Le Livre de l’incomplétude (The Book of Incompleteness) is pluridisciplinary, collaborative and ongoing project, consisting of a website and a free downloadable ebook. This is an artistic appropriation of Kurt Gödel’s incompleteness theorem, resulting in a collective mathematical creation.

Internet users are invited to participate by sending an arithmetic formula whose result must be equal to 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9, using only numbers and the symbols + – x /.
For example:
0 = 1-1
1 = 1×1
2 = 1+1
3 = 3/1

The site has 10 forms, where you must enter your response. An automatic system verifies the accuracy of the proposed solution and a database records the formula, preventing it to be sent again.

Each response is unique. Participations are anonymous and unlimited.
All valid answers are automatically sent to our Twitter feed (@l_incompletude).
