[edit] Introduction
Quantum mechanics is the last of the big branches of physics. Start at the beginning of the twentieth century, at the time that two of the theories attempting to explain what surrounds us, the law of universal gravitation and classical electromagnetic theory, became insufficient to explain certain phenomena. Electromagnetic theory generated a problem when trying to explain the emission ofconsequences for an undisclosed sum to obtain continuous left an infinite result, which eliminated the problem and, moreover, the result was consistent with what later was measured. It was Max Planck who then enunciated the hypothesis that electromagnetic radiation is absorbed and emitted by matter in the form of light quanta or photons of energy through a statistical constant which is called Planck's constant. His story is inherent in the twentieth century, as the first formulation of a quantum phenomenon was issued on December 14, 1900 at a meeting of the Physical Society of the Academy of Sciences in Berlin by the German scientist Max Planck. [3 ]

Planck's idea had been for many years as a hypothesis only if Albert Einstein had not taken up by proposing that light, in certain circumstances, behave as independent particles of energy (light quanta or photons). It was Albert Einstein who in 1905 completed the relevant laws of motion to what is known as the special theory of relativity, showing that electromagnetism was essentially non-mechanics theory. Thus ended what has been called classical physics, ie non-quantum physics. He used this view as he calls it "heuristic" to develop his theory of photoelectric effect. This hypothesis published in 1905 and earned him the Nobel Prize in 1921. This hypothesis was applied also to propose a theory of specific heat, ie it solvesand which is the amount of heat needed to raise the temperature by one unit mass of a body.

speeds of the constituent particles must not be too high, or close to the speed of light.

quantum mechanics breaks any paradigm of physics at that moment, she discovers that the atomic world does not behave as we would expect. The concepts of uncertainty, uncertainty or quantization are first introduced here. In addition quantum mechanics is the scientific theory that has provided the most accurate experimental predictions so far, despite being subject to the odds.

formal development of the theory was the work of the joint efforts of several physicists and mathematicians of the time as Schrödinger, Heisenberg, Einstein, Dirac, Bohr and Von Neumann and others (the list is long). Some of the key aspects of the theory are still being actively studied. Quantum mechanics has also been adopted as the underlying theory to many fields of physics and chemistry, including condensed matter physics, quantum chemistry and particle physics.

The region of origin of quantum mechanics can be located in central Europe, Germany and Austria, and the historical contextnergy behaves as a continuum.
Although the formal structure of the theory is well developed, and their results are consistent with experiment, not so with its interpretation, which remains controversial.

[edit] Description of the theory under the Copenhagen interpretation
to describe the general theory requires a rigorous mathematical treatment, but accepting one of the three interpretations of quantum mechanics (from now on the Copenhagen Interpretation) The framework is relaxed. Quantum mechanics describes the instantaneous state of a system (quantum state) with a wave function that encodes the probability distribution of all measurable properties, or observablemind as a particle that surrounds the nucleus, whereas in quantum mechanics is described by a static probability cloud surrounding the nucleus.

When performing a measurement on an observable system, the wave function becomes a set of functions called eigenstates or eigenfunctions of the observable in question. This process is known as collapse of the wave function. The relative probabilities of the collapse of one of the possible eigenstates is described by the instantaneous wave function just before the reduction. Considering the earlier example of the particle in the vacuum, measured in the same position, you will get an unpredictable value x. In general, it is impossible to predict with precisionn what value of x is obtained, although it is likely to get one near the center of the wave packet, where the amplitude of the wave function is large. After that has been done so far, the wave function collapses and the particle is reduced to one that is very concentrated around the observed position x.

Schrödinger equation is partly deterministic in the sense that, given a wave function to a given initial time, the equation provides a specific prediction of what will function at any later time. During a measurement, the eigen-state which is probabilistic function collapse and in this respect is not deterministic. So the probabilistic nature of quantum mechanics arises from the act of measurement. CHTM
ad of an observable in a given state by computing the spectral decomposition of the corresponding operator. The Heisenberg uncertainty principle is represented by the assertion that the operators corresponding to certain observables do not commute.

[edit] Relativity and quantum mechanics
The modern world of physics is based substantially on two main theories, general relativity and quantum mechanics, although both theories seem to contradict each other. The assumptions that define the theory of relativity of Einstein and quantum theory are indisputably supported by rigorous and repeated empirical evidence. However, both are reluctant to be incorporated into a single coherent model. The

Einstein himself is known for rejecting some of the demands of quantum mechanics. Despite being clearly resourceful in their field, Einstein did not accept the orthodox interpretation of quantum mechanics such as the assertion that a single subatomic particle can occupy several spaces at once. Einstein did not accept the consequences of even more exotic quantum entanglement of the Einstein-Podolsky-Rosen (or EPR), which shows that measuring the state of one particle could instantaneously change the state of his partner bound, although the two particles can be an arbitrary distance. However, this effect does not violate causality, since there is no possible transfer of information. In fact, there are theories cuinit.d that incorporate special relativity, for example, quantum electrodynamics, which is currently under proven physical theory, and these are in the same kidney of modern particle physics.
