Imaginethe unpredictableand sometimes counterintuitive applicationsofmathematicsinallareasofhumanendeavour. Imaginationandmathematics,imaginationandculture,cultureandmathematics. For some years now the world of mathematics has penetrated deeply into human culture,perhapsmoredeeplythaneverbefore,evenmorethanintheRenaissance. In theatre, stories of mathematicians are staged; in cinema Oscars are won by films about mathematicians; all over the world museums and science centres dedicated to mathematics are multiplying. Journals have been founded to explore the relationships between mathematics and contemporary art and architecture. Exhibitionsare mountedto presentmathematics, artand mathematicsand images relatedtotheworldofmathematics. The volumes in the series Imagine Math are intended to help readers grasp how much that is interesting and new is happening in the relationships between mathematics,imaginationandculture. ThisseventhvolumeisdedicatedtotheItalianpoet,visualartistandwriterNanni BalestriniwhodiedMay2019.Hetookpartinthe2015VeniceConferencewitha presentationandanexhibitiondedicatedtohiscombinatorialbookTristanoandhis combinatorialfilmTristanoil(ImagineMaths5,2016).
