One of my favorite movies. A couple interesting books that I definitely reccomend are: The Dancing Wu-Li Masters - Gary Zukav The Tao of Physics - Fritjof Capra The Elegant Universe - Brian Greene The first two deal primarily with relationship between quantum theory and eastern philosophy. The last one is just an excellent primer on quantum physics in general. I will admit that as much as I am fascinated with the complexities of it all, the more I learn about it the less I seem to understand. It's a very paradoxical science. |

The key to understanding quantum physics is in accepting that you just can't visualise it in the same way you can other problems. It seemingly has no basis in the reality of the world we see around us. You have to be comfortable with the mathematics and have an understanding of the implications, consequences and experimental evidence for it all. Dave |

Not to mention the logical problems that are explained by Schrodingers Cat. Science is the discovery of fact. If the schrodigners cat experiment is taken as the definitive definition of quantum probability, we end up endorsing a science based on NOT knowing the facts.

Science isn't really based on knowing facts, it's about falsifiable hypotheses verified by repeatable experiment.
The predictions of quantum mechanics have been verified by experiment and until something better comes along, it's all we have to work with. In fact, it is "good enough" to enable practical use in the real world, specifically in the field of semiconductor devices (in a similar way to Newtonian mechanics being good enough in the field of sending stuff into space). As stated previously, the problems posed by Schrodinger's Cat only become a problem when attempting to apply classical physics to quantum mechanics. Take the maths and experimentation at face value (both of which have advanced considerably since the early 1900's) and such issues go away. Dave |

your use of 'at face value' is a bit ambiguous for me, but as far as i understood it collapse of the wave function is still somewhat problematic on the conceptual level, no? i agree that we've gotten very proficient at using quantum theory, but quantum effects still baffle us somewhat, especially when we can replicate them on macroscopic levels...
