ABSTRACT
Jean-Baptiste le Rond d’Alembert, French mathematician and scientist, one of the editors of Encyclopedie, died on 29thOctober 1783. Apart from writing thousands of mathematical articles and pages for Encyclopedie, d’Alembert was interested in space and time. Some very serious mathematics came out of it, for example, one of the most influential mathematicians of the nineteenth century Bernhard Riemann introduced the n-dimensional mathematics into mainstream mathematics. An interesting thing about that in particular was that this fourth dimension shook up the foundations of the three-dimensional Victorian society, and included some people who would not otherwise have been given an opportunity to contribute to the development of mathematics due to the social hierarchy of their time. This was in a very subtle and fine way illustrated by Flatland, which aimed at lifting people from the flat world in which men and women have different standing even in their own homes.
