Perhaps you've seen the posts on Facebook and Twitter. Maybe your Instagram feed is filled with artfully framed photos of baked goods. Maybe you've even seen signs and promotions at the grocery store or bakery.

Today, 3/14, is Pi Day. But instead of trying in vain to remember those formulas you learned back in high school geometry (hint: π r² or 2 π r), we suggest that you celebrate Pi Day with a nice slice of pie.
