Science of Mechanics e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The first edition of the English translation by Mr m'cormack of Mach's M eckanics was published in 1893, and was carefully revised by Professor Mach' himself. Since then two other editions of this translation have appeared, in which the altera tions contained in the successive German editions have been embodied in the form of appendices. In the seventh German edition, however, which appeared at Leipsic (f. A. Brockhaus) in 1912, there have been more profound modifications in the plan of Professor Mach's work, which are shortly referred to in the preface to that edition. Many things are added and some things are omitted. Among the parts omitted are the prefaces to all of the German editions except the first, and a new preface to the seventh edition has been added. The most extensive additions relate to recent historical re searches on the work of Galileo's precursors and the early work of Galileo himself; and the book is dedicated to the late Emil Wohlwill, of whose researches much use has been made.
