Extractions: Villanova University, February 19, 2004. The United States Military Academy celebrated its centennial in 1902 but was it a vibrant intellectual center or a school with a hundred years of tradition unimpeded by progress? Since the study of mathematics occupied a substantial portion of the education of every graduate, this motivates us to look at all aspects of the department of mathematics: Who were the faculty? What was their education and experience? What was the curriculum? Which textbooks were used? How were the classes conducted? How did the department interact with the national mathematical community? How did world events impact the department? In terms of leadership, during the first half of the twentieth-century the history of the Department of Mathematics is rather simple because the department had only four Department Heads. Wright P. Edgerton served from 1898 to his death in 1904 and was succeeded by Charles P. Echols who served from 1904 until 1931 when he retired at the mandatory retirement age of 64. Because of that long term, he will be the major player in our story. Harris Jones took up the post in 1931 and served until 1947 when he became Dean of the Academic Board. Finally William W. Bessell, Jr., was Head from 1947 until 1959 when he became Dean.
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 (

The sex of hatchling crocodilians is determined by the incubation temperature of eggs in the laboratory as well as in nature. The talk consists of two parts. The first part gives a review of the biological problem. Two experimental observations are used: that male fitness depends more strongly on the quality of the incubation environment than female fitness, and that females lay eggs at a temperature close to the temperature at which they themselves were incubated. In the second part, we derive a population genetics model based on the above mentioned biological concepts. A method for finding the optimal sex ratio as a function of temperature is developed and applied under different assumptions. Numerical solutions are given and compared with available experimental data. Integrating Factors of ODEs and Systems of Linear PDEs
