How the observation of a small anomaly in a distant moon's orbit led to a discovery of, literally, astronomical significance.Weston spins thin historical records into an account of the career of 17th-century Danish astronomer Ole Romer from schoolboy days through nights spent watching the skies through a self-built telescope at the court of Louis XIV to final years as a renowned scientist (and police chief). Noticing that Jupiter's moon Io seemed to speed up and slow down on a regular schedule as it passed behind its planet, Romer not only concluded that light did not propagate instantaneously (a radical notion then), but, using the relatively crude clocks and other instruments of the time, came up with a wrong but close estimate of its speed. Along with retracing Romer's line of reasoning, the author explains how other researchers of the time and later roughed out the distances between major members of the solar system and refined those measurements over time, then closes with nods to Einstein, astronomical distances, and light's truly mind-bending pace. Evans tucks diagrams and mathematical calculations as well as banter and fanciful details into her lighthearted cartoon illustrations, wedging single and sequential panels of Romer and others at work into views of starscapes and planetary surfaces. Human figures in the art are white and predominantly male.A significant, unjustly obscure highlight from modern science's early days.

Gr 3--5--Ole R'mer was a young Danish scientist in 1676 working for a French astronomer when he made the remarkable discovery that the appearance of light is not instantaneous; light actually moves and has a speed. It all started with his fascination with Io, one of Jupiter's moons, and his observations that Io's orbit seemed to slow down every now and then. Through careful and intricate math calculations, R'mer eventually realized that Io wasn't slowing down; rather, the light from Io was taking longer to reach Earth because of its uneven orbit. This book includes a lot of text, and the narrative occasionally meanders, making it confusing to follow. Speech bubbles sometimes complement the story of R'mer and the scientists with whom he worked, and sometimes focus on facts or explanations, adding to the inconsistent feel. Descriptions of scientific and mathematical concepts are detailed and fairly complicated. The lovely watercolors are full of washes of blues and deep purples, fitting the subject. Back matter includes a brief time line and an afterword that extends some of the ideas from the book, but there is no bibliography or further reading list. VERDICT Beautiful illustrations and an intriguing idea are counterbalanced with complex concepts and uneven pacing, making this a secondary purchase for most libraries.--Jody Kopple, Shady Hill School, Cambridge, MA

Growing up in seventeenth-century Denmark, Ole Romer wondered why lightning appeared before thunder sounded. Later, as an astronomer in Paris, Romer's observations of Jupiter's moon (Io) led him to calculate the speed of light. Dense scientific information is lightened by comic-panel illustrations with speech-bubble jokes about ice cream, plumbing, and butts. Budding scientists will enjoy learning the slow process of scientific discovery. Timeline. (c) Copyright 2019. The Horn Book, Inc., a wholly owned subsidiary of Media Source, Inc.
