Das Kreuz mit dem Quadrat

Can a cube pass through itself? Why is 2023 a special year? And what do you do with three lies that have only one truth? In his new book, science journalist and math author Holger Dambeck presents 100 new puzzles that encourage thinking and problem-solving. Not only while traveling but also in mathematics, it often holds true: the journey is the destination. Unlike many school assignments, Holger Dambeck does not provide solutions in his math puzzles; instead, he invites his readers to embark on their own journey of discovery. Because solutions need to be found, and that requires creativity, vigilance, and a joy for the unknown. Following the great success of his two puzzle books "Three Logicians Walk into a Bar" and "Blind Date with Two Unknowns," Holger Dambeck, author of the popular SPIEGEL column "Puzzle of the Week" since 2014, now presents his latest collection of 100 clever math puzzles in "The Cross with the Square." Enjoy the challenge!.
