History of Maya calendars, including the modified base 20 number system used in them
A collection of articles about historical and contemporary women in mathematics.
This is page 167 from the Exercitationes mathematicae (1657) of Frans van Schooten (1615-1660). This book contained a collection of mathematical construction problems, among much else. It was one of the books read by Isaac Newton while he was a student at Cambridge University and helped to introduce him to modern mathematics. On this page we see a construction enabling one to find the distance across a river.
The quadrennial meeting of the International Study Group on the Relations between History and Pedagogy of Mathematics will be in Mexico City, July 14-18, 2008.
A discussion of the meaning of mathematical unsolvability in the context of the history of Abel's proof of the unsolvability of the quintic equation in terms of radicals.
A translation of one of the seminal papers in the field of elliptic integrals, but one that can be read by an undergraduate.
Find the area of the elliptical segment cut off parallel to the shorter axis;
A translation of and commentary on Frans van Schooten's work on constructions using only a straightedge. Van Schooten's postulates for use of the straightedge, however, allow the copying of one line segment onto another.
A cylindrical tin tomato can is to be made which shall have a given capacity. Find what should be the ratio of the height to the radius of the base that the smallest possible amount of tin shall be required.
The cost per hour of running a certain steamboat is proportional to the cube of its velocity in still water. At what speed should it be run to make a trip up stream against a four-mile current most economically?
