Developments in science and technology have always influenced art. From mathematics, artists learnt about perspective; chemical processing gave affordable colours, and colours previously not seen. Newton and Goethe’s work on colour vision helped artists to understand colour. For example, Turner and Mondrian applied Goethe’s theories. Psychologists raised awareness of colour constancy and adaptation, while photography showed stages of movements not perceived by the eye, as seen in works by Duchamp and Picasso. Science and technology itself can be subjects of art, be it in the laboratory or workshop. Mohamed Sobhy will explain these ideas through examples of artwork from medieval times to thepresent day.
