Along the way...

A reader, who clearly didn't care

for columns devoted to science,

said, "You know, science gets

things wrong." She was, of course,

correct. Science does get things

wrong sometimes. The difference

between science and opinion

though, is when science is shown

to have made a mistake it seeks

to correct the mistake rather than

digging in its heels and defending

the indefensible.

An example of scientific

methodology was observation of the

planet Uranus, discovered in 1781.

As scientists studied it they became

aware that something was wrong.

It was not behaving in accord

with Newton's Law of Gravity....
