Bake Infinite Pie With X Y

"X and Y are desperate to bake infinite pie! With the help of quirky and uber-smart Aunt Z, X and Y will use math concepts to bake their way to success!"--

From imaginary numbers to the fourth dimension and beyond, mathematics has always been about imagining things that seem impossible at first glance. In x+y, Eugenia Cheng draws on the insights of higher-dimensional mathematics to reveal a transformative new way of talking about the patriarchy, mansplaining and sexism: a way that empowers all of us to make the world a better place. Using precise mathematical reasoning to uncover everything from the sexist assumptions that make society a harder place for women to live to the limitations of science and statistics in helping us understand the link between gender and society, Cheng's analysis replaces confusion with clarity, brings original thinking to well worn arguments - and provides a radical, illuminating and liberating new way of thinking about the world and women's place in it.

With bright, whimsical art, this humorous guessing game and visual puzzle from a legendary graphic designer will delight design fans of all ages. Is that a table--or a cow? You won't believe your eyes as this humorous guessing game and visual puzzle from award-winning graphic designer Seymour Chwast, co-founder of the legendary Push Pin Studios, transforms a simple object into something completely different. Each delightfully drawn initial image is revealed, after a page turn, to be part of a larger or more elaborate thing. The objects become both more complex and sillier--ball and toaster? Nah, it's a bulldog--as we make our way to the final transformation, a pair of scissors that becomes the face of the cat we've been waiting for. Readers young and old will giggle as they see the importance of recognizing odd but simple shapes and learning how they work together to form more complicated images.

How both logical and emotional reasoning can help us live better in our post-truth world In a world where fake news stories change election outcomes, has rationality become futile? In The Art of Logic in an Illogical World, Eugenia Cheng throws a lifeline to readers drowning in the illogic of contemporary life. Cheng is a mathematician, so she knows how to make an airtight argument. But even for her, logic sometimes falls prey to emotion, which is why she still fears flying and eats more cookies than she should. If a mathematician can't be logical, what are we to do? In this book, Cheng reveals the inner workings and limitations of logic, and explains why alogic -- for example, emotion -- is vital to how we think and communicate. Cheng shows us how to use logic and alogic together to navigate a world awash in bigotry, mansplaining, and manipulative memes. Insightful, useful, and funny, this essential book is for anyone who wants to think more clearly.

This interactive mystery shows math isn't just about numbers—it’s about imagination! An explorative and creative approach to the world of mathematics.

Category theory reveals commonalities between structures of all sorts. This book shows its potential in science, engineering, and beyond.

An uplifting message of hope for the future and pride in your history, inspired by a mother's experience of being the only Black child in her classroom. Who do you see when you look in the mirror? Emphasizing the strength, creativity, and courage passed down through generations, A History of Me offers a joyful new perspective on how we look at history and an uplifting message for the future. Being the only brown girl in a classroom full of white students can be hard. When the teacher talks about slavery and civil rights, she can feel all the other students' eyes on her. In those moments she wants to seep into the ground, wondering, is that all you see when you look at me? Having gone through the same experiences, the girl's mother offers a different, empowering point of view: she is a reflection of the powerful women that have come before her, of the intelligence, resilience, and resourcefulness that have been passed down through the generations. Her history is a source of pride, a reason to sit up straight and recognize everything beautiful and powerful in herself. What really matters is what we see when we look in the mirror, and what we want to become. Inspired by the authors' experiences in school and as a parent, Adrea Theodore’s debut picture book is a powerful testament to the past as well as a benediction for the future. Erin Robinson's digital illustrations feature a wealth of texture and a bold, saturated palette, bringing this warm message of empowerment to life.

The study of the mapping class group Mod(S) is a classical topic that is experiencing a renaissance. It lies at the juncture of geometry, topology, and group theory. This book explains as many important theorems, examples, and techniques as possible, quickly and directly, while at the same time giving full details and keeping the text nearly self-contained. The book is suitable for graduate students. A Primer on Mapping Class Groups begins by explaining the main group-theoretical properties of Mod(S), from finite generation by Dehn twists and low-dimensional homology to the Dehn-Nielsen-Baer theorem. Along the way, central objects and tools are introduced, such as the Birman exact sequence, the complex of curves, the braid group, the symplectic representation, and the Torelli group. The book then introduces Teichmüller space and its geometry, and uses the action of Mod(S) on it to prove the Nielsen-Thurston classification of surface homeomorphisms. Topics include the topology of the moduli space of Riemann surfaces, the connection with surface bundles, pseudo-Anosov theory, and Thurston's approach to the classification.
