Scientific evidence

I have a small quibble with Neil deGrasse* Tyson’s statement in Cosmos:

In science, the only thing that counts is the evidence and the logic of the argument itself

Depending on the scientific pursuit in question, logic may have very much to very little if nothing at all to do with what the evidence shows. Biological research can sometimes fly in the face of logic. In my mind, the relative weight of logic to evidence follows a downward trajectory from physics to chemistry to biology to social and behavioral sciences.

The reason I point this out is that for many individuals not exposed to research or science on a deeper level than grade school and television, science can have the veneer of a logical endeavor. When faced with evidence that seems illogical to some, such as the enduring confusion around evolution, the tendency is to reject it on a basis of logic. So I would rephrase the above statement to say “In science, the only thing that counts is the evidence and that the evidence has been repeatedly and independently verified.”

*deGrasse is a recognized word in my browser’s dictionary

OMGZZ! Cell phones cause cancer!

Science!

No no no no no. This guy is a crank. The first thing he does is claim that the swine flu isn’t “real medicine.” And this is Fox News, where no facts are checked, ever. He cites an “increase in the incidence in brain cancer” as proof! Well, there is also an increase in the incidence of obesity, so maybe cell phones cause you to gain weight, too. Microwaves/radio waves are too long in wavelength to affect DNA. Longer wavelengths = lower frequency (ie, lower intensity). See the graph on this page.
Look at the size of the antenna on your phone (if your phone is from 1999) or radio. That’s the size of the wave, maybe a little smaller, but still nowhere near the intensity to affect DNA. They’re longer in wavelength than VISIBLE light. that would mean that your lightbulb causes even more cancer than your phone! The worst thing microwaves could do to the human body is warm it up. That said, don’t put your cat in the microwave.
