Albert Abraham Michelson (1852-1931), the American optical physicist best known for his precise determination of the velocity of light and for his experiments concerning aether drift, is less often acknowledged as the creator of new spectroscopic instrumentation and new spectroscopies. He devised a new method of light analysis relying upon his favourite instrument – a particular configuration of optical interferometer – and published investigations of spectral line separation, Doppler-broadening and simple high-resolution spectra (1887-1898). Contemporaries did not pursue his (...) method. Michelson himself discarded the technique by the end of the decade, promoting a new device, the ‘echelon spectroscope’, as a superior instrument. High-resolution spectroscopy was taken up by others at the turn of the century using the echelon, Fabry-Pérot etalon and similar instruments. Michelson’s ‘Light Wave Analysis’ was largely forgotten, but was rediscovered c1950 and developed over the following three decades into a technique rechristened ‘Fourier transform spectroscopy’. This paper presents Michelson’s interferometric work as a continuum of personal interests and historical context as an example of 'research technology' and 'peripheral science'. (shrink)

This article discusses new material, published in volume 12 of the Collected Papers of Albert Einstein, that addresses Einstein’s knowledge of the Michelson–Morley experiment prior to 1905: in a lecture in Chicago in 1921, Einstein referred to the experiment, mentioned when he came upon it and hinted at its influence. Arguments are presented to explain the contrast with Einstein’s later pronouncements on the role of the experiment.

In lieu of an abstract, here is a brief excerpt of the content:John Dewey: The ChicagoYears GEORGE DYKHUIZEN DEWEYCAMETO CHICAGOin the summer of 1894 as head professor of philosophy at the University of Chicago and left in January, 1905, to become professor of philosophy at Columbia University. During his Chicago years, Dewey's interests led him not only into the field of philosophy but also into that of education, and in each of these areas he acquired a retmtation which placed him (...) among the top thinkers in the country. His work in philosophy resulted in his being acclaimed, along with Charles S. Peirce and William James, as one of the three great founders of American pragmatism, and his achievements in education led to his being regarded as one of the country's most outstanding educational thinkers and a prime mover in educational reform. The University of Chicago was only four years old when Dewey arrived there, but already it had attained a high standing among the universities of the country. The main reason for this was that the University had set out to be not simply another college but a university, like the universities in Europe and like Johns Hopkins and Clark universities in this country. This meant that the graduate schools of the University were to be stressed and that a large part of the faculty was to devote itself exclusively to graduate instruction and research. The type of faculty member the University looked for "must be a teacher, but first and foremost he must be a scholar, in love with learning, with a passion for research, an investigator who could produce, and if what he produced was worthy, would wish to publish." ~ In the four years since its founding, the University had assembled one of the most outstanding faculties in the country, a faculty which included: T. C. Chamberlin in astronomy, Rolin D. Salisburg in geology, Albert Michelson in physics, Jacques Loeb in biology, J. M. Coulter in botany, Thorsten Veblen in political economy, Albion Small in sociology, Paul Shorey in Greek, J. H. Breasted in Egyptology, and R. G. Moulton in English. When Dewey came to the University, therefore, as head of the Department of Philosophy, this meant that he was to teach mostly graduate students, do research, and have associations with some of the most brilliant scholars in the country. These features of the new position had appealed strongly to Dewey when he was considering the offer to 1T. W. Goodspeed, A History of the University of Chicago. The First Quarter (Chicago: 1916), 201. [227] 228 HISTORY OF PHILOSOPHY become professor of philosophy at Chicago and were among the decisive factors in bringing him to the University. William Rainey Harper, president of the University, was in large measure responsible for its early successes. "Those massive buildings, millions of money, thousands of scholars and scores of teachers," wrote one of his admirers, "are a monument to the foresight, nerve, and ceaseless activity of W. R. Harper, a veritable Napoleon in the educational field." 2 Born July 26, 1856, Harper was three years older than Dewey and every bit as precocious. He received his A.B. degree from Muskingum College when he was fourteen; he entered Yale as a graduate student when he was seventeen and got his Ph.D. degree from there at the age of nineteen. Upon receiving his doctorate, he began a career teaching Hebrew first at the Baptist Union Theological Seminary in Chicago and then, in 1886, at Yale. Harper wrote extensively on theological matters and his views prompted an attack on his orthodoxy in 1888. He weathered the storm, however, and throughout his life was a staunch defender of liberal theological thought. Harper had tremendous vitality and enthusiasm, and these qualities, along with his scholarship, led to his appointment as first president of the University when it was founded in 1890. Harper and Dewey were to have close associations on the administrative level, and though many of these were to be pleasant and cordial, others turned out to be not so harmonious and led eventually to Dewey's resignation from the University. Though Harper was particularly concerned that a strong department of philosophy be established at the University, up to the time of Dewey's... (shrink)

