WHAT=92S NEW Robert L Park Wednesday, 13 March 2012 Washington, DC 1. SMART METERS: AND IGNORANT JOURNALISTS. Several years ago, I signed up for "Google Alerts" about the purported li= nk=20 between "cell-phone radiation and cancer." It's a great service. I get=20 hundreds of Alerts about cell phones, almost all of which are dead wrong.= =20 That's fine; what I'm trying to figure out is why reporters so consistent= ly=20 get it wrong. I tried doing an additional search for "Einstein." It was= ,=20 after all, Einstein's Nobel Prize winning 1905 paper on the Photoelectric= =20 Effect that introduced the concept of wave/particle duality. Einstein=20 described electromagnetic radiation as discrete packets of energy (now=20 called "photons") equal to the wave frequency times Planck's constant. =20 Photoemission is thus possible only for photons of energy greater than th= e=20 ionization threshold (about 5 eV for metals). That's in the ultraviolet=20 region of the radiation spectrum, starting at the blue limit of the visib= le=20 spectrum. Ultraviolet radiation can create mutant strands of DNA that are= =20 the seeds of skin cancer. That's why you should avoid tanning salons. You= =20 should also avoid sticking your head in microwave ovens with the interloc= k=20 disabled. Microwave photons from cell phones, microwave ovens, smart=20 meters, and Wi-Fi all have energies about a million times too low to crea= te=20 mutant strands of DNA. Better you should worry about the impending solar= =20 maximum. Microwaves can cook your goose, but you will die cancer free. 2. BAD CONNECTION: THE ENVIRONMENTAL HEALTH TRUST.=20 The most recent book warning about cell-phone hazards is "Disconnect," =20 Devra Davis(2010, Dutton). Does Disconnect mention Einstein? Well," it=20 quotes him at the start of chapter 11, "The right to search for truth=20 implies also a duty." That's it. It makes no mention of his work, but las= t=20 week something called "The Environmental Health Trust" issued a press=20 release urging the United States to require health warning labels on cell= =20 phones. The President of the Environmental Health Trust is Devra Davis. T= he=20 press release called for donations to support its work 3. FERTILITY: GOOD NEWS WHERE YOU LEAST EXPECT IT. David Brooks, a sort-of conservative New York Times columnist, commented=20 this morning that fertility rates in the Arab world have been declining f= or=20 three decades. Well, not in Afghanistan, which tops the 133 sovereign=20 states of the world with a fertility rate of about seven. But war and=20 poverty always make the fertility rate go up. Afghanistan is at the top =20 with a rate of around seven. 4. IMPORTANT MATTER: IS THE LHC ON THE VERGE OF FINDING THE HIGGS? Nobody knows. Science is the process of eliminating supernatural=20 explanations. The Higgs boson is the only elementary particle predicted b= y=20 the Standard Model of particle physics that has not yet been observed=20 experimentally. It=92s not for lack of trying. As Drew Baden points out, = the=20 $5 billion Large Hadron Collider has been rummaging through all the drawe= rs=20 in the house trying to find the Higgs. There's still one drawer they=20 haven't opened. They're getting ready to pry open the last drawer. THE UNIVERSITY OF MARYLAND.
