Il n&rsquo;existe qu&rsquo;un nombre fini de sym\u00e9tries possibles lorsque l&rsquo;on agence des \u00ab\u00a0tuiles\u00a0\u00bb de mani\u00e8re r\u00e9guli\u00e8re. Les fresques du palais de l&rsquo;Alhambra en Espagne en sont un bon exemple, puisqu&rsquo;elles contiennent tous les types de motifs r\u00e9guliers possibles. Motiv\u00e9s en partie par l\u2019aspect esth\u00e9tique du probl\u00e8me, les math\u00e9maticiens ont longtemps cherch\u00e9 des formes de tuiles qui soient irr\u00e9guli\u00e8res par nature. Ces formes, dites \u00ab\u00a0ap\u00e9riodiques\u00a0\u00bb, peuvent ainsi s&rsquo;agencer en motifs immenses, mais jamais de mani\u00e8re r\u00e9guli\u00e8re. Depuis la d\u00e9couverte des tuiles de Penrose en 1972, il est devenu possible de cr\u00e9er des fresques \u00e0 la limite entre le r\u00e9gulier et l&rsquo;irr\u00e9gulier. Il faudra attendre 2023 pour que l&rsquo;on d\u00e9couvre une unique tuile avec cette propri\u00e9t\u00e9.<\/p>\n<p>Cette conf\u00e9rence se tiendra \u00e9galement :<\/p>\n<ul>\n<li>Mardi 19 janvier
