The goal of a world where body weight was not cause for discrimination or denigration is a nobel one, but at what cost?  In the zero sum game point of view some activist have it seems that for people of high BMI to gain, those who are of normal BMI must loose?  

Robert Wald has formulated QFT in curved space time in terms of it's algebra of observables on a manifold.  In doing so he has, perhaps unintentionally, provided framework in which very different theories of quantum gravity look very similar. 

Approximately $1500 worth of fried electronics has taught me a valuable lesson.

I posted a very short rough paper here a while back.  "Dark Matter and Energy as Particles and Fields of Unobserved Scalar and Vector Fields (PDF) (rev2).." Since then certain comments and supposed extremely elementary errors have been pointed out.  The following is a referee report from a well respected journal.  These are (mostly) valid critiques stated in a polite and professional manner.  None of the things which were pointed out by bloggers are here, which were for the most part so elementary that if true there would not even have been a peer review. 

Created in a Bose Einstein Condensate, sound may enter these acoustic black holes but it may not leave.  This creates an system we can experiment with on a table top level and learn about black holes from it.  

The strange and unique features of the Bose condensate never cease to surprise us.  A while back they were used to slow a beam of light almost to a standstill. Now a research team out of the institute of technology in Haifa Israel claims to have created "A sonic black hole in a density-inverted Bose-Einstein condensate." by O. Lahav, A. Itah, A. Blumkin, C. Gordon, and J. Steinhauer (Arxiv link to PDF). 

Harry Benjamin Syndrome, at first a uncontroversial and innocuous idea that transsexual brains are different from other brains, has morphed into a platform for some to denigrate others under a cloak of true pseudoscience proposed by laypeople and supported by not one reputable sexologist, psychologist, or psychiatrist.  What some of them have done is take to attacking anyone who does not fit with their ideal of what a real "woman born transsexual" is (Like a transsexual who does not want sexual reassignment surgery.)  All they while complaining about how oppressed they feel.  This is just a little snapshot of the bigotry, hy
