The uncertainty principle is a theory that the more you know about the speed of an electron, the less you know about its position and vica versa

Is maybe an abstract noun?

Yes, the noun 'maybe' is an abstract noun, a word for an uncertainty; a word for a concept.'Maybe' can also function as an adverb


States that is imposible to know both the velocity and the position of a particle at the same time?

The heisenberg uncertainty principle is what you are thinking of. However, the relation you asked about does not exist. Most formalisms claim it as (uncertainty of position)(uncertainty of momentum) >= hbar/2. There is a somewhat more obscure and less useful relation (uncertainty of time)(uncertainty of energy) >= hbar/2. But in this relation the term of uncertainty of time is not so straightforward (but it does have an interesting meaning).


What symbol expresses uncertainty in a measurement?

All measurements are 'wrong', so we note how good our measurement technique is by providing a range either side of the measured value. Typically it's the plus-minus symbol ±, e.g. 35.8±0.4 kg. The greek lower case sigma is used in mathematical notation to represent uncertainty: σ.


What does the Heisenberg Uncertainty principle mean?

In any measurement, the product of the uncertainty in position of an object and the uncertainty in its momentum, can never be less than Planck's Constant (actually h divided by 4 pi, but this gives an order of magnitude of this law). It is important to note that this uncertainty is NOT because we lack good enough instrumentation or we are not clever enough to reduce the uncertainty, it is an inherent uncertainty in the ACTUAL position and momentum of the object.


Why is the uncertainty principle and the wave nature of particles unsignificant when describing the behavior of macroscopic objects but significant when describing the behavior of electrons?

The bird, is the word.
