If you have the kind of Facebook or Twitter newsfeed that I have, you have likely figured out that March 14, 2015 is pretty darned special. And at 9:26 a.m., there’s even more reason to celebrate. That exact time is the ultimate for us math geeks who are also fond of π. If you write this date and time using only numbers (and strategically placing a decimal point to the right of 3), you get:

3.1415926

And that’s **the longest expression of pi we’ve seen in 100 years on Pi Day**.

So forget making pies. We here at Math for Grownups are going to be celebrating bigger! And better! From today through midnight on Pi Day (that’s this Saturday, by the way), you’ll have a chance to win great prizes!

### π Plates

I’m thrilled to partner with **Uncommon Goods**, one of my most favorite online retailers for unique gifts and crafts, to offer one lucky winner a set of these clever pie plates. (“i eight sum pi,” they say.)

### T-shirt

I designed this shirt just for this celebration. You’ll want to remember this momentous occasion — you know, share it with your grandchildren. The t-shirt is 100% cotton, and you can order it in standard or ladies cut.

### Mug

Have a little Pi Day with your coffee or tea? Sip away, while letting your math geek flag fly!

*Math for Grownups* and *Math for Writers*

Of course, some lucky winner will take home one of my books *Math for Grownups *or *Math for Writers*.

### Free Online Learning

And last, but not least, I’ll be offering one person the opportunity to take my new online course, “**Stats for Writers**,” at no charge.

So how can you win? * If you already receive my newsletter, you are already in the drawing*. If you’re haven’t signed up? Just complete the form below. After midnight on March 14, I’ll have my computer randomly select the winners. I’ll post their names here and contact them directly.
