The Mathematics Behind Engineering: How Explains Waves, Circuits and Systems

What if the mathematics behind engineering actually made sense?Most textbooks hand you equations and ask you to memorise them. This book does the opposite. Every formula is built from scratch, every concept begins with a story you can picture, and nothing is left unexplained. From the moment Euler wrote down the most beautiful equation in mathematics to the four laws that predicted Wi-Fi before wireless technology existed, the ideas in this book are ones that genuinely changed the world.Written by a 17 year old who wanted to understand not just how the maths works but why, this book covers everything from complex numbers and calculus through to Fourier analysis, Maxwell's equations, control systems and digital signal processing. It is written for anyone who has ever looked at an engineering textbook and felt the explanation was missing.You do not need a physics background. You do not need to be an engineer. You need curiosity and a willingness to follow an idea from its first principles all the way to where it becomes useful.By the end, you will not just know these tools. You will understand them.
