How the bleep do their minds boggle?

This folm is comeing over here and has caused a bit of a stir in the USA. It's a New Agey sort of thing and I'm interested in how it engages popular science. The Guardian, very helpfully, have interviewed scientists about it and on the whole they're not impressed. One of the better comments was: "Scenes of the lad wanting to play basketball with Amanda may lead people to think that quantum properties, which describe matter at a very small scales, are equally applicable at large scales. In reality, quantum effects at large scales are extremely small and the motion of an object like a basketball is almost perfectly described by classical physics. Masaru Emoto's photographs of water, which Amanda comes across after missing the underground train, are even more confusing. Pictures we are shown from his dark-field microscope are presumably of tiny frozen water droplets. These patterns are dependent on the complex structure of ice and are influenced by any suspended matter in the water so it is hardly surprising that he obtained lots of interesting shapes. The idea that he can change these by thought processes or by sticking messages on bottles is ridiculous though. Another point I question is that Bleep seems to rule out the marrying of institutional religion with modern physics. In fact many religious people find that concepts of time and space, put forward by Einstein, support their religious beliefs."
All good points. Another point that is made twice by different people is that microphysical effects do not scale well, which is why we started out with Newtonian descriptions; they're the ones that work at a macro level. Quantum physics is not generally a way to make our universe more magical.
