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.     

Smell: A Challenge to Interdisciplinary Science

Abstract

The sense of smell remains an intractable problem and a challenge to interdisciplinary sciences. Not only are there no primary odors or periodic table of scents but there are no satisfactory numerical identifications by visual, auditory or somesthetic methods of measurement. A particle-wave relation may exist to reconcile the correlation of many odors with infrared spectra, but the vibrational theory of smell is currently out of fashion. Structure-activity relationships have been studied in human olfactory processes and have yielded perfume compounds of great value to commerce. Research on pheromones is intense to control insects, and the further study of human pheromones may even reveal an unsuspected communications system. At present, interdisciplinary sciences can well be guided by the artist-perfumer for what seems a millennium of research in molecular biology.     

Science and Theology Diverse Resolutions of an Interdisciplinary Gap by the New Priesthood of Science

Abstract

In an age where the trend towards secularization has been slowed down, new religions and ideological movements are competing with the more traditional positions to be found in society. Those who are anxious to justify their own particular position share only one criterion for comparison with those holding other positions: a belief in the epistemological efficacy of science. A new priesthood of scientist has emerged to offer justification in the name of science for a variety of ideological positions and to explain to a bewildered public what the real relationship is between the various disciplines of science and those of theology or moral and political philosophy. This paper describes the variety of positions taken up by the new priesthood, typifying these as Fundamentalism, Orthodoxy; Liberalism, Modernism, Agnosticism and Atheism.     

Science,Technology and Constitutional Rights: An Interdisciplinary Forecast for the US Congress

Abstract

In honor of the bicentennial of the United States Constitution, a Congressional agency undertook an interdisciplinary analysis of the implications of new and emerging science-based technologies for constitutionally protected civil rights and liberties. Four areas of scientific research and development were identified as most likely to give rise to significantly new technological capabilities. Some of these could challenge established assumptions about individual responsibility, civil liberties, and the powers of government: information science, molecular biology, materials science, and social science, particularly as they find applications in communications and publishing, criminal justice, medicine, public health, and bioengineering. Constitutional precedents related to freedom of the press, open scientific communications, the rights of those accused or convicted of crime, due process, equal protection of laws, and individual privacy will have to be re-examined. Science is offering individuals new choices and forcing them to make new decisions, even as it brings into question some assumptions about free will and accountability.     

Eco-Archaeometry: Interdisciplinary Applications in Egypt

Abstract

One of the problems currently faced by modern society is the worldwide catastrophic deterioration of archaeological and cultural sites directly exposed to the action of the environment. Frequently, it has proved difficult to identify the processes responsible for these deteriorations, which are often the result of an abrupt change in site specific environmental conditions. To understand them a broad interdisciplinary approach is needed, and consequently, a substantial input from several disciplines, such as archaeology and archaeometric, environmental and conservation sciences, is necessary. Such interaction is particularly necessary on a basic research level, and can best be achieved if the relevant disciplines are drawn together a priori on equal footing into a complementary effort in eco-archaeometry. The primary goal of eco-archaeometry is to identify and quantify physicochemical processes which cause the deterioration of ancient cultural patrimony. Its findings are essential prerequisites for the development of optimum, safe methods for conservation and preservation of ancient monuments. Some examples of the eco-archaeometric approach in Egypt are summarised and it is demonstrated that without an interdisciplinary approach such studies would not have been successful.     

Darwin on stage: evolutionary theory in the theatre

Abstract

The chirality of living matter, and of its chemical processes, is reviewed. It is argued that the development of chiral self-replicating systems from nonliving maner is perfectly possible from precursors tbat are available only in racemic form, and that external chiral influences are unnecessary for this development. Minimal conditions for the nonbiotic development of a self-replicating molecular species are discussed, and it is proposed that this development could occur in a small self-contained aqueous system exposed to sunlight and incorporating a limited supply of simple organic precursor molecules, provided that polyphosphates are continuously being synthesised photochemically and that a catalyst for phosphate transfer is continuously available. The importance of hydrolysis, at a rate comparable to synthesis, is emphasised.     

捕鱼能手 鸬鹚

<正>西湖是人间天堂,也是鸟类乐园。每年冬天,大批鸬鹚从北方飞来越冬,西湖成为游人观赏鸬鹚、鸟人拍摄鸬鹚的好去处。我跻身在这人群中,欣赏、拍摄并渐渐研究起来。当我每拍一种鸟并探寻它的历史背景时,激动的心久久不能平静,以至于有"百种鸟有百种故事"的赞叹。
