Several people have asked me recently what I do for "fun" -- when I am not at work (but I repeat myself).
I thought I'd share one thing today. To stay sharp as I get older, I have memorized the first 24,100 digits of pi
Perhaps after I retire I will memorize them in the correct order.
Corollary:
Memorize the numbers 0 to 9... and you have memorized all possible digits of PI... alas not in the correct order, but it's a start.
@spaf Perhaps when you retire you could take up playing the triangle. It only makes one note, but believe it or not, there are instructional videos on YouTube (I just checked).
@spaf lol, 0,1,2,3,4,5,6,7,8,9 ?
@spaf With the magic of Unix tools and this website: http://www.geom.uiuc.edu/~huberty/math5337/groupe/digits.html I can get you to 100k, or 4x your current spot! I downloaded, ripped out the HTML, leaving just the digits and ran this command:
cat digits_of_pi.txt | sed -re 's/[^0-9]//g;s/(.)/\1\n/g' | sort | uniq -c
That outputs:
9999 0
10138 1
9908 2
10026 3
9970 4
10027 5
10027 6
10025 7
9978 8
9902 9
Or about 10,000 of each digit! Enjoy.
