In 1931 Kurt Godel published his fundamental paper, "On Formally Undecidable Propositions of Principia Mathematica and Related Systems." This revolutionary paper challenged certain basic assumptions underlying much research in mathematics and logic. Godel received public recognition of his work in 1951 when he was awarded the first Albert Einstein Award for achievement in the natural sciences--perhaps the highest award of its kind in the United States. The award committee described his work in mathematical logic as "one of the greatest contributions to the sciences in recent...

Griddlers logic puzzles, also known as Picross or Nonograms, are picture logic puzzles in which cells in a grid have to be colored or left blank according to numbers given at the side of the grid to reveal a hidden picture. Some people compare Griddlers to Sudoku. However, the Griddlers puzzles always reveal a nice image as a result.

This book consists of 196 Triddlers puzzles, from small and easy up to big and complicated ones that may take several hours to solve. The solutions of the puzzles appear at the end of the book.

Dans ce long article, paru en allemand en 1964, Kurt Ebbinghaus propose, dans la lignEe des travaux de Paul Lorenzen, une reconstruction de la thEorie du syllogisme A partir d'un modEle calculatoire. Dans ce modEle, les syllogismes sont pensEs comme des rEgles et la question de la validitE logique est formulEe en termes de « procEdure et non en termes de « vEritE . L'intErEt de le traduire aujourd'hui pour la premiEre fois n'est pas seulement qu'il offre de quoi mesurer combien Aristote est un grand logicien, parfaitement maItre des outils formels qu'il Elabore dans les...
