A free undergraduate textbook on quantum theory, suitable for a first course.
We wanted to write an introduction for students who share our interest in the conceptual foundations of quantum mechanics. We think that for most students this approach not only makes learning more fun and engaging, it makes you grow up into better Quantum Mechanics.
