Yes, I get your point. See my edit above. Many thanks for your input

Computationally, I imagine it would be quite intensive to collect and calculate all the data required to find out if my mate, Bob, is headed to the pub at 8:30 pm this evening. This might have something to do with why physicists don't indulge in such empirical activities. Measuring the spin of all those electrons must be a daunting task, let alone the problems inherent in measuring anything to do with quantum mechanics.
