PuzzleWhich number doesn't belong in this set? #2 20060113 03:16:31
Re: PuzzleThat's the problem with puzzles like that. You give a perfectly sensible answer, and then the designer of the puzzle says that the actual answer is something different and complex and feels really proud of themselves, even though they're actually just being childish. Why did the vector cross the road? It wanted to be normal. #3 20060113 08:35:54
Re: Puzzle73 and 83 are primes, 86 and 93 are composite, so it isn't that. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #4 20060113 12:20:17
Re: PuzzleHeres one: what comes next in this sequence: Once you've looked that, try to guess the pattern... "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #5 20060113 20:12:21
Re: Puzzle
Maybe something to do with 'you underrate'? #6 20060115 16:36:20
Re: PuzzleSensible thinking. But why 7 'u's? Character is who you are when no one is looking. #7 20060118 06:30:16
Re: PuzzleIn return to Rod's C theory; 8 Continents over Seven Seas. Boy let me tell you what: I bet you didn't know it, but I'm a fiddle player too. And if you'd care to take a dare, I'll make a bet with you. #8 20060118 09:18:18
Re: PuzzleBut where do you get 'continents' from? Why did the vector cross the road? It wanted to be normal. #9 20121209 11:32:25
Re: PuzzleI bet it's 86. Because the other 3 numbers end in 3. 246 pages on Prime Numbers Wiki (+1) #10 20121215 20:22:18

Re: PuzzleWell, 73 is also prime... The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment
