  • During the past 20 years the notion of set has been introduced into school mathematics courses not only at the secondary but also at the primary level. When one considers that neither Newton nor Gauss made any explicit use of the concept, it is rather remarkable that teachers have thought it desirable to teach the concept so early in their school courses. I should like to consider briefly some of the many possible reasons, historical and pedagogic, why “set” has become a school topic. One reason is, of course, the belief which Russell and Whitehead fostered in their Principia mathematica in the first decade of the century, that all mathematical concepts can be reduced to the concept of set. I don’t intend to discuss here the extent to which they failed to justify that belief, although I shall have occasion to mention some of the difficulties which their programme ran into. A second reason is the important part which sets have played in mathematical research this century.

  • The importance of being 259

  • R. L. Goodstein

  • The number of the Mathematical Association’s new headquarters in London Road, Leicester is 259.

    This number has some quite interesting features. It is for instance the sum of the three squares

    32 + 52 + 32 × 52,

    and the sum of four cubes

    23 + 23 + 33 + 23 × 33 and 13 + 23 + 53 + 53.

  • The Fundamental Formula in the Algebra of Sets

  • The algebra of sets admits a quite elementary presentation in the form of an axiomatic system, which may well be suitable for sixth form school teaching. In this note, however, I am concerned not with axiomatics but with the development of set theory in terms of the membership relation; or to be more precise I am concerned with that part of set theory which deals only with the Boolean operations and the relations of equality and inclusion, but does not seek to generate sets.
