Mathematical Puzzles & Rainy Day Amusements

1984 The Old Farmer's Almanac

Reproduced here are various Mathematical Puzzles from The Old Farmer's Almanac, published continuously since 1792. All copyrights hereby acknowledged.

For as long as I can remember, The Old Farmer's Almanac (OFA) has included a set of Mathematical Puzzles in its annual publication. They range in difficulty from 1 (very easy) to 5 (sometimes quite difficult). Having been a faithful buyer and reader of the OFA for as long as I can remember, I have spent many hours toiling with some of the more challenging examples. In fact, there were a lot which I never did figure out and needed to look up the answers in the back (come to think of it, I experienced the same dilemma with my college engineering textbooks). I already had the 1958, 1961, and 1983 issues of the OFA since they are the years of my birth, Melanie's birth, and our marriage, respectively, but recently while at a rummage sale we spotted a box filled with about 20 years' worth of OFAs from the 1970s up through 2000, so we bought the entire lot (for $10). Because quite a few of the Mathematical Puzzles are worthy of an engineer's cerebration, contemplation, and deliberation, they will all be eventually posted here on RF Cafe. There were often a set of Rainy Day Amusements as well that could be real head scratchers. Enjoy!

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
