How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use

** "How It Works" by Archibald Williams is an early 20th-century book that simplifies science and technology for everyday people. Motivated by common questions about how things work, the author breaks down tricky concepts like steam power, electricity, light, heat, sound, hydraulics, and optics. Instead of getting lost in complicated details, the book focuses on the basic ideas behind these forces and how they power machines we use all the time. With clear explanations and helpful pictures, it shows how everything from steam engines to electrical devices function, even comparing our own bodies to machines to make things easier to understand. **
