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.

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 certain sense I made a living for five or six years out of that one star [υ Sagittarii] and it is still a fascinating, not understood, star. It's the first star in which you could clearly demonstrate an enormous difference in chemical composition from the sun. It had almost no hydrogen. It was made largely of helium, and had much too much nitrogen and neon. It's still a mystery in many ways ... But it was the first star ever analysed that had a different composition, and I started that area of spectroscopy in the late thirties.
