Extrait : Alexandre Grothendieck est un mathématicien apatride, ayant passé la majorité de sa vie en France, né le 28 mars 1928 à Berlin (Allemagne). Lauréat de la médaille Fields en 1966, refondateur de la géométrie algébrique, il est considéré comme l'un des plus grands mathématiciens du siècle. Sacha Schapiro, son père, est un anarchiste militant né près de Bryansk, ville située en Ukraine peuplée de Juifs hassidim. Après avoir passé dix ans en prison pour sa participation à plusieurs soulèvements anti-tsaristes, il rejoint Berlin où il rencontre sa femme, Hanka Grothendieck, protestante hambourgeoise qui partage l'idéal anarchiste. Elle est alors mariée à Johannes Raddatz : le fils de Sacha et Hanka s'appelle tout d'abord Alexander Raddatz. Hanka divorce en 1929, Sacha reconnaît le petit Alexander mais n'épouse pas Hanka. Hanka et Sacha fréquentent les cercles radicaux. En 1933, la m...http://booksllc.net/?l=fr ... Read more

Source: Wikipedia. Free updates online. Not illustrated. Excerpt: Jean Léopold Nicolas Frédéric Cuvier (August 23, 1769 May 13, 1832), known as Georges Cuvier, was a French naturalist and zoologist. Cuvier was a major figure in natural sciences research in the early 19th century, and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. He is well known for establishing extinction as a fact, being the most influential proponent of catastrophism in geology in the early 19th century, and opposing the gradualistic evolutionary theories of Lamarck and Geoffroy Saint-Hilaire. His most famous work is the Le Règne Animal (1817; English: The Animal Kingdom). In 1819, he was created a peer for the life in honor of his scientific contributions. Thereafter he was known as Baron Cuvier. He died in Paris of cholera. Portrait by François-André Vincent, Whitfield Fine Art Georges CuvierCuvier was born in Montbéliard, France (in department of Doubs), where his Protestant ancestors had lived since the time of the Reformation. His father, Jean George Cuvier, was a lieutenant in the Swiss Guards and a bourgeois of the town of Montbéliard; his mother was Anne Clémence Chatel.

Highly speculative
The title of this book obviously has its origins in "semiotics", a school of philosophy and linguistics of French origin, and the author, being French himself, is clearly influenced by this school (although in this book no admission to this is made). He does however discuss why he chose the name "semiophysics": namely to seek out "significant forms", and to build a "general theory of intelligibility". The author attempts to show in the book that there are only certain elements of reality that really make sense and only these can be used as a basis for a meaningful linguistic description. Thus one must find "stable elements" or "salient forms" which the author contends have the shape of balls, and interact like living beings. Mathematically speaking, the "balls" are bounded closed sets of maximum dimension (three in this case). There are then "pregnances" which propagate from one salient form to another. The form can then change its state, and can re-emit the pregnance, the latter of which may or may not be changed in the process. The author endeavors to combine this approach with what he had discovered in the works of Aristotle.

Those readers who know of the author's work in mathematics, particularly in differential topology, may perhaps be surprised by the content of this book. There are some interesting concepts elucidated in it, but as a whole the wording and argumentation are rather difficult to follow. Catastrophe theory, a theory developed by the author in the 1960s, is used here in an attempted justification of the Aristotelian notion of "continuity". Thus the book could be viewed as an interpretation of Aristotle from the viewpoint of catastrophe theory. The concept of continuity is primordial for the author, for he believes that discontinuity, which is modeled by the formalism of catastrophe theory, requires continuity for its definition. Most interestingly though, the author holds that all epistemology must be "genetic", for it must, in his words, take into account the the effect of evolutionary alterations that humans have been subjected to for many millenia. But he still presupposes, and says so explicitly, the Euclidean nature of space-time, asserting that the discovery of non-Euclidean geometry and general relativity are irrelevant to the problems which he is going to discuss. These discoveries, he says, belong to the "ontological region", and lie outside the cognitive activity of ancient man. The goal of the book is to take concepts from the "exact" sciences, such as the notion of a field in physics, phase transitions (implying discontinuities), and the notion of individuality. These notions are then extended to abstract spaces of a semantic character (this move clearly overlapping what is done in semiotics). Chapter 8 of the book, entitled "Aristotelian Perspectives in Language Theory" is another example of the influence of semiotics on the author's project.

There are some discussions in the book that reflect the time of publication. For instance, the author speaks of the replacing of a point by a small oscillator that duplicates itself, and remarks that this concept may be useful from a quantum mechanical standpoint. But string theories were definitely around at the time of publication, and the replacing of point particles by strings that oscillate, and are created and destroyed, is an example of what the author is asserting (but does not elaborate on in any detail). Also, the catastrophe theory of the author was supposed to model the (discontinuous) processes of cell division, or "morphogenesis". He remarks, interestingly, that "not much is known about the internal structure of the cytoplasm", and so "any attempt at symbolizing cellular dynamics can only be speculation". But since the time of publication of this book, the mathematical modeling of cellular dynamics has really taken off, and there is now a large group of researchers that are attempting to create a comprehensive mathematical model of the cell. Most of these developments do not involve catastrophe theory, no doubt because of its qualitative emphasis.

Thus as a whole the book is highly speculative and pre-scientific. It might be difficult to appreciate by the general scientific crowd, for one must have a background in both catastrophe theory and Aristotelian philosophy in order to follow it. My opinion is that the current emphasis on quantitative mathematical modeling in all of the areas that the author discusses will continue to be the dominant one as we move further into the 21st century. All of this effort requires meticulous validation and experimentation, especially in the medical and biological areas. The truth of these efforts will thus be defined by the success they have on human health, and, with the exception of problems in medical ethics, "philosophical foundations" will take a back seat. Science does not need such a foundation. ... Read more

Excerpt: Thomas Doll (born 9 April 1966 in Malchin, Mecklenburg-Vorpommern) is a former footballer and coach who currently works for Gençlerbirlii S.K. Doll began his career with local side BSG Lokomotiv Malchin, before joining East German first-division DDR-Oberliga side Hansa Rostock. In 1986 he was moved to BFC Dynamo, the country's dominant, Stasi-supported club, where he won two titles, in 1987 in 1988. After reunification Doll was one of the most sought-after players of coming out of the former DDR, and he joined Hamburger SV in 1990. After just one season there he had impressed sufficiently to move to Italian side Lazio for a then record fee of 15 million DM. He played at Lazio for three years, and was part of Germany's squad for Euro 92 where the side finished as runners-up. In 1994 he returned to the Bundesliga, joining Eintracht Frankfurt, but he was hampered by injuries in the two years he spent with the club and made only 28 appearances. After a year in Italy with A.S. Bari, he returned to Hamburger SV i...More: http://booksllc.net/?id=862138 ... Read more
