History of mathematicians In this document we give some information of mathematicians which work or names are used in the course wi3097 "Numerieke methoden voor differentiaalvergelijkingen". 1. Mathematical preliminaries Modern applied mathematics started in the 17 and 18 century with people like Simon Stevin (1548-1620) René Descartes (1596-1650) Isaac Newton (1642-1727) and Leonhard Euler (1707-1783) . Numerical aspects were used in analysis in a natural way; the name numerical mathematics was unknown. Numerical methods developed by Newton, Euler and later Carl Friedrich Gauss (1777-1855) play an important role in present day numerical mathematics. Additional information about Simon Stevin (in Dutch). November 1947 can be seen as the birthday of modern numerical analysis. The Taylor polynomial ( Brook Taylor (1685-1731) ) is used to analyse the error in various numerical approximations. The order symbol of Landau ( Edmund Georg Hermann Landau (1877-1938) ) is used to give a short notation of the approximation errors. 2. Interpolation

History of mathematicians In this document we give some information of mathematicians which work or names are used in the Finite Element part of the course Computational Fluid Dynamics II (a PhD course from the JM Burgerscentrum ). The course is based on the following book: Finite element methods and Navier-Stokes equations, C. Cuvelier and A. Segal and A.A. van Steenhoven, Reidel Publishing Company, Dordrecht, 1986. 1. Introduction Many flow problems are described by the Navier-Stokes equations Claude Louis Marie Henri Navier (1785-1836) and George Gabriel Stokes (1819-1903) 2. Introduction to the Finite Element method In boundary value problems a differential equation is given together with appropriate boundary conditions, in order to make the solution unique. There are various boundary conditions possible. We consider a heat equation, where the required solution describes the temperature (T). To derive the differential equation equation the law of Jean Baptiste Joseph Fourier (1768-1830) is used, which the heat flux with the first derivative of the temperature. As boundary conditions one can prescribe the temperature (called a Dirichlet condition Johann Peter Gustav Lejeune Dirichlet (1805-1859) ) or one can prescribe the flux, the first derivative of the temperature (called a Neumann condition

Raphson Joseph Raphson was born in 1648 and died in 1715. He attended Jesus College Cambridge and graduated in 1692. However even before he graduated, his book Analysis aequationum universalis was published (1690). This book contained The Newton Raphson Process. In 1691, as a result of this book, Raphson became a member of the Royal Society. In 1702, Raphson produced A Mathematical Dictionary and a second edition of his analysis book. Raphson also wrote about how mathematical theories can be applied to theological issues such as inifinite space. His theology was based on Cabalist ideas. Cabal is a form of Judaism. The result of these studies was two books: De Spatio reali (1702) and Demonstratio de deo Raphson also wrote History of Fluxions which wasnt published until after his death in 1715. In this book Raphson showed support for Newton's work rather than Leibniz's. Newton didn't show his mathematical work to many people, yet Raphson had the privilege of seeing his papers. In 1720, Universal Arithmetic was published. This was Raphson's English translation of Newton's

Historische Noot bij de Wetenschappers geciteerd in hoofdstuk III Methoden om veeltermvergelijkingen op te lossen behoren tot een zeer oud onderzoeksgebied, dat teruggaat op zijn minst tot in de Babylonische periode. Er zijn veel methoden hiervoor beschreven in de literatuur en veel nieuwe methoden zijn in de laatste decaden ontwikkeld. De eerste publicatie, die de oplossing van de vergelijkingen van de derde graad bevat, vond plaats in het werk van Hieronimo Cardano Ars magna de Regulis Algebraicis uitgegeven in Leiden in 1637. Sir Isaac Newton Later publiceerde hij de methode die nu toegeschreven wordt aan Newton en Raphson, als een middel om de Kepler vergelijking voor de bepaling van de baan van een planeet op te lossen. In 1687 verscheen zijn Philosophiae Naturalis Principia Mathematica , het fundament van de mechanica en de gehele klassieke natuurkunde. In 1701 trad hij af als hoogleraar te Cambridge; zijn ex-collega's kozen hem om hen in het parlement te vertegenwoordigen; in 1705 verhief koningin Anna hem in de adelstand. In de laatste decennia van zijn leven was de wetenschappelijke activiteit van Newton zeer beperkt. Hij verrichtte veel werk voor de voorbereiding van de tweede uitgave van de Principia, in samenwerking met de jonge wiskundige Cotes (zie ook cursus Numerieke Analyse en numerieke methoden ter benadering van bepaalde integralen).

A tutorial in the optimization of computed molecular structures Michael P. Hamelin and Joseph T. Rizzolo Chemistry Department Norwich University, Northfield VT 05663 Introduction Computational chemistry has found a place in the undergraduate curriculum as an aid in the rationalization of trends in experimental data [ ] . Most investigations involving these computational models begin with the prediction of a molecular structure which is a result of a model theory (molecular mechanics, empirical molecular orbital theory, etc.) and an optimizing algorithm. We have developed practical exercises, suitable for self-study, that can give insight to students on how these models obtain the resultant structures. We hope that these exercises result in more informed and responsible users of computational models in the prediction of molecular geometries [ These exercises use MMX [ ] empirical force field parameters that determine the gross geometry of the molecule (stretching, bending and torsional twisting contributions to the energy) to define the energy surface of the molecule. For purposes of optimization, we use the Newton - Raphson method [ ], since our students are are already familiar with it. Emphasis is placed on the role of energy derivatives in the optimization, and, more importantly, in characterizing the resulting structure. We also make the link between the second derivatives of the energy to vibrational spectroscopy. In this context, then, the prediction of the vibrational spectrum is an important diagnostic tool incorporated in virtually all commercial modeling packages.

As such, it is an example of a root-finding algorithm The idea of the method is as follows: one starts with a value which is reasonably close to the true zero, then replaces the function by its tangent (which can be computed using the tools of calculus ) and computes the zero of this tangent (which is easily done with elementary algebra). This zero of the tangent will typically be a better approximation to the function's zero, and the method can be iterated. Suppose f a b R is a differentiable function defined on the interval a b ] with values in the real numbers R . We start with an arbitrary value x (the closer to the zero the better) and then define for each natural number n Here
