The key to understanding the current chaos in the Middle East is to recognize that the primary identity of its people is with their religion, sect, tribe, family — not the states formed following the breakup of the Ottoman Empire.

Defeat of the Islamic State cannot be achieved by solely military means and, most especially, not by Western military actions such as the air strikes—even if given the cover of a coalition containing Arab nations; nor can military operations decrease the spread of beliefs upon which radical Islam is based.
This essay examines our fundamental conceptions of time, spacetime, the asymmetry of time, and the motion of a quantum mechanical particle. The concept of time has multiple meanings and these are often confused in the literature and must be distinguished if any light is to be thrown on this age-old issue. The asymmetry of time also has different meanings that depend on context—although the fundamental time asymmetry is associated with the expansion of the universe. These and related issues are discussed in both classical and quantum mechanical contexts.

The phrase “the human condition” has come to mean many things to different people, but here it simply refers to what history has shown to be the inescapable features of being human. In this essay we take a look at current trends, what they foretell for the remainder of this century, and how the characteristics that make us human might affect the evolution of those trends.

The Einstein field equations have no known and acceptable interior solution that can be matched to an exterior Kerr field. In particular, there are no interior solutions that could represent objects like the Earth or other rigidly rotating astronomical bodies. It is shown here that there exist closed surfaces upon which the frame-dragging angular velocity and the red-shift factor for the Kerr metric are constant. These surfaces could serve as a boundary between rigidly rotating sources for the Kerr metric and the Kerr external field.

In the December 2013 issue of Physics Today David Kramer tells us—in an article titled A nuclear bomb worth more than its weight in gold?—that “some critics of the B-61 life extension program question whether the program is necessary.” And, “Representative John Garamendi (D-CA) questioned why the B-83, a newer bomb that officials acknowledge won’t need a life extension for at least 10 years, shouldn’t replace the B-61”. Strangely enough the article omits the principal reason why the administration may think the B-61 is worth more than its weight in gold.

We surely have the means to deal with the locally rational but globally nuts dilemma, the question is whether we collectively have the will to do so. This perhaps is the most important problem we face in the 21st century.

The late 19th century and the beginning of the 20th brought with it a revolution in the scientific understanding of the universe around us, one whose effects are still being felt around the world as it forces people to change their ideas about the universe and the place of human beings within it. Even a conceptual understanding of the early origin of the universe requires an introductory knowledge of quantum mechanics. Unfortunately, the attempt to reconcile quantum mechanics with concepts brought over from classical mechanics has led to much confusion especially among non-physicists and students of physics. This essay is an attempt to address some of this wide spread confusion.
