Nonstandard Notebook

"This is what every math book should be-an invitation to creativity and interaction. It makes my mathematical heart leap with joy. I need to buy many copies so that I can keep one copy to stare at but have several to use as actual notebooks in different ways, not to mention give them to everyone I know." -- Eugenia Cheng, author of the Los Angeles Times Book Prize-winning "Is Math Real?"
"I love the Nonstandard Notebook! Is it meditation or math? Both, really, and the result is pretty close to enlightenment." -- Larry Gonick, New York Times-best-selling author of "The Cartoon Guide to Geometry"
"This project reveals how joy and wonder can be both subtle and profound. The simple daily delight of writing, yet with new structure, might make you think about things you never thought before. In this notebook-artbook, Chartier and Langville take us on a surprising tour of the graceful glory and the provocative possibilities of lines! Backgrounds, when gently foregrounded, help us see life and humanness in the mathematics of simple things. As I beheld each page, all I kept thinking was how much fun it would be to scribe my thoughts here! What new contemplations might it inspire?" -- Francis Su, author of "Mathematics for Human Flourishing"
"What matters most is the space left blank. All the mathematics, all the artistry-it's only there as fodder for your imagination. . . . The pencil is yours." -- Ben Orlin, best-selling author of "Math with Bad Drawings," from the foreword
