 The ITER Project

Years from now—maybe in a decade, maybe sooner—if all goes according to plan, the most complex machine ever built will be switched on in an Alpine forest in the South of France. The machine, called the International Thermonuclear Experimental Reactor, or iter, will stand a hundred feet tall, and it will weigh twenty-three thousand tons—more than twice the weight of the Eiffel Tower. At its core, densely packed high-precision equipment will encase a cavernous vacuum chamber, in which a s...

 Why Cell Phone Radiation Does Not Cause Cancer

Physics explains why no links were found. The microwaves used in cell phone transmissions do not have enough energy to break the chemical bonds of DNA, which is how cell mutations occur and cause cancer. How do we know this? Light and other parts of the electromagnetic spectrum, including microwaves, radio waves, infrared waves, and ultraviolet light waves, are all forms of radiation. A single unit of radiation is called a photon. A photon can be thought of either as a particle or as a wave. ...
