William Smith's 1815 Map of the Geology of England and Wales was a ground‐breaking achievement that changed the understanding of geology forever. However, perhaps Smith's greatest contribution to science lay in nurturing the talent of his orphaned nephew, John Phillips, who grew up to become one of the most versatile and distinguished geologists and polymaths of the nineteenth century.  相似文献

The equation describing the conduction of heat in solids has, over the past two centuries, proved to be a powerful tool for analyzing the dynamic motion of heat as well as for solving an enormous array of diffusion-type problems in physical sciences, biological sciences, earth sciences, and social sciences. This equation was formulated at the beginning of the nineteenth century by one of the most gifted scholars of modern science, Joseph Fourier of France. A study of the historical context in which Fourier made his remarkable contribution and the subsequent impact his work has had on the development of modern science is as fascinating as it is educational. This paper is an attempt to present a picture of how certain ideas initially led to Fourier’s development of the heat equation and how, subsequently, Fourier’s work directly influenced and inspired others to use the heat diffusion model to describe other dynamic physical systems. Conversely, others concerned with the study of random processes found that the equations governing such random processes reduced, in the limit, to Fourier’s equation of heat diffusion. In the process of developing the flow of ideas, the paper also presents, to the extent possible, an account of the history and personalities involved.

Al Gore’s movie An Inconvenient Truth gives a variety of unusually biased interpretations of the state of climate science and global warming theory. These cover a wide range of natural events and processes which could potentially be impacted by global warming, but which the movie misrepresents as clear examples of the human influence on climate. A few examples include the mixing up of cause and effect in his graphical portrayal of temperature and carbon dioxide variations over hundreds of thousands of years; the repeated depiction of ice calving from glaciers as a sign of global warming; the implication that Hurricane Katrina was the fault of humans; and the particularly extreme view that the Greenland ice sheet will melt, flooding coastal cities worldwide. Ultimately, all of these are related to the widespread perception that scientists have uniquely tied global warming to anthropogenic greenhouse gas emissions. The real inconvenient truth is that science has no idea how much of recent warming is natural versus the result of human activities.  相似文献

In 1859, in his great work On the Origin of Species, Darwin repeatedly raised what he regarded to be the most serious problem facing his theory of evolution – the lack of fossils predating the rise of shelly invertebrates that marks the beginning of the Cambrian Period of geological time (550 Ma), an “inexplicable” absence that could be “truly urged as a valid argument” against his all-embracing synthesis. This missing early fossil record posed a major dilemma, for Darwin's theory demanded firm linkage from the less advanced to the more evolved, from primitive microbes to protozoans to the rich faunas of the basal Phanerozoic for which no fossil evidence was known. For more than 100 years, the history of Precambrian life stood out as one of the greatest unsolved problems in natural science. In recent decades, however, understanding of life's early evolution has changed markedly as the documented fossil record has been extended seven-fold to some 3500 Ma, an age more than three-quarters that of the planet. This long-sought solution to Darwin's dilemma was set in motion by a small vanguard of workers who blazed the trail in the 1950s and 1960s, just as their course was charted by a few prescient pioneers of the previous century. All workers today, including the 28 participants in the recently held World Summit on Ancient Microscopic Fossils, have roots that can be traced to the pathfinders of a half-century ago.  相似文献

文章介绍李希霍芬(1833~1905,F.vonRichthofen)对地貌学建立的重要贡献及这门学科自此以后在德国的理论进展;论证了在过去的100年中,在不同时期都有德国杰出的科学工作者叙述对李希霍芬著作的认同和赞赏。总体上来讲,很多人都同意称李希霍芬为关于地形和景观科学的“地貌学之父”。在A.洪堡(A.Humboldt)和C.李特尔(C.Ritter)早期概念的基础上,李希霍芬使地理学变成一门研究人类生存空间的自然科学。尽管在李希霍芬之后所发展起来的气候地貌学和地生态学的重要性是不可低估的,但直到今天李希霍芬所开展的与地质学有紧密联系的地貌学的分支仍具有活力。  相似文献

Ravine and gully erosion affects 1% of India's land area. Zones of severe ravine trenching are found along the margins of the Gangetic Basin and in the semi-arid northwest. Ravine reclamation is currently rated as a high national priority, and India has the Third World's leading soil conservation movement. This paper reviews the technical contributions made to the study of ravine origins and genesis by government soil conservation research workers in the light of the dissident views expressed by academic geoscientists. It also reviews the soil conservation establishment's major contributions to cost-effective ravine reclamation planning. However, it is emphasised that while great advances have been made towards technological remedies for ravine erosion, relatively little has been accomplished in the realm of social science. Successful ravine reclamation requires the support and involvement of the local cultivator and local community and, probably, reform of local land tenure and social arrangements. Towards this end, much experience has been accumulated in non-government circles through the activities of Gandhian sarvodaya groups. It is recommended that their ideas and methods are integrated into ravine reclamation activities.  相似文献

The tribute to Mikhail V. Lomonosov on the occasion of his 250th anniversary of his birth enables better students of the history of geological science to identify the obvious confusion and glaring flaws in this overstated presentation of Lomonosov as the father of geology. Perhaps it will stimulate interest in Lomonosov's On Terrestrial Strata, published in 1763. The article contains evidences of overwhelming self-pride of the Communists in the fact that Lomonosov was Russian, but in identifying him as somehow linked with progressive Communism leaves one to wonder.--B. N. Cooper.  相似文献

