Eugenia Cheng Explores the Question, ‘Is Math Real?’

Children frequently ask questions such as, “Why does 1+1=2?” or “Why memorize multiplication tables?” Many of us stop asking as we grow older. But what if a mathematician encourages ongoing inquiry, prompting, “What’s the point of this question?” Imagine a scenario where 1 + 1 equals 1. This occurs when blending two paint colors into one new shade.

This perspective is central to mathematician Dr. Eugenia Cheng’s book, Is Math Real? How Simple Questions Lead Us to Mathematics’ Deepest Truths. Cheng argues that asking questions can reveal math’s inherent beauty. Her book examines how we use math in everyday life, challenging the rigid true/false dichotomy taught early in education.

The book provides examples where conventional math, like 1+1 equaling two, does not apply, and also delves into the concept of infinity. Is Math Real? encourages reconsideration of our relationship with math, emphasizing that curiosity and creativity, rather than strict right and wrong answers, drive the discipline.

Dr. Cheng’s work invites readers to engage with math in new and insightful ways. Her approach suggests that embracing questions is integral to understanding the deeper truths of mathematics. Her book encourages readers to reflect on the nature of math as a creative and dynamic field.
