WHAT'S NEW Robert L. Park Friday, 2 July 2010 Washington, DC 1. CELL PHONES: INTENSITY OF RADIATION SHOULDN'T BE CONFUSED WITH ENERGY. Public understanding of electromagnetic radiation seems to be about 700=20 years behind the times. So I have taken ample literary license in tellin= g=20 the story of the Siege of Calais in 1346. It illustrates the distinction=20 between the intensity of electromagnetic radiation and the energy of=20 photons. The English King, Edward III, alluded to earlier royal-bedroom=20 diplomacy in claiming to be King of France as well as England. Under=20 French rules, however, sleeping around was no big deal and the French Kin= g,=20 Philip, refused to give his crown to Edward. However, Edward had five=20 times as many men as Philip; so he ordered the entire army to assemble on= =20 the Dover cliffs and throw stones at France. That is, the "intensity" of= =20 the bombardment was very high. The closest point was Calais. The shore = in=20 Calais is indeed littered with rocks even today. But are these English=20 rocks thrown by Edward=92s men, or indigenous French rocks? English=20 geologists have launched a ten year study of the rocks to find out. =20 Kinesiologists say it's impossible to throw a rock 34 kilometers. That is= ,=20 the "energy" was much too low to reach Calais. 2. MAUREEN DOWD: "ARE CELLS THE NEW CIGARETTES?," SHE ASKS. In her New York Times column last Friday, Dowd took the cell phone/cancer= =20 issue to a whole new level of ignorance. She askes if technological=20 advances "are really time bombs?" Provocative question, but why would sh= e=20 include cigarettes? Tobacco wasn=92t developed, it was "borrowed" from=20 primitive tribes about 400 years ago. The only "advance" has been to prov= e=20 scientifically that tobacco is harmful, leading to widespread bans and=20 warnings. With the decline in smoking, life expectancy in the most advanc= ed=20 nations has risen to above 80, twice what it is in less developed=20 countries. So what is the time bomb she talks about? Like rocks thrown a= t=20 Calais from Dover, microwaves are far below the cancer energy threshold. = =20 That threshold lies at the extreme blue/ultraviolet end of the visible=20 spectrum. That's why you don't want to spend as much time in the sun as = I=20 did, and certainly don't want to use a tanning salon. Your cell phone is=20 rude and intrusive and a hazard if used on the road, but it won't cause=20 cancer. Why has the media consistently failed to explain this simple fac= t=20 is a mystery.=20 3. CLIMATE GATE: PENN STATE CLEARS MICHAEL MANN OF SOMETHING. The allegations arose following the hacking of private e-mails at the=20 University of East Anglia in the UK. It seemed to be a case of arresting= =20 the victim. A single line, stated out of context, sounded like something= =20 it wasn't.=20 THE UNIVERSITY OF MARYLAND. Opinions are the author's and not necessarily shared by the University of Maryland, but they should be. --- Archives of What's New can be found at http://www.bobpark.org What's New is moving to a different listserver and our subscription process has changed.
