Errors

AI Thread Summary

Distinguishing between systematic and statistical errors is crucial for accurate reporting in experiments. Systematic errors arise from consistent inaccuracies in measurement, while statistical errors stem from random variations. To effectively report results, one must conduct a thorough analysis of the experimental design. This allows for the proper identification and quantification of both types of errors. Understanding these distinctions enhances the reliability of the reported data.

I have one fast question. How can people in some results, distinguish between systematic and statistical errors? So that they can write: x= A^{\pm \delta B (stat)}_{\pm \delta C (syst)}?

I am trying to do the same with a report of mine, but I am not quite sure about whether that's possible or not.

It is possible, but you need to analyse the design of the experiment in detail.

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
