For more information on this see C.P. Snow's over half-century-old lecture, "The Two Cultures." Within it he posits a great rift between the humanities and the sciences. The lecture is very much relevant to this discussion. As a side note, Edge.org posits itself as an abridging third culture in direct relation to antagonisms between the humanities and sciences. Also on this front is 3 Quarks Daily, which is a more or less excellent feed of multi-discplinary geekdom.
