Lesson 32-3 Galileo reborn 伽利略的复生
But can we blame those who looked and failed to see what Galileo saw, if we
remember that to use a telescope at the limit of its powers calls for long experience and
intimate familiarity with one's instrument? Was the philosopher who refused to look
through Galileo's telescope more culpable than those who alleged that the spiral nebulae
observed with Lord Rosse's great telescope in the eighteen-forties were scratches left
by the grinder? We can perhaps forgive those who said the moons of Jupiter were
produced by Galileo's spyglass if we recall that in his day, as for centuries before,
curved glass was the popular contrivance for producing not truth but illusion, untruth;
and if a single curved glass would distort nature, how much more would a pair of them?
