The Popular Science Monthly, July, 1900 Vol. 57, May, 1900 to October, 1900

A vivid snapshot of scientific life at the turn of the 20th century, this collection opens with Professor Simon Newcomb’s “Chapters on the Stars,” a lively tour of the daring expeditions that finally charted the southern heavens. Newcomb recounts the work of Halley, Lacaille, Herschel and others, showing how modest observatories in far‑flung locales turned vague curiosity into precise stellar maps. The narrative blends adventure with the painstaking detail of early astronomical technique, making the past feel almost tangible.

The volume then swings far beyond the night sky, offering short yet thorough pieces on topics such as preventive inoculation, the chemistry of Earth’s development, and the latest discoveries in X‑ray and artificial light. Readers will also hear about MIT’s technical education, the psychology behind popular fads, and a contemporary report on the May 28, 1900 solar eclipse. Together, these essays provide a concise, engaging tour of the era’s most pressing scientific questions and achievements.
