Re: Art work.
Cubism is actually a form of abstract perspective. Basically it broke things down into their most basic forms and would basically show several views of the same object. The perspective is never actually wrong, but imagine seeing a person from the left, front, and right, at the same time. This essentially dissolved time because it is impossible for you to be in 2 places at once, thus to be at another place it must be another time and to be at another time you would be in a different space. Thus these paintings relate to the theory of time=space. Back then art and science were not so different.
Sorry if all of this seem incoherent, I'm very tired.... -.-
