Revolutions in music and physics, 1900–30

Abstract

The period 1900 to 1930 saw fundamental changes in the basic laws of physics. The discoveries of the special and general theories of relativity and those of quanta and quantum mechanics transformed profoundly physicists' understanding of the nature of space and time, as well as the fundamentals of physics at the atomic level, which have no counterpart in classical physics. Almost coincidentally, major changes took place in the processes of musical composition – that same period seeing the development of atonality, the liberation of rhythm, and twelve-tone music. This essay reviews in non-technical terms the profound changes in the thinking of physicists and compares the intellectual struggles involved with the extraordinary parallel changes in the approaches of composers to musical composition. No causal connection is suggested, but the common theme of the processes of innovation and creativity within very strict sets of rules in both physics and music is emphasised.     

Composing Einstein: exploring the kinship of art and science

Abstract

The work Albert Einstein published in 1905 led to a revolution in physics and the way nature is explained. At the same time, his physics touches on profound existential questions which are also dwelt upon in the arts. This article addresses the relatedness of music and physics, art and science. The point of departure is my composition The Einstein Resoundings, and how writing it refined my sensitivity to the deeper layers of creative effort. I discuss points of contact between the spheres of music and physics: the phenomenon of quantum leaps, continuous and discontinuous structures in tone and atom, and the role of continuity and discontinuity in the act of creation. My reflection on the kinship of art and science is based on the notion of complementarities. This allows a double perspective on art and science as different in regard to activity and language, but similar in regard to their mutually complementing characters.     

Book reviews

Abstract

Some of the highlights and disappointment in low-temperature physics and technology are presented. Emphasis is on concepts and trends rather than on rigorous and complete treatment. Cooling methods and the properties of matter at low temperature are discussed, both from a purely scientific and an applied point of view, with some emphasis on superconductivity.     

In Praise of Interdisciplinary Archaeology

Abstract

The study of instabilities has long been a central aspect of physical theories and experimental investigation. Chaotic behaviour is a more recently recognized general feature of physical systems, expecially hard-driven dynamical systems. This review describes physical models illustrating these phenomena and seeks to indicate their application to understanding a variety of problems outside physics. Thus, the occurrence of instabilities is advanced as the reason why different sciences have developed independently, and why their results cannot be regarded as deducible from the fundamental laws of physics. In particular, sociology and political science are seen as attempting to deal with extreme cases of chaotic behaviour resulting from widespread instability. Finally, a simple physical model of stop-go oscillations is described, and interpreted as a warning against over-optimistic expectations that modern attempts at participatory democracy are compatible with a stable society.     

Ivory towers? The commercial activity of British professors of engineering and physics, 1880–1914

Abstract

The involvement of British academic scientists in commercial work has been often discussed by historians of science and technology. However a systematic study of this activity is still lacking. Focussing on the period 1880 to 1914, I examine the engagement in consulting, patenting and entrepreneurial initiatives of a segment of that community, namely engineering and physics professors. I discuss the institutional context in which it occurred and their motivations. The survey highlights that the majority of the engineering professors examined were involved in consulting and patenting, and a significant number of them pursued also entrepreneurial activities. As for the physics professors, only a few followed the example of their engineering colleagues, but did so vigorously. I argue that far from being reluctantly brought into the market for knowledge, the engineering as well as the physics professors who engaged these extra-academic activities eagerly sought to partake in the commercialization of the products of their scientific work.     

Interdisciplinarity as critical Inquiry: Visualizing the Art/Bioscience interface

Abstract

Much˙ of the physiology of human cells is controlled at their surfaces. Our knowledge is based on an interdisciplinar:r approach involving research in subject areas ranging from physics to medicine. In this review, the structure and function of cell surfaces, their turnover and their role in cell division is described. The concept of cell sulrface diseases is introduced and discussed. The conclusion is reached that further knowledge of cell surfaces will lead to better treatment of many common diseases.     

Symmetry and symmetry breaking in nature

Abstract

According to Hermann Weyl and in the words of Richard P. Feynman, an object is symmetric if one can subject it to a certain operation and it appears exactly the same after the operation. This paper generalises this definition of symmetry of objects in space to symmetries of the laws of nature. Consequences of the laws of physics that follow from their symmetries are derived and compared with the experimental evidence. It is pointed out that unobservability is at the root of all symmetries in the natural sciences. Symmetries of the laws of physics can be hidden by asymmetries of realisable states that follow from a lack of symmetry in the ground state of the system. If that is the case, transitions from states that share the symmetries of the laws, to states in the neighbourhood of the ground state that do not, involve symmetry breaking through self-organisation.     

