What is the quantum mechanics

Under quantum mechanics to understand the dynamic behavior of the physical theory of forms of radiation and matter.This is the theoretical foundation on which is built the modern theory of atomic nuclei, atoms, physical bodies, molecules and elementary particles.Generally, quantum mechanics was created by scientists who sought to understand the structure of the atom.For many years the legendary physicists studied the characteristics and direction of chemistry and followed the historical time of events.

such thing as quantum mechanics, infancy for years.In 1911, scientists Bohr and Rutherford proposed a nuclear model of the atom, which resembled the Copernican model of the solar system with it.After the solar system had at its center a nucleus around which the rotating member.On the basis of this theory began calculating physical and chemical properties of some substances that were built from simple atoms.

One important issue in this theory as quantum mechanics - is the nature of the forces that bound atom.Due to Coulomb's law, Rutherford showed that this law is just a huge scale.Then it was necessary to determine how the electrons move along its orbit.At this point, it helped Newton's law.

In fact, quantum mechanics often contrary to concepts such as common sense.Along with the fact that our common sense acts and shows only those items that can be taken from everyday experience.And, in turn, everyday experience only deals with the phenomena of the macrocosm and large objects, while the particles of matter at the subatomic and atomic level behave quite differently.For example, in the macrocosm we are able to easily determine the presence of any object using the instrumentation and methods.And if we measure the coordinates of the electron microparticles then neglect the interaction of the measurement object and the measuring device is simply unacceptable.

other words we can say that quantum mechanics a physical theory, which establishes the laws of motion of different microparticles.From classical mechanics, which describes the motion of microparticles, quantum mechanics characterized by two parameters:

- the likely nature of some physical quantities such as speed and position of the microparticles to determine exactly impossible, you can only calculate the probability of their values;

- discrete changes of physical quantities, for example, the energy of a microparticle has only some certain values.

Quantum mechanics still fraught with a term such as quantum cryptography, which is the fastest-growing technology that can change the world.Quantum cryptography aims to protect the secrecy of communications and information.Based on this cryptography certain phenomena of quantum physics and examines such cases where the information can be transferred using the object of quantum mechanics.It is here that using electrons, photons, and other physical assets is determined by a process of receiving and sending information.Due to quantum cryptography, you can create and design a communications system that can detect eavesdropping.

At the moment a lot of materials, offering the study of such concepts as quantum mechanics foundations and directions, as well as activities of quantum cryptography.To gain knowledge in this difficult theory, you should thoroughly study and delve into this area.Indeed, quantum mechanics - this is not an easy concept, which has been studied and proved the greatest scientists of many years.
