Social and cultural values and anxieties at the time of general crisis, as identified by Paul Forman, strongly affected the language of the debate. At the same time, individual philosophical positions presented as strongly-held principles were in fact flexible and sometimes reversible to almost their opposites.

This article is published with open access at Springerlink.com Abstract. The quantum theory of dispersion was an important concep- tual advancement which led out of the crisis of the old quantum theory in the early 1920s and aided in the formulation of matrix mechanics in 1925. The theory of Charles Galton Darwin, often cited only for its reliance on the statistical conservation of energy, was a wave-based attempt to explain dispersion phenomena at a time between the the- ories of Ladenburg and Kramers. It contributed to future successes in quantum theory, such as the virtual oscillator, while revealing through its own shortcomings the limitations of the wave theory of light in the interaction of light and matter. After its publication, Darwin's theory was widely discussed amongst his colleagues as the competing inter- pretation to Compton's in X-ray scattering experiments. It also had a pronounced influence on John C. Slater, whose ideas formed the basis of the BKS theory. 1 Introduction Charles Galton Darwin mainly appears in the literature on the development of quantum mechanics in connection with his early and explicit opinions on the non- conservation (or statistical conservation) of energy and his correspondence with Niels Bohr.

  • The Prodigious Life and Untimely Death of “Harry” Moseley
    The prodigious life and untimely death of “Harry” Moseley Bretislav Friedrich Fritz Haber Institute of the Max Planck Society, Faradayweg 4-6, D-14195 Berlin “My Harry was killed in the Dardanelles” is the entry from 10 August 1915 in the diary of the mother of Henry (“Harry”) Gwin Jeffreys Moseley. He was shot on that day in the head during the failed Anglo-French invasion of the Ottoman Empire from the sea. The previous year, when he volunteered to join Lord Kitchener’s New Army, he was nominated for two Nobel Prizes, one for chemistry and one for physics, for his work on X-ray spectroscopy and atomic structure. Moseley’s tragic death at age 27 was widely reported not just in the Allied countries, but also in Germany. Its futility fired up Ernest Rutherford, Moseley’s mentor, to write an indignant letter to Nature: “It is a national tragedy that our military organization at the start of the war was so inelastic as to be unable, with a few exceptions, to utilise the scientific services of our men, except as combatants in the firing line. Our regret for the untimely death of Moseley is all the more poignant.” Three years before, as Rutherford’s affiliate at the University of Manchester, Moseley recognized that “a platinum target [upon electron impact] gives out a sharp line [X-ray] spectrum … which [a] crystal separates out [into monochromatic lines] as if it were a diffraction grating … There is here a whole new branch of spectroscopy which is sure to tell one much about the nature of an atom.” This letter of Moseley, addressed, as so many of his other letters, to his mother, marks the beginning of X-ray spectroscopy.

  • Balfour V. Huxley on Evolutionary Naturalism: a 21St Century Perspective
    S & CB (2003), 15, 41–63 0954–4194 JOHN GREENE Balfour v. Huxley on Evolutionary Naturalism: A 21st century Perspective This essay begins by setting forth the conflicting prophecies, in 1895, of Arthur James Balfour and Thomas Henry Huxley concerning the probable course of Western culture in the twentieth century if Huxley’s ‘scientific naturalism’ were to prevail over Balfour’s theistic conception of the relations between science and religion. The essay then examines some leading developments in the physical, biological, and social sciences and in philosophy and theology since 1900 to determine which of these prophecies, if either, proved to be truly prophetic. The author concludes that Balfour was the better prophet. Keywords: evolution, naturalism, positivism, emergence, metaphor, science, philosophy, theology. In 1895, Arthur James Balfour, a philosophically trained Scottish politician- statesman then serving as Chancellor of the Exchequer, published a book enti- tled Foundations of Belief, Being Notes Introductory to the Study of Theology containing a searching criticism of the evolutionary naturalism which Thomas Henry Huxley had labeled ‘scientific naturalism’. The naturalism underlying positivism, agnosticism, and empiricism, Balfour argued, rested on two grounds: (1) it reduced human experience to sense perception with the result that the only knowledge available to human beings was knowledge of phe- nomena, the things that appear to our senses, and the laws connecting them; and (2) it viewed human nature in all its aspects as

  • Who Got Moseley's Prize?
    Chapter 4 Who Got Moseley’s Prize? Virginia Trimble1 and Vera V. Mainz*,2 1Department of Physics and Astronomy, University of California, Irvine, Irvine, California 92697-4575, United States 2Department of Chemistry, University of Illinois at Urbana-Champaign, Urbana, Illinois 61802, United States *E-mail: [email protected]. Henry Gwyn Jeffreys Moseley (1887-1915) made prompt and very skilled use of the then new technique of X-ray scattering by crystals (Bragg scattering) to solve several problems about the periodic table and atoms. He was nominated for both the chemistry and physics Nobel Prizes by Svante Arrhenius in 1915, but was dead at Gallipoli before the committees finished their deliberations. Instead, the 1917 physics prize (announced in 1918 and presented on 6 June 1920) went to Charles Glover Barkla (1877-1944) “for discovery of the Röntgen radiation of the elements.” This, and his discovery of X-ray polarization, were done with earlier techniques that he never gave up. Moseley’s contemporaries and later historians of science have written that he would have gone on to other major achievements and a Nobel Prize if he had lived. In contrast, after about 1916, Barkla moved well outside the scientific mainstream, clinging to upgrades of his older methods, denying the significance of the Bohr atom and quantization, and continuing to report evidence for what he called the J phenomenon. This chapter addresses the lives and scientific endeavors of Moseley and Barkla, something about the context in which they worked and their connections with other scientists, contemporary, earlier, and later. © 2017 American Chemical Society Introduction Henry Moseley’s (Figure 1) academic credentials consisted of a 1910 Oxford BA with first-class honors in Mathematical Moderations and a second in Natural Sciences (physics) and the MA that followed more or less automatically a few years later.

It turned the entire field of cosmology into a quantitative science. In it, Einstein described gravity as being a consequence of the geometry of the universe. Though this precise point is still unsettled, it is undeniable that dimensionality plays a role in modern physics and in gravity itself. Following quickly on the heels of Einstein’s discovery, physicists attempted to link gravity to the only other fundamental force of nature known at that time: electromagnetism.

  • Gentrification on the Planetary Urban Frontier: the Evolution of Turner’S Noösphere
    Gentrification on the Planetary Urban Frontier: The Evolution of Turner’s Noösphere Elvin Wyly Abstract: As capitalist urbanization evolves, so too does gentrification. Theories and experiences that have anchored the reference points of gentrification in the Global North for half a century are now rapidly evolving into more cosmopolitan, dynamic world urban systems of variegated gentrifications. These trends seem to promise a long-overdue postcolonial provincialization of the entrenched Global North bias of urban theory. Yet there is a jarring paradox between the material realities of some of the largest non-military urban displacements in human history in the Global South, alongside a growing reluctance to ‘impose’ Northern languages, theories, and politics of gentrification to understand these processes. In this paper, I negotiate this paradox through an engagement of several seemingly unrelated empirical trends and theoretical debates in urban studies and gentrification. My central argument is that interdependent yet partially autonomous developments in urban entrepreneurialism and transnational markets in labor, real estate, and education are transcending the dichotomy between gentrification in cities (the traditional focus of so much place-based research) versus gentrification as a dimension of planetary urbanization. Amidst the planetary technological transformations now celebrated as “cognitive capitalism” and a communications-consciousness “noösphere,” these developments are coalescing into a global, cosmopolitan, and multicultural
