Steam, Steel and Electricity

A technical-historical survey traces the development and mechanics of steam power, the evolution of iron into modern steel, and the rise of electrical science, blending historical narrative with clear explanations of underlying principles and practical construction. It outlines early engine forms and innovations that led to the modern steam engine, explains metallurgical advances and mass steelmaking processes, and follows electrical discoveries from simple experiments to the laws of induction, magnetism, and electromagnetism. Illustrative diagrams, accounts of influential contributors, and discussions of machinery, valves, and industrial applications accompany conceptual explanations to show how these technologies altered manufacturing, architecture, and everyday power use.
