What's the Use?

In "What's the Use?", esteemed mathematician Ian Stewart reveals how math is integral to understanding the world around us, from technology to healthcare. Rather than merely focusing on computations, he illustrates how mathematical concepts empower significant achievements, including space exploration and organ donation. By exploring diverse applications—like the trigonometry that keeps satellites in orbit and the prime numbers used in security systems—Stewart demonstrates that math is not just relevant, but fundamental to the fabric of our existence.
