The problem of scale pervades both the natural sciences and the vi sual arts. The earliest scientific discussions concentrate on visual per ception (much like today!) and occur in Euclid's (c. 300 B. C. ) Optics and Lucretius' (c. 100-55 B. C. ) On the Nature of the Universe. A very clear account in the spirit of modern "scale-space theory" is presented by Boscovitz (in 1758), with wide ranging applications to mathemat ics, physics and geography. Early applications occur in the cartographic problem of "generalization", the central idea being that a map in order to be useful has to be a "generalized" (coarse grained) representation of the actual terrain (Miller and Voskuil 1964). Broadening the scope asks for progressive summarizing. Very much the same problem occurs in the (realistic) artistic rendering of scenes. Artistic generalization has been analyzed in surprising detail by John Ruskin (in his Modern Painters), who even describes some of the more intricate generic "scale-space sin gularities" in detail: Where the ancients considered only the merging of blobs under blurring, Ruskin discusses the case where a blob splits off another one when the resolution is decreased, a case that has given rise to confusion even in the modern literature.
Europe, 1940. Nazi forces sweep across the continent, with A British invasion likely only weeks away. Never before has a resistance movement been so crucial to the war effort. In this definitive appraisal of Anglo-Norwegian cooperation in the Second World War, Tony Insall reveals how some of the most striking successes of the Norwegian resistance were the reports produced by the heroic SIS agents living in the country's desolate wilderness. Their coast-watching intelligence highlighted the movements of the German fleet and led to counter-strikes which sank many enemy ships – most notably the Tirpitz in November 1944. Using previously unpublished archival material from London, Oslo and Moscow, Insall explores how SIS and SOE worked effectively with their Norwegian counterparts to produce some of the most remarkable achievements of the Second World War.
This work talks about the taking in and use of food and other nourishing material by the body. Nutrition is a 3-part process. First, food or drink is consumed. Second, the body breaks down the food or drink into nutrients. Third, the nutrients travel through the bloodstream to different parts of the body where they are used as fuel and for many other purposes. To give the body proper nutrition, a person has to eat and drink enough of the foods that contain key nutrients. This new book examines new research in this field which is belatedly receiving the proper attention.
