Extractions: Karl Heinrich Graeffe (1799-1873) invents a widely used method to determine numerical roots by hand. Similar ideas had already been suggested independently by Edward Waring (1734-1798), Germinal Pierre Dandelin (1794-1847), Moritz Abraham Stern (1807-1894), and Nickolai Lobachevski (1792-1856). Johann Franz Encke (1791-1865) later perfects the method.
Untitled Document The following justification of their equivalence is based on ideas first conceivedby germinal dandelin in 1822 and are of my favourite bits of mathematics. http://www.dpmms.cam.ac.uk/~ims25/conics.html
Extractions: Since their first discovery, credited to a Greek man Menaechmus, some 350 years before the common era, conic sections have been observed in a variety of situations. The Earth travels round the sun in the shape of an ellipse, radio dishes and car headlights are parabola shaped because of the way light is reflected from their surface (radio dishes receiving light and car headlights emitting light) and in my own research I recently came across these curves while investigating convergence criteria of continued fractions. We now have a fair few examples of.... what exactly? The Greeks gave the official definition of conic sections as the curves formed through the intersection ('section') of a cone ('conic') and a plane. The curves are the outlines of the intersecting region. In the example at the beginning, the cone was the beam of the torch, the plane was the floor and the intersection was the image on the floor. It has since proved most consistent to define the conic sections as the curves formed through intersecting a plane and two cones, one above the other. %%%%% ELLIPSE,PAR,HYP %%%%%
Extractions: Conseiller au Cabinet du Ministre des Technologies La recherche fondamentale Les choix furent si contestés que le ministre jugea bon de s'en expliquer : Malgré son agressivité et son persiflage, le texte vaut d'être médité. L'équilibre entre influence française et influence allemande sera maintenu par le gouvernement de la Belgique indépendante, combiné avec le recrutement local, voire dynastique. Il produira les plus heureux effets, en faisant de Liège un microcosme de la science européenne. L'influence allemande, quant à elle, imprègne l'enseignement des lettres, du droit et surtout de la médecine. Fohmann y sera suivi par Joseph Antoine Spring (1814-1872) élève de Von Ringseis à Berlin, par Théodore Schwann, élève de Müller à Bonn et à Berlin, puis par Gussenbauer, Fuchs et von Winiwarter. Or, toute cette génération est profondément influencée par la Naturphilosophie qui l'incite en même temps aux spéculations théologiques les plus élevées et à l'expérimentation la plus rigoureuse. Gaëde et Spring ont été disciples de Schelling.

Ellipsi On Kartioleikkaus (Solmu 1/1998-1999) dandelinin palloja (belgialainen matemaatikko ja insinööri, mm. Napoleonin armeijassataistellut germinal Pierre dandelin, 17941847; ks. lähemmin St. http://solmu.math.helsinki.fi/1998/2/kivela/
Extractions: Ellipsi on tapana määritellä käyräksi - tai oikeastaan pistejoukoksi - jonka jokaisella pisteellä on seuraava ominaisuus: jos lasketaan ellipsin pisteen etäisyydet kahdesta kiinteästä pisteestä ja muodostetaan näiden summa, niin tulos on vakio, so. riippumaton siitä, mikä ellipsin piste on kyseessä. Kiinteitä pisteitä kutsutaan ellipsin polttopisteiksi Jos polttopisteet sijoitetaan xy -tason pisteisiin (c,0) ja (-c,0) ja merkitään etäisyyksien vakiosummaa , saadaan ellipsin yhtälöksi x /a + y /b , missä on merkitty b = a - c . Tämän johtaminen on hyvä analyyttisen geometrian harjoitustehtävä; suosittelen lukijalle. Toisaalta ellipsin sanotaan olevan myös kartioleikkaus . Muita kartioleikkauksia ovat paraabeli ja hyperbeli, joihin en tässä lähemmin puutu, vaikka ne voisikin käsitellä samaan tapaan. Ajateltakoon suoraa ympyräkartiota kuva 1 ). Tämän voi ajatella syntyvän seuraavasti: Olkoon annettuna ympyräviiva ja kiinteä piste - kartion huippu . Tämä sijaitkoon sellaisella ympyrän tason normaalilla, joka kulkee ympyrän keskipisteen kautta. Jos suora liikkuu siten, että se kaiken aikaa kulkee huipun kautta ja tukeutuu ympyräviivaan, syntyy kartiopinta. Itse asiassa kyseessä on kaksihaarainen kartiopinta suoran äärettömästä pituudesta johtuen: symmetriset kartiomaiset osat huipun kummallakin puolella. Liikkuvalla suoralla on tietty kaltevuus ympyrän tasoon nähden. Leikataan kartiota tasolla, jonka kaltevuus on tätä pienempi (

Sin embargo, cierto es que este año-1994-celebramos el bicentenario del nacimiento del Coronel G.P. Dandelin, cuyas aportaciones a la geometría, aún siendo generalmente conocidas, es necesario analizar. ABSTRACT While any scientific article ought to be as up to date as posible, we have preferred to place this one within the framework of the History of Science. However, it is true that this year-1994-we celebrate the two hundredth anniversary of Colonel G.P. Dandelin's birth, whose contributions to geometry, although generally well-know, need to be analyzed.
Dandelin's Spheres (PRIME) This article presents a now classic proof, due to the French/Belgian mathematicianGerminal dandelin (1794 1847), which shows the equivalence of these http://www.mathacademy.com/pr/prime/articles/dandelin/index.asp
Extractions: We take the case of an ellipse; the other cases are quite similar. As a conic section, an ellipse is the intersection of a cone and a plane whose angle to the vertical is larger than that of the generator of the cone. That is, it is the curve that results when a plane slices right through one of the nappes of the cone. The standard proof of this fact is straightforward, but we'll content ourselves with noticing that it follows more or less immediately from the symmetry of the situation. Indeed, if we rotate the above figure about its axis of symmetry, we get an immediate extension to the case of a sphere inscribed in a cone:
