Zermelo, Ernst Friedrich Ferdinand German mathematician who made important contributions to the development of set theory, particularly in developing the axiomatic set theory that now bears his name. In 1904 Zermelo defined the axiom of choice, the use of which had previously been unrecognized in mathematical reasoning. The first formulations of axioms for set theory - an axiom system for German mathematician Georg Cantor' s theory of sets - were made by Zermelo in 1908.

Back to Laurence Kirby's home page Steps towards a logic of natural objects Laurence Kirby Baruch College, City University of New York This article appeared in Epistemologia vol XXV (2002), pp.225-244. 1. Introduction The natural objects that I propose to consider are broadly those physical objects which are studied and referred to by science and by a common sense view, informed by science, of the world. Natural objects are, philosophically speaking, individuals ; they are involved as units in dynamic, causal processes. I shall draw a distinction between natural objects and the abstract objects of mathematics, in particular set theory. Natural objects encompass atoms and molecules; cells and organisms, including you and me; the objects of everyday life such as chairs and automobiles; nations, continents, ecosystems, mountain ranges, geological faults; planets, stars and galaxies. Each natural object, when regarded internally, is a dynamic system with various interacting parts and components (some of which may be natural objects in their own right); when regarded externally, a natural object acts as a unit with respect to a larger system or systems (which may again be natural objects) of which the given object forms a part or component. It is sometimes argued that objects such as atoms or galaxies are theoretical constructs, as much so as mathematical objects (or even, according to some, more so). It is true that any reference to an object rests on epistemological assumptions. The approach here will be not to belittle these important epistemological questions but to leave them aside, and accept as a working assumption the practical viewpoint of people who are dealing with the world: that natural objects exist, act, and are acted upon, independently of the observer although any description of them or of their actions is dependent on the describer.

Ernst Friedrich Ferdinand Zermelo Ernst Zermelo's father was a college professor, so Zermelo was brought up in a family where academic pursuits were encouraged. He graduated from gymnasium in 1889. At this time it was the custom for students in Germany to study at a number of different universities, and that is what Zermelo did. He studied at Berlin, Halle and Freiburg, and the subjects he studied were quite wide ranging and included mathematics, physics and philosophy. At these universities he attended courses by Frobenius, Lazarus, Fuchs, Planck, Schmidt, and Schwarz. Zermelo began to undertake research in mathematics after completing his first degree. His doctorate was completed in 1894 when the University of Berlin awarded him the degree for a dissertation on the calculus of variations. In this thesis he extended Weierstrass's method for the extrema of integrals over a class of curves to the case of integrands depending on derivatives of arbitrarily high order, at the same time giving a careful definition of the notion of neighbourhood in the space of curves. After the award of his doctorate, Zermelo remained at the University of Berlin where he was appointed assistant to Planck who held the chair of theoretical physics there. At this stage Zermelo's work was turning more towards areas of applied mathematics and, under Planck's guidance, he began to work for his habilitation thesis studying hydrodynamics.

Si interessò al calcolo delle variazioni e soprattutto alla teoria degli insiemi, di cui diede la prima formulazione assiomatica in sette postulati, il sesto dei quali, noto anche come assioma della scelta, ha profonde implicazioni concettuali e diede origine a vivaci discussioni circa la sua legittimità. Nel 1908, infatti egli mise in evidenza il fatto che Cantor assioma di Zermelo , o delle infinite scelte arbitrarie.
