Mathematical Puzzles & Rainy Day Amusements1984 The Old Farmer's Almanac |
||
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!
