Quantum physics is more than a theory of atomic and subatomic particles and processes. It addresses the "nature of reality and the relationship between observer and observed. It represents nothing less than a complete transformation of our world view," heretofore firmly resting upon Newtonian physics.
In quantum mechanics, objects can be in more than one place at the same time. A particle can penetrate a barrier without breaking it. Something can be both wave and particle at the same time. Niels Bohr, a giant in early quantum theory, once remarked that anyone who is not shocked by quantum mechanics hasn't understood it.
The author describes his book in the preface, thus: "A quantum technology is a technology, which manipulates quantum probability amplitudes directly. This is now happening and some of the resulting technologies are described in this book." Chapter heading include Quantum Roulette, Atomic Calligraphy, Quantum Nano Circuits, and The Quantum Computer, each describes, as promised, the related quantum technology.
This book is not an introductory overview of quantum mechanics, and it omits the basic definitions and explanations that a reader new to the subject needs, in order to grasp the intellectual underpinnings of the book. It may be difficult for some. Therefore, students with the word "...Studies" in the description of their majors are excused. As the author states, Schrodinger's Machines deals with quantum technologies; it is not an explanation or a history of quantum mechanics. There are only two references in the index to Schrodinger's equations, and nothing at all about the man.
For the record, Erwin Schrodinger worked out the mathematics of quantum mechanics in 1925.
The book explains that in the world most people are familiar with -- the world of Newtonian physics -- there are no scientific doubts about where something is, and what momentum it has. These two quantities can be measured with precision.
However, in the world of quantum mechanics an idea such as precisely measuring things breaks down. There is an "uncertainty" associated with measurements, because whenever a measurement is made the system involved must be disturbed. This "uncertainty" leads to some strange things, even an inability to predict the location of a particle under study with 100% accuracy. There will always be a small probability that the particle will be some place else; that it can appear in places it has no right to be in, from the point of view of classical Newtonian physics.
Some people may conclude that this behavior of the physical universe sustains the views of literary deconstruction and New Age philosophy, which proclaim the absence of absolutes anywhere.
On the other hand, some people may conclude that this behavior of the physical universe sustains Voltaire's observation: "A watch betokens a watchmaker."
