http://www.gemarsh.com Sun, 26 Oct 2008 18:17:34 +0000 http://backend.userland.com/rss092 en In 2005, the Royal Society published a report titled Ocean acidification due to increasing atmospheric carbon dioxide.  The report’s principal conclusion—that average ocean pH could decrease by 0.5 units by 2100—is demonstrated here to be consistent with a linear extrapolation of very limited data.  It is also shown that current ... http://www.gemarsh.com/archives/105 Foundations of Physics Vol. 38, pp. 959-968 (2008) The original publication is available at www.springerlink.com http://dx.doi.org/10.1007/s10701-008-9245-x It has been shown that for the Reissner-Nordström solution to the vacuum Einstein field equations charge, like mass, has a unique space-time signature [Found. Phys. 38, 293-300 (2008)]. The presence of charge results in a negative ... http://www.gemarsh.com/archives/97 The assumption that the vacuum is the minimum energy state, invariant under unitary transformations, is fundamental to quantum field theory. However, the assertion that the conservation of charge implies that the equal time commutator of the charge density and its time derivative vanish for two spatially separated points is ... http://www.gemarsh.com/archives/101 Essays in the Philosophy of Humanism Volume 16(1) Spring-Summer 2008. Pope Benedict XVI interleaved two themes in his talk at the University of Regensburg on September 12, 2006. These are discussed here in two separate parts: Truth, Faith, and Reason and The Dialogue of Cultures. The first addresses the ... http://www.gemarsh.com/archives/54 It will be argued here that the cosmological constant problem exists because of the way the vacuum is defined in quantum field theory. It has been known for some time that for QFT to be gauge invariant certain terms—such as part of the vacuum polarization tensor—must be eliminated either ... http://www.gemarsh.com/archives/87 During most of the Phanerozoic eon, which began about a half-billion years ago, there were few glacial intervals until the late Pliocene 2.75 million years ago. Beginning at that time, the Earth’s climate entered a period of instability with the onset of cyclical ice ages. At first these ... http://www.gemarsh.com/archives/92 USA Today Magazine (January 2008) Goracle PDF "We are about to waste an enormous amount of money and effort on carbon mitigation without lowering CO2 emissions one whit.

The original publication is available at www.springerlink.com http://dx.doi.org/10.1007/s10701-008-9209-1 Charge, like mass in Newtonian mechanics, is an irreducible element of electromagnetic theory that must be introduced ab initio. Its origin is not properly a part of the theory. Fields are then defined in terms ... http://www.gemarsh.com/archives/84 The sun’s role in the earth’s recent warming remains controversial even though there is a good deal of evidence to support the thesis that solar variations are a very significant factor in driving climate change both currently and in the past.

The Left in the US is in crisis. It has lost the broad support it once enjoyed in the working class and finds itself captive to the past—or, worse yet, to an ... http://www.gemarsh.com/archives/30
