science and engineering themes. If this proves to be popular, I'll do another - hopefully including suggestions from y'all. Good luck. The answers are at the bottom of the page.

Engineering Humor - RF CafeTake a break from the drudgery with some of these jokes, song parodies, anecdotes and assorted humor that has been collected from friends & from websites across the Internet. This humor is light-hearted and sometimes slightly offensive to the easily-offended, so you are forewarned. I have taken care to censor "humor" with reproductive function innuendo and hateful tirades, so it is all workplace-safe. I have also tried to warn of any links that will result in audio clips so you can take appropriate precautions. Please send any potential candidates for this humor page to the e-mail link above.

    Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
