PREFACE of Quantum Mechanics for Scientists and Engineers by David A. B. Miller:
This guide introduces quantum mechanics to scientists and engineers. It may be used as a textual content for junior undergraduates onwards by means of to graduate college students and professionals. The extent and strategy are aimed toward anybody with an inexpensive scientific or technical background trying for a strong however accessible introduction to the topic.
The protection and depth are substantial sufficient for a primary quantum mechanics course for physicists. On the identical time, the extent of required background in physics and arithmetic has been stored to a minimal to swimsuit these additionally from different science and engineering backgrounds.
Quantum mechanics has lengthy been important for all physicists and in different bodily science topics akin to chemistry. With the rising curiosity in nanotechnology, quantum mechanics has not too long ago develop into more and more necessary for an ever-widening vary of engineering disciplines, akin to electrical and mechanical engineering, and for topics akin to supplies science that underlie many trendy units.
Many physics college students additionally discover that they’re more and more motivated within the topic because the on a regular basis functions develop into clear. Non-physicists have a selected downside to find an acceptable introduction to the topic.
The everyday physics quantum mechanics course or textual content offers with many matters that, although essentially fascinating, are helpful primarily to physicists doing physics; that selection of matters additionally means omitting many others which are simply as really quantum mechanics, however have extra sensible functions.
Too typically, the result’s that engineers or utilized scientists can not afford the time or can not maintain the motivation to observe such a physics-oriented sequence. Consequently, they by no means have a correct grounding within the topic. As a substitute, they choose up bits and items in different programs or texts.
Studying quantum mechanics in such a piecemeal strategy is particularly tough; the scholar then by no means correctly confronts the various essentially counterintuitive ideas of the topic. These ideas have to be understood fairly deeply if the scholar is ever going to use the topic with any reliability in any novel scenario.
Too typically additionally, even after working laborious in a quantum mechanics class, and even after passing the exams, the scholar continues to be left with the miserable feeling that they don’t perceive the topic in any respect. To deal with the wants of its broad meant readership, this guide differs from most others in 3 ways.
First, it presumes as little as potential in prior data of physics. Particularly, it doesn’t presume the superior classical mechanics (together with ideas akin to Hamiltonians and Lagrangians) that’s typically a prerequisite in physics quantum mechanics texts and programs.
Second, in two background appendices, it summarizes the entire key physics and arithmetic past the high-school degree that the reader wants to begin the topic. Third, it introduces the quantum mechanics that underlies many necessary areas of software, together with semiconductor physics, optics, and optoelectronics.
Such areas are normally omitted from quantum mechanics texts, however this guide introduces most of the quantum mechanical ideas and fashions which are exploited in these topics. It’s also my perception and expertise that utilizing quantum mechanics in a number of completely different and sensible areas of software removes most of the difficulties in understanding the topic.
If quantum mechanics is just illustrated by means of examples which are discovered within the extra esoteric branches of physics, the topic itself can appear irrelevant and obscure. There’s nothing like designing an actual gadget with quantum mechanics to make the topic tangible and significant.
Even with its intentionally restricted stipulations and its elevated dialogue of functions, this guide affords a strong basis within the topic. That basis ought to put together the reader properly for the quantum mechanics in both superior physics or in deeper examine of sensible functions in different scientific and engineering fields.
