The pamphlet of fifty-eight pages entitled Die Geschichte und die Wurzel desS atzes von derE rhaltung derA rbeit. Vortrag gehalten in der k. bhm. Gesellschaft der Wissenschaften am 15, Nov. 1871 von E. Mach, Professor derP hysik ander Universit tP rag was published atP rague in 1872, and a second unaltered edition at Leipzig (B arth) in 1909. To this second edition (pp. iv, 60) were added a short preface and a few notes by Mach himself. This preface is translated below. Quite apart from the interest which must attach to the first sketch of a way of regarding science which has become of such great importance to students both of science and of the theory of knowledge, this pamphlet is quite essential to the thorough understanding of Mach swork. Li the first place, it contains a reprint of Mach sarticle (1868) on the definition of mass, which is, perhaps, his most important contribution to mechanics; and, in the second place, the discussion of the logical root of the principle of the conservation of energy is fuller than that in any of his later publications. I In the title of this translation, A rbeit is translated byE nergy as this word conveys a better idea, at the present time, than the older and more literal equivalent of Work. In the text on the other hand, the word Work will always be iiscd, as it corresponds more closely to the terminology of science at the time of the first publication of this essay.(Typographical errors above are due to OCR software and don't occur in the book.)About the Publisher Forgotten Books is a publisher of historical writings, such as: Philosophy, Classics, Science, Religion, History, Folklore and Mythology.Forgotten Books' Classic Reprint Series utilizes the latest technology to regenerate facsimiles of historically important writings.
