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...

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...

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...

Sir Oliver Lodge (1851 1940) was a physicist instrumental in the discovery of electromagnetic waves: the basis of today's radio and X-ray technology. He came from humble beginnings. After suffering at the hands of violent masters and schoolmates during his childhood, Lodge went on to teach physics and chemistry to young women at Bedford College in London. Later, he was appointed professor of physics at the University of Liverpool, and became known for his public lectures on a vast range of topics, from the comic faults of phonographs to the medical applications of X-rays. Whether seeing the...

Among the widely agreed facts of physics in the late nineteenth century was the existence of luminiferous ether: the medium through which light was thought to travel. Theorised to be a highly rarefied substance, the ether accounted for the movement of light, gravity and even heat across a vacuum. It also had great implications for spiritualism. Where thought was not proven to be a result of chemistry in the brain, the presence of ether allowed for the idea that cognition and emotion might exist independently of a physical body. First published in 1925, this monograph by the eminent physicist...

In his study of optics, Newton postulated that light, like sound, must be carried through a medium, and that this medium must exist even in a vacuum. By the late nineteenth century, this theoretical substance was known as the luminiferous ether. But the ether theory faced several problems. If the earth moved through ether, there would be ether wind, and light travelling against the flow would move more slowly than light travelling with it. That was soon disproven. Nor could the ether be stationary: by 1905, Einstein's work on relativity had disproven absolute motion. In this fascinating...

Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfangen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen fur die historische wie auch die disziplingeschichtliche Forschung zur Verfugung, die jeweils im historischen Kontext betrachtet werden mussen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.
