‎First printing of Hermann's publication on the historical development and foundation of physics. Today she if famous for her pioneering work with respect to the interpretation of quantum theory, the present paper being her most extensive on the philosophical aspects of the development of research in physics.Attempts to interpret and understand what was then new and very puzzling physics were of great contemporary importance when Grete Hermann entered the field, and her work in physics was mainly related to the interpretation of quantum mechanics. More specifically, her main work in physics was on the philosophical foundations of quantum mechanics, the significance of modern physics for the theory of knowledge, and causality in physics. She was one of the active early contributors to the historic debates on causality in quantum mechanics, and on the completeness of quantum mechanics and its description of reality.Hermann's work during the 1930s reveals the influence of her background in the neo-Kantian school, yet it also owes much to the way in which Heisenberg and Weizsäcker had interpreted Bohr's doctrine of the indispensability of classical concepts in the description of experience.Heisenberg has written that Grete Hermann came to Leipzig for the purpose of challenging the philosophical basis of atomic physics. Heisenberg devoted an entire chapter of his book ""Physics and Beyond: Encounters and Conversations"" to a reconstruction of discussions that he had on quantum mechanics and Kantian philosophy with Grete Hermann and Carl Friedrich von Weizsäcker.‎

‎First edition of Heron's main work, being his first publication. The work stimulated and contributed substantially to the interest in pneumatics that arose suddenly in the late 16th century and led to the work of Toricelli and Boyle. The ""Pneumatics"" was not published in Greek until 1693. It is one of the major sources to our knowledge of the techniques and mechanics of Antiquity, and the many hydraulic and mechanical inventions by Hero are here depicted for the first time in print. The work includes studies of pneumatics and mechanics and include 89 illustrations of different inventions, such as siphons, fountains, engines, an account of a small stationary steam-engine (which is of the form now known as Avery's patent, the double-force pump etc., which ""by the union of (compressed) air, earth, fire, and water, and the concurrence of...elementary principles..., supply the most pressing wants of the human life, (or) produce amazement and alarm."" The book describes many gadgets and magical tricks and includes the first suggestion of a steam engine (see f. 52). - Sarton, Introduction...Vol. I pp. 208 ff. - Adams H:369 - Poggendorff I: 1084.‎

‎First appearance of this importent paper in optical theory in which Herschel described how to free lenses from the aberration for two axis points, one of which is infinitely distant. It is known as Herschel's condition. ""Sir John Herschel gave the condition which must be satisfied in order that a symmetrical optical system, free from spherical aberration for two conjugate axial points, may also be free from spherical aberration for two neighbouring and conjugate points upon the axis of the system" but Herschel's condition applies only to first order aberration, i.e. to aberration depending upon the cube of the inclination of the ray to the axis. Abbe shewed, later, that this condition could be included in a wider result, viz. that the spherical aberration, supposed zero, is stationary for axial variations provided that the incident and emergent rays for two conjugate axial points, associated with modified magnification m, satisfy the relation.

Internally clean. Pp. 8.‎

‎First edition, offprint, with the author's presentation inscription to Professor John Tyndall - the father of the Greenhouse Effect, heat radiation and global climate research - of this important paper, in which Herschel promotes the role of the devine in the natural order. Herschel, now famous for originating the use of the Julian day system in astronomy, naming seven moons of Saturn and four moons of Uranus, his investigation in colour blindness and the chemical power of ultraviolet rays, did much to promote the public understanding of science . The present paper constitutes one of his most widely read and popular works. ""During his life John was immensely celebrated, his name epitomizing science to the public, much as that of Einstein did in the next century."" (DSB)Though intended for a popular audience ""On the Origin of Force"" is one of the most important sources for understanding Herschel's general approach to science. A contemporary review of the paper states: ""The article is well worth reading for those who wish to realise the enormous benefit which has been rendered to science by banishing the indefinite uee of the word force and by introducing the term energy, restricting the use of force to the meaning attached to it by Newton. Sir John Herschel still speaks of the ""conservation of force"" (as did likewise Helmholtz, who, however, very early introduces the term Arheitskraft, power to do work, thus removing all ambiguity).Herschel and Tyndall corresponded throughout their mature lives and they shared an overall view on God's place in science. ""In the only case in which we are admitted into any personal knowledge of the origin of force, we find it connected (possibly by intermediate links untraceable by our faculties, but yet indubitably connected) with volition, and by inevitable consequence with motive, with intellect, and with all the attributes of mind in which-and not in the possession of arms, legs, brains, and viscera-personality consists."" (Herschel, rrom the present paper). Tyndall agreed in stating that: ""An inscrutable power of which we know no more than job did, when he said, 'Can man by searching find this power out?'. (Tyndall's ""Belfast Address"").‎

