Thoughts On The Earth Sciences

Because i've been a collector of gemstones and a keen amateur lapidary for several years now, i've found myself drawn in the last few months to the meetings of the Field Geology Club of SA. In order to keep up I recently purchased an excellent book, "The Amateur Geologist" by Peter Cattermole. As illuminating as this book is it is the rear of the dust cover which has caused this enblogulation. On the back of the book it lists other books in the series, such as 'Amateur Astronomy', 'Naked-Eye Astronomy' and perhaps most intriguing of all 'The Practical Amateur Astronomer'.

This last book by its very existence posits the existence of the Impractical Amateur Astronomer. But what are the hallmarks of the impractical astronomer? Are they:
1. Blind
2. Allergic to telescopes
3. More than two connecting buses away from the nearest observatory
4. On fire
5. Werewolves

I include this last observation because the thing with werewolves has always been that they 'turn' when the moon is full, i.e. when the most light is being reflected from the lunar surface. It seems to me that if they were looking through a telescope at the moons of Saturn (for the purposes of example) they'd be getting a great deal of moonlight beamed straight into their eye. And that can't be good, really. Everyone else would get eaten, and that's not terribly practical at all.
