This open access book takes a queer, feminist, and decolonial technoscience approach to the ecologies that emerge from our entanglements with nonhumans (air, rocks, algae, trees, soil and plants) and computational hard/software. In Plants by Numbers , artists and theorists working with computation address the urgent need to think beyond the human paradigm, opening up new fields of debate that question the troubled relationship between ecosystems and human technology. Organised around three key themes--techno-nature entanglements, plants as resistant agents, and becoming-with-plants--the volume provides a vital pathway through complex theoretical ideas that inform the practices of artists working in the fields of computation and ecology. Fusing art theoretical and art practice approaches, the contributors describe how we might design, make and imagine computational processes differently, or otherwise, through the co-production of artworks with plants. Showing how these artworks might act as communicative media between the biological and technological, Plants by Numbers opens up new potential areas of research whilst producing new ethical-political engagements.