The Rolt Memorial Lecture, 1978 Sir Humphry Davy: His Life and Work

Abstract

Sir Humphry Davy, a largely self-taught genius of humble birth, made major contributions to the development of chemistry, physics, geology and natural history in the early nineteenth century. Much of his research was directly beneficial to various industries principally agriculture, mining and metallurgy, electro-chemicals and leather processing. He is best remembered for his miners' safety lamp and the story of its development forms the core of this paper.     

Albert Einstein,Physicist (1879–1955)

Abstract

Einstein's ideas changed man's thoughts about the totality of physics. These ideas were so fundamental for human thought that Einstein belongs to all the sciences and to all cultures. If ever there was a scientist whose centenary ought to be commemorated in an interdisciplinary journal, Einstein would be that one. This is because of the all-pervading influence of the revolution in physics in which Einstein played so paramount a part. Here we look back to what one man was able to contribute to transforming everyman's thought about the physical world. For the most part the lasting consequences are evident and well-known. Nevertheless, we have to observe that in some respect – not necessarily those emphasized by Einstein – the implications are still scarcely apprehended.     

Endorheic currents in ecology: an example of the effects from scientific specialization and interdisciplinary isolation

ABSTRACT

Mainstream ecological thought is explored in three sections: (i) Epistemological traits. Given the typical scientific development and the necessity of preserving our intellectual heritage, the conservatism outlined in (i) is cyclical, so its stages are graphically summarized. (ii) Methodological benchmarks antithetically derived from (i), in order to get faster advancement consistent with the growing environmental challenges which spur ecological development. (iii) The renaissance of an old paradigm. This section exposes the misunderstanding of the physical concept of equilibrium by the mainstream ecological thought; this explains its current state. Consequently, section (iii) also summarizes the evolution of a recent set of proposals (organic biophysics of ecosystems) that rescues the foundational paradigm of ecosystem ecology based on physics, neglected by the mainstream thought before producing its most valuable results. We highlight that the main problems emerge from the weakness of integration between ecology, physics and epistemology, and spurious links between ecology and neoclassical economics.     

A Farewell to Alms: A Brief Economic History of the World

Abstract

The reasons for the lack of communication between economists and econophysicists are clarified by giving an outline of the methodological differences between economics and econophysics, which has emerged as a new field of research over the last decade. Theorists working in econophysics see economic and financial phenomena through the ‘lens’ of statistical physics. So far, there has been no real dialogue between economists and econophysicists because both communities adhere to their own methodological precepts.     

Evolution as context-driven actualisation of potential: toward an interdisciplinary theory of change of state

Abstract

It is increasingly evident that there is more to biological evolution than natural selection; moreover, the concept of evolution is not limited to biology. We propose an integrative framework for characterising how entities evolve, in which evolution is viewed as a process of context-driven actualisation of potential (CAP). Processes of change differ according to the degree of non-determinism, and the degree to which they are sensitive to, internalise and depend upon a particular context. The approach enables us to embed phenomena across disciplines into a broad conceptual framework. We give examples of insights into physics, biology, culture and cognition that derive from this unifying framework.     

Engineering as a Source of Scientific Ideas

Abstract

Engineering has discovered some laws of nature as limits to what can be done, from which have developed the sciences of thermodynamics, information theory and cybernetics. Considered as a science, engineering lies between physics and biology, because its machines have physical structures and properties but biological organizations and functions. The old idea of the living body as an engine retains its power in modern biology; and the reconsideration of various natural non-biological processes in terms of engineering and biological concept reveals inadequacies in modern physical theory.     

Erasmus Darwin: Master of Interdisciplinary Science

Abstract

Dr Erasmus Darwin (1731–1802) was by profession a physician, at Lichfield and later Derby, and was widely regarded as the leading doctor in Britain, author of the massive treatise Zoonomia (1794–6). His many original contributions to science cover a wide range of disciplines, including physics, chemistry, geology, meteorology, plant growth and nutrition and evolutionary biology. He was a prolific inventor, a close friend of Boulton and Watt, and a leading spirit in the ‘Lunar Society’ of Birmingham. In the 1790s he became the most famous poet of the day with his Botanic Garden, which greatly influenced Coleridge, Wordsworth and others.     

