Today’s edition of CNN.com includes a story on the job cuts in the D.C. public schools. The story leads with the fact that 545 teachers and 226 others will be losing their jobs, but the really interesting details are in the last several paragraphs.
According to the article, the school has 65,099 students, 14,058 total employees (1 non-teaching employee for every 7.52 students), and 5,400 teachers (1 teacher for every 12.06 students). Teachers make up barely a third of the school system’s employees, and the student to teacher ratio is worse than the non-teaching employee ratio to students!
Looking through my newspaper clippings, I came across an LA Times article from 2002 citing a University of Idaho fire ecologist, claiming a link between heavy logging and an increase of big-burn forest fires. I ’m not sure of the validity of the claims in the article, but the accompanying charts of logging and fires from 1945 to 1995 are interesting in and of themselves.
In the RANT, physics teacher Dom Crea gives his perspective on the energy efficiency in a hydrogen economy.
Recently, a listener to Dr. Bill’s show came up with some clever definitions for stupid liberals and conservatives. Libiot is a contraction of liberal and idiot, while conservadum is a contraction of conservative and dummy. The full definitions of Libiot and Conservadum have been added to the Pushback Glossary.

because they have not taken all the math classes they need in order to pass the mandated tests.
So why are the politicians and administrators and school boards responsible for this mess allowed to remain in power, and cover their asses by delaying the requirement for another three years?
Page 17 of the July 2001 issue of Popular Science shows a metal can with a honeycomb pattern of indentations on it, formed by water pressure. Invented by Frank Mirtsch, this technique is claimed to provide enough strength to allow 20–40% less material to be used. So why hasn’t some smart government bought the patent, and then given the technology away to anyone that wants to use it? It seems to me that doing so could greatly aid the environment.
I’m not convinced that our government is doing the right things to make sure our public agencies have reliable communications that will work in a disaster. The trend towards fancy trunked radio systems in the 800MHz band may simply be making already incompatible systems even more incompatible and far more unlikely to work during a major disaster.

Paul Georgia writes in the National Review about the facts of hydrogen production and use—that it is very inefficient and creates more pollution than burning gasoline (at least when created using electricity generated by fossil fuel). It could make sense if we could produce it using nuclear power, but not by any other means.
