This book uses a new approach distinct from conventional quantum mechanics popularizations, connecting and explaining fragmented and disorganized knowledge points in a more natural, elegant, and easily comprehensible way, constructing a coherent knowledge framework. It dispels some of the public’s common misconceptions about quantum mechanics and allows readers to understand quantum mechanics from a higher level and different angle. It helps you establish an analytical framework for quantum mechanics from scratch, enabling secondary school students to view problems from a quantum perspective. You will find that those strange quantum phenomena are actually quite natural, and you, too, can understand quantum mechanics.
