Some Answers to Questions I Asks on March 21st

March 28th, 2015
Pi Day was on March 14th, and I waited a week to see if anyone would pick up on the REAL PI DAY NEWS.  Some did pick up on some of it, but not all of it.  So my post on March 21st explained some of it 3-digit Pi Day, 10-Digit Pi Day, and even 12- Digit Pi Days) and I left you with some questions to ponder.  Now, one week later, I’m back to answer some of those question.
Can you have Pi Day where date and time express more than 12-digits?
Yes!  March 14th, 159265 AD at 3:58 and 9 seconds.  It will be a 13-digit Pi Day.  It’s just a little less than 157,250 years away.  Save the date.  Mark it on your calendar.
How often do they celebrate Pi Day on Mercury? 
It takes Mercury about 88 Earth days to orbit the Sun, but their day is over 58 Earth days long – so the year is over before the end of the second day of the year.  So each year they have New Year’s Day and New Year’s Eve.  There is no room for Pi Day.  Those poor Mercurites, they don’t even know what they are missing.  But I’m wondering “How may Mercurites do you have to have in a room together for the chances are better than 50% that at least two of them will have the same birthday?  (Hint: If you have 3 in the same room the chances are 100% that at least two will share the same birthday.)
What do the Fibonacci sequence and Pi have in common?
They are both dandy reasons to have another mathematical holiday – party on!  Fibonacci day is celebrated on November 23 (11/23 or 1, 1, 2, 3).
