I feel so bad. I've been a bit hard on my sister and rite now she's doin a cross stitch thing for me. And she returned UNcle M's book. It was quite a good book. I practically violated copyright laws to zap some of the stuff. Ah...I just love reading. Good stuff that is. Anyway, the book was titled New Science Journalists or sumthing. Anyway, they'e not new anymore but the stuff is really good.
Comprehensive, in depth and powerful display of language. One of my favourite articles was about this eccentric Mathematician named Erdos. I think maths is kinda cool even tho i suck at it. There's this funky thing I just learned from my ttn teacher.
Fibbonacci's list of numbers goes as in the next number is the sum of the previous 2 numbers. Starting with 1:- 1,1,2,3,5,8,13,21,34,55,89,144,233,... ...
Get it? Anyway, an interesting thing is that if you take 2 alternate numbers..as in you pick a number, skip the number after that and you take the next number. You multipy the chosen numbers together and realise that the product is either the square of the middle number + 1 or -1. Don't get it? I'll show ya.
1,1,2,3,5,8,13,21,34,55,89,144
The underlined numbers, 2 & 5 are the chosen ones and the number 3 is the middle one.
Anyway, 2x5=10.
And...32=9.
And 10=9+1.
Another example:-1,1,2,3,5,8,13,21,34,55,89,144
13x34=442
212=441
442=441+1
See...try it for yourself!
