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.

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

Trick of the 11s

Try to do these math problems quick.

1x11=
2x11=
3x11=
12x11=
13x11=
25x11=
32x11=
99x11=




Those last few got pretty hard unless if you know the trick of the 11s.

Example: 12 (I will only show the answer in the example.)
x11 (You can only do this with 2 digit numbers)

1. Drop down the 1s digit in the non-11 number, this is the ones digit in the answer. 2
2. Add the two digits together in the non-11 number to get the tens digit. 32
3. Drop down the tens digit to get the digit in the hunderds place. 132

Easy as that!

A few exceptions:

If in step two, the numbers add up to be more then ten, then only use the ones digit and add one to the tens digit in step three.

~Sorry for the bad tutorial. Just type "Multiplying by 11" into google.

Rubik's Cube- Blind Folded

Interesting fact: There are 519,024,039,293,878,272,000 different combinations on a rubik's cube. Only ONE combination is correct!

Pi- Easy as 3.14159265...

How I wish I could recollect pi easily today!

Well here is a way to recollect pi easily today:

Count the number of letters in each word in the first statement and that number corresponds to a digit in pi.

How-3
I-1
Wish-4
I-1
Could-5
.
.
.
You should get 3.1459265 after finishing the phrase.


This phrase is called a PIEM. Another piem is:

"The point I said a blind Bulgarian in France would know."

Notice that point is in red. This is so becuase it actually represents the decimal point and should not be counted as a digit.

Have fun making your own piems and post them in a comment. Every once in a while I will post a piem.
