"Since I have Ph. D. in Biophysics, I do not trust science overall. "
Very refreshing. And wise.
But the problem is not science; science as a commodity is pure.
The problem is scientists. Most scientists are not sufficiently skilled or sufficiently intelligent. They believe their own results without question when their methodology is faulty.
Every day we read findings by scientists that are clearly nonsense. Today, much of the rubbish arises from extrapolating global warming from inadequate data and, worse, then believing it. Worse still, the politicians believe it.
Out of many, many, the one I like best occurred about 15 years ago. It was predicted that within 35 years all the snow and ice on the Himalayas would melt. I wrote a letter to The Times saying that even if the entire Chinese nation went up there 24/7 with blowlamps, it would not happen.
