Unequal

In Unequal, Eugenia Cheng explores how the equal sign is more than just a symbol of sameness, revealing a deeper world of shapes, symmetries, and logical ideas beyond simple calculations. She demonstrates that concepts of equality and inequality are nuanced and context-dependent, highlighting the vibrant complexity within mathematics. The book invites readers to see mathematics as a dynamic way of thinking rather than just a collection of rules, opening up new perspectives on human understanding and relationships.
