The Uncertainty Principle is inherent in the properties of all wave-like systems, and that it arises in quantum mechanics simply due to the matter wave nature of all quantum objects. Thus, the uncertainty principle actually states a fundamental property of quantum systems, and is not a statement about the observational success of current technology. It must be emphasized that measurement does not mean only a process in which a physicist-observer takes part, but rather any interaction between classical and quantum objects regardless of any observer.
In quantum mechanics, the Uncertainty Principle, also known as Heisenberg's uncertainty principle, the more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa. This is a succinct statement of the "uncertainty relation" between the position and the momentum (mass times velocity) of a subatomic particle, such as an electron. This relation has profound implications for such fundamental notions as causality and the determination of the future behavior of an atomic particle. [1]
Essentially, the Heisenberg Uncertainty Principle is relative to the act of observation that collapses a wave potentiality that makes a situation, event or object become physical. When we observe EMF wave-forms we change the physical environment and how that is expressed in tangible ways.
Observer Effect
In science, the term observer effect refers to changes that the act of observation will make on a phenomenon being observed. This is often the result of instruments that, by necessity, alter the state of what they measure in some manner. A commonplace example is checking the pressure in an automobile tire; this is difficult to do without letting out some of the air, thus changing the pressure. This effect can be observed in many domains of physics. The observer effect on a physical process can often be reduced to insignificance by using better instruments or observation techniques.Historically, the observer effect has been confused with the uncertainty principle.[2]
The Uncertainty Principle has been frequently confused with the observer effect, evidently even by its originator, Werner Heisenberg. The uncertainty principle in its standard form actually describes how precisely we may measure the position and momentum of a particle at the same time — if we increase the precision in measuring one quantity, we are forced to lose precision in measuring the other. An alternative version of the uncertainty principle, more in the spirit of an observer effect,fully accounts for the disturbance the observer has on a system and the error incurred, although this is not how the term "uncertainty principle" is most commonly used in practice.[3]
