4.1 Switches

I have just indicated that a processor is made up of millions of electronic components manufactured as one very complex circuit. The majority of these components act as switches that can exist in one of only two states, either on or off. The states of certain switches tell the processor what instructions to carry out.

2.7 Art, life and the interpretation of pictures

David Carrier's book, Principles of Art History Writing (1991) considers the way that Caravaggio has been constructed as an artistic personality (the relevant chapter is below).
