‎A New Modification of the Cloud Method of Determining the Elementary Electrical Charge and the Most Probable Value of that Charge. - [THE OIL DROP EXPERIMENT]‎

‎London, Taylor & Francis, 1910. 8vo. Bound with the original wrappers in recent full blue cloth with black lettering to spine. In ""The Philosophical Magazine"" for February 1910, vol 19, no. 110. The entire issue offered. Wrappers reinforced in margin, otherwise a fine copy. Pp. 209-228 [Entire issue: pp. 209-336].‎

‎First edition of Millikan's landmark experiment in which he first provided the definitive proof that all electrical charges are exact multiples of a definite, fundamental value, namely the charge of the electron which in essence made possible the measurement of the electrical charge. In this paper, Millikan makes ""the important discovery that individual drops always carried an exact multiple of the smallest charge measured - this being the first accurate measurement of the charge of the electron"" ( Davis, Science in the Making, Volume 3, 10-11). Today it is primarily known as the 'oil-drop experiment'. ""By 1909 Millikan was deeply involved in an attempt to measure the electronic charge. No one had yet obtained a reliable value for this fundamental constant, and some antiatomistic Continental physicists were insisting that it was not the constant of a unique particle but a statistical average of diverse electrical energies. Millikan launched his investigation with a technique developed by the British-born physicist H. A. Wilson" it consisted essentially of measuring, first, the rate at which a charged cloud of water vapor fell under the influence of gravity and then the modified rate under the counterforce of an electric field. Using Stokes's law of fall to determine the mass of the cloud, one could in principle compute the ionic charge. Millikan quickly recognized the numerous uncertainties in this technique, including the fact that evaporation at the surface of the cloud confused the measure of its rate of fall. Hoping to correct for this effect, he decided to study the evaporation history of the cloud while a strong electric Held held it in a stationary position.But when Millikan switched on the powerful field, the cloud disappeared" in its place were a few charged water drops moving slowly in response to the imposed electrical force. He quickly realized that it would be a good deal more accurate to determine the electronic charge by working with a single drop than with the swarm of particles in a cloud. Finding that he could make measurements on water drops for up to forty-five seconds before they evaporated. Millikan arrived at a value for e in 1909 which he considered accurate to within 2 percent. More important, he observed that the charge on any given water drop was always an integral multiple of an irreducible value. This result provided the most persuasive evidence yet that electrons were fundamental particles of identical charge and mass.Late in 1909 Millikan greatly improved the drop method by substituting oil for water. Because of the relatively low volatility of this liquid, he could measure the rise and fall of the drops for up to four and a half hours. Spraying the chamber with radium radiation, he could change the charge on a single drop at will. His overall results decisively confirmed the integral-multiple values of the total charge. As for the determination of e itself, Millikan found that Stokes's law was inadequate for his experimental circumstances because the size of the drops was comparable with the mean free path of the air. Using the so-called Stokes-Cunningham version of the law, which took this condition into account, by late 1910 he had computed a charge for e of 4.891×10-10 e.s.u. Realizing that the accuracy of this figure was no better than that of the key constants involved in the computation, Millikan painstakingly reevaluated the coefficient of viscosity of air and the mean-free-path term in the Stokes-Cunningham law. In 1913 he published the value for the electronic charge, 4.774±.009×10-10 e.s.u., which would serve the world of science for a generation."" (DSB). In 1923 Millikan became the first American-born Nobel laureate for his work on determination of Planck's constant on the basis of Einstein's theory of the photoelectric effect.‎

The technical description of Minkowski's hypothesis is the four-dimensional Space-time continuum....Minkowski's space-time hypothesis was in effect a restatement of Einstein's basic principle in a form that greatly enchanced its plausability and also introduced importent new developments. Hitherto natural phenomena had been thought to occur in a space of three dimensions and to flow uniformly through time. Minkowski maintained that the separation of space and time is a false conception"" thet time is itself a dimension, comparable to lenght, breadth and height: and that therefore the true conception of reality was constituted by a space-time continuum possessing these four dimensions. This strongly reinforced Einstein's objections to absolute concepts and supported his view of the relativity of events in nature.""

It then became clear by simple inspection of this ‘step ladder’ that the spectrum of K radiation of each element contains two strong lines (which Moseley called Ka (for the longer wavelength) and Kß (for the shorter) and that this pair of lines moves to shorter and shorter wavelengths in a monotonic fashion if one moves step by step from calcium to zinc Moseley's work made it clear once and for all that indeed the position number in the Periodic Table is equal to the number Z of positive elementary charges in the nucleus of an atom. It also showed that Z is more important for the spectroscopic and chemical properties of an atom than the atomic mass number A. This is evident in the case of the elements cobalt (Z = 27, A = 58.9) and nickel (Z = 28, A = 58.7), where even the order in A differs from that in Z.” (Brandt, The Harvest of a Century: Discoveries in Modern Physics in 100 Episodes) PMM 407Evans 62Norman 1599‎

‎Scarce first edition of the first book explicitly devoted to solar energy, ""Solar Energy and its Industrial Applications"", which coincided with the unveiling of Mouchot's largest solar steam engine, the so-called ""Sun Engine"", in 1869, which caused a revolution in the development of solar thermal power. His 1869 work constitutes a milestone of what we now call ""green energy"", as it laid the foundation for our understanding of the conversion of solar radiation into mechanical power driven by steam.Auguste Mouchot was a French mathematics teacher, who in the 1860'ies became famous as the designer (and patent-taker) of the first machine that generated electricity with solar thermal energy electricity by the exposure of the sun. Mouchot began his work with solar energy in 1860 after expressing grave concerns about his country's dependence on coal. His work on solar energy and on the development of his sun machine forms the basis for the later developments on solar energy. ""The work of Adams, Ericsson, and Shuman had been directly influenced by the solar conceptions of Augustin Mouchot, a man who arrived on the scene in nineteenth century France at precisely that moment when his ideas were likely to attract the most attention. It was a time when French industrial might was at a peak and her leaders open to new ideas, none more so than her emperor. In 1867, to commemorate the explosion of technology that had accompanied the industrial and artistic carnival over which he had presided for 15 years, France's Napoleon III decided to invite the whole world to an international exposition that he would host in Paris."" (Kryza, The Power of Light, p. 147). ""His initial experiments involved a glass-enclosed, water-filled iron cauldron, in which sunlight passed through a glass cover, heating the water. This simple arrangement boiled water, but it also produced small quantities of steam. Mouchot added a reflector to concentrate additional radiation onto the cauldron, thus increasing the steam output. He succeeded in using his apparatus to operate a small, conventional steam engine. Impressed by Mouchot's device, Emperor Napoleon III offered financial assistance, which Mouchot used to produce refinements to the energy system. Mouchot's work help lay the foundation for our current understanding of the conversion of solar radiation into mechanical power driven by steam.The publication of his book on solar energy, ""La Chaleur solaire et ses Applications industrielles"" (1869), coincided with the unveiling of the largest solar steam engine he had yet built. This engine was displayed in Paris until the city fell under siege during the Franco-Prussian War in 1871, and was not found after the siege ended."" (The Energy Library).‎
