"One of the unfavorable results of the attempt to popularize science is
this: the reader of popular scientific books is very likely to think
that he understands the science itself, when he merely understands what
some writer says about science.
"Take, for example, the method of determining the distance of the moon
from the earth--one of the easiest problems in physical astronomy. The
method can be told in a few sentences; yet it took a hundred years to
determine it with any degree of accuracy--and a hundred years, not of
the average work of mankind in science, but a hundred years during which
able minds were bent to the problem.
"Still, with all the school-masters, and all the teaching, and all the
books, the ignorance of the unscientific world is enormous; they are
ignorant both ways--they underrate the scientific people and they
overrate them. There is, on the one hand, the Irish woman who is
disappointed because you cannot tell fortunes, and, on the other hand,
the cultivated woman who supposes that you must know _all_ science.
"I have a friend who wonders that I do not take my astronomical clock to
pieces. She supposes that because I am an astronomer, I must be able to
be a clock-maker, while I do not handle a tool if I can help it! She did
not expect to take her piano to pieces because she was musical! She was
as careful not to tinker it as I was not to tinker the clock, which only
an expert in clock-making was prepared to handle.
