Mage Merlin’s Unsolved Mathematical Mysteries

"This book is wonderfully unique — an irresistible call to join the quest for the treasures of mathematics." – TaiDanae Bradley, coauthor of Topology: A Categorical Approach and creator of the math blog Math3ma"An elegant, charming collection of 16 mathematical jewels: problems so simple they can be explained in a single page, yet so hard they can't be solved in a single century." – Ben Orlin, author of Math with Bad Drawings and Change is the Only Constant: The Wisdom of Calculus in a Madcap World"Taste the sweet enchantment of this medley of unsolved problems. Some are classical, and some are less well known, but all are easy to understand, because the authors have recast them in novel ways to entice both new and seasoned mathematical explorers. Devadoss and Harvey will captivate the mathematical yearning within each one of us." – Francis Su, Professor of Mathematics, Harvey Mudd College; Former President, Mathematical Association of America; author of Mathematics for Human Flourishing"This is a fun and delightfully illustrated text covering a wide range of accessible topics from the recreational to the unsolved. Each is presented as a mystery (as all good mathematics is!), spanning geometry, combinatorics, number theory, and beyond. A dedicated reader will derive great satisfaction from wrestling with the challenges presented here." – Alex Kontorovich, Professor of Mathematics, Rutgers University; Dean of Academic Content, National Museum of Mathematics"This unique book will charm and delight mathematical explorers of all ages with its beautiful illustrations, captivating story, and unsolved mathematical challenges that range from geometry to number theory and more." — Forbes"Highly recommended."  — CHOICE
