uncertainty principle lies in the plane of quantum mechanics, however, to fully dismantle it, we turn to the development of physics in general.Isaac Newton and Albert Einstein, perhaps the most famous physicists in the history of mankind.First in the late XVII century, formulated the laws of classical mechanics, which are subject to all the bodies that surround us, the planet, subordinated to inertia and gravity.Development of the laws of classical mechanics resulted in the scientific world by the end of the XIX century to the view that all the basic laws of nature are already open, and a person can explain any phenomenon in the universe.
theory of relativity
It turned out that at that time was discovered only the tip of the iceberg, further research scientist planted a new, absolutely incredible facts.So, at the beginning of the XX century it was discovered that the propagation of light (which has a finite speed of 300 000 km / s) are not subject to the laws of Newtonian mechanics.According to the formulas of Isaac Newton, when a body or a wave emitted by a moving source, its speed will be equal to the speed of the source and own.However, the wave properties of the particles have a different nature.Numerous experiments have shown them that in electrodynamics, a young science at that time, working a completely different set of rules.Even then, Albert Einstein, together with the German theoretical physicist Max Planck introduced his famous theory of relativity, which describes the behavior of photons.However, we are now is important, not its essence as much as the fact that at this moment has been identified fundamental incompatibility between the two branches of physics, which combine, by the way, scientists are trying to this day.
birth of quantum mechanics
finally destroyed the myth of classical mechanics comprehensive study of the structure of atoms.The experiments of Ernest Rutherford in 1911 showed that the atom is composed of even smaller particles (called protons, neutrons and electrons).Moreover, they also refused to cooperate on the laws of Newton.The study of these tiny particles and generated new to the scientific world postulates of quantum mechanics.Thus, perhaps the ultimate understanding of the universe is not only and not so much in the study of the stars, and in the study of the smallest particles, which give an interesting picture of the world at the micro level.
Heisenberg Uncertainty Principle
In the 1920s, quantum mechanics made its first steps, but researchers only
realize what it implies for us.In 1927, German physicist Werner Heisenberg formulated his famous uncertainty principle, showing one of the main differences between the microcosm from our usual surroundings.It consists in the fact that it is impossible to measure both the speed and the spatial position of a quantum object has because when measuring we affect it, because the measurement itself and also by means of quanta.If absolutely banal: appreciating the object in the macro world, we see the reflection of a light on the basis of this make conclusions about it.But in quantum physics have effects of light photons (or other derivatives of measurement) has an effect on the object.Thus, the principle of uncertainty has caused understandable difficulty in studying and predicting the behavior of quantum particles.At the same time, interestingly, it can be measured separately speed or position of the body separately.But if we measure at the same time, the higher will be our data rate, the less we know about the real situation, and vice versa.
