    A COLUMBUS OF SPACE (by Garrett P. Serviss. D. Appleton & Co., New York. Illustrated, $1.50) — This is a science-fiction tale for boys, written in Jules Verne’s fashion. He who is the hero of the story, by the power of ‘inter-atomic energy,’ sails into space in a queer airship he’s constructed, and with his companion lands on Venus. Then there is enough of lively action. Fierce giants with white saucer eyes and most beautiful Amazons, and monsters of the prehistoric sort, and dangers of several varieties, provide it. Boys will enjoy the story, which has four full page pictures in colors.

    By hard science fiction we mean that science fiction in which the story turns around a change in the environment that can be understood only scientifically and generally through what are known as the hard sciences, usually the laboratory sciences such as chemistry, physics, and biology, and the observational sciences such as astronomy, geology, and geography. Mathematics and computers are two of the tools used by all the hard sciences.
