"The next two books in the Baby Loves series tackle the first law of thermodynamics (energy cannot be created or destroyed, but it can change forms) and Schrd̲inger's Cat, the famous thought experiment involving quantum theory (quantum physics states that a particle can exist in multiple places at once). Accurate enough to satisfy an expert and simple enough for the rest of us to comprehend, the Baby Loves board books are perfect for geeky moms and dads who want to share their love of science, for parents who want to give their infant a head start on Harvard, and for hipster aunts and uncles who want that oh-so-clever gift for the baby shower."-- Provided by publisher.
