«Deux et deux font-ils quatre ?» is a popular mathematics essay by Didier Nordon, published by Pour la Science in paperback (111 pages, in French).
Didier Nordon reflects on the apparent solidity of mathematics and shows how the most elementary certainties, such as 2+2=4, can become problematic when examined closely. Through examples and paradoxes, he invites the reader to question the foundations of this science and to discover its more fragile and human side.
Published in Paris in 1999, it includes bibliographic references and is classified under number 510 of the Dewey Decimal Classification.
A popular science work for curious readers who want to approach mathematics without prior technical training.