The art of science at Fermi National Accelerator Laboratory: The rhetoric of aesthetics and humanism in the national laboratory system in the late 1960s

This paper examines how rhetoric shaped the early history of the National Accelerator Laboratory. In a situation defined by a contentious site search and shrinking budgets for research, Robert Wilson crafted an institutional identity for the NAL that emphasized both aesthetic and scientific experience. The paper addresses the circumstances of the laboratory's founding, the "audiences" important to its success, and the ways in which the physical environment and management structure--framed by Wilson's vision of a scientific utopia--reorganized existing perceptions of physics within a humanistic framework intended to distinguish the NAL from its predecessors in the National Laboratory system.     

Adhesion An Interdisciplinary Science

Abstract

The interdisciplinary science of adhesion is built upon contributions from the classical branches of science: chemistry, physics and mathematics, and some of their more specialized subdivisions such as polymer chemistry, surface chemistry, rheology and continuum mechanics. An historical review of the development of adhesive technology stresses the role of polymer chemistry in the advances made in modern adhesion technology, but many other disciplines have contributed. Their roles are discussed from the point of view of adhesion theories that are biased toward one discipline or another. Such bias can lead to fallacy. Challenging adhesion problems still exist and their solution will involve other disciplines, like biology and medicine.     

Electrical instruments in 19th century France,between makers and users

Abstract

Having quickly described new historiographical approaches to scientific instruments, this paper explores some characteristics of the evolution of the relationship between scientific instrument makers and French physicists in the 19th century. Artisans without a scientific culture at the dawn of the century, a certain number of instrument makers were integrated into the scientific community by its end, sharing their practices and their values. These builders served as mediators between different physicists, between physicists and members of other disciplines like physiology and, finally, between savants and the world of technology (telegraphy and then industrial electricity). Symmetrically, a significant number of French physicists left mathematical physics for a physics based on instruments and their development. The emergence, extension, and eventual disappearance of the different contexts of use of an instrument (amateurs, public performances, teaching, research, medicine, telegraphy, industry, etc) illustrate both the boundary crossings between these different domains and the major role that use played in successive reconfigurations of instruments.     

Depleted uranium

Abstract

This paper presents a quantitative and qualitative biographical analysis of Nobel prize laureates in physics over the first hundred years of the award. For the quantitative analysis a set of data has been collected from the laureates' biographies, which is used to characterise their education and professional careers. Such an analysis of the biographies of Nobel laureates provides interesting information about the structure and politics of scientific research. Statistical evaluation of the data is of interest from the viewpoint of research and educational policy, and may also be useful for further science historical analysis. In the qualitative analysis, special features of the laureates' biographies are highlighted, with the aim of providing insights into their scientific motivations and the development of their careers.     

The Acoustics of Stringed Musical Instruments

Abstract

Attempts to understand the action of musical instruments at a level having some impact on the problem of musicians and instrument maker must face formidable unsolved problems in psychoacoustics as well as in classical physics. This review outline what is known about the physical properties of stringed instruments, with emphasis on the violin family, and tries to identify basic outstanding problem where progress may be hoped for within the next decade. One such area is assessment of the widely used simplest idealization of violin behaviour in which the driving at the bridge is assumed to be transverse, and the body is modelled as a 'black box' with one input and one output. Other major problem include the physical nature and psychoacoustical relevance of complex fine detail in the behaviour of the bowed string.     

Good Health Communications: An Essential Part of Effective Health Care

Abstract

This paper presents an overview of some recent applications of methods of statistical physics to financial problems such as stock market behaviour and crashes. This field of research has seen intensive developments over the last ten years and is today known as econophysics. The first section of the paper oers a review of the main directions of research in experimental, theoretical, and applied econophysics. A second section then introduces a case study of physical modelling of a financial event, namely a stock market crash seen as a higher order phase transition. The model used is the Ising model in Bethe–Peierls (‘quasi chemical’) approximation. In spite of its minimal character, the model exhibits a statistical pattern of stock market prices consistent with that observed empirically.
