Quantum Mechanics, Strange or Not

Do quantum objects have wave-particle duality? Can states be superimposed, remotely entangled, present uncertainty, and even open multiple worlds? Can Schrödinger's cat really be alive and dead at the same time? Or does the quantum world only exist under human observation? … Bohr, Feynman, Heisenberg, Schrödinger, Einstein... Are these great physicists also making mistakes? ——Then why are they still great? Various quantum "theories" are still very strange so far, and they are still lacking in explanatory power and self-consistency, but this is not a problem of the quantum world "itself". Humanity's understanding of the quantum world has indeed been improving over the past century: we can optimistically say that although there is still a long way to go, we are getting closer to the "truth" little by little. Through this book, you will have an overview of the century-old history of the development of quantum mechanics theory. Standing on the shoulders of scientific giants and exquisite theories, you will have a better understanding of the quantum world and have more practical, reasonable and hopeful expectations for the prospects of quantum theory applications such as "quantum computers".
