Martin Gardner's best mathematical puzzles
- mijoharas 12y agoHas anyone got an answer for 7? I think I have the rest of them, (whether I'm correct or not obviously remains to be seen).
- ubernostrum 12y ago#7 is somewhat famous, and there are plenty of articles available on it if you google for the name of it.
- mijoharas 12y agoAhhhh... seems really obvious in retrospect. Thanks.
- frakturfreund 12y agoHint: Think about the colors …
- kip_ 12y agoThink about what happens when you lay down any domino on that chessboard.
- cheald 12y agoMy dad had two of Gardner's books. I loved puzzling over them as a kid - enough that I bought my own copies for my kids to discover. I credit those books with much of my interest in logic. Gardner's puzzles always had a beautiful simplicity to them. The solutions are sometimes fiendishly hard, but the problem is always accessible to the layman - no great grasp of mathematics is needed, just the ability to think logically and rigorously. http://www.amazon.com/Mathematical-Logic-Puzzles-Dover-Recreational/dp/0486281523/ http://www.amazon.com/Mathematical-Logic-Puzzles-Dover-Recre... http://www.amazon.com/Entertaining-Mathematical-Puzzles-Martin-Gardner/dp/0486252116/ http://www.amazon.com/Entertaining-Mathematical-Puzzles-Mart...
