Boris Vian e a matemática

Na fotografia: Sartre e Boris Vian

***

"É muito bonito, é extremamente conhecido e extremamente comum dizer em francês, dizer com orgulho: 'Eu não percebo nada de matemática.' Pessoalmente, faço a seguinte reflexão: 'Se não percebesse nada de matemática teria vergonha de dizê-lo.' Apresentar-se assim de repente como um imbecil não é a melhor maneira de se apresentar."

«As means of introducing the key aspects covered by this invention consider Microsoft Corporation’s computer-based puzzle game Tetravex and the mathematical work of Jorge Rezende, University of Lisbon.
(...)
The mathematical work of Jorge Rezende has been published in the papers entitled “On the Puzzles with Polyhedra and Numbers” and “Puzzles with Polyhedra and Permutation Groups”, available via the web site of the Mathematical Group of the University of Lisbon (http://gfm.cii.fc.ul.pt/people/jrezende/pt/?set_language=pt). The publications cover the mathematical methods behind using polygonal plates (tiles), with numerical indicia ascríbed to each edge, to form the surface of regular polyhedron. Although the analysis is very detailed and covers a method (effectively a search based routine) that determines how many solutions a particular indicia set can produce, i.e. how many different ways the tiles can be arranged to form the surface of the polyhedron by matching adjacent indicia of different tiles, there is no discussion on limiting the allocation of the indicia to ensure an unique solution.»
