Not really. The Heisenberg Uncertainty Principle is a statement about the inability to precisely pin down the location and speed, simultaneously, of a particle, with our current technology. But this is a statement about our ability to abserve, not calculate. The reason you cannot know the speed and location of a particle by observation is that you must measure it's speed over some traveled distance, at which point you do not know the location anymore. It also is related to the fact that the act of observing a subatomic particle affects it. Since you cann't know both the starting location of a particle and its vector of motion, you can only predict the probabilitied of its location in the future (thus an electron probability field around the nuclei of an atom). In a way, you could say that Heisenberg's principle is the reason for quantum mechanics.
The Schroedinger equation is the equation used to determine these probabilities. However, it always produces at least two answers when you try to solve the equation. Obviously, we can observe and see which of the two really happens. But no one knows why one happens and not the other (assuming only two solutions).
Physicists have come up with two reasons to explain why one or the other actually occurs.
1) it must be observed by a conscious being. The act of observation causes the resolution of the equation.
2) Both occur at the point of resolution. One in one universe, and the other in another parrallel universe. Before the resolution, there is only one universe containing the potential for both (the tree has fallen and not at the same time), and the universe splits into two parrallel universes at the time of resolution.
Of course, Ockham's Razor suggests a third, simpler solution. We just haven't discovered the necissary correction to the equation that will allow us to come up with one answer. Or quantum physics (a cobbled together set of equations to explain things that are observed) doesn't work, and never will, and when the Grand Unified Theory is worked out, we can dispense with it.
