Wave-particle duality, Schrödinger’s cat, the uncertainty principle, non-locality, instantaneous action-at-a-distance, a roll-the-dice universe—there are many mysterious ideas in quantum mechanics. A clear understanding of these ideas and their implications is given here.
The site is intended for both scientists and non-scientists. The main text is written for non-scientists, with an emphasis on clarity, while the more technical supporting arguments are given in appendices.
What makes our approach different? There is a set of principles that can be deduced from our ordinary perceptions of the world plus the mathematics of the theory. (These are stated in plain, non-mathematical language.) In other treatments, the power of all these principles together is not fully exploited. If you look at their cumulative implications, however, you find they eliminate most of the mysteries connected with quantum mechanics. Wave-particle duality, Schrödinger’s cat, the uncertainty principle, the double slit experiment, and non-locality all become clearly understood.
The principles have far-reaching consequences. They show beyond doubt that there is currently no support in physics for scientific materialism—the belief that all that exists is this familiar physical world. Further, the principles imply that physics as it currently stands is incomplete; to complete it we must assume our awareness originates outside the physical brain, outside the physical universe.
To become familiar with the most basic ideas of quantum mechanics, it is best to start with section 1, Introduction to Understanding Quantum Mechanics. A list of all the physics sections is given at Physics on the navigation bar.
