Quantum Mechanics Intrinsic Uncertainty Nothing is Impossible Merely Improbable

Quantum Tunneling

The Principle of Uncertainty: An observer can not simultaneously know the position and momentum (velocity) of any particle to absolute certainty. Consider the following Case: I want to know the position of a particle but can only detect the particle by bouncing photons off of the particle BUT: this uncertainty is an intrinsic limit in nature, not an artifact of measurement. As soon as I have detected the spatial position of the particle, momentum has been transferred to the particle and its position has changed

Implications At any given time, one particle can’t precisely know where another particle is  quantum tunneling results  no energy barriers  Cat  exists as a quantum superposition until an observation is made (the Copenhagen interpretation).  God does not play dice  Einstein believed there were unaccounted for hidden variables that determine the state of the cat  Uncertainty is a fundamental part of nature! – nothing can be measured precisely or known precisely (Aristotle and Descartes go boom)
