Built from Physics: How Humanity Shapes Matter, Harnesses Energy, and Engineers the Future

Everything we build begins with physics. A bridge carrying its load. A power grid balancing demand. A microchip processing information. A spacecraft crossing the darkness between worlds. Each depends on the same fundamental rules of matter, motion, energy, and information. Built from Physics is an accessible journey from first principles to the engineered world. Salim Youssef Najim connects familiar physical phenomena to the systems that shape modern civilization-including materials, machines, cities, energy networks, computing, intelligent technologies, and spaceflight. Rather than treating physics as a collection of formulas to memorize, the book begins with the questions that make science meaningful: What is physically happening? Why does it happen? How can an equation describe something we can see, build, test, or change? Across eight parts and forty chapters, readers explore how forces create motion, how energy moves and transforms, how waves carry information, how electricity powers technology, and how physics makes engineering possible. The journey then reaches beyond everyday experience to examine gravity, relativity, space, time, and the wider universe. Written with curiosity, clarity, and respect for the reader, Built from Physics is for students, technology enthusiasts, aspiring engineers, lifelong learners, and anyone who has looked at the world and wondered how it truly works. Physics is more than an academic subject. It is a way of seeing the hidden architecture of reality-and the foundation of everything humanity may build next.
