"This is a wonderfully written, scientifically sound, and beautifully illustrated book that helped me introduce some mind-bindingly awesome concepts to my four-year-old. Science is like magic, but real." - Anthony V., former 7th and 8th grade physics teacher. The first in a series of IMAGINE SCIENCE storybooks for kids! Introducing the wonders of science with this easy to understand exploration into general relativity that begins on a backyard trampoline. Join Finn + Remy as their simple ball game takes a frustrating turn and papa's explanation does not quite make sense. To answer their question, the trio (plus chicken in a clever disguise) launch into space as astronauts to discover the effects of mass on gravitational forces. The juxtaposition of Earth and moon provides the explanation. Lit against a backdrop of stars and planets in our solar system, this beautifully illustrated book will take you on a cosmic adventure full of imagination. For ages 4-10. The two adorable hedgehog characters are based on real boys bearing the same names created by an inspired mom with an artsy streak and a husband who was a scientist in his previous life. Together, they have pressed pause on the American Dream and are traveling the world to write books they want their children to read.
