The Uncertainty Principle
In the quantum world, the more you know, the less certain you can be!
This is what this principle is all about.
Proposed by Werner Karl Heisenberg in 1927, it states that we cannot determine both the position (x) and momentum (p) of a particle simultaneously.
The more precisely the position is determined, the less precisely the momentum is known, and vice versa.
Is this due to the observer?
My first thought was that “obviously” a property may change during measurement.
For example, the tools or methods used during measurement of a property, by the observer, may somehow disturb the system, and cause a change to the property being measured.
But Heisenberg’s uncertainty principle is not about that.
That would relate to the Observer effect (where the act of measurement may change the measured results of the experiment).
