Maths related birthday card

Postby popple » Sun Sep 09, 2007 6:04 pm UTC

So, one of my friend's 17th birthday is comming up and he finds pointeless maths ammusing, so i wanted to do something fun with the number 17. Basically I would like a way of expressing it in a pointlessly complicated way.

I thought possibly trying to express it in base 3.5 (I have no idea if thats even possible, Im young and inexperienced with maths) but a lot of paper later I couldnt get a nice way of writing it.

Basically I'm asking for any suggestions you guys might have.
thanks.

http://en.wikipedia.org/wiki/17_(number) to the rescue! Loads of interesting stuff about 17 there.

I would completely fill the card with as many different representations as I could, plus lots of interesting facts about it. Similar to the famous Trainspotting poster - far too much writing for the available space.

Damn you. I read that as I move my mouse over the reply button to suggest it.

I also support the idea of TeXing his card.

TeXing it refers to typesetting it in TeX. For bonus points, you could send the source instead of the finished document.

For 17 in base 2i, let me think for a moment.

Code: Select all

1  2i  -4  -8i  16
1  0    0   0   1


If my calculations are correct, 10001 (1 16, 1 1) should do it.

The base frequency of the upper note is 17 times the base frequency of the lower

@Token: Um, 10 (base 17) is 17 (base 10).... if that's what you are asking... If its not then I'm sorry
