Enjoy five enchanting journeys in one volume-the four beloved Ruth adventures you know and love, plus an all-new, never-before-released story available only in this special collection!
The Adventures of Ruth the Scientist
Tucked inside Grandma's blossoming Victorian garden, six-year-old Ruth asks questions as big as the universe itself-and her glowing firefly tutor Professor Photon is always ready with a spark of wisdom. Together they turn marbles, pond water, and starlight into gateways to quantum mysteries, cosmic clocks, and everything between.
Ruth Learns Relativity Special relativity
Toy-rocket races teach that clocks stretch, rulers shrink, and nothing outruns light's speed limit.
Ruth and the Quantum Tunnel Quantum tunneling
A marble won't go over or under a brick wall-until it goes straight through. Ruth learns tiny things can cross barriers no marble should.
Ruth and the Missing Ball Quantum superposition & uncertainty
Her favorite red bouncy ball vanishes-could it be in two places at once? Ruth discovers a particle can be "here and there" until measurement makes it choose.
And one book that has only been released in this collection:
Ruth's Wiggly Waves Schrödinger's Equation
Glowing teal (psi, prounounced ssigh) ψ-ribbons drape over sandbox hills (potentials V(x)), revealing how wave wiggles and energy E choreograph a particle's "maybe dance."
Why Kids (and Grown-Ups) Love Ruth
Hands-on labs in every book - map pond waves, build sand-hill potentials, craft ψ-ribbons, and stage quantum hide-and-seek.
Big-Idea sidebars - crystal-clear nuggets that keep the physics precise while the wonder stays huge.
Watercolor warmth - soft Victorian palettes, playful pencil lines, and a signature teal glow that threads every adventure together.
History meets STEM - corsets and cobblestones share pages with rocket math and quantum magic.
Ideal for ages 6-10, perfect for classroom STEM corners, family read-alouds, and every young explorer who knows imagination is the spark and curiosity the compass-everything needed to journey from a garden pond to the furthest stars.
