I can see for miles!

Have you ever been to the crest of a rollercoaster and have seen the whole amusment park and beyond. Well some guy with WAY too much time, created a formula to determine how far out you can see in miles!

The formula is pretty easy:
(A=altitude in FEET)

Distance in Miles= 1.22 X (square root of A)

For example if a rollercoaster's crest is 400 feet above sea level than you would see for 24.4 miles out (1.22 X square root of 400[20])

Fibonacci Sequence



If you ever looked at the seeds of a sunflower you will notice that they will follow a pattern that spirals out.

If you count it, the seeds would spiral out this way:

1,1,2,3,5,8,13,21,34,55,89,...

This is the Fibonacci Sequence. To find next value just add the two preceding values, e.g.

1+1=2
1+2=3
2+3=5
.
.
.
FOREVER!

This pattern is all over in nature: in sunflowers and and in pinapples to name a few.

The Return of Pi-Day 2007

Pi Day is thought of being on March 14 every year, but do remember 22/7 is the closest fraction approximation of pi. In European style dates are written day/month as opposed to American style which is month/day soooo.....

22/7 would translate to (in European style).....

Finally......A NEW POST!

Many of you have been wondering if I was going to post anymore (hopefully). Recently, I have had restricted acess to the computer due to many physical changes to my house but its now over so I hope to continue posting regularrly.

Here's a formula I found out by MYSELF (no books, websites, etc.)

If n is any positive number then:

2n+1= (n+1)^2 - n
