# Pi Day!

### Thursday, March 14, 2013

That's not a typo, it's pi day today! For those who don't recall from math, pi is the ratio of a circles circumference to its diameter and it crops up all over math, science and engineering. Like the natural log, e, and a few other significant constants. One of the decimal approximations is 3.14, (hence, Mar 14). In two years, it will be 3.14.15 or the first 5 digits in the infinite non-repeating series.

And tangentially related:

Speaking of pie though, I found some rhubarb at the store the other day and we have guests coming over for dinner on Saturday night. That means strawberry rhubarb pie with crumble topping! Yum! While that will probably send me over my calorie range, I will enjoy baking it, eating it and then running it off the next day!
