It's New T-Shirt Week!! (One for the Math Enthusiasts)

Jason English

On day four of New T-Shirt Week (!!), we've got one for all you math junkies. Order today and get a 10% discount—head over to the mental_floss store, add it to your cart, and use the code "math" during checkout. (You can click on either shirt image above.)

Imaginary number expert Amy Whinston is responsible for today's shirt. (I mean she knows her imaginary numbers, not that she's a number expert who is not real.) Well done, Amy! Here's a little bit about her:

"Amy Whinston teaches math at the University of Alaska. She loves math more than chocolate, but less than schnauzers."
