Alan appears to have addressed this; which just leaves me needing to clarify:- Is the distinction between indeterminacy and uncertainty that uncertainty is something inherent to the system, while indeterminacy arises from external factors?
Other way round! I can state my weight is 110 kg with an uncertainty of 1 kg depending on clothing, time of day, etc. Likewise I can state my speed is x/y with an uncertainty depending on how I measured x and y, and I can truncate the calculation of e/π to any level of uncertainty I choose, but 0/0 is inherently indeterminate.
To take Jeffrey's example,I can set up a collimator to select photons coming from a radioactive source, with any degree of traje3ctory precision I choose, subject to the uncertainties of measurement and machining, but the time between the arrival of successive photons is inherently unpredictable because it is subject to the indeterminacy of the decay process.
