The Grand Design (book) The Grand Design is a popular-science book written by physicists Stephen Hawking and Leonard Mlodinow and published by Bantam Books in 2010. The book examines the history of scientific knowledge about the universe and explains 11 dimension M-theory. The authors of the book point out that a Unified Field Theory (a theory, based on an early model of the universe, proposed by Albert Einstein and other physicists) may not exist.
Postinternationalism Postinternationalism is a term coined by academic James N. Rosenau to describe "an apparent trend in which more of the interactions that sustain world politics unfold without the direct involvement of states". Postinterational approaches to international relations theory emphasis the role of non-state actors, the existence of international norms as well as the process of globalisation and the existence of intra-state (rather than interstate) violence. As such postinternational approaches rejects many the tenets of realist approaches to international relations theory though it accepts that international politics is anarchic. Rosneau's paradigm of postinternationalism is sometimes referred to in academic literature as "turbulence theory".
