FINDING THE SPEED OF LIGHT

THE 1676 DISCOVERY THAT DAZZLED THE WORLD

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.

Contentwise, an arbitrary assortment…but sure to draw fans of comics, of science, or of both.

FLASH FACTS

Flash, Batman, and other characters from the DC Comics universe tackle supervillains and STEM-related topics and sometimes, both.

Credited to 20 writers and illustrators in various combinations, the 10 episodes invite readers to tag along as Mera and Aquaman visit oceanic zones from epipelagic to hadalpelagic; Supergirl helps a young scholar pick a science-project topic by taking her on a tour of the solar system; and Swamp Thing lends Poison Ivy a hand to describe how DNA works (later joining Swamp Kid to scuttle a climate-altering scheme by Arcane). In other episodes, various costumed creations explain the ins and outs of diverse large- and small-scale phenomena, including electricity, atomic structure, forensic techniques, 3-D printing, and the lactate threshold. Presumably on the supposition that the characters will be more familiar to readers than the science, the minilectures tend to start from simple basics, but the figures are mostly both redrawn to look more childlike than in the comics and identified only in passing. Drawing styles and page designs differ from chapter to chapter but not enough to interrupt overall visual unity and flow—and the cast is sufficiently diverse to include roles for superheroes (and villains) of color like Cyborg, Kid Flash, and the Latina Green Lantern, Jessica Cruz. Appended lists of websites and science-based YouTube channels, plus instructions for homespun activities related to each episode, point inspired STEM-winders toward further discoveries.

Contentwise, an arbitrary assortment…but sure to draw fans of comics, of science, or of both. (Graphic nonfiction. 9-12)

What better way to make natural history slide down easily? (index) (Nonfiction. 8-10)

GET THE SCOOP ON ANIMAL SNOT, SPIT & SLIME!

FROM SNAKE VENOM TO FISH SLIME, 251 COOL FACTS ABOUT MUCUS, SALIVA & MORE

Cusick floats a slick, select gallery of nature’s spitters, nose-pickers, oozers, and slimers—most but not all nonhuman—atop nourishing globs of scientific information.

Title notwithstanding, the book is limited just to mucus and saliva. Following introductory looks at the major components of each, Cusick describes their often similar uses in nature—in swallowing or expelling foreign matter, fighting disease, predation and defense, camouflage, travel, communication (“Aren’t you glad humans use words to communicate?”), home construction, nutrition, and more. All of this is presented in easily digestible observations placed among, and often referring to, color photos of slime-covered goby fish, a giraffe with its tongue up its nose, various drooling animals, including a white infant, and like photogenic subjects. Two simple experiments cater to hands-on types, but any readers who take delight in sentences like “Some fungus beetles eat snail slime mucus” come away both stimulated and informed.
