rather ordinary materials. It is for such an amateur that this book is meant. We shall only consider Newtonian reflecting telescopes of large focal ratios using simple altazimuth or german equatorial mounts. We shall not discuss parabolizing of mirrors‚ the construction of Cassegrainians‚ the design of telescope drives etc. These pages would have served their purpose if they encourage beginners to construct simple telescopes for sight seeing the skies. If they make this important beginning it is

Non-superimposable Mirror Images • Although everything has a mirror image‚ mirror images may or may not be superimposable. • Some molecules are like hands. Left and right hands are mirror images‚ but they are not identical‚ or superimposable. • A molecule (or object) that is not superimposable on its mirror image is said to be chiral.
