Hearing someone else's cell phone ring could cause changes in brain activity. Hearing someone scream into their cell hone could cause changes in brain activity. Thinking about buying a cell phone could cause changes in brain activity. | |

So accurate consideration of difference between quantum and classical sources may be important. | |

| Jul 10, 2011 at 4:38 | comment | added | Carl Brannen | When you talk about "single-photon" stuff you need quantum mechanics. Classical mechanics is restricted to the "multi-photon" domain. Example: Your microwave oven uses huge numbers of microwave frequency photons to heat your food. The fact that your food gets hot is a "multi-photon" effect. Putting your head in a microwave could kill you by overheating but it shouldn't cause cancer. On the other hand, no one has run the experiment. Maybe small amounts of localized heating causes cancer. Not by direct genetic change, but instead by, for example, harming the body's natural anti-cancer system. | |