In 1786, Robert Blair, an unknown astronomer from Edinburgh, wrote a paper that would remain unpublished. In his manuscript, Blair gives a systematic treatment of the Newtonian kinematics of light, taking into account in the absolute space of Newton the motion of the light source, that of the observer, and the velocity of the corpuscles of light. Two years before, in the context of Newton's corpuscular theory of light, John Michell had pointed out that the velocity of light could be (...) measured with the help of refraction experiments. Blair went a step further and inferred the existence of what we now call the Doppler effect: a variation of refraction due to a relative motion of the source and the observer. Blair's proposal is at the roots of Arago's well‐known 1806–10 experiments on the velocity of light. In the context of the undulatory theory of light, Blair proposed an experiment to determine the absolute motion of the Earth, laying the bases for the famous experiment performed by Albert Michelson 100 years later. In fact, this manuscript contains the very questions of light relativity, the roots of spectroscopy, and addresses the very problems that would be hotly debated in the nineteenth century, only to be solved by Einstein in 1905.

The ArgumentMany inventors, engineers, and scientists think in verbal images. Elmer Sperry (1860–1930), a noted American inventor, was able to “operate” in his mind's eye the machines he was developing. For inventors, engineers, and experimental scientists, visualization is often followed by construction of a physical model of the invention, which can be an experimental apparatus. The model, or apparatus, is then tested in increasingly complex environments and changes are made in the physical artifact until it is ready to be used. (...) Examples of this process of development are Sperry's development of a ship stabilizer for the U.S. Navy and a revolving mirror to be used by Albert Michelson in the determination of the speed of light. Thomas Edison called experimentation his development of an invention through the building and testing of a series of models. So, both scientists and inventors experiment. They are not discovering the “secrets of nature”: they are observing how artifacts – their physical creations – behave. These physical models of thought reflect the characteristics of the tools with which they were made. They are socially constructed, as well. (shrink)

In 1905 Albert Einstein, in a paper entitled “On the Electrodynamics of Moving Bodies”, as a solution to the disagreement between classical mechanics and the results of the Michelson's experiment, who showed the invariance of the speed of light in vacuum measured in different inertial reference systems, developed the theory of special relativity. In this essay Einstein expounded a theory that, instead of introducing a privileged system, required the revision of the concepts of space and time of classical (...) physics. Combining the principle of Galilean relativity, according to which the laws of physics are invariant in all inertial reference systems, with the physics of electromagnetism, according to which the speed of light in a vacuum is constant, Einstein concluded that time is no more than a relative measure, namely that whenever we have to do with speed equal to or close to that of light, time is no longer a variable absolute and independent of the reference system adopted, but depends on the variable position. This is what Einstein shows through the critical examination of the concept of simultaneity. The abandonment of the traditional conception of space and time based on the idea of a spatial continuum flowing through a temporal continuum coherently leads to the assumption of a space-time continuum in which distances and time intervals vary with the changing the reference system, and together vary, of course, all other sizes to those connected.

The purpose of the study is to reveal the stages and content of experimental work on the spiritual and moral education of contract servicemen in the army environment. The article focuses on the presence of certain patterns in the assimilation of spiritual and moral qualities by contract servicemen, which formed the basis of the tested method of spiritual and moral education. The scientific novelty lies in the substantiation and experimental verification of the methodology for the spiritual and moral education of (...) contract servicemen in the socio-cultural army environment, based on the consistent formation of the ideals and values of their centuries-old domestic and military culture. As a result of the study, a positive dynamics of the level of formation of spiritual and moral qualities among contract servicemen at the control stage was revealed, which proves the effectiveness of the developed methodology.

The economic distinction between technological and market information offers a useful guide to the relationship between information and policy. The two types create different problems for markets and require different emphases in public policy, focusing on either the production or the distribution of information. The interaction of the two types creates familiar policy problems such as underinvestment in information, adverse selection and moral hazard. Indicators and other means of dealing with such problems constitute policies and demonstrate not only the importance (...) of information for policy but the necessity of policy for information.

Albert approaches critical rationalism as an alternative to other philosophical standpoints dominant in Germany: the conceptions of the Frankfurt School, hermeneutical thinking as represented by Gadamer, analytic philosophy, and logical empiricism. The author's purpose is to find a way out of the foundationalism of classical philosophy without falling back on the skeptical views so prevalent in today's philosophical thinking. Originally published in 1985. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from (...) the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

We develop a version of a direct perception account of emotion recognition on the basis of a metaphysical claim that emotions are individuated as patterns of characteristic features. On our account, emotion recognition relies on the same type of pattern recognition as is described for object recognition. The analogy allows us to distinguish two forms of directly perceiving emotions, namely perceiving an emotion in the absence of any top-down processes, and perceiving an emotion in a way that significantly involves some (...) top-down processes ; and, in addition, an inference-based evaluation of an emotion. Our model clarifies the epistemology of emotion recognition. (shrink)

