I see, in the most part. I just don't get the most juicy bit. How was Planck's constant arrived at and declared the limit of all detection and computation, regardless of the system in question? Why is tracking the momentum AND the position so difficult? Perhaps it is not regardless of the system - are we talking specifically about molecular/atomic interactions here? Also - is this (Planck's constant) an absolute upper tracking limit (dubious), or does it concede that new, unknown technologies may provide the key ? Do you? What about SI's ?
