Quantum Mechanics: A Comprehensible Introduction for Students [New Edition with Readable Equations]

Quantum mechanics is full of mysteries and paradoxes. It has even been regarded as the most difficult subject to understand. The main reason is that unlike classical mechanics, quantum mechanics provides no visualizable spatial-temporal images for the physical processes it describes. It is well understood that classical mechanics describes the continuous motion of particles in space and time. In quantum mechanics, however, it is still unclear how microscopic particles such as electrons move in space and time, and in fact, it is even unknown whether these microscopic particles are really particles or not.

Based on a penetrating analysis of the wave function and its evolution, this book presents a new, comprehensible formulation of quantum mechanics. It turns out that, like classical mechanics, quantum mechanics also deals with the motion of particles in space and time. The difference only lies in that the former describes continuous motion of particles, while the later describes random discontinuous motion of particles. Microscopic particles such as electrons are indeed particles, but they move in a discontinuous and random way. For example, a single electron passes through two slits at the same time in a discontinuous way in the double-slit experiment with electrons.

If you are not wholly satisfied with the quantum mechanics as “explained” by textbooks, and if you still keep your curiosities and want to know what the most fundamental theory really means, then this book is for you. After reading it, you may find quantum mechanics is no longer mysterious. If you can understand classical mechanics, you will be able to understand quantum mechanics too.
