This open access book develops the world of quantum physics without requiring the onerous math prerequisites of all other texts. Rather than taking just a descriptive approach, or the conventional higher-math approach, this book develops rigorous quantum mechanics beginning at the level of a nonscientist. It is appropriate for advanced high-school students, lifelong learners, citizen scientists, undergraduate students, graduate students, and even current practitioners, engaging a wide group of topics that require no math beyond high-school-level algebra, trigonometry, and geometry.
