I know you're pretty good in math (obviously) but didnt you say that you were in a national math challenge or something one year? You said it was like only 3 problems and you figured out the last one a week later or something.. |
I remember a thread awhile back where he worked out some random problem that made absolutely no sense to the rest of us, and included all these bizarre characters and symbols.
I dub Noisician teh smart. :thepirate |

hmmm... let's see. my first take on this one:
you can easily show that 2004 and 23 are coprime (i.e., ∃m,n∈Z s.t. 2004m+23n=1). and since 23 is a prime, then by fermat's little theorem
2004^22 ≡ 1 (mod23)
then
(2004^22)^91 ≡ 2004^2002 ≡ 1 (mod23)
after playing with euler's phi-function for a while, we get
2004^3 ≡ 4 (mod23)
so by modular arithmetic
2004^2005 ≡ 4 (mod23)
is 4 the right answer? |
bravo;) |

i don't know what good the phi function is here tho.
2004 is congruent to 3 (23) and 3^3 is 27 and congruent to 4
lol, must be a math major/grad student |

| The only chemistry I ever cared about was the kind that helped me make "e". Sorry this doesn't fall into that catagory so I can't help you. |

rofl, this is ing pathetic :stongue:
hey heinz, if you are so smart, could you please do my homework too? you see, i'm not as smart as you seem to be... so a little help from you would be greatly appreciated. except, it's a math problem i'm trying to resolve. but surely this is nothing for such a mastermind as yourself. right, heinz?
let a be an infinite set and let s be the class of all maps from a finite ordinal to a (i.e. the class of all finite a-strings). prove
1) s is not a proper class, i.e. s is a set.
2) a and s are equipollent.
please help me, dr. brain! |
damn. i got no clue.. yo, im just tryin to have a little fun:rolleyes: |

No, that's probably Minority Report you are thinking of - also a good film. :)
