It's been a century since quantum mechanics and Einstein's Theory of Relativity were conceptualized. Some aspects of Q.M and Relativity still haven't been well considered or well presented to the public. We're about due for another revolutionary advance in our understanding of these theories that describe the foundations of the Universe. We're hearing about quantum computing, quantum memory, quantum multiple realities, and other emergent topics of quantum theory. The public, as well as scientists, would do well to glean a heads-up understanding on these concepts now, before the next dam bursts. This book explains the fundamentals of quantum mechanics 101 to a popular audience in an interesting way. It explores the history and philosophy of quantum mechanics, going back to the original "dual nature" experiment in the early 1800's. It explains in popular terms the great debates between Albert Einstein, who was skeptical of quantum theories, and Q.M.'s founders, like Niels Bohr. These debates go to the core of the realities we experience. We'll begin our exploration of quantum mechanics by wrapping it around a science fiction experiment that purports to prove or disprove quantum immortality, i.e. the permanent retention of the information we acquire in life.
