Gravity isn't just a good idea. It's the law

What happens when a falling apple turns into a universe-sized question?
In this laugh-out-loud kids science adventure book, Calvin and his loyal (and frequently confused) beagle Pudge stumble into an unforgettable encounter with Isaac Newton — and discover that gravity isn’t just something that makes apples fall. It’s the invisible force shaping oceans, guiding orbiting moons, moving entire planets, and even collapsing distant stars.
Blending humor, heart, and big ideas, Calvin and Pudge Meet Isaac Newton transforms complex scientific concepts into an unforgettable children’s STEM fiction adventure. Through runaway carts, drifting feathers, rising tides, and late-night telescope discoveries, young readers experience gravity explained for children in a way that feels exciting, approachable, and deeply meaningful.
This educational historical fiction for kids introduces one of history’s greatest thinkers while keeping the story playful, character-driven, and full of the curiosity that defines the Calvin & Pudge universe. Instead of memorizing facts, readers learn how to ask better questions — and why asking “why?” is the beginning of every great discovery.
Perfect for:
STEM-curious readers ages 7–12
Families looking for funny science books for middle grade
Parents who want educational fiction that doesn’t feel like homework
Teachers and homeschool families seeking a creative homeschool science supplement
Classrooms introducing Isaac Newton for kids in a story-based format
This isn’t just a book about gravity.
It’s a story about curiosity.
About structure.
About discovering that the universe follows laws — and that understanding those laws gives us the confidence to explore it.
Because gravity isn’t just a good idea.
It’s the law.
