In the lantern-lit lanes of Quantum Bazaar, an eight-year-old girl named Quanta finds a small brass coin that refuses to behave. It is neither heads nor tails, not until she looks. That single moment of looking opens the door to the strangest and most wonderful idea in all of science: superposition.Guided by her grandmother Dadi-Bot, her quick-witted cousin Arjo, two sleepy little qubits, and a wise old temple cat, Quanta sets out to understand how something can be two things at once. Along the way she learns that the universe hides its biggest secrets in its smallest places, and that asking a question can change the answer.Warm, funny, and gently mind-bending, Quanta and the Two-State Coin is a first picture book about quantum physics for curious children aged 5 to 9. It turns a famously difficult idea into a story families can read aloud together, set in a richly illustrated Indian world that feels both magical and real.This 24-spread adventure also includes fun facts, try-this-at-home demonstrations, a quiz, a maze, and a colour-me page, so young readers can keep playing with the ideas long after the story ends.Book 1 of the Quantum Bazaar Series: the perfect first step into quantum thinking for the scientists, dreamers, and question-askers of tomorrow.
