Lands with a dull thud despite being light on factual mass.

THE UPS AND DOWNS OF GRAVITY

How gravity works on things from apples to planets.

After an incorrect claim that Newton was “the first to describe gravity” (actually a topic of scholarly discussion since ancient times), Adler goes on to explain that mass is not the same as weight and to lay out the effects of distance between two attracting bodies. Expanding into the solar system he presents supposed weights for a 100-pound reader on Jupiter and the sun (omitting the fact that neither body has a surface that said reader could stand on). A confusingly incomplete introduction to orbital mechanics includes the notion of inertia—but never connects the Newtonian dots to explain why planets don’t move in straight lines. “There’s a lot more to gravity,” he vaguely remarks after all this, finishing in the same simplistic vein as he began by defining it as the force “that keeps everything in its place.” In Raff’s sparsely detailed pictures a mouse in a stereotypically schoolmarmish frock conducts two human children, one pale and the other brown-skinned, through various earthly and extraterrestrial scenes, pausing occasionally to let the children demonstrate physical principles or effects with balls, sheets of paper, and like common materials. Along with a richer (and funnier) visual experience, readers who fall into Jason Chin’s Gravity (2014) will ultimately touch down with a clearer understanding of how the phenomenon keeps people and planets in their courses.

A good overview of this complex, essential organ, with an energetic seasoning of silliness.

THE BRAIN IS KIND OF A BIG DEAL

An introduction to the lead guitar and vocalist for the Brainiacs—the human brain.

The brain (familiar to readers of Seluk’s “The Awkward Yeti” webcomic, which spun off the adult title Heart and Brain, 2015) looks like a dodgeball with arms and legs—pinkish, sturdy, and roundish, with a pair of square-framed spectacles bestowing an air of importance and hipness. Other organs of the body—tongue, lungs, stomach, muscle, and heart—are featured as members of the brain’s rock band (the verso of the dust jacket is a poster of the band). Seluk’s breezy, conversational prose and brightly colored, boldly outlined cartoon illustrations deliver basic information. The brain’s role in keeping the heart beating and other automatic functions, directing body movements, interpreting sights and sounds, remembering smells and tastes, and regulating sleep and hunger are all explained, prose augmented by dialogue balloons and information sidebars. Seluk points out, importantly, that feelings originate in the brain: “You can control how you react…but your feelings happen no matter what.” The parodied album covers on the front endpapers (including the Beatles, Pink Floyd, Green Day, Run DMC, Queen, Nirvana) will amuse parents—or at least grandparents—and the rear endpapers serve up band members’ clever social media and texting screenshots. Backmatter includes a glossary and further brain trivia but no resources or bibliography.

MARS! EARTHLINGS WELCOME

From the Our Universe series , Vol. 5

Good news! Planet Marvelous is looking forward to visitors from Planet Awesome.

With the same exuberance that propelled readers deep into her Ocean! Waves for All (2020), illustrated by David Litchfield, and its three predecessors in the Our Universe series, McAnulty looks to the next planet out for a fresh set of enticing natural wonders. Billing itself a “party planet” (“I want to be the FIRST planet with human guests”), the russet raconteur trumpets its unique attractions. These range from moons Deimos and Phobos (“I know Earth is totally jealous”) to Olympus Mons and Valles Marineris, which is “four times as deep as the Grand Canyon! And not nearly as crowded.” Sure, unlike Spirit, Opportunity, and other rovers, human visitors will have to pack their own water and oxygen in addition to traveling millions of miles…but given a few technological advances, soon enough it’ll be time to “get this party started!” Prospective tourists diverse of age and race are dancing already on Earth in a final scene in anticipation of a trip to our “reMARkable” neighbor. Quiz questions and a timeline cap an enticement that echoes Susanna Leonard Hill’s Mars’ First Friends: Come on Over, Rovers! (2020), illustrated by Elisa Paganelli, in its fizzy mix of fact and fancy. (This book was reviewed digitally with 10-by-20-inch double-page spreads viewed at 75% of actual size.)