Nevertheless, his reminiscence was enough to spark further exploration, eventually resulting in the modern understanding of fluorescence. In fact, even today, quinine is one of the most commonly utilized fluorophores for spectroscopy, enjoyed by many for the strange, but beautiful fluorescence that was first observed, but unable to be unexplained, by Herschel.‎

‎First edition of Herschel's important paper on his observations of the rings of Saturn. ""Saturn exercised a special fascination for Herschel, and between 1789 and 1808 he devoted seven papers and part of an eighth to the planet, its ring, and its satellites.On 19 August 1787 Herschel suspected he had found a sixth and previously unknown satellite, but he was not able to confirm this until 28 August 1789, when his forty-foot telescope came into commission. A few days later he found a seventh satellite. For some months he carefully tracked the satellites, establishing for Mimas and Enceladus periods within seconds of the modern values, and giving evidence to show that Iapetus rotates in its period of revolution.He also made careful observations of the rings, which he believed to be solid. As the earth happened to be in the plane of the ring structure at the time, he compared the thickness of the ring when seen edge-on with the diameter of Jupiter's satellites"" and although his estimate exceeds modern values, his method showed that the thickness did not exceed a few hundred miles.""

‎First appearance of an importent paper on the THEORY OF ELASTICITY.""At the beginning of 1883, Hertz again became interested in a problem of elasticity. Now it was the question of bending of an infinite plate floating in water and normally loaded at one point. He found that the plate deflects downward under the load but at a certain distance from the load deflection become negative. Then, at an increased distance, they again become positive, and so on. Thusthe surface is wavy, and the high of the waves rapidly diminishes with increase of the distance from the load. He arrived, in this way, at the paradoxical conclusion that a plate, heavier than water, can be made to flow by loading it at the center, The explanation is that due to bending the plate aquires the form of a shell and can press out more water than is equivalent to its own weight.""(Timoshenko ""History of the Strenght of Material"" p.349).‎

""His [Hertz'] discovery of the properties of reflection, refraction, and polarization in electricity, with this wave theory of electrical motion, laid the foundation of radiotelegraphy and radiotelephony."" (Milestones of Science, p 47.)""Experimental proof by Hertz of the Faraday-Maxwell hypothesis that electrical waves can be projected through space was begun in 1887, eight years after Maxwell's death.

‎First edition of Hertz's seminal paper on electromagnetic waves in which he empirically demonstrates Maxwell's equations. This discovery and its demonstration led directly to the invention radio of communication, television and Radar.Hertz demonstrates what Maxwell had predicted that electromagnetic waves radiated in space with the speed of light. Hertz determined these waves to be of greater length than light and that they could be reflected.""Experimental proof by Hertz of the Faraday-Maxwell hypothesis that electrical waves can be projected through space was begun in 1887, eight years after Maxwell's death. The two main requirements were (a) a method of producing the waves, supposing that they existed, and (b) a method of detecting them once they were produced."" (PMM, 377.). In the present paper Hertz ""describes the apparatus that he had devised for the detection and measurement of electromagnetic waves, the key to his later success. To prove that electromagnetic waves can be projected through space it was necessary to devise a means of both producing the waves and, more difficult at the time, of detecting them once produced.""

(DSB, VI, 348b.)In ""Ueber einen Einfluss des ultravioletten Lichtes auf die electrische Entladung"" Hertz describes for the first time in history the phenomenon that the sparking distances between two electrodes is increased when ultra-violet light falls on the negative conductor.