Despite the widely acknowledged threat posed by invasive species in coastal estuaries, there are substantial gaps at the intersection of science and policy that are impeding invasive species management. In the face of pressing management needs in coastal and estuarine environments, we advocate that introduced species should receive the kind of management effort dedicated, for example, to reducing pollution. We support our argument with some examples of economic costs of estuarine and coastal introduced species and a summary of recent evidence for the ecological costs. We highlight some of the issues that either thwart or facilitate the successful marriage between science and management of introduced species, including the regulatory framework for management. We use the available information on coastal eradication programs, including case histories of the programs for Caulerpa taxifolia and Spartina alterniflora (and hybrids) in the western USA, to indicate the feasibility of managing introduced species and to help point out how management and science can improve the outcome. We close with a research agenda that focuses primarily on science that will really assist with invasive species management and reflects our own experience and the opinions of managers directly involved with this issue.  相似文献

Tamura et al. (2018) refined our understanding of formative processes that have resulted in a series of coarse‐sand beach ridges at Cowley Beach in north‐eastern Australia. Nott (2018) claimed that there are several shortcomings in the findings Tamura et al. (2018) presented. However, his criticism mostly derived from his misunderstanding of the data and discussion presented in Tamura et al. (2018), which thus should be clarified here. This reply also reiterates how his method for estimating the magnitude of past tropical cyclones from beach ridges is inconsistent with our observations of beach morphology and beach‐ridge formative processes.  相似文献

At the advent of the twentieth century, geologists believed that folded continental mountain chains like the Alps were due to horizontal compression, resulting from contractions of the Earth’s crust as it cooled. In 1918, Albert Heim defended this point of view and illustrated it with a geological section across Switzerland. In 1915, however, and in short notes as early as 1912, Alfred Wegener in Die Entstehung der Kontinente und Ozeane (The Origin of Continents and Oceans) proposed that mountains were the result of collisions between light continents drifting and floating on denser formations of the Earth’s interior, also present at the bottom of the oceans. Before this (1906), Otto Ampferer had already proposed the association of folds with active movements of material inside the Earth. Wegener used numerous morphological, geological, and gravimetric data to justify his theory. He was innovative in his successful use of paleogeographic and paleoclimatologic reconstitutions. Although very popular, his theory only received reserved approval from the active scientific community. Alpine geologists found it too audacious and too far removed from the field data. In the first critical analysis written in French (1922), Elie Gagnebin welcomed it as a working hypothesis, but was very reserved regarding the arguments of a geophysicist who, in his opinion, was not sufficiently versed in structural geology. In contrast, Emile Argand integrated Wegener’s theory into his conception of the evolution of the Alps already in 1916. At that time, he judged the Alpine orogeny to have been the result of permanent compression and proposed that its whole history had been dominated by what he called embryonic tectonics, a compressional concept which he illustrated so admirably that it had an incomparable and lasting success. However, he himself abandoned it in his major work, La Tectonique de l’Asie (The Tectonics of Asia), in favour of an evolution that first originated in an extension regime, finally leading to the splitting of the continental crust, with local emergence of basic rocks, constituting the bottom of new oceanic floors. It is at the slope of these continental margins, and at their foot, that geosynclines are formed by the large accumulation of sediments transported by submarine slumping. During the following compressive stage, slices of basic ocean floor are transported upwards between overlapping continental masses, forming extensive ophiolitic zones. Although admired for his enormous accomplishment, La Tectonique de l’Asie remained ignored for its most innovative propositions, which clearly foreshadow plate tectonics. After this work, Argand practically abandoned geology. His last publication (1934), Guide géologique de la Suisse: la zone pennique (Geological Guide to Switzerland: the Pennine Zone), revived his argument of the early evolution of the geosyncline in a context of extension, followed by thrusts involving the ocean floor. Unfortunately, the concept had no greater success than at its first appearance.  相似文献

This tribute praises Lomonosov for his purported employment of the dialectic concept to the evolution of the earth. The claim that Lomonosov's interpretations of the earth are materialistic is absolutely true, as are all other scientific interpretations. Whether he is the father of materialism in Russian science is of little importance because all sound science is materialistic.

Twelve partly substantiated claims about Lomonosov's work are summarized. The statements that he first applied historical analysis to explain geologic phenomena and that he established the principle of actualism 70 years before LyeII should be brought to the attention of those unfamiliar with the contributions of the great Russian scientist. The tribute contains a good bibliography.--B. N. Cooper.  相似文献

At a time when human geography–in its search for general and systemic laws–was often seduced by different kinds of determinism, Jean Gottmann developed his theoretical model in order to explain the political partitioning of geographical space. This model, shaped by the study of the classics in political philosophy, makes explicit reference to human psychology, and is based on a few fundamental concepts: cloisonnement (partitioning), circulation (movement), carrefour (crossroad) and iconographie (iconography). This paper presents the above mentioned concepts through a chronological analysis of their formulation in different chapters of Gottmann's bibliography, in order to reconstruct the genesis and evolution of his model. In the conclusions a few questions are presented, that suggest how Gottmann's model could still be usefully applied to contemporary human and political geography.  相似文献
