Eight Lectures on Theoretical Physics, Delivered at Columbia University in 1909. Translated by A.P. Wills by Max Planck, first published in 1915, is a rare manuscript, the original residing in one of the great libraries of the world. This book is a reproduction of that original, which has been scanned and cleaned by state-of-the-art publishing tools for better readability and enhanced appreciation. Restoration Editors' mission is to bring long out of print manuscripts back to life. Some smudges, annotations or unclear text may still exist, due to permanent damage to the original work. We believe the literary significance of the text justifies offering this reproduction, allowing a new generation to appreciate it.

In this classic of scientific literature, the Nobel Laureate and creator of the quantum revolution explores the basics of physics, concluding with an engrossing narrative of how he developed quantum theory. 1925 edition.

The present book has for its object the presentation of the lectures which I delivered as foreign lecturer at Columbia University in the spring of the present year under the title: "The Present System of Theoretical Physics." The points of view which influenced me in the selection and treatment of the material are given at the beginning of the first lecture. Essentially, they represent the extension of a theoretical physical scheme, the fundamental elements of which I developed in an address at Leyden entitled: "The Unity of the Physical Concept of the Universe." Therefore I regard it as advantageous to consider again some of the topics of that lecture. The presentation will not and cannot, of course, claim to cover exhaustively in all directions the principles of theoretical physics.-The Author, Berlin, 1909.From the TRANSLATOR'S PREFACE.At the request of the Adams Fund Advisory Committee, and with the consent of the author, the following translation of Professor Planck's Columbia Lectures was undertaken. It is hoped that the translation will be of service to many of those interested in the development of theoretical physics who, in spite of the inevitable loss, prefer a translated text in English to an original text in German. Since the time of the publication of the original text, some of the subjects treated, particularly that of heat radiation, have received much attention, with the result that some of the points of view taken at that time have undergone considerable modifications. The author considers it desirable, however, to have the translation conform to the original text, since the nature and extent of these modifications can best be appreciated by reference to the recent literature relating to the matters in question.-A. P. Wills.

First published in German in 1893, this classic work by Max Planck laid the foundation for our modern understanding of thermodynamics and the behavior of matter at the atomic and molecular scale. The book covers a wide range of topics, including the laws of thermodynamics, the kinetic theory of gases, and the behavior of electromagnetic radiation. It is an essential read for anyone interested in the history of science or the fundamentals of physics.
