Many thanks for your reply. So I suppose that the difference between 1 cm and 32 cm is 5 doublings - which means that the radiation difference is 0.25 x 0.25 x 0.25 x 0.25 x 0.25 which would be about 1 mW from a 1 W cellphone. I suppose this is good news except that your brain would be receiving...
Dear All,
Please excuse my ignorance of physics. According to some Russian research 1 mW of microwave radiation could be considered safe for the brain (ie. it won't cause brain damage). I therefore considered that if a 1 W cellphone is damaging to the brain then perhaps it's a good idea to use...
It seems credible to me that in fact the future paths of the signal and idler photons (or rather their wave components) are already mapped in some way - and that is why the system reacts as a whole to a change to the environment.
Yes you're quite right. It seems that the results have a lot to do with the nature of the beam splitter. If two wave components hit the beam splitter (whether or not at the same time) then the photons segregate in order that their entangled counterparts give (or rather gave) interference...

Implication from a theoretical equation does not negate the positive benefits of getting empirical evidence to support the relevance of the equation - does it ?

Many thanks again. It appears from further reading that there are many interpretations of quantum mechanics which physicists have difficulty in deciding which one is the more appropriate.
In Kim et al 1999 the two wave components from an idler photon are well separated and...

Many thanks for your reply. However, if we choose not to observe which slit the photons went through - then I suppose the photons are free to produce interference patterns. In which case it is surprising to me that the interference patterns produced by two sets of photons cancel to...
Kim et al.
I thought that the signal photons were passing through a Young's slit type apparatus - in which case shouldn't they usually show an interference pattern overall ? - in other words why should the interference pattern only appear with the correlations ??
