| Brave New World and the Good Old Days |
An unsigned editorial contrasting nostalgic enthusiasm for analog tools (slide rules, typewriters) with skepticism about contemporary environmental and scientific alarmism. Critiques the overconfidence of computer-based modeling in fields such as climate science and cosmology, arguing that models are constrained by their underlying assumptions. Stands as a philosophical counterweight to the technical articles in the same |

| Commitment—What It Takes |
An unsigned editorial on the planning and commitment required to write a major game for the Timex/Sinclair 2068. Discusses the machine’s memory constraints (39,826 bytes available), the design of a large 64×64 wrap-around world map for war and RPG games, estimated development time (~2,000 hours for the CONQUEST project), and the value of team programming. |

| The Future of Science and Mathematics |
An unsigned editorial arguing that theoretical science has become increasingly PC-aided and abstract, often disconnected from experimental verification. Discusses the controversy over the red shift and expanding universe theory, limitations of quantum mechanics and weather modeling, and the claim that mathematics itself is incomplete. Presents a skeptical view of computer-assisted theoretical work. |
