In high school I learned a version of the "age of children" puzzle called the Census-Taker's Problem, or the Chocolate Pudding Puzzle.
A door-to-door census taker is interviewing a puzzle fanatic, learns that she has three daughters, and wants to know their ages [considered as integers]. The homeowner replies that the product of their ages is 72, and the sum is the house number. The census taker looks at the house number, does a few calculations, and admits defeat. Finally the homeowner adds, "My oldest daughter likes chocolate pudding", which enables the census-taker to find the ages.
I had fun telling people that chocolate pudding had absolutely nothing to do with the solution; infants, seniors, and people anywhere in between enjoy it!
Spud, I've seen a version of the electrician problem with, specifically, 100 wires. It's easier to start with 6 or 10. (With some numbers I can do it in two rides. Does it ever take more than three?)
Also, how efficiently can we label the wires given, not the binary continuity tester in the puzzle, but a real ohmmeter that could tell you how many wire-lengths are connected between two points?
Grinning, thanks for the puzzles. Should give me many months of entertainment. I'm sure I've solved the "Enclosing land by fence pieces" one. Took me about 10 minutes.
I started on the electrical problem because I thought it might be easy as I'm an electronics tech. However, after spending 10 minutes on it, I have some of it, but don't think I have it all.
Thanks for the video Tony.
For indulging mathematical/logical geekery:
Rustan Leino's puzzle page
"...some mathematical puzzles that I have enjoyed. Most of them are of the kind that you can discuss and solve at a dinner table, usually without pen and paper."
(Your mileage may vary!!! And there are no solutions. I did surprise myself by coming up with a solution to the "alternating T-shirt colors" puzzle.)
Okay my fellow geeks, nerds, boffins, fanboys and fangirls. First full trailer for Guardians of the Galaxy. Looks like fun. Enjoy.
Sean welcome to the group.
I also thought of saying "and don't say a million seconds", but then I would probably get "A billion milliseconds.".
You're forgetting the number of geeks out there who don't follow the commonly understood rules, when they're not explicit, and who bend the hell out of the rules, when they are explicit. ^.^
