Jesse L. Greenstein quotes:

Knowing how hard it is to collect a fact, you understand why most people want to have some fun analyzing it.

At the age of three I began to look around my grandfather's library. My first knowledge of astronomy came from reading and looking at pictures at that time. By the time I was six I remember him buying books for me. ... I think I was eight, he bought me a three-inch telescope on a brass mounting. ... So, as far back as I can remember, I had an early interest in science in general, astronomy in particular.

In a sense Shapley's telling me that space was transparent, which I shouldn't have believed, illustrates a fundamental problem in science, believing what people tell you. Go and find it out for yourself. That same error has persisted in my life and in many other people's. Authorities are not always authorities on everything; they often cling to their own mistakes.
