  • Although in some respects more technical in their subjects and style than Darwin's "Journal," the books here reprinted will never lose their value and interest for the originality of the observations they contain. Many parts of them are admirably adapted for giving an insight into problems regarding the structure and changes of the earth's surface, and in fact they form a charming introduction to physical geology and physiography in their application to special domains.

  • The term engineering itself has a much more recent etymology, deriving from the word engineer, which itself dates back to 1325, when an engine'er (literally, one who operates an engine) originally referred to "a constructor of military engines."[4] In this context, now obsolete, an "engine" referred to a military machine, i.e., a mechanical contraption used in war (for example, a catapult). Notable exceptions of the obsolete usage which have survived to the present day are military engineering corps, e.g., the U.S. Army Corps of Engineers....

  • The internal combustion engine was originally selected for the automobile due to its flexibility over a wide range of speeds. Also, the power developed for a given weight engine was reasonable; it could be produced by economical mass-production methods; and it used a readily available, moderately priced fuel - petrol.

  • Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions.

  • Understanding the origins of humanity has long been one of our foremost intellectual pursuits, and one that greatly interests the general public as evidenced by museum attendance and by numerous media productions and general interest publications. Progress toward an improved understanding of our heritage is a continuing challenge for the scientific community, requiring advances in a range of disciplines that include archaeology, anthropology, geology, biology, oceanography, and genetics, and particularly research advances in areas where two or more of these fields intersect.

  • Or consider what our great grandfathers thought about the mountains, which we now consider so scenic. 4 They were 'monstrous excrescences of nature'. 5 God originally made the world a smooth sphere happily habitable for the original humans; but, alas, humans sinned, and the earth was warped in punishment. Thomas Burnet is repelled by these 'ruines of a broken World', 'wild, vast and indigested heaps of Stones and Earth' that resulted when 'con- fusion came into Nature'. 6 John Donne called them 'warts, and pock-holes in the face of th'earth'. 7 Now we know better.

  • Coal formation has been described as “an inefficiency in the carbon cycle,” (Barghoorn, 1952) when carbon from plants remains in terrestrial sediments and is not recycled to the atmosphere (Figure 1.1.1). Coal is, by definition, a readily combustible rock containing more than 50% by weight and 70% by volume of carbonaceous material (Schopf, 1966). Another definition describes coal as a combustible solid, usually stratified, which originated from the accumulation, burial, and compaction of partially decomposed vegetation in previous geologic ages (Hendricks, 1945)....

  • The Japanese, looking as they do for essences in landscapes, enjoy the transi- ence of nature; how the cherry blossoms are here today, gone tomorrow, and will return again next year, and the next after that. Everyone who constitutes a landscape must also cope on that landscape, and in that struggle everyone who beholds landscapes can become sensitive to what is going on as the world continues on, even though they may not know its deep history in geological and evolutionary time. They know context, if not origins.
