Böcker av Oliver Lodge

Knowing there was no money in science, Vincenzo Galilei wanted his son to become a cloth-dealer. While the young Galileo was disobeying his father and cultivating an unwholesome interest in geometry, Tycho Brahe was maintaining the impoverished Johannes Kepler and his entire family. Not long after this, a certain Cambridge mathematician noticed a strange phenomenon that became known as 'the precession of the equinoxes', before formulating his law of gravity. In this fascinating collection of lectures, first published in 1893, the eminent Professor of Physics Oliver Lodge (1851-1940) takes the reader on a tour of the history of astronomy. Including biographical notes on landmark astronomers, more than a hundred illustrations, and simple explanations of important concepts, this engaging book's range from the geocentric theory of the universe to the discovery of Neptune and the calculation of tides. It remains highly accessible to the general reader today.

In 1889, a year after both he and Heinrich Hertz discovered electromagnetic waves and for the first time demonstrated the truth of Maxwell's great theory of the electromagnetic field, physicist Oliver Lodge (1851-1940) published his deepest reflections on the nature and meaning of electricity, how it originates, and its different manifestations. There had been great scientific advances - the work of Faraday and Maxwell, his own experiments and those of Hertz - and a revolution in technology. There were also puzzling questions. What is the connection between electricity and the ether that occupies space? How does electricity manifest itself in matter? Why does it come in fixed units? The discovery of the electron eight years later would offer crucial answers. Always lucid and direct, with a gift for making the difficult seem simple, Lodge engages the reader with his fascination for the subject, much as he did in his famous lectures.

As a result of being asked to give public lectures on the subject, the eminent physicist Oliver Lodge (1851-1940) published in 1892 a pioneering study of the protection of buildings, cables and telegraphic instruments from the devastation caused by lightning strikes. This work led him almost immediately to the discovery of electromagnetic wave transmission and ultimately to the development of a version of radio telegraphy. Lodge also saw that many of the current theories about the nature of lightning were seriously in error, and his investigations led to a number of significant changes in the design of lightning conductors and lightning guards. Some of the methods and procedures that Lodge advocated have since become standard practice. They are described with Lodge's characteristic flair and accompanied by a wealth of illustrations that give a fascinating insight into how contemporary scientists and engineers tackled this significant problem.

The discovery in 1897 of the electron, the first subatomic particle, led to rapid advances in our knowledge of atomic structure, the solid state, radioactivity and chemistry. It also raised major questions. Was the electron point-like or did it have structure? Was there a positive electron? What did the positive part of the atom look like? Did a hydrogen atom have one electron or a thousand? Published in 1906, this expository account by leading physicist Sir Oliver Lodge (1851-1940) examines the spectacular phenomena of cathode rays in evacuated tubes, the fixed units of charge observed in electrolysis, and the puzzling regularities in atomic spectra. Lodge knew most of the pioneers in the field, and his enthusiastic descriptions of their work and clear analyses of the problems as well as successes paint a vivid picture of the excitement of cutting-edge research and the scientific process in action.

The early 1890s saw the development of wireless telegraphy. Although the behaviour of radio waves had been predicted by James Clerk Maxwell, the production of a working coherer occupied some of the greatest practical physicists of the time. A giant in the field was Heinrich Hertz (1857-94), who was among the first to discover that radio waves could travel independently of wires. When Hertz died, his work was continued and soon led to the development of the first wireless radios. This book, published in 1900, is the third edition of Sir Oliver Lodge's popular explanation of Hertz's work. Including the Royal Institution lecture that Lodge (1851-1940) gave in 1894, along with detailed diagrams, it covers the basic principles of radio waves and some of the theory surrounding telegraphic technology. Also included in this reissue is Lodge's 1924 lecture on electrical precipitation, discussing the scintillating possibility of altering atmospheric conditions through the use of electrical charges.

The physicist Sir Oliver Lodge (1851-1940) made significant contributions to the study of electrons, electromagnetic waves, X-rays, radio and telegraphy, earning him the Rumford Medal, the Faraday Medal and, in 1902, a knighthood. In addition to serving as President of the Physical Society, Lodge succeeded F. W. H. Myers as President of the Society for Psychical Research, an organisation devoted to the study of paranormal phenomena. In this work, first published in 1908, Lodge discusses the controversy between science and faith, showing how the self-sufficient laws of 'orthodox science' may be reconciled with the divinely ordered universe of 'orthodox religion'. Immensely popular from the moment of its publication, the book reached its twenty-first printing in 1928. This sixth edition of 1909 conveys the full scope of Lodge's ambitious project, including his treatments of evolutionary science, church reform and the immortality of the soul.

The well-known physicist and member of the Society for Psychical Research tells the story of his life. Includes, amid much else, discussions of his ether experiments, the development of wireless radio, and psychical experiments. Illustrated.
