Heisenberg's Uncertainty Principle, an in depth explaination.

Allright, for those of you well versed in Quantum Physics, don't read this blog as you already know this information. Now for the rest of you here goes.
In a nutshell: In 1927 Werner Heisenberg discovered the uncertainty principle. What that shows is that you cannot determine exactly both the position and momentum of a particle simultaneously. So what exactly does this mean? Let's get in more detail.
Basically what it means is that a quantum entity, an electron for example, does not have a precise position and a precise velocity at the same time. The electron itself, for example, doesn't know both where it's at or where it is going.
This is based on the idea of wave-particle duality, which states: a wave does not exist "at a point" in the same way a particle can. This uncertainity is the whole nature of quantum reality.
If the world ran strictly by Newton's laws, then everything including the tiniest of particle's, would be determined in advance. Because of uncertainities existing at a sub-atomic level, The quantum world exists on statitistical probabilities rather than measurable certainities.
Now consider this:
Niels Bohr found that by an electrical attraction between a positive nucleus and the negative electron holds the electron in orbit. Bohr also stated that each electron has a fixed amount of energy that corresponds with its fixed orbit. When an electron absorbs energy it jumps to the next higher orbit rather than moving continously between orbits. This is known as the quantum theory of the atom.
However, if we define reality as that which can be observed by all, then we have to conclude that there is no determined movement of an electron around a nucleus. Another words taking Heisenberg literally, when you are not looking at the moon, it does not exist.
On a subatomic level we have to consider the possibility that there is a reality independent of observation and that there is an actual trajectory by the electron that cannot be measured. So the moon may be there after all and this is the essence of the Uncertainity Principle.
In conclusion, we as human beings have free will. Even god gives us this free will to make mistakes. We thereby learn from them. Physicists believe that free will can be traced back to the uncertainity built into the laws of quantum physics. Those of us that are avid lovers of quantum physics will read every single thing ever written about it.
When this blog began i specifically told those of you well versed in quantum physics not to read this. Out of 100 of you i dare to bet all 100 of you read it anyway. So i tell those of you, that you have been had!!
By reading this anyway, you demonstrated Heisenbergs Uncertainity Principle. For that i thank you. Nothing is certain and in the quantum physics world of the immeasurable, this principle is the epotimy of quantum physics itself.
Thank you for you attention, comment me PUBLICLY your thoughts. Stay tuned for more blogs on the world of the subatomic.
