Pi day 2006
HAPPY PI DAY!
And as a special treat this day of 2006 I'mg oing to post some birthday pi! In otherwords I searched for the number string of the birthday's of some of my friends in the first 1 million digits of pi.
For example. My birthday is 09/06/1987
The string 09061987 was found at position 8,050,576 counting from the first digit after the decimal point. The 3. is not counted.
The string and surrounding digits:
27008830938531753819 09061987 98793372816734063723
Kit's birthday is 06/02/1986
The string 06021986 was found at position 172,306,079 counting from the first digit after the decimal point. The 3. is not counted.
The string and surrounding digits:
58399713708587055756 06021986 45222062914085598848
Ali's birthday is 10/28/1986
The string 10281986 was found at position 65,779,926 counting from the first digit after the decimal point. The 3. is not counted.
The string and surrounding digits:
38495451990659629914 10281986 39877736343070773834
Adam's birthday is 02/28/1987
The string 02281987 was found at position 110,909,641 counting from the first digit after the decimal point. The 3. is not counted.
The string and surrounding digits:
85961080809951110040 02281987 59338084025560633773
Marks birthday is 12/18/1986
The string 12181986 was found at position 102,904,985 counting from the first digit after the decimal point. The 3. is not counted.
The string and surrounding digits:
87092444583826596951 12181986 84846330006019408191
According to the website we are all lucky people I suppose.
Why can/can't I find my number in Pi? If we view Pi as a big, random string of numbers (which is close enough for our purposes), then we can figure out the odds of finding any string in the first 100 million digits of Pi:
Number length Chance of finding
1-5 100%
6 Nearly 100%
7 99.995%
8 63%
9 9.5%
10 0.995%
11 0.09995%
Happily, if you include the zeros, birthdays are 8 digits long -- so you have a 63% chance of finding your birthday in the first 100 million digits of pi. Note that if I added another 100 million digits, these odds would only go up to 86%, so it'll be a while before everyone can find their birthday in Pi.
But we all did find our birthdays! So happy pi day everyone. If anyone who I forgot want's to see if their birthday is in pi, the pi search page is...
