quantum mechanics Yanyi first discusses the theoretical framework of quantum mechanics, including the main target, the basic method and the similarities and differences with classical mechanics, experimental observation and the common laboratory can be realized as an example, the necessity of the quantum effect of universal significance and applications of quantum mechanics.On this basis, followed by the introduction of the density matrix, relativistic wave equation, the path integral, the two quantization method, quantum field theory, the electromagnetic field of the quantum effect and quantum scattering theory.The theoretical part of the quantum field, basic thoughts and methods about canonical quantization of the electromagnetic field; and quantum effects of a chapter, in addition to the canonical quantization of the electromagnetic field, the basic theoretical framework of quantum electromagnetic field and electron field interaction and the method of dealing with specific problems, it is the foundation of quantum electrodynamics and quantum optics.
Quantum mechanics can be used as the physical meaning of high grade undergraduate or graduate “ higher quantum mechanical ” curriculum or teaching reference books, but also can be used as mathematics, chemistry, materials and biology graduate teaching reference book.

Summary
The first chapter taste of quantum mechanics, Confucius said: "learning without thought is labor lost, thought without learning is perilous."The initial study "quantum mechanics" course, many people feel "cannot see the wood for the trees", and that the quantum effect is very far away, only in the sophisticated laboratory can be observed in the subtle effect.This is "learning without thinking" or "learning and thinking" to "lost".Unlike the intuition of classical mechanics, quantum mechanics into the matter wave, mechanical quantity operator concept, cause physical particle motion trajectory, no energy quantization of angular momentum phenomenon.These seemingly "mysterious" concept, so that beginners can't intuitive analogy and analysis of the quantum motion, it is difficult to form the theoretical framework of simple in thought, so leave the quantum mechanics textbooks will feel a loss.Although, clever student can handle a variety of quantum mechanics, but the actual quantum problems are not start, the more difficult to put quantum problems, as for the physics behind the taste of quantum mechanics, namely guess to overtones, is very rare.If things go on like this, studying quantum mechanics became a chore, rumors "quantum mechanics quantum mechanics", many people even put "advanced quantum mechanics" belong to "mumbo-jumbo".In fact, the quantum effect on our side, this book you face can be described as a quantum of identical particle system, quantum effects will cause the fading; interaction in common laboratory spectral measurement, laser with atoms and molecules, are related to the obvious quantum effect, must use the quantum mechanical description of movement to electronic are in agreement with the experimental observations.If often think about the similarities and differences between quantum mechanics and classical mechanics and daily experience and modern technology, can understand quantum theory.We should pay attention to quantum mechanics, which belongs to the category of theoretical physics, theoretical physics is simple and the broad and profound, is enough to make the perceived as "son Qi hydraul ic, absorbed".Therefore, to see quantum mechanics, taste it, establish a clear framework, also need to understand the basic characteristics and the brilliant achievements of theoretical physics.Seems to be characteristic of the 1.1 classical mechanics and quantum mechanics quantum mechanics can be used "Xuan, wonderful, difficult to" three words sum up.The so-called "black", namely mechanical quantity of operator, system state to the Yu Bo function, and the experimental personnel can only observe the system "allowed" intrinsic value.Regardless of whether you accept the "mysterious" Nian, people have opened the microscopic world and the material world of quantum mechanics, and is predicted to be verified by experiment and wonderful phenomena or singular existence, Yang Bojun.2006. the interpretation of Analects of Confucius. Beijing: Zhonghua Book company.Quantum mechanics is described as "wonderful".Compared with the Newtonian mechanics, quantum mechanics, the mathematics involved is complex, but not difficult."Difficult" is chiefly because no framework for understanding quantum theory, I do not know of mathematical inference goal, therefore there is no calculus of motivation, also won't go to the practice of mathematical deduction.In fact, relative to the logical thinking, mathematical deduction in physics involves more easily, because it is "water logic mechanization", as long as you do it on the line.So as long as the "black", the "wonderful", "hard" would be nothing difficult."Mysterious" is not just limited to modern physics, it is a universal cultural phenomenon.In the traditional Chinese culture of "Xuan" read: "Yin, Yang", "the network, the former without measure," meaning, the latter no anatomical entity, however the formation of Yi logic in "Yin, Yang" basis, to "after, network" as the clue of the development of TCM theory.Some people say that compared with western medicine, Chinese medicine have no effect.
So mysterious, is attractive charm.If all the movement of objects like a pendulum that simple reciprocating, don't you feel boring?And the task we are deeply convinced of the correctness of 1.1.1 method of Newton's three law, so when the Newton's second law applies to your pen it established?No.You take the quality into the air for 10G pen throw, applying 1N along the horizontal direction to the end of the penholder A force, then the measurement of horizontal acceleration A end, it must be greater than the value obtained by the second law of Newton.Remember, F.= Ma set up only on the particle.The so-called particle, is a quality without volume "mysterious" concept, it is Newton "invented" clash with everyday experience "monster".And it is this "mystery" Nian, enable Newton to describe movement is the most delicate planet, can answer his age all the scientific mystery.Classical mechanics is a macroscopic physical object considered consisting of a plurality of particle system S, the description method of the system is determined for each particle position vector R.I and the corresponding speed of V.I, which can get the mechanical properties of system energy, momentum, angular momentum and all.There are 3 other completely different description methods for the same system of S, such as the thermodynamic method of describing the system pressure, volume and temperature first physical quantities.Compared with the classical mechanics description, number variable thermodynamic method involves a lot less, do not contain microscopic chapter structure information, but can easily get lots of useful information on the macroscopic physical system.For example, using the principle of increase of entropy and free energy criterion shows the system should develop to produce a material in the direction of A, although Conghua reaction channels, generate other substances B, C is also possible.......
