History of Geology
FEBRUARY 2007 PRIMEFACT 563 (REPLACES MINFACT 60) History of geology Mineral Resources Early humans needed a knowledge of simple geology to enable them to select the most suitable rock types both for axe-heads and knives and for the ornamental stones they used in worship. In the Neolithic and Bronze Ages, about 5000 to 2500 BC, flint was mined in the areas which are now Belgium, Sweden, France, Portugal and Britain. While Stone Age cultures persisted in Britain until after 2000 BC, in the Middle East people began to mine useful minerals such as iron ore, tin, clay, gold and copper as early as 4000 BC. Smelting techniques were developed to make the manufacture of metal tools possible. Copper was probably the earliest metal to be smelted, that is, extracted from its ore by melting. Copper is obtained easily by reducing the green copper carbonate mineral malachite, itself regarded as a precious stone. From 4000 BC on, the use of clay for brick-making became widespread. The Reverend William Branwhite Clarke (1798-1878), smelting of iron ore for making of tools and the ‘father’ of geology in New South Wales weapons began in Asia Minor at about 1300 BC but did not become common in Western Europe until Aristotle believed volcanic eruptions and nearly 500 BC. earthquakes were caused by violent winds escaping from the interior of the earth. Since earlier writers had ascribed these phenomena to The classical period supernatural causes, Aristotle's belief was a By recognising important surface processes at marked step forward. Eratosthenes, a librarian at work, the Greek, Arabic and Roman civilisations Alexandria at about 200 BC, made surprisingly contributed to the growth of knowledge about the accurate measurements of the circumference of earth. -
Alexander Von Humboldt: Dilletante of Natural History Or Oracle of Modern Science?

Alexander von Humboldt: Dilletante of Natural History or Oracle of Modern Science? A.M. Celâl ¸Sengör ITU Eurasia Institute of Earth Sciences, Turkey ([email protected]) When the German satirist and journalist Alexander Moskowski interviewed Einstein in 1920 and implied that in Einstein’s Valhalla of scientific geniuses Alexander von Humboldt surely had a place, he was taken aback with the surprising denial: ‘At least Alexander von Humboldt I do not count among the geniuses. One has to realise that when we today look back upon the great discoverers, Humboldt hardly comes to mind.’ Writing to his friend Joseph Dalton Hooker, Darwin was more appreciative, but essentially made the same point: ‘I believe that you are fully right in calling Humboldt the greatest scientific traveller who ever lived. His Geology is funny stuff; but that merely means that he was not in advance of his age. I should say he was wonderful, more for his near approach to omniscience than for originality. Whether or not his position as a scientific man is as eminent as we think, you might truly call him the parent of a grand progeny of scientific travellers, who, taken together, have done much for science.’ Was Humboldt, the greatest geographer ever, only a wandering dilletante who amassed a vast amount of knowledge or did Darwin and Einstein miss something in him that made him a true oracle of modern science, a genius who saw farther than others in his time? Darwin did not live long enough to be able to read Suess’ Face of the Earth and Einstein probably never perused it as it was too far afield for him. -

THE BRITISH JOURNAL FOR THE HISTORY OF SCIENCE Vol. II t No. 39 (1978) < 221 > THE IMPORTANCE OF FRENCH TRANSFORMIST IDEAS FOR THE SECOND VOLUME OF LYELL'S PRINCIPLES OF GEOLOGY PIETRO CORSI* RECENTLY there has been considerable revaluation of the development of natural sciences in the early nineteenth century, dealing among other things with the works and ideas of Charles Lyell. The task of interpreting Lyell in balanced terms is extremely complex because his activities covered many fields of research, and because his views have been unwarrantably distorted in order to make him the precursor of various modern scientific positions. Martin Rudwick in particular has contributed several papers relating to Lyell's Principles of geology, and has repeatedly stressed the need for a comprehensive evaluation of Lyell's scientific proposals, and of his position in the culture of his time. -

