I found an easy way to remember long numbers, first I made a table with 3 columns that going to the right are less and less common letters...
so anyway what you do is say you have the first 31 digits of pi:
3.1415926535897932384626433 83279 5
you translate that to letters via the table (I'm only using the first column for this one):
C A O A W T D S W C W M T F T C D C M O S D S O C C M C D F T W
Then find an English sentence that every word starts with these letters.
Could Anyone Own A Wagon That Doesn't Sparkle? Who Could Want Mine That Fails To? Certainly Didn't Cost Much On Sale. Does Someone Only Care Color? My Cover Doesn't Fit Too Well
And this little want ad and the phrase "Bad Cows FMT!" (No idea what fmt means maybe a shooing sound?)
will encode 31 digits of pi!
