Journal ArticleDOI
TL;DR: The floating-point number system is contrasted with the real numbers as discussed by the authors, and the author then illustrates the variety of computational pitfalls a person can fall into who merely translates information gained from pure mathematics courses into computer programs, including summing a Taylor series, solving a quadratic equation, solving linear algebraic systems, solving ordinary and partial differential equations, and finding polynomial zeros.
Abstract: The floating-point number system is contrasted with the real numbers. The author then illustrates the variety of computational pitfalls a person can fall into who merely translates information gained from pure mathematics courses into computer programs. Examples include summing a Taylor series, solving a quadratic equation, solving linear algebraic systems, solving ordinary and partial differential equations, and finding polynomial zeros. It is concluded that mathematics courses should be taught with a greater awareness of automatic computation.

Journal ArticleDOI
TL;DR: The tradition of friendship between French and Roumanian scientists, particularly between our mathematicians, is old as discussed by the authors and I am very happy to be a link in this chain, which I hope will continue, stronger and more cordial, in the years to come.
Abstract: Thank you for your kind words on my behalf. I must admit that it is a great pleasure for me to escape from my duties as dean and spend a week in such a warm and friendly atmosphere. The tradition of friendship between French and Roumanian scientists, particularly between our mathematicians, is old. I am very happy to be a link in this chain, which I hope will continue, stronger and more cordial, in the years to come. Well, if you don't mind, I shall not make a very long speech, and I should be happy to answer at the end of it the questions which, no doubt, will be put to me. I don't pretend to deal with all the history of the works of Bourbaki, and I shall give you all a chance to ask questions on the points I merely touch upon.

Journal ArticleDOI
Paul Monsky1
TL;DR: In this article, the authors proposed dividing a square into triangles and then dividing the triangles into squares, based on the idea of dividing a triangle into triangles, and the American Mathematical Monthly: Vol 77, No. 2, pp. 161-164.

Journal ArticleDOI
TL;DR: A note on Commuting automorphisms of rings is given in this paper, where it is shown that the automorphism of rings can be expressed as a function of the number of rings.

Journal ArticleDOI
TL;DR: In this article, the groups which are the Union of Three Subgroups (U3S) are described. But they do not specify the three subgroups as a union of groups.
Abstract: (1970). Groups Which are the Union of Three Subgroups. The American Mathematical Monthly: Vol. 77, No. 1, pp. 52-57.

Journal ArticleDOI
TL;DR: The Helly Type Theorems Derived from Basic Singular Homology (HTH) as discussed by the authors are derived from the basic singular homology (BSH) of the lambda calculus.

Journal ArticleDOI
Morris Kline1
TL;DR: The American Mathematical Monthly: Vol. 77, No. 3, No 3, pp. 264-282 as discussed by the authors, is a seminal work in logic versus pedagogy.
