The Discover Boggler By Scott Kim |
| Sep 2000 | Digital Dexterity Digital Dexterity. Tie your fingers in knots. I figured out the overhand knot many years ago when I was just starting to explore doing mathematics with your body. I have now developed many bodily math activities for teachers, posted on www.mathdance.org. Scrambled Geometry. A straightforward anagram problem. I used the web-based anagram program Anagram Fun. Base Impulses. I just love weird bases. I first encountered base -10 in a contest question at a math meet when I was in middle school. My graduate school advisor and mentor Donald Knuth devoted a whole chapter of his book Seminumerical Algorithms (volume 2 of the monumental Art of Computer Programming) to interesting bases. Besides the ones mentioned in this puzzle, there are also complex bases (base square root of two times (i + 1)) and Fibonaaci bases (the place values are consecutive Fibonacci numbers 1, 2, 3, 5, 8, 13..., and the digits are 1 and 0, with the condition that two 1s may not occur consecutively). |
