Following a talk by statistician Kajsa Møllersen, Toril Johannessen presents the lecture The Quantifying Spirit which looks at how numbers, spreadsheets, graphs and calculations are employed to describe and map out the natural world. Through a presentation of her recent work Skogsaken, and the series of works Words and Years (included in the LIAF exhibition), the artist will consider how a concept such as the environment has as much to do with technology as with nature.
