An interesting account of lunar history and exploration by remote control covers theories of origin and the various interpretations of lunar formations we can see through strong telescopes today. Two opposing theories of origin are George Darwin's which maintains that the moon was a big blob of lava that broke from the earth, and Von Weizsacker's, which holds that it is a collection of travelling space particles. This absorbing kind of controversy continues through the discussion of the formation of seas, craters, mountains and seas. An imaginary trip to the moon tops it off.
