“Eadweard Muybridge understood that a single photograph was of little use when you are trying to understand the movement of an subject. Movement is inherently a function of moving through time and space. Muybridge’s genius was that the even though a single photograph could only reveal a frozen moment in the movement of an object, a series of photographs are able to reveal a much more accurate description of movement…In Picasso and Duchamp’s paintings, it is difficult to tell if it is the subject or the object that is moving.”