A Nobel Prize winner, Dr. Szent-Györgyi concerns himself with the underlying forces and conditions that have prevented the realization of the higher possibilities of the American Dream, and, by extension, of all mankind. He addresses himself especially to the youth of the world in his attempt to show how man, the more he progresses technologically, seems the more to regress psychologically and socially, until he resembles his primate ancestors in a state of high schizophrenia. The fundamental question asked by this (...) book is: Why is it that most of the scientific research that is done to elevate human life serves in the end to destroy it? That this phenomenon exists is unarguable. How to alter it is the problem the author tackles. He finds the possibility, indeed the instrument of our survival, in our youth. Dr. Szent-Györgyi calls upon youth the world over to organize and exercise their power to create a new world. He implores them not to waste their energies in petulance and frustration-the world is ripe for the radical changes needed for man's survival, and for youth to fritter away their opportunity would be to compound the tragedy and seal the fate of mankind. Born into the fourth generation of a noted family of scientists in Hungary, Albert Szent-Györgyi decided at an early age to devote his life to biological research. As a medical student he required international recognition for his studies in microscopic anatomy. The First World War, which he spent in the service of the Austro-Hungarian army, caused a break in his career. After the war he left his devastated country to work for ten years in various countries, notably Germany, Holland, England and the United States. He then returned to his native Hungary to help rebuild science there. In 1937, he won the Nobel Prize for his studies on metabolism and for the discovery of ascorbic acid (Vitamin C). He soon found himself in conflict with the growing movement of Nazism, was arrested, escaped, and was hunted for years by the secret service of Hitler. After World War II, disappointed by Soviet colonialism and the terrorist methods of Stalin, he left Hungary and found refuge at the Marine Biological Laboratory of Woods Hole, Massachusetts.

« Qu'est-ce qu'un homme révolté? Un homme qui dit non. Mais s'il refuse, il ne renonce pas : c'est aussi un homme qui dit oui, dès son premier mouvement. »[réf. nécessaire] D'apparence, il existe une limite à la révolte. Cependant, la révolte est un droit. La révolte naît de la perte de patience. Elle est un mouvement et se situe donc dans l'agir. Elle se définit par le « Tout ou Rien », le « Tous ou Personne ». En premier, (...) elle soumet l'idée d'égalité : position d'égal à égal entre le maître et l'esclave. Mais le révolté finit par imposer cette égalité qui se traduit souvent par une inversion des rôles (dialectique hégélienne). Suivant le raisonnement de Scheler, l'homme révolté n'est pas l'homme du ressentiment, c'est-à-dire qu'il ne baigne ni dans la haine ni dans le mépris. La révolte enfante des valeurs. De fait, « pour être, l'homme doit se révolter ». La révolte extirpe l'homme de la solitude puisqu'elle est collective, c'est l'« aventure de tous ». Néanmoins, faire l'expérience de la révolte, c'est faire l'expérience de l'ascèse. Les mythes de Prométhée, d'Achille (avec Patrocle), d'OEdipe et d'Antigone, sont des archétypes de révoltes antiques au même titre que la révolte de Spartacus. La révolte est souvent légitime, elle est l'expression la plus pure de la liberté et semble revêtir le visage de l'espoir. De surcroît, la révolte impose une tension, elle refuse donc formellement le confort de la tyrannie ou de la servitude. Le révolutionnaire a la volonté de « transformer le monde » (Marx) alors que le révolté veut « changer la vie » (Rimbaud). (shrink)

The American Institute of certified public accountants (AICPA) has promulgated a Code of Professional Conduct , which has served as the primary ethical standard for public accountants in the United States for more than 20 years. It is now out of date and needs to be replaced with a code of ethics. Just as U.S. generally accepted accounting principles are being migrated toward “principles-based accounting” as part of a convergence with international financial reporting standards, a similar process needs to occur (...) with ethics. This article organizes the primary rules of the AICPA Code around five essential virtues: objectivity, integrity, inquisitiveness, loyalty, and trustworthiness. These virtues correspond to the general principles set forth in the Code of Ethics for Professional Accountants of the International Federation of Accountants (IFAC). From this virtue ethics perspective, various rules of the AICPA Code are critiqued as being inadequate at best, and poorly crafted at worst. The article concludes with the proposition that principles-based ethics serves the profession and the financial reporting process better than the current rules-based approach. (shrink)

A theory T is trustworthy iff, whenever a theory U is interpretable in T, then it is faithfully interpretable. In this paper we give a characterization of trustworthiness. We provide a simple proof of Friedman’s Theorem that finitely axiomatized, sequential, consistent theories are trustworthy. We provide an example of a theory whose schematic predicate logic is complete Π20.

Corporate codes of conduct frequently impose a duty of loyalty upon employees. l examine the notion of loyalty in general, and loyalty in the workplace in particular. I conclude that unless loyalty is defined and articulated in favor of a larger social project (rather than in favor of aperson, a set of ruIes, or other entity), efforts to encourage loyalty will be a source of epistemic distortion at best, and oppression at worst.

Pierce challenges the argument that economic sanctions are always morally preferable to the use of military force. He argues that such sanctions inflict suffering and physical harm on noncombatants and that small-scale military operations are sometimes preferable.
