Like the classic math allegory

The ambitions of this book take a special kind of author. An inventive, original thinker pursuing his calling with jubilant passion. A prodigy. Milo Beckman completed the graduate-level course sequence in mathematics at age sixteen, when he was a sophomore at Harvard; while writing this book, he was studying the philosophical foundations of physics at Columbia under Brian Greene, among others.

Milo Beckman has been addicted to math since a young age. Born in Manhattan in 1995, he began taking math classes at Stuyvesant High School at age eight and was captain of the New York City Math Team by age thirteen. His diverse projects and independent research have been featured in the *New York Times*, *FiveThirtyEight*, *Good Morning America*, *Salon*, the* Huffington Post*, the *Chronicle of Higher Education*, *Business Insider*, the *Boston Globe*, *Gothamist*, the *Economist*, and others. He worked for three tech companies, two banks, and a US senator before retiring at age nineteen to teach math in New York, China, and Brazil, and to work on this book.

“With charm, unwavering enthusiasm, and a lot of cartoons, *Math Without Numbers* waltzes the reader through a garden of higher mathematics.”

**—**Jordan Ellenberg, professor of mathematics, University of Wisconsin-Madison, author of *How Not To Be Wrong*

“So delightful! Mathematics is playful, surprising, and enchanting, but those qualities are often obscured behind intimidating equations and formalism. Milo Beckman brings them out into the open for everyone to share.”

**—Sean Carroll, author of ***Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime*

“*Math Without Numbers* explores deep mathematical topics—and shows how mathematicians think—in completely readable prose. The puzzles and games are bonuses. Very enjoyable.”

**—Will Shortz, crossword editor, ***The New York Times*

“The book’s accessible language and illustrations makes understanding some of the most complex (and possibly most intimidating) math concepts feel as effortless as breathing. Beckman’s approachable writing and Erazo’s delightful illustration combine to tell an insightful and entertaining story about math.”

**—Giorgia Lupi and Stefanie Posavec, co-authors of ***Dear Data* and *Observe, Collect, Draw!*

“This is the book for you if you’ve ever been curious about the wonderful ideas and concepts underlying modern math, but been too frightened to make a start. Milo Beckman gives us a friendly introduction to unfamiliar concepts and ideas that show why modern math is such a fascinating and rewarding branch of human thought.”

**—**Graham Farmelo, author of *The Universe Speaks in Numbers*

*“Math Without Numbers *offers an accessible and whimsically illustrated glimpse of what pure mathematicians study, all while capturing the playful spirit with which they do it.”

**—**Grant Sanderson, creator of 3blue1brown

“A cheerful, chatty, and charming trip through the world of mathematics and its relation to the world of people—and not a number in sight! Everyone should read this delightful book. Even mathematicians.”

—Ian Stewart, professor of mathematics, University of Warwick, author of*Do Dice Play God?*
