What is math? And how exactly does it work? In How to Bake Pi, math professor Eugenia Cheng provides and accessible introduction to the logic of mathematics-sprinkled throughout with recipes for everything from crispy duck to cornbread-that illustrates to the general reader the beauty of math. Rather than dwell on the math of our high school classes, with formulas to memorize an confusing symbols to decipher, Cheng takes us into a world of abstract mathematics, showing us how math can be so much more than we ever thought possible.
