The Analytical Theory of Heat is a seminal work in the field of thermodynamics, written by the French mathematician Joseph Fourier in 1878. The book is divided into three parts, each of which presents a different aspect of the theory of heat. In the first part, Fourier introduces the basic concepts of heat transfer and develops the mathematical tools needed to analyze it. He also discusses the behavior of heat in different materials, including solids, liquids, and gases.The second part of the book is devoted to the study of heat conduction. Fourier presents a detailed analysis of the flow of heat through different materials, including the effects of temperature, pressure, and other factors. He also develops a series of equations that describe the behavior of heat in different situations.In the third part of the book, Fourier explores the applications of his theory to practical problems. He discusses the behavior of heat in various industrial processes, such as steam engines and furnaces, and provides a detailed analysis of the behavior of heat in different natural phenomena, such as the Earth's atmosphere and the ocean.Overall, The Analytical Theory of Heat is a groundbreaking work that laid the foundation for the modern field of thermodynamics. It remains an important reference for scientists and engineers working in the field of heat transfer and thermodynamics, and is still widely read and studied today.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
