The series Probable Drawings, by the British duo Semiconductor, invites us to explore quantum physics through line and uncertainty. Each drawing is created using a single continuous line that represents electronic orbitals—regions where electrons might be found, though never with complete certainty. Rather than depicting exact locations, the works reveal a map of probabilities that reflects the unpredictable nature of the quantum world. The process combines traditional techniques —such as carbon paper— with digital tools like a plotter, leaving visible the imperfections of the line as a metaphor for chance and the beauty of uncertainty.