Biblical Catastrophism and Geology
BIBLICAL CATASTROPHISM AND GEOLOGY HENRY M. MORRIS Professor of Civi I Engineering Virginia Polytechnic Institute Theories of catastrophism in geological interpretation are not new. Prior to the time of Sir Charles Lyell, scientists generally believed that most geological formations must be attributed to great physical catastrophes or revolutions. Lyell, however, taught that these phenomena could be explained by the ordinary processes of nature, acting over vast expanses of geological time. This is his "principle of uniformitarianism, II. now almost universally accepted as the foundation princ~ple of modern historical geology. Profoundly influenced by LyelPs theories, Charles Darwin soon published his theory of evolu tion by natural selection. The supposed paleontologi cal record of the evolutionary history of life on earth, together with the principle of uniformity, now constitutes the interpretive framework within which all data of historical geology are supposed to be explained. Furthermore, this phil osophy of evolutionary uniformitarianism now serves also as the interpretive framework in the social sciences and economi cs, and even in the study of religion itself. Thus a superstructure of gigantic size has been erected on the Lyellian-Darwinian foundation. However, catastrophism is not dead. The inadequacies of a thorough-going uniformitarianism have become increasingly obvious in recent years, and such quasi-catastrophist concepts as wan dering continents, shifting poles, slipping crusts, meteoritic and cometary collisions, etc., are appearing more and more frequently in geological literature. It is, in fact, generally recognized that even the ordinary fossiliferous deposits of the sedimentary rocks must often have at least a semi-catastrophist basis, since the process of fossilization usually requires rather rapid burial, under conditions seldom encountered in the modern world. -

MODERN SCIENCE AND THE SEARCH FOR TRUTH Brian Tonks—Department of Physics have pondered the question, “What is truth?” for many years. My I intellectual journey has convinced me that truth comes in many ways through a variety of sources. I began my schooling believing that scientists were searching for the truth, but my undergraduate training included classes in the history and philosophy of science that disillusioned me towards the scientific process. Then my service in the United States Navy showed me the practical utility of scientific principles, and my graduate studies provided real experience in how science really works. For five years I was involved in nearly all facets of the scientific process. My adult life spans the period of the Voyager missions to the outer planets, the Viking, Pathfinder, and Global Surveyor missions to Mars, and the Pioneer and Magellan missions to Venus. These missions demonstrated the power of scientific observation. Before Voyager, we knew little about the outer planets and even less about their satellites. Even in the largest ground-based telescopes, these appeared as mere pinpoints of light. Voyager revealed them as real worlds with actual, albeit bizarre, geology. Years of speculation were dispelled in a relative moment, reminding me of the Prophet Joseph Smith’s state- ment, “Could you gaze into heaven five minutes, you would know more than you would by reading all that was written on the subject” (History I have come full of the Church, 6:50). I have come full circle, believing today that science is an important source of truth. -
The Geohistorical Time Arrow: from Steno's Stratigraphic Principles To
JOURNAL OF GEOSCIENCE EDUCATION 62, 691–700 (2014) The Geohistorical Time Arrow: From Steno’s Stratigraphic Principles to Boltzmann’s Past Hypothesis Gadi Kravitz1,a ABSTRACT Geologists have always embraced the time arrow in order to reconstruct the past geology of Earth, thus turning geology into a historical science. The covert assumption regarding the direction of time from past to present appears in Nicolas Steno’s principles of stratigraphy. The intuitive–metaphysical nature of Steno’s assumption was based on a biblical narrative; therefore, he never attempted to justify it in any way. In this article, I intend to show that contrary to Steno’s principles, the theoretical status of modern geohistory is much better from a scientific point of view. The uniformity principle enables modern geohistory to establish the time arrow on the basis of the second law of thermodynamics, i.e., on a physical law, on the one hand, and on a historical law, on the other. In other words, we can say that modern actualism is based on the uniformity principle. This principle is essentially based on the principle of causality, which in turn obtains its justification from the second law of thermodynamics. I will argue that despite this advantage, the shadow that metaphysics has cast on geohistory has not disappeared completely, since the thermodynamic time arrow is based on a metaphysical assumption—Boltzmann’s past hypothesis. All professors engaged in geological education should know these philosophical–theoretical arguments and include them in the curriculum of studies dealing with the basic assumptions of geoscience in general and the uniformity principle and deep time in particular. -

Zeh The books in this collection are devoted to challenging and open problems at the forefront of modern science, including related philosophical debates. In contrast to typical research monographs, however, they strive to present their topics in a manner accessible also to scientifically literate non-specialists wishing to gain insight into the deeper implications and fascinating questions involved. Taken as a whole, the series reflects the need for a fundamental and interdisciplinary approach to modern science. Furthermore, it is intended to encourage active scientists in all areas to ponder over important and perhaps controversial issues beyond their own speciality. Extending from quantum physics and relativity to entropy, consciousness and complex systems – the Frontiers Collection will inspire readers to push back the frontiers of their own knowledge.
