'Settled science' chronicles

Thomas Lifson
There is no such thing as "settled science." All scientific theories are subject to testing and falsification by new data and theories. The latest example: static electricity. Devin  Powell writes in Science News:

A balloon rubbed against the head can be both a hair-raising and a hair-tearing experience, a new study suggests. Clumps of balloon and hair invisible to the naked eye may break off each object during contact and stick to the other.

The existence of this exchange could challenge traditional theories about how static electricity builds up, a process known as contact electrification.

"The basic assumptions people have made about contact electrification are wrong," says Bartosz Grzybowski, a physical chemist at Northwestern University in Evanston, Ill. He and his colleagues describe their new take on static electricity online June 23 in Science.

Anyone who dismisses challenges to a theory on the ground that the science is settled is either a dupe or a fraud.
