What's the Use?: The Unreasonable Effectiveness of Mathematics  
BY Professor Ian Stewart

Summary

Ian Stewart’s What’s the Use?: The Unreasonable Effectiveness of Mathematics explores the surprising ways mathematics shapes the modern world and challenges the common belief that math is only about abstract theories and classroom exercises. Stewart explains that many mathematical discoveries, even those that seemed useless at first, later became essential for technology, science, medicine, and everyday life. 

Through engaging examples, he shows how mathematics influences areas such as satellite navigation, computer security, medical procedures, voting systems, and digital technologies. The book reveals that mathematics often works quietly behind the scenes, providing the hidden structures that make modern society possible. Stewart’s main message is that mathematics is not just a tool for calculation but a powerful way of understanding and transforming the world around us.
