In honor of the esteemed mathematical constant, we invite you to celebrate Pi Day with us!

If you’re a math geek, we have you covered:

- A history of pi (1989)
- Pi, a sourcebook (1997)
- Pi in the sky : counting, thinking, and being (1992)
- Easy as pi? : an introduction to higher mathematics (1999)
- Pi : a biography of the world’s most mysterious number (2004)

If your mathematical knowledge could use a little refresher, maybe try this one instead:

You could listen to multiple people recite the first 50 digits of pi in various styles, including to the tune of the Battle Hymn of the Republic (my personal favorite), in the voice of Bullwinkle, as an infomercial, in Latin, while laughing, in Morse Code, and while eating actual pie.

Have insomnia? Listen to the first 1,000 digits of pi for 9.5 minutes straight… problem solved!

But most importantly, if you want to **celebrate by eating pie** we can help you make one! Winner of the Best Title Award definitely goes to Pies and tarts with schmecks appeal by the inimitable Edna Staebler. A close second goes to Tarts with Tops On by Tamasin Day-Lewis. But take your pick from amongst a wide array of pie cookbooks to find the right one for you.

And most importantly, we wish you infinite pi(e).
