The 'collapse of the wave function' is a mathematical term relating to a measurement being taken of a quantum system. NOT that they don't interact - this is wrong, the opposite in fact is true.

It is real world *predictions* from the mathematics that cannot be made, due to the uncertainty of knowing initial conditions - which is heisenberg uncertainty. This is the basis of the Schrodinger's Cat thought experiment which is a quantum system linked to a physical real world event.

Yes Heisenberg's uncertainty principle which pretty much states that with a decrease of error in locating the position of an electron, an increase of error exists in its direction/velocity...roughly speaking, I'm sure mycroft can elaborate.

aint that Heisenberg he's talkin bout

Probably the best explanation of Heisenberg's principle I've seen on the internet.

What the Bleep... is mostly a movie based around pseudo science and new age Ramtha philosophy. One must be careful about what you believe from this.

Quantum mechanics deals with small systems, and quantum effects (especially Heisenberg's Uncertainty Principle) are applicable only to matter on the scale of the de Broglie Wavelength. The movie exploits these effects by falsely implying that theses same effects (especially a wavefunction associated with an object and probability calculations concerning this object) are applicable to everyday objects, e.g. basketballs, humans, or fountains. This is simply not the case.

As the purported experts speak throughout the movie, they make several references to concepts, ideas, and alleged facts about quantum physics and other specific items. However, few of the scientists involved are actually professional physicists doing research in quantum mechanics, and one of those that does do such research, David Albert, has complained that his views were deliberately misrepresented.

The movie also fails to explain precisely how the theory of quantum mechanics actually proves any of the mystical or religious teachings found in the film. Statements from physicists are made which are then intercut with statements from medical doctors, people who have created their own religion, and others. No logical argument connecting the findings of quantum mechanics with the movie's core message is offered.

There is one singular argument that completely takes this proposed notion apart:
