3.14 or a slice of applie pie?  Today marks a geeky tradition:  Pi day.  To celebrate the mathematical constant, geeks around the globe are talking over their meals about formulas and ending them with a slice of pie.  Ford is actually putting on a math formula contest to visitors of reddit.com.   Starting at 11 a.m., Ford engineers will post a new math problem every 3 minutes and 14 seconds, for a total of 42 questions in all.  The first person to solve each puzzle correctly will earn coveted "reddit gold," extended features for their reddit accounts.

How will you celebrate Pi day?
